Quick Answer — What is Heat Lock and How Does It Work?

Heat Lock is a solar-reflective, thermal barrier roof coating by DUSH Italy applied to industrial roof surfaces. It reflects 65–80% of incident solar radiation before it is absorbed by the roof material and converted to heat — reducing roof surface temperature by up to 15°C under direct sunlight and measurably improving indoor working conditions.

🌡️
Up to 15°C Reduction
Measurable roof surface temperature reduction — demonstrated on sample panels at your site before installation.
⚡
30% Energy Savings
Reduced heat load lowers AC running costs. Annual savings of ₹35,000–₹55,000 for a 10,000 sq.ft factory.
👷
Higher Productivity
Studies show 15–25% productivity losses in hot facilities during Indian summer months.
💧
Waterproofing Bonus
Seals hairline cracks and pin-holes in corroded roof sheets — reducing monsoon water ingress.
🏭
Zero Disruption
Applied to the exterior roof — factory operations continue completely normally during installation.
📊
Proven ROI
Energy and productivity savings typically exceed installation cost within 12–18 months.

The Science

How Heat Lock Works

Standard GI roofs have solar absorptance of 85–95% — meaning they absorb almost all solar energy that falls on them. During Indian summer, this heats roof surfaces to 65–75°C at peak hours.

Heat Lock uses three mechanisms simultaneously:

Solar Reflectance (SR): 0.65–0.80
Reflects 65–80% of total solar radiation — vs 5–15% for standard GI roofs
Thermal Emittance (TE): >0.85
Efficiently emits absorbed energy back to atmosphere rather than into the building
Thermal Mass Component
Slows transfer of any residual heat through the roof membrane into the interior air space

Case Study

Textile Unit, Peenya Industrial Area, Bangalore

📋 18,000 sq.ft GI Sheet Roof | 120 Workers
The Challenge

April–June indoor temperatures reaching 48–52°C. Significant absenteeism, heat-related health incidents, and estimated 20–25% productivity loss during summer months.

The Solution

Heat Lock 2-coat system on complete 18,000 sq.ft GI roof. Completed in 2 working days with zero production shutdown. No disruption to 120 factory workers.

Results
  • Roof surface: 68°C → 53°C (-15°C)
  • Indoor at head height: 49°C → 41°C
  • Worker comfort significantly improved
  • Summer absenteeism reduced vs prior year
  • "The difference was visible immediately"

FAQs

Heat Lock Questions

What is Heat Lock and who makes it?
Heat Lock is a solar-reflective, thermal barrier roof coating formulated by DUSH Italy — an Italian specialist manufacturer of functional coating systems. Floorzy Makeover is an authorised applicator of Heat Lock in Bangalore and Karnataka.
How much can Heat Lock reduce the temperature inside my factory?
Heat Lock reduces roof surface temperatures by up to 15°C under suitable direct sunlight conditions. The corresponding indoor air temperature reduction typically ranges 5–10°C depending on the building's ventilation, dimensions, and heat sources. Floorzy invites every client to measure this on sample panels before installation.
Is the temperature reduction guaranteed?
Floorzy does not provide a guaranteed figure because actual reduction depends on factors outside our control. However, Floorzy brings sample panels to your facility so you can measure the temperature difference yourself under sunlight before committing. The physics of solar reflection are consistent and measurable.
What is the cost of Heat Lock in Bangalore?
Heat Lock installation is typically priced ₹30–55 per square foot of roof area for the complete 2-coat application including materials, access equipment, and labour. Volume efficiencies apply for large projects above 20,000 sq.ft. Contact Floorzy for a free site assessment and quotation.
Can we continue factory operations during installation?
Yes. Heat Lock is applied to the exterior roof surface. Factory operations continue normally inside the building throughout the complete installation process. This is one of Heat Lock's most significant practical advantages over internal insulation or false ceiling solutions.
How long does Heat Lock last?
Heat Lock delivers consistent performance for 5–7 years under Indian outdoor conditions before a maintenance top coat is recommended. This maintenance coat is significantly less expensive than the original installation as surface preparation requirements are minimal.
Does Heat Lock also waterproof the roof?
Yes. Heat Lock seals hairline cracks, pin-holes, and minor joint openings in metal roof sheets — the primary water ingress points during monsoon. For roofs with significant structural damage or large holes, repairs must be made before application.
How does Heat Lock compare to painting the roof white?
Standard white roof paint provides some reflectance benefit but degrades rapidly (12–18 months) as it accumulates dirt and chalks. Heat Lock is specifically formulated with engineered inorganic pigments and UV-stable binders to maintain high solar reflectance significantly longer than standard paint products.
Can Heat Lock be applied over an existing roof coating?
Yes. Heat Lock can be applied over existing roof coatings in sound condition. If existing coatings are flaking or delaminating, they must be stabilised or removed first. Floorzy assesses existing coating condition during the site survey and advises accordingly.
What roof types is Heat Lock compatible with?
Heat Lock is compatible with galvanised steel (GI sheet), pre-painted or colour-coated steel, asbestos cement sheets, and concrete flat roofs. It is not appropriate for clay tile or slate roofing. Floorzy confirms compatibility with your specific roof material during the assessment.
What is the cost of Heat Lock roof coating in Bangalore?
Heat Lock roof coating in Bangalore by Floorzy is priced from ₹30–55 per square foot of roof area for the complete 2-coat application — including materials, access equipment, surface preparation, and application. For a typical 5,000 sq.ft factory roof, total cost is approximately ₹1.5–2.75 lakh. Volume pricing applies for roofs above 20,000 sq.ft. Contact Floorzy for a free site assessment.
How to reduce factory roof heat in India without air conditioning?
The most effective and economical way to reduce factory roof heat in India without adding air conditioning is Floorzy's Heat Lock solar reflective roof coating. Applied to existing GI or asbestos roof sheets, it reflects 65–80% of solar radiation — reducing roof surface temperature by up to 15°C and interior temperature by 5–10°C, with no internal construction or operational disruption.
Does reflective roof coating really work for Indian factories?
Yes — reflective roof coating works measurably in Indian factory conditions. Floorzy demonstrates this before every Heat Lock installation: treated and untreated metal sheet samples are measured under direct sunlight with an infrared thermometer. Customer-reported results across Karnataka factories consistently show 8–15°C interior temperature reduction during summer months.
How long does Heat Lock roof coating last on tin shed roofs in Karnataka?
Heat Lock roof coating on tin shed roofs in Karnataka delivers consistent solar reflective performance for 5–7 years before a maintenance top coat is recommended. The maintenance coat is a simple, fast operation significantly less expensive than the original installation. With regular maintenance coats, the Heat Lock system provides indefinite protection for tin shed roofs.
What is the best roof coating for asbestos cement roof in Bangalore?
For asbestos cement roofing in Bangalore, Floorzy's Heat Lock system by DUSH Italy is the recommended coating. Fully compatible with asbestos cement substrates, it seals the surface, provides solar reflective benefit to reduce indoor heat, and waterproofs hairline cracks and weathered joints — without any removal or disturbance of existing asbestos cement sheets.
