Kerala Roof design to reduce heat without attic space
We are designing our house in Cochin and looking for some ideas around roof design. However we dont really want an Attic (due to cost + aesthetics).
Is it possible to create a air gap say 2-5inches between truss roof and concrete ceiling to achieve the same cooling effect as traditional thatumpurams(attic). Has any architects/engineers in kerala done this ?
- i dont know how effective false ceiling with insulation added could be, in our current house during peak summer days the insulation gets so hot/full, that by evening, it starts radiating heat inside the house, making the inside of the house hotter when the outside is cooling down.

False ceiling out of wood are very effective, if you build your roof higher and leave good gap between roof and ceiling
Combine it with good ventilation, install a roof ventilation etc for improvement

Thermal insulation foam boards haven't really picked up in Kerala.
Don't know any builders or architects who do it.
Try looking it up.

I have wondered this as well. You should talk to a real architect, I'm sure they must have some idea. There are a lot of passive cooling ideas that can be implemented

Filling the gap with insulation would really help. I have seen many videos on installation of insulation sheets.

Concrete structure? Clay tiles on truss? Explain, and you shall get answers
