What to use instead of plastic in the ceiling?

[Schlbuditz]

Hello!

I'm insulating a garage that will mostly remain cold but will be heated occasionally, and I've therefore decided not to use plastic on the walls and ceiling. What I wonder is if anyone has a tip on what I can use for the ceiling instead? I want something that can hold the insulation above the rafters. Or can I use plastic on the ceiling even though I don't have it on the walls?

In the walls, I've used wind barrier instead of plastic, and then there's OSB+drywall on top of that, so the walls will probably be quite tight anyway. The problem with the wind barrier is that it easily tears, so I'd like a slightly more stretchable material for the ceiling.

are you planning to have any other covering on the ceiling

I drive,

Ceiling: plasterboard, sparse, plastic, insulation, oilboard air gap, roof

Wall: plasterboard, insulation, outdoor plasterboard, air gap, panel

I think it works!

 

[Schlbuditz]

Yes, either ceiling gypsum board or some wood paneling on the ceiling. However, I don't want to place the insulation directly against the ceiling covering.

torparkalle: Have you been driving like that for a long time? How is your building heated?

It feels like my solution will be very similar to yours if I plasticize the roof.

no insulation directly against plaster/panel

The problem with the wind barrier paper is that it easily tears, so I would like to have a slightly more flexible material in the roof.

Do you mean in the wall now? As I said, I have no plastic there.

That might be something! Do you know if it is "tough" like regular age-resistant plastic, or if it is a bit harder?

 

[injonil]

It's tough! The material doesn't resemble age-resistant plastic at all, but it's tough nevertheless!

In the ceiling, though. And pkast doesn't break when you set sparse

Have recently erected the walls, has three rooms. The garage section gets 10, the hobby section 20, and the pump room 5 degrees! Will heat waterborne but electric initially! Have read many threads about plastic here and there, ended up with no plastic in the wall!
