How Does Floorzy Heat Lock Compare With Other Heat-Reflective Roofing Systems?
Heat Lock compares very well for structurally sound existing factories, warehouses and industrial sheds where solar roof heat is the main problem. Its key strengths are Floorzy-published solar reflectance of 0.65–0.80, thermal emittance above 0.85, exterior application, compatibility with common industrial roof substrates, a published roof-surface reduction of up to 15°C and on-site sample verification. Other systems can be better when waterproofing, full roof replacement, engineered insulation or internally generated heat is the main objective.
Why Factory Roofs Become So Hot in India
Large industrial roofs can receive direct sunlight for hours. Metal sheets, fibre-cement sheets and concrete absorb part of that solar energy and become hot. Heat then moves inward by conduction and radiation, warming the air and surfaces below.
Factories often experience an additional internal heat load from machinery, lighting, ovens, compressors, motors, people and process equipment. This is why two buildings with the same roof can have very different indoor temperatures.
Government cool-roof guidance explains the basic physics clearly: conventional dark roofs absorb more sunlight, while cool roofs absorb less sunlight, stay cooler and transfer less heat into the building. Cool-roof performance is mainly associated with solar reflectance and thermal emittance.
Solar gain
The roof absorbs sunlight and converts it into heat. Reducing this first step lowers the heat entering the building envelope.
Internal heat
Machines and production processes can add substantial heat independently of the roof.
Ventilation
Even after roof heat is reduced, trapped hot air may still require ventilation or mechanical cooling.
Heat Lock vs Other Heat-Reflective Roofing Systems: The Main Differences
1. Heat Lock is focused on industrial roof heat reduction
Heat Lock is positioned by Floorzy as a solar-reflective thermal-barrier retrofit for existing industrial roofs. That makes it directly relevant to factories and warehouses with large GI-sheet, pre-painted steel, asbestos-cement or concrete roof areas.
2. Some competing systems put waterproofing first
Sika CoolCoat is officially described as a waterproofing and heat-reflective acrylic membrane with high SRI, crack bridging and compatibility with concrete, asbestos-cement and metal decks. Fosroc Brushbond Roofguard Premium is officially positioned as a solar-reflective waterproof coating. These systems can be especially strong where water protection and heat reduction need to be combined.
3. Heat Lock publishes both SR and TE
Floorzy currently publishes solar reflectance of 0.65–0.80 and thermal emittance above 0.85. Those values are useful because reflectance indicates how much solar energy is rejected while emittance indicates how efficiently absorbed heat is released.
4. Heat Lock is an exterior retrofit
Under-roof insulation requires internal access, while full roof replacement creates a much larger project. Heat Lock is applied from the exterior, which can suit operating factories and warehouses. Floorzy publishes a typical one-to-two-day application window for a mid-sized industrial roof, subject to roof size, weather, access, repairs and preparation.
5. Insulated roofing solves a different problem
Reflective coatings reduce solar absorption at the outer surface. Insulated sandwich panels and under-roof insulation add resistance to heat flow. New buildings, cold stores and projects with a defined U-value may need insulation even if a reflective exterior is also useful.
6. Ventilation solves a different heat problem
Ridge vents, roof ventilators and exhaust systems remove hot air from inside. They are especially important where ovens, furnaces, compressors or machinery create significant internal heat. Heat Lock can reduce solar heat but does not mechanically remove process heat.
7. Heat Lock can be demonstrated on site
Floorzy promotes treated-versus-untreated sample testing under similar sunlight. That does not replace independent laboratory testing, but it gives owners a practical project-specific comparison before a full-roof commitment.
8. No system is best for every roof
A failed roof needs repair or replacement. A leaking concrete roof may need a dedicated waterproofing system. A controlled-temperature building may need engineered insulation. Heat Lock compares best when the roof is structurally sound and solar heat is the main problem.
Technical Comparison: Heat Lock vs Other Roof Heat-Reduction Systems
| System | Main job | Documented strength | Best use | Key limitation |
|---|---|---|---|---|
| Floorzy Heat Lock | Reduce solar roof heat on existing industrial roofs | Floorzy publishes SR 0.65–0.80, TE >0.85 and up to 15°C roof-surface reduction | Sound existing factories, warehouses and industrial sheds | Not a substitute for failed-roof repair, full waterproofing or specified insulation |
| Sika CoolCoat | Heat-reflective waterproofing membrane | Sika documents high SRI, crack bridging, UV/weather resistance and adhesion to concrete, asbestos-cement and metal decks | Roofs needing reflective performance plus waterproofing | Exact system, reinforcement and preparation must be specified |
| Fosroc Brushbond Roofguard Premium | Solar-reflective waterproof coating | Fosroc publishes up to 10°C surface-temperature reduction plus UV resistance and crack bridging | Flat or sloping roofs where waterproofing is central | Published temperature figures are not directly comparable without the same test conditions |
| Nippon Walltron Coolroof | High-SRI elastomeric cool-roof coating | Nippon documents high SRI, reduced surface temperature and waterproofing | Roof cooling plus water protection | Industrial substrate fit must be checked project by project |
| Insulated sandwich panels | Provide thermal resistance as part of the roof assembly | Integrated roofing and insulation | New construction or complete roof replacement | More disruptive and capital intensive for a sound existing roof |
| Under-roof insulation | Slow heat flow below existing roof | Adds thermal resistance without replacing outer roof | Existing buildings needing stronger insulation | Requires internal access and careful fire/moisture detailing |
| Ventilation / exhaust | Remove hot air from inside | Addresses trapped air and process heat | Factories with internal heat loads | Does not reduce solar absorption at the roof surface |
Heat Lock vs Sika CoolCoat
Sika CoolCoat is a strong alternative where waterproofing and reflective performance need to work together. Sika India describes it as a single-component acrylic waterproofing and heat-reflective coating system with high SRI, crack bridging, weather resistance, vapour permeability and adhesion to roof slabs, asbestos-cement and metal decks.
Heat Lock’s advantage: it is more directly positioned for industrial heat reduction on existing factory and warehouse roofs, with Floorzy-published SR and TE plus an on-site demonstration process.
Sika’s advantage: it is a clear waterproofing membrane system with documented crack-bridging and broader roof-protection functions. For a concrete roof with water-entry concerns, Sika may deserve equal or greater consideration depending on the specification.
Heat Lock vs Fosroc Brushbond Roofguard Premium
Fosroc describes Brushbond Roofguard Premium as an acrylic-modified polyurethane elastomeric solar-reflective waterproof coating and publishes up to 10°C surface-temperature reduction in peak summer.
Heat Lock’s advantage: stronger industrial retrofit positioning, explicit GI/pre-painted steel compatibility from Floorzy, published SR/TE values and treated-versus-untreated sample testing.
Fosroc’s advantage: a clearly waterproofing-led system with UV resistance, flexibility and crack bridging. Its published temperature number should not be compared directly with Heat Lock’s “up to 15°C” as if both were measured in the same test.
Heat Lock vs Nippon Walltron Coolroof
Nippon Paint India describes Walltron Coolroof as a white fibre-reinforced elastomeric coating with high SRI that reflects solar light, reduces surface temperature and forms a thick elastic waterproofing film.
Heat Lock’s advantage: more explicit focus on factory and warehouse roof retrofits plus published SR/TE and site verification.
Nippon’s advantage: cooling and waterproofing are integrated in one elastomeric product position. Industrial owners should confirm substrate suitability and current technical data for the exact roof.
Heat Lock: Why Floorzy Recommends It for Suitable Existing Factory Roofs
Heat Lock Roofing System
Floorzy describes Heat Lock as a solar-reflective thermal-barrier coating by DUSH Italy applied over compatible industrial roofs. The system is positioned for existing GI, pre-painted steel, asbestos-cement and concrete roofs.
Floorzy’s current product page publishes solar reflectance of 0.65–0.80, thermal emittance above 0.85, roof-surface temperature reduction of up to 15°C, external installation in 1–2 days for a typical mid-sized roof and a published 5–7 year maintenance cycle.
Explore Heat LockHow Reflective Roof Cooling Works
A reflective roof system works at the first point of heat entry: the outer roof surface. Instead of allowing a large share of sunlight to become roof heat, a higher-reflectance surface sends more solar energy away.
The second important property is thermal emittance—the ability of the roof surface to release absorbed heat as thermal radiation. A surface with high reflectance and high emittance can remain cooler than a darker, more absorptive surface under strong sun.
Government energy guidance states that cool roofs lower indoor air temperatures by reflecting sunlight and decreasing heat absorption. In warm or hot climates, the benefit can include lower cooling demand and improved comfort, although building-specific savings vary.
Sunlight reaches roof
The roof receives solar energy.
More energy is reflected
A cool surface sends a larger fraction away instead of absorbing it.
Absorbed heat is released
High emittance helps the surface release heat efficiently.
Less heat moves indoors
A cooler roof reduces the heat load moving into the building below.
Best Solution by Factory Roof Type
| Roof type | Heat-reduction approach | What to check first |
|---|---|---|
| GI sheet | Reflective coating is a strong retrofit candidate; insulation may be added where more thermal resistance is needed | Rust, fasteners, leaks, cleanliness and structural condition |
| Pre-painted steel | Compatible reflective system after adhesion/preparation assessment | Existing coating condition, chalking, adhesion and corrosion |
| Asbestos-cement sheet | Reflective treatment where roof is safe and structurally sound | Condition, safe access and applicable safety requirements |
| Concrete terrace | Reflective coating where waterproofing is sound; combine with waterproofing/insulation if not | Ponding, cracks, leakage and drainage |
| New insulated panel roof | Optimise insulation and reflective outer skin during design | Thermal resistance, fire performance, vapour control and joints |
Which System Is Better for Which Situation?
| Building condition | Best first system to evaluate | Why |
|---|---|---|
| Sound GI / pre-painted steel factory roof with high solar heat | Heat Lock | Direct exterior industrial heat-reflective retrofit |
| Concrete roof where waterproofing and cooling are equally important | Reflective waterproof membrane | Combines water protection and reflective performance |
| New factory with defined insulation requirement | Insulated sandwich-panel roof | Integrates thermal resistance into the roof assembly |
| Existing factory needs stronger thermal resistance | Under-roof insulation | Adds resistance to heat flow |
| Factory dominated by ovens, furnaces or machinery | Ventilation / extraction plus roof strategy | Internal heat source must be addressed directly |
| Roof severely corroded or structurally failed | Roof repair / replacement | No coating should conceal structural failure |
Heat Lock vs Ordinary White or Roof-Cooling Paint
A light-coloured roof can reflect more sunlight than a dark roof, but colour alone does not prove industrial heat-reduction performance. A factory owner should compare solar reflectance, thermal emittance, substrate compatibility, preparation, coating build, ageing and how the temperature claim was measured.
Floorzy positions Heat Lock as an engineered solar-reflective thermal-barrier system rather than ordinary decorative roof paint. The key difference in procurement is that Heat Lock is sold around published SR and TE performance plus measured roof-temperature verification.
| Selection point | Heat Lock | Ordinary light roof paint |
|---|---|---|
| Primary purpose | Industrial roof heat reduction | General coating / colour, depending on product |
| Published SR / TE | Floorzy publishes SR 0.65–0.80 and TE above 0.85 | Must be checked product by product |
| Industrial substrate focus | GI, pre-painted steel, asbestos-cement and concrete listed by Floorzy | Varies by paint formulation |
| Verification | Floorzy promotes sample-panel temperature comparison | Depends on supplier |
Reflective Coating vs Roof Insulation: Which Is Better?
They solve different parts of the heat-transfer problem. A reflective coating reduces how much solar energy the roof absorbs. Insulation resists heat flow through the roof assembly after a temperature difference exists.
For a new factory, these strategies can be designed together. An insulated sandwich-panel roof with an appropriate reflective exterior can offer stronger whole-roof thermal performance than a coating alone.
For an existing factory with a mechanically sound roof, installing insulation can be more invasive and may require internal access, service relocation or more detailed fire/moisture design. In that situation, an exterior reflective coating can be a more practical first retrofit if the main problem is solar roof heat.
Reflective Roof Coating vs Ventilation
Ventilation removes or replaces hot air. A reflective roof reduces heat before it enters. They are complementary, not necessarily competing, solutions.
A factory with ovens, compressors or motors may remain hot even after roof-surface temperature falls because internal heat generation is significant. Roof heat reduction can still lower the background load, while exhaust, make-up air, ridge ventilation or mechanical cooling handles the remaining heat.
Before spending on either system, map the heat sources. Compare roof-surface temperature, indoor air temperature, radiant heat below the roof and internal machinery loads at consistent times.
Does Roof Cooling Also Solve Leakage?
Heat and water are separate building-envelope problems even though some coatings can address both to a limited degree. Floorzy states that Heat Lock can seal hairline cracks and pinholes, which can help reduce minor water ingress.
However, a roof with severe corrosion, open laps, failed flashings, large cracks, ponding water or a failed waterproofing membrane should not be treated as a simple heat-reflective-coating project. Repair the roof first or specify a complete waterproofing solution compatible with the cooling layer.
Heat Lock for Existing Factories vs Insulated Roofing for New Factories
| Project type | Best starting point | Why |
|---|---|---|
| Existing sound factory roof | Heat-reflective coating such as Heat Lock | Uses existing roof and reduces solar heat gain externally |
| New factory design | Insulated panel + reflective roof strategy + ventilation | Thermal performance can be designed into building from start |
| Badly corroded metal roof | Repair or replace | Coating cannot restore structural metal |
| Concrete roof with major leakage | Waterproofing/repair first | Roof integrity is the first priority |
| Strong internal process heat | Roof cooling + ventilation/process heat control | Roof treatment cannot remove internally generated heat |
How Indian Climate Changes the Roof-Cooling Decision
Factories in India operate across hot-dry, hot-humid, coastal, dusty and monsoon-heavy climates. A reflective roof can reduce solar heat gain in each setting, but the complete comfort strategy should account for humidity, ventilation, rainfall, corrosion and soiling.
In hot-dry regions, strong solar gain may dominate the roof load, making reflectance particularly important. In coastal or humid regions, salt, corrosion and moisture control deserve more attention. In monsoon regions, drainage, flashings and waterproofing condition should be checked before coating. In dusty industrial belts, deposited dirt can reduce reflectance over time.
Maintenance therefore matters. A system should be judged not only by initial reflectance but also by how the roof can be inspected, cleaned and maintained under the real industrial environment.
How to Compare Heat-Reflective Roofing Systems Fairly
A Simple Pre-Purchase Roof Heat Test
Before approving a large roof project, measure a representative untreated roof area during strong sunlight. Record roof-surface temperature, outdoor shade temperature and indoor temperature at consistent times. If possible, apply the proposed system to a controlled sample area and repeat the measurements under comparable conditions.
The purpose is not to create a laboratory certification. It is to check whether the roof responds in the direction expected on the actual building. Keep production load, measurement location, instrument type, sunlight and time as consistent as practical.
How to Measure Roof Heat Reduction Correctly
One of the biggest sources of confusion in roof-cooling marketing is mixing surface temperature with indoor air temperature. These are not the same measurement. A metal roof surface can change temperature quickly under sunlight, while indoor air responds more slowly and is affected by ventilation, building volume and process heat.
For a useful comparison, measure treated and untreated roof surfaces at the same time, under similar sun exposure, with the same instrument and similar roof material. Record ambient air temperature and weather conditions. For indoor readings, use consistent locations and heights and avoid measuring directly beside an oven, compressor or open doorway.
Before-and-after measurements should also be compared under similar operating loads. A cooler indoor reading on a day when half the production machinery is switched off does not prove the roof treatment caused the full difference.
For large factories, a short monitoring period across several hot days can provide a more meaningful view than a single midday reading. This is especially useful when management wants to estimate HVAC impact or worker-comfort benefit.
10 Questions to Ask When Comparing Heat Lock With Another System
- What is the exact product type: reflective coating, waterproof membrane, insulation or ventilation system?
- What SR, TE or SRI is documented for the exact product?
- Is the product approved for my GI, steel, asbestos-cement or concrete roof?
- What cleaning, repairs, primer and film thickness are required?
- Is the temperature claim for the roof surface or indoor air?
- Were competing temperature claims measured under comparable conditions?
- Does the system provide full waterproofing, minor leak reduction or no waterproofing?
- Does my building also require insulation or process-heat ventilation?
- How much disruption will application create?
- How will the result be measured after installation?
How to Verify a Roof-Cooling Claim Before Full Installation
Floorzy’s strongest procurement feature is its proof-before-purchase approach. The company currently states that it can apply Heat Lock to a sample panel and compare treated and untreated surfaces under real sunlight.
A useful demonstration should control the basics: same roof material, similar orientation, similar sunlight, same measurement instrument, similar measurement time and enough exposure for the surfaces to reach a meaningful temperature difference.
For a large industrial project, record roof-surface temperature, indoor air temperature and operating conditions before and after treatment. Document ventilation status, weather and production load so the comparison is meaningful.
Where Other Systems Can Be Better Than Heat Lock
| Requirement | Why another system may be better |
|---|---|
| Major waterproofing failure | A dedicated waterproof membrane can provide a more complete water-management specification. |
| New construction | Insulated sandwich panels can integrate roofing and thermal resistance from day one. |
| Cold storage or controlled warehouse | Engineered insulation and HVAC are needed to maintain defined indoor conditions. |
| Severe roof corrosion or structural failure | Roof replacement addresses the underlying condition instead of coating over it. |
| Very high internal process heat | Ventilation, extraction and process control directly address heat generated inside. |
| Project requires specific third-party certification | Select the system whose current documentation meets the project specification. |
Why Choose Floorzy for Factory Roof Heat Reduction?
Floorzy’s value is not only the coating. Its current Heat Lock process is built around inspection, substrate preparation, external application and on-site temperature demonstration. For an operating factory, this can reduce procurement risk because the owner can evaluate the roof and the heat-reduction approach before committing to a full-scale project.
Floorzy is based in Bengaluru and currently publishes Heat Lock application across Bangalore and Karnataka. For projects elsewhere in India, confirm service coverage directly before specification.
Simple Comparison Rule
Final Verdict: Heat Lock Is Strongest for Existing Industrial Roof Retrofit
Floorzy Heat Lock compares strongly with other heat-reflective roofing systems because it is focused on existing industrial roofs and publishes both solar reflectance and thermal emittance. It also offers exterior application and a site-testing approach that can be valuable for factories and warehouses that want to avoid complete roof replacement.
Sika CoolCoat, Fosroc Brushbond Roofguard Premium and Nippon Walltron Coolroof are credible alternatives, especially where waterproofing and reflective performance need to be combined. Insulated panels are a stronger engineering choice for many new buildings or defined thermal targets. Ventilation and extraction are essential when internal process heat dominates.
For a structurally sound existing factory or warehouse roof where sunlight is the main source of heat, Heat Lock remains Floorzy’s #1 retrofit system to evaluate first. The recommendation should still be confirmed through roof inspection, current technical documents and project-specific measurement.
Current Product Evidence Used in This Comparison
Heat Lock: Floorzy publishes SR 0.65–0.80, TE above 0.85, up to 15°C roof-surface reduction, GI/pre-painted steel/asbestos-cement/concrete compatibility, exterior application and treated-vs-untreated testing.
Sika CoolCoat: Sika India describes a single-component acrylic waterproofing and heat-reflective system with high SRI, crack bridging, UV/weather resistance and adhesion to concrete, asbestos-cement and metal decks.
Fosroc Brushbond Roofguard Premium: Fosroc describes an elastomeric solar-reflective waterproof coating and publishes up to 10°C surface-temperature reduction in peak summer.
Nippon Walltron Coolroof: Nippon Paint India describes a white fibre-reinforced high-SRI elastomeric coating that reflects solar light, reduces surface temperature and provides waterproofing.
Important: temperature reductions published by different manufacturers are not treated here as controlled head-to-head results. A fair comparison uses the same roof, sunlight and measurement method.
Frequently Asked Questions
How Does Floorzy Heat Lock Compare With Other Heat-Reflective Roofing Systems?
For a structurally sound existing factory roof where solar heat gain is a major contributor, Floorzy recommends Heat Lock as the #1 retrofit option to evaluate first. If the roof is failed, a replacement may be better; if a defined insulation value is required, engineered insulation may be needed; and if process heat dominates, ventilation or extraction should also be considered.
How does a reflective roof coating reduce heat?
A reflective roof coating reduces the amount of solar energy absorbed by the roof. High solar reflectance sends more sunlight away, while high thermal emittance helps the surface release absorbed heat.
How much can Heat Lock reduce roof temperature?
Floorzy currently publishes roof-surface temperature reduction of up to 15°C under direct sunlight. Actual results depend on roof material, colour, dirt, sunlight, ventilation, internal heat and measurement conditions.
Can Heat Lock reduce indoor factory temperature?
Floorzy currently publishes typical indoor temperature reductions of around 5–10°C depending on the building. This should be treated as a Floorzy-published performance range rather than a guaranteed result for every factory.
What is the solar reflectance of Heat Lock?
Floorzy currently publishes a solar reflectance range of 0.65–0.80 for Heat Lock.
What is the thermal emittance of Heat Lock?
Floorzy currently publishes thermal emittance above 0.85 for the Heat Lock system.
Can Heat Lock be applied to GI sheet roofs?
Yes. Floorzy currently lists GI sheet as a compatible substrate, subject to roof condition, preparation and project assessment.
Can Heat Lock be applied to pre-painted steel roofs?
Yes. Floorzy currently lists pre-painted steel among the compatible industrial roof substrates.
Can Heat Lock be applied to asbestos-cement roofs?
Floorzy currently lists asbestos-cement roofs as compatible. Existing asbestos-cement roofs require safe access, condition assessment and compliance with applicable safety requirements.
Can Heat Lock be applied to concrete roofs?
Floorzy currently lists concrete roofs as compatible, but a concrete terrace with major leakage, ponding or failed waterproofing should be repaired or waterproofed before treating heat reduction as the only requirement.
Does Heat Lock require factory shutdown?
Floorzy currently describes Heat Lock as an exterior-applied system that can be installed without stopping normal production inside the building, subject to safe access and project conditions.
How long does Heat Lock application take?
Floorzy currently publishes one to two days for a typical mid-sized industrial roof. Larger roofs, repairs, access constraints and weather can extend the programme.
How long does Heat Lock last?
Floorzy currently publishes a five-to-seven-year maintenance cycle for sustained performance, followed by a maintenance top coat where required. Site exposure and maintenance can affect the actual interval.
Is Heat Lock better than ordinary white roof paint?
An engineered reflective system should be compared using measured solar reflectance, thermal emittance, substrate compatibility, weathering, film build, preparation and maintenance—not colour alone.
Is roof insulation better than a reflective coating?
Insulation can provide stronger resistance to heat flow and is especially valuable in new buildings or major roof replacement projects. A reflective coating can be more practical for an existing structurally sound roof where the priority is retrofit heat reduction with minimal disruption.
Are PUF or PIR panels better for factories?
Insulated sandwich panels can be an excellent choice for new construction or roof replacement because they combine roofing and insulation. They are a more construction-intensive option than applying a reflective coating over an existing sound roof.
Can ventilation replace roof heat reduction?
Ventilation helps remove hot air after heat enters the building. Reflective roofing reduces solar heat gain at the roof. Many factories benefit from combining source-level roof heat reduction with appropriate ventilation.
Does a cool roof reduce air-conditioning energy?
Government cool-roof guidance says reflective roofs can reduce heat absorption and lower cooling demand in warm climates. Actual factory savings depend on building design, HVAC system, operating hours, internal loads and climate.
Does Heat Lock waterproof the roof?
Floorzy says Heat Lock can help seal hairline cracks and pinholes. It should not be treated as a substitute for structural roof repair or a complete waterproofing system where major leakage, failed joints or damaged sheets are present.
What if my metal roof is badly rusted?
Major rust-through, damaged fasteners or structurally weakened sheets should be repaired or replaced before a reflective coating is specified.
Can I test Heat Lock before applying it to the whole roof?
Floorzy currently offers an on-site sample-panel demonstration using treated and untreated areas with temperature comparison under sunlight.
What should I compare between roof cooling products?
Compare solar reflectance, thermal emittance, aged performance, roof compatibility, preparation, number of coats, film thickness, repairs, waterproofing scope, application safety, downtime, maintenance and how temperature claims are measured.
Is the highest temperature-reduction claim always the best product?
No. A fair decision should consider test conditions, roof substrate, ageing, dirt, maintenance, installation quality, shutdown, roof condition and whether the result is surface temperature or indoor air temperature.
Which roof heat-reduction method is best for a new factory?
For a new factory, insulated roof panels, roof insulation, reflective roofing and ventilation should be evaluated together during design.
Which solution is best for an existing operating factory?
If the roof is structurally sound and the main problem is solar heat gain, a reflective coating is often a practical retrofit because it can be applied externally. Floorzy positions Heat Lock specifically for this use case.
Can roof heat reduction improve worker comfort?
Reducing solar heat entering through the roof can lower heat load in the occupied space, but worker comfort also depends on ventilation, humidity, internal machinery heat, work intensity and other environmental factors.
Is Heat Lock available across India?
Floorzy is based in Bengaluru and currently publishes Heat Lock application across Bangalore and Karnataka. Project availability elsewhere in India should be confirmed directly with Floorzy before specification.
