Heat Reduction & Energy
Roof insulation for Indian homes — keep summer heat out
Over-deck insulation, insulated tiles or under-deck systems that slow heat flow through your roof, chosen for your structure.
A reflective coating bounces sunlight away. Insulation goes further: it slows down whatever heat still reaches the roof from flowing into your rooms.
RennovEN recommends the right insulation for your roof — over the slab with protective tiles, insulated terrace tiles, or under the slab where the terrace is in use.
Signs you need this
- Reflective coating alone hasn’t been enough
- You are redoing terrace flooring anyway
- You live in a very hot city
- You want lower cooling bills long term
The RennovEN promise
- 10-year warranty on all works
- Itemised pricing, approved before work begins
- One accountable team across every trade
- Residential specialists — homes only
Diagnosis
Why it happens
Conduction through concrete
Concrete conducts heat well, so a bare slab passes heat straight into rooms.
Long hot seasons
In many Indian cities, roofs get months of intense sun every year.
Night-time radiation
A heated slab keeps radiating warmth after sunset.
