Which roof heat & water insulation material is recommended

I have found a large number of vendors on internet providing roof heat insulation products & services in lahore. But out of those the 3 known ones ( known to me ) are :
A. Diamond supplies jumbolon board and polyurethane spray.
B. Master chemicals offers p.U foam spray is called thermoshield
C. Industrial enterprise provides thermopore and also supply polyurethane foam.

Keeping in view lahore's extreme weather as well as substantial rainfall, which product would you recommend ; sheets or sprayed foam , please also guide me with reason of your choice, and then further which brand / vendor is trustworthy?

Thanks in advance.

I have done some study on all these three vendors and their products. My conclusion is to use Polystyrene sheets also called thermopore 2inch thickness. Master chemicals selling as extruded Polystyrene sheets.

Polyurethene spray is not recemmended bcoz life is not so much and also expensive.

Here is a lot of discussion on this topic already.

Jumbolon and PU Spray is expensive and result is same as thermopore sheets as we always used thermopore sheets in our projects which is recommended as their low cost and effect is almost same....

Do not need to go for expensive materials.

Anything need to know do not hesitate to contact us.
