A diffusion-open windproof plastic film on the inside

[Ribiku]

Hello!

I'm new here in the forum, but I read a lot here, and sorry, my Swedish isn't the best.

I have 2 rolls of diffusion-open wind-protective plastic foil left, and I want to prevent air/wind from entering the house. We are renovating a small house (55m²), and the wall is:

| 15mm raw wood | 100mm sawdust | 20mm old facade | 50mm mineral insulation | windproof paper | facade |

I want to apply now on the raw wood:
| diffusion-open wind-protective plastic foil | 20mm air | 20mm beadboard |

I have replaced all the windows with triple-glazed ones. Do you think it works well with diffusion-open wind-protective plastic foil on the inside?

Thanks in advance for the answers!

What is the material called that is "diffusion-open windproof plastic film"? Spontaneously, I think the material on the inside should be more diffusion-tight.

What is the name of the material that is "breathable wind-protective plastic film"? Spontaneously, I think the material on the inside should be more diffusion-tight.

Hi Andersson,

thank you for your response. That is correct if you're building new, but now there is no barrier and the insulation is minimal. But I don't know if it will work so that the air doesn't condense in the wall if you build it the way I mean.

I don't know if I can show the product here directly, but if you search for Vindskyddsfolie on Google, you can find the product directly.

Thanks! Best regards,

Mario

A rule of thumb is that the differential lock/limited-slip differential on the inside should be at least 5 times tighter than the one on the outside. So the question is whether the windproofing membrane has 5 times higher vapor resistance than the wind barrier paper?

A general rule of thumb is that the inner differential lock/differential brake should be at least 5 times tighter than the outer one.

I have seen what happens when this is violated.
A guy built his house and tried to make it "eco-friendly."
"Vildmarkspanel" on the outside, air gap, exterior gypsum board, 145 mm cellulose insulation.
There wasn't supposed to be any plastic film. But he didn't manage to put up the inner panel...
After a year, he looked behind the cellulose insulation: The inside of the exterior gypsum board was spotty black with mold

Hello again,

thank you for all the answers! I better use an age-resistant construction plastic, but then I need to cover the entire room, right? Floor and ceiling I mean? Or is it better to just cover the window frame, so no wind gets in there.

Thanks and best regards
