Rigid Foam Insulation (IPN or PUF boards) combined with Brick-Bat Coba or tiles is the most effective terrace heat proofing solution. This multi-layer technology forms a strong thermal barrier, trapping heat before it gets to the ceiling and lowering indoor temperatures by up to 15°C to 20°C. Unlike other solutions that only reflect sunlight, this solution insulates and safeguards the roof, making it perfect for long-term heat reduction.
Why Does Rigid Foam Insulation with Brick-Bat Coba Work Best?
This method includes coating the terrace slab with PUF or IPN insulation boards, then applying a waterproof layer and a protective top layer of Brick-Bat Coba or broken china mosaic.
The insulation prevents heat transfer, while the top layer protects the roof from direct sunshine.
It is ideally suited for top-floor flats and independent houses undergoing significant terrace renovations.
The average installation cost ranges from Rs. 180 to Rs. 320 per square foot.
Are High-SRI Cool Roof Tiles a Good Alternative?
Yes. High-SRI cool roof tiles made from vitrified or ceramic material can lower roof surface temperature by up to 15°C.
They resemble regular floor tiles and provide a durable, aesthetic finish.
This option suits homeowners seeking cooling efficiency and longevity.
Their average cost ranges from Rs. 110 to Rs. 180 per sq. ft.
Which Heat Proofing Method is Best for Existing Roofs?
High-SRI cool roof paints are a great option for a low-cost upgrade that does not require structural work. These acrylic coatings with infrared-reflective ceramic pigments can reduce indoor temperatures by 6°C to 10°C while also offering waterproofing. Popular alternatives include LuminX Cool Roof Coating and Asian Paints SmartCare, with pricing ranging from Rs. 40 to Rs. 85 per sq. ft.
The most effective heat-proofing methods depend on whether the goal is a structural renovation or a surface-level application. I hope you understand which terrace heat proofing method provides the maximum temperature reduction.
