Would this work for underfloor insulation using Rockwool

Asked by: quinner83
I used it for that purpose. It should let the air flow through the insulation but keep the moisture out. It is really easy to use as it is strong, doesn't tear, and you can pull it tight and staple.

I have a fiberglass flat roof with 2 roof lanterns and would like to know if I can use this between the insulation and plasterboard to prevent condensation. Thank you

Asked by: Surbjit
No, I would use a polythene vapour barrier that (almost) entirely blocks vapour. You do not typically want to let warm moist air into a flat roof structure assuming it is timber as there is no way for it to get out the top through the fiberglass, and there is a risk the moisture will condense somewhere within the roof structure. I would then aim to ventilate the room to let the moisture laden air out by other means.

will this be ok to line the outside of a shed

Hi will this be ok to line the outside of a shed before putting on cladding
Asked by: scottydog14
Vent3 Light is designed as a secondary barrier to wind driven rain and snow, it should not be considered a primary waterproofing layer.

Is this material plastic or cloth based?

Would be useful to know whether staple gun can be used to apply it?
Asked by: DMC180
It's paper like cloth like material. Staple fun is all you need. Make sure you're using galvanised staples or similar
