Overdeck insulation
Roof insulation is equally as important as the external roofing material. It plays a vital role in enhancing the durability and service life of the roofing system and has been practiced for many years. Although insulation technologies have evolved over time, their primary purpose remains unchanged — to retain heat when required and block unwanted heat from entering.
Installing insulation over the roof deck of a building delivers long-term cost savings. By regulating indoor temperatures, insulation reduces dependence on heating and cooling systems. Lower energy consumption not only decreases operating expenses but also supports environmental sustainability by reducing the building’s overall carbon footprint.
Areas of Application
- Above metal roofing sheets with proper waterproofing treatment
- Over RCC roof slabs with suitable waterproofing protection
Roof Insulation Materials
- Fiberglass blankets and boards
- Rockwool rolls for building insulation
- Thermocol (EPS) insulation
- XLPE insulation sheets
- PUF (polyurethane foam) insulation
- Rockwool slab insulation
- Thermal isolation boards
- Nitrile rubber insulation
Advantages of Roof Insulation
- Energy Efficiency: Thermal insulation limits heat transfer between indoor and outdoor environments, reducing the energy required to maintain comfortable room temperatures.
- RYear-Round Comfort: By minimizing heat gain and loss, insulated spaces stay cooler in summer and warmer in winter compared to external conditions.
- Reduced Thermal Stress: Insulation lowers temperature fluctuations on roof decks, helping prevent cracks and structural stress caused by thermal expansion and contraction.
- Lightweight System: Over-deck insulation materials are significantly lighter than traditional brickbat coba or concrete layers, decreasing dead load on the roof slab.
- Eco-Friendly & Non-Toxic: Insulation materials are safe, non-hazardous, and environmentally responsible.
- Lower Operating Costs: Energy savings lead to reduced air-conditioning running expenses and potential downsizing of HVAC equipment capacity.
- No Heat Absorption: Insulated roofs minimize heat buildup and subsequent heat radiation into interior spaces.
