i live in a tropical country and i need to insulate my roof to block off the heat from the sun...which insulation would best help me? aluminum foil with foam, real foil with foam or PE with foam? pls help...thank u so much!
Use HDPE foam (high density polyethylene) - possibly with a layer of aluminum foil sandwiched in between. It's also waterproof (polystyrene isn't).
Expanded polystyrene (EPS) comes in sheets and is very long lasting and safe to use - no fibers, no itchy skin, no breathing issues....this is also used to keep cold out as well as heat and is durable.
look into a product called "Snow Roof". You roll it on like paint and it will lower inside temp 10-20 degrees.
