Curious but had to ask - Fiberglass Exterior Roof

[Classic Finn]

Those of you that have skinned your tear with the White Fiberglass - (On the Roof - Exterior.. how thick of ply did you use underneath?

I was thinking of 3mm since my Fiberglass Sheeting is 1.8 mm in thickness but actually does it need to be at that thickness? I do have the 1.5 mm ply sheeting left...





Maybe Paul from Down Under can chime in...

can you use hi dent foam underneath. that way you have more insulation for the weight

Good evening Glassice... Its a pleasure to hear from you..

Can you tell me what you mean by high dent foam please? I have 50mm
foam on the ceiling at present..is that enough?

I just thought it would be sort of a waste to put another layer of ply underneath unless its for strength purposes

Best regards to You.

I use the brown ins 1 " on are trailers the glass is to stop you from putting your finger through the foam If you can glue the 2 together it supper strong like some jet fighters are made that way .I see you did a great job fixing your fender when we do the round parts cut in to 2" strips lay in and fell in with 2 part foam( it's cheep that way) can foam will work but not as strong

Ok now I understand what you mean...gotcha..glue some foam on the underneath for extra strength..

I did do some repair on the fender a few days ago.. its looking better than it did.. 1st time playing with small amounts of fiberglass ever..

Thank You Glassice
