What material costs less when it comes to PTFE, ETFE, glass and fibre glass.

Question

as a building material which is the most cost effective?

Answer 1

Stuff has different uses.Cost  is irrelevant, cuz u cant use the wrong material, or it will cost u more in the long run.

I mean, you wouldn't use fiberglass where you needed glass, right? And are u refering to fiberglass panels/sheets, or fiberglass insulation?

And glass...there's like fifty different kinds.
