Foam plastic

Hello!

I'm considering using 50 mm cellplast as a wind barrier instead of asphalt board behind the panel. Does anyone have any experience with this?

From one of the manufacturers (sundolitt) comes this text:
"Application area:
The facade board is used as external thermal insulation and wind protection on the frame structure in small houses, multi-family houses, office buildings, etc. It can also be used as external additional insulation for all types of wall constructions.

The facade board has tongue and groove."

Hello!

I'm considering using 50 mm cellplast as a windbreak inside the panel instead of installing asphalt board. Does anyone have any experience with this?

It is a very good solution, both in terms of moisture and energy performance, and I've only heard good things about this solution.

Best regards

Yes, but what I'm wondering a bit about is if it becomes too tight, meaning that the moisture that is inside between the plastic on the inside and the foam plastic on the outside can't go anywhere. Or is it the case that the foam plastic breathes to some extent?

You're right to think that! Rest assured, the foam plastic is tight, yet vapor-permeable. It won't be too tight.

I wonder if this is possible without the risk of moisture damage:

1. panel (outer wall)
2. wind barrier
3. cell plastic
4. asphalt board

No air gap can fit, I want to have asphalt board as an inner wall because I had some left over. Thankful for answers.
