Heat Lock Roofing System — Cut Your Roof Temperature by Up to 15°C
The solar-reflective thermal barrier coating for industrial roofs. Applied over your existing GI, asbestos, or concrete roof in 1–2 days — with zero production shutdown and proof you can measure before you pay.
The Heat Lock Roofing System is a solar-reflective thermal barrier coating by DUSH Italy, applied by Floorzy over existing industrial roofs in Bangalore. It reflects 65–80% of incident solar radiation and re-emits absorbed heat efficiently, reducing roof surface temperature by up to 15°C and indoor temperature by 5–10°C — installed in 1–2 days without stopping factory operations, with performance sustained for 5–7 years.
Key Takeaways
- Root-cause heat reduction: Heat Lock reduces how much solar heat your roof absorbs, instead of managing hot air after it forms.
- Works on existing roofs: GI sheet, pre-painted steel, asbestos cement, and concrete — no roof replacement or structural work.
- Measured performance: SR 0.65–0.80 solar reflectance, TE >0.85 thermal emittance, up to 15°C surface temperature reduction.
- Zero downtime: external application in 1–2 days while production continues inside.
- Bonus waterproofing: seals hairline cracks and pin-holes against monsoon leaks.
- Proof before purchase: free on-site demo with treated vs untreated panels under real sunlight.
What Is the Heat Lock Roofing System?
Heat Lock is a solar-reflective thermal barrier roof coating engineered by DUSH Italy for industrial buildings, applied in Bangalore and across Karnataka by Floorzy as the authorised applicator. Unlike conventional roof paint or generic “cool roof” products, Heat Lock is formulated with UV-stable binders and engineered inorganic pigments designed to sustain high solar reflectance under intense Indian sun for years — not months.
Applied directly over your existing roof, Heat Lock addresses the root cause of factory and warehouse overheating: the 85–95% of solar radiation that an untreated metal roof absorbs and converts into heat. By reflecting the majority of that radiation before it ever becomes heat, Heat Lock keeps the entire heat transfer chain — conduction through the roof, radiant heat below it, hot air accumulating inside — significantly cooler from the top down.
How Heat Lock Works
Heat Lock combines three thermal mechanisms in a single coating system:
1. High Solar Reflectance (SR 0.65–0.80)
The coating reflects 65–80% of incident solar radiation away from the roof — compared with roughly 5–15% reflectance on standard uncoated GI sheet. Less absorbed radiation means less heat generated at the surface in the first place.
2. High Thermal Emittance (TE >0.85)
Whatever heat the roof does absorb is re-released efficiently back toward the atmosphere as infrared radiation, rather than migrating downward into the building. High emittance is what makes the roof cool down quickly instead of storing heat.
3. Thermal Mass Barrier
A thermal mass component within the coating slows the transfer of residual heat through the roof membrane, buffering the interior against the peak of the afternoon heat load.

Installation Process
Heat Lock is installed in four steps, entirely on the exterior of the roof, with no interruption to operations inside the building:
- Free site survey & demo — Floorzy inspects your roof condition, measures existing surface temperature, and demonstrates treated vs untreated sample panels under real sunlight.
- Surface preparation — the roof is cleaned of dust, loose rust, and debris; minor defects are assessed. Roofs with major structural damage are flagged for repair before coating.
- Coating application — Heat Lock is applied across the roof surface by Floorzy’s trained team, typically completed in 1–2 days for a mid-sized industrial roof.
- Verification — post-application surface temperatures are measured so you can compare directly against the pre-treatment readings.
Maintenance Guide
Heat Lock is designed to be close to maintenance-free during its 5–7 year performance life. Recommended care is simple:
- Periodic rinse: an occasional water wash-down (or simply monsoon rain) clears accumulated dust, which helps sustain peak reflectance in dusty industrial zones.
- Annual visual check: a quick inspection for physical damage from foot traffic, fallen branches, or new roof penetrations (vents, cabling) added after coating.
- Top coat at 5–7 years: a lower-cost maintenance coat restores reflectance without full surface preparation or reapplication.
Industries & Applications
Heat Lock is applied across every major industrial building type in Bangalore and Karnataka where roof heat affects people, product, or power bills:
| Industry / Building Type | Primary Heat Problem Solved |
|---|---|
| Factories & manufacturing plants | Worker productivity loss and machinery thermal stress in peak summer |
| Warehouses & industrial sheds | Large roof-area heat gain affecting stored goods and staff |
| Logistics & fulfilment centres | Upper-rack heat and slowed pick rates during afternoon hours |
| Food processing units | Ambient temperature stability for product quality and safety |
| Textile mills | Heat-sensitive fibres and long manual shifts on the floor |
| Automobile component plants | Control-panel overheating and precision-process stability |
| Chemical plants | Reduced thermal stress on stored materials and equipment |
| Cold storage facilities | Lower external heat load on refrigeration, cutting compressor run-time |
Case Study: Textile Unit, Peenya Industrial Area
An 18,000 sq.ft GI sheet-roofed textile unit in Peenya, Bangalore, with around 120 workers on the shop floor.
Indoor temperatures of 48–52°C between April and June, driving absenteeism and an estimated 20–25% summer productivity loss.
Full-roof Heat Lock two-coat application, completed in two working days with zero production shutdown.
Roof surface dropped from 68°C to 53°C (−15°C); indoor temperature at head height fell from 49°C to 41°C, with reduced summer absenteeism the following year.
When comparing any “cool roof” or “heat-resistant” product, ask the vendor for two numbers: Solar Reflectance (SR) and Thermal Emittance (TE). These are measurable physical properties, not marketing terms. Heat Lock’s SR of 0.65–0.80 and TE above 0.85 are demonstrated on your site with an infrared thermometer before you commit — if a competitor can’t do the same, that tells you something.

Frequently Asked Questions
What is the Heat Lock Roofing System?
Heat Lock is a solar-reflective thermal barrier roof coating developed by DUSH Italy and applied by Floorzy in Bangalore. It’s applied directly over existing GI, pre-painted steel, asbestos cement, or concrete roofs and reduces roof surface temperature by up to 15°C by reflecting 65–80% of incident solar radiation.
How much does Heat Lock reduce roof temperature?
Up to 15°C at the roof surface under direct sunlight. Indoor air temperature typically drops 5–10°C depending on the building’s ventilation, roof area, and internal heat sources.
What roofs can Heat Lock be applied to?
GI (galvanised iron) sheet, pre-painted steel, asbestos cement, and concrete roofs in structurally sound condition. No roof replacement or structural modification is required.
How long does installation take?
A typical mid-sized industrial roof is completed in 1–2 days. Application is entirely external, so factory or warehouse operations continue without any shutdown.
How long does Heat Lock last?
Heat Lock sustains solar-reflective performance for 5–7 years under Indian outdoor conditions. After that, a lower-cost maintenance top coat restores performance without full reapplication.
Does Heat Lock also waterproof the roof?
Yes — it seals hairline cracks and pin-holes in ageing metal or asbestos roof sheets, reducing water ingress during monsoon. Roofs with major structural damage need repair before coating.
How much money can Heat Lock save on electricity?
Where cooling systems are installed, Floorzy has reported annual energy savings of roughly ₹35,000–₹55,000 for a 10,000 sq.ft factory, with cooling energy reductions around 30% in relevant cases. Savings scale with roof area and cooling load.
Can I see proof before purchasing?
Yes. Floorzy conducts a free on-site demonstration using treated and untreated sample panels measured under real sunlight with an infrared thermometer, so you can verify the temperature difference on your own roof before any decision.
Is Heat Lock better than white roof paint?
For sustained performance, yes. Standard white paint chalks and loses reflectance within 12–18 months, while Heat Lock’s UV-stable binders and engineered inorganic pigments are designed to maintain 65–80% solar reflectance for 5–7 years.
Does Heat Lock work on old or rusted roofs?
It can be applied to ageing roofs in structurally sound condition after surface preparation, and it helps seal minor corrosion points and pin-holes. Major rust-through or structural damage needs repair first — assessed during the free site survey.

What Our Customers Say
“Our GI sheet roof was touching 68°C every afternoon in May. After Floorzy applied Heat Lock, we measured 52°C on the same spot the very next week. The floor workers noticed the difference immediately — especially on the top mezzanine level where it used to be unbearable. Two days of work, not a single hour of production lost.”
“I had tried white paint twice before. Both times it faded within a year and we were back to square one. The Floorzy team brought sample panels to our warehouse, measured both with an infrared thermometer in front of me, and the gap was 14°C — right there on my own roof. That demo is what convinced me. One summer later, my AC bills are noticeably lower.”
“We run an auto-components plant with CNC lines that were throwing overheat alerts every summer afternoon. Since Heat Lock was applied, we haven’t had a single panel shutdown due to heat this season. The monsoon leak we had near the ridge is also sealed. Honestly should have done this three years ago instead of patching the roof every year.”
