Exterior wall construction? Garage

[Suhagg]

More questions.

Is asfaboard really necessary in building a garage? I want to build something well-constructed and good but need to weigh some pros and cons of everything and learn why it's built in a certain way
If I choose asfaboard, should I seal the seams in some way too?

Seems like many just go with wind barrier paper. What attributes and advantages does asfaboard offer?
It costs quite a bit too, so I'm trying to evaluate if it's justified.

You can choose a bit of whatever you like, vindpapp, asfaboard, utegips vindväv ...

I used vindväv on the small cabin and house (very quick and easy) and asfaboard on the garage. The garage stood with asfaboard and nail battens for a winter, so it almost felt like walls. I also had some tools in there. I haven't done anything about the seams between the asfaboard panels, but all the seams are on studs and I've stapled quite closely, at least every 10 cm.

I suggest asfaboard or utegips for you as it will become the de facto interior of your carport. Vindväv is more easily damaged, not to mention old vindpapp. Vindväv is also not as nice as a visible interior; asfa or gips is much tidier.

Thanks. I guess the price shoots up quite a bit compared to plastic.
You don't happen to have a figure on how this is priced?

Unfortunately, I don't have a price on it, I haven't used it myself but have only read about those who have. Give your builder's merchant a call and check with them if they can get it or have it in their range. They should also be able to give a price, but sure, I think it's more expensive but as I said, I'm not sure.

You can choose a little what you want, windproof screen, asfaboard, outdoor gypsum wind barrier ...

I put a wind barrier on the shed and the house (very quick and easy) and asfaboard on the garage.
The garage stood with asfaboard and nailed battens for a winter, so it almost felt like walls. I also had some tools in there.
I haven't done anything about the joints between the asfaboard panels, but all the joints are on the studs and I've stapled quite tightly, at least every 10 cm.

I suggest asfaboard or outdoor gypsum for you because it becomes the de facto inside of your carport.
Wind barriers are more easily damaged, not to mention old windproof paper.
Wind barriers are not as attractive as a visible insider either, in that case, asfa or gypsum is much tidier.

Thanks. I'll include asfaboard in the quote. Did a quick calculation, and it's max 8k or so for what I need, so it's not a huge amount for a project of this size. Also gives a nicer inside to the carport as you say.

Unfortunately, I don't have a price for it. I haven't used it myself, just read about those who've used it. Call your construction supplier and check with them if they can order it or have it in their range. They should be able to give a price, but yeah, I think it might be more expensive, but again, I'm not sure.

I'll look into it later. But I'm not too keen on being the first with "new technology." If they've been building with plastic for 25 years and it's worked well, then I'll stick with that.

 

[Ola78]

The technology is not completely new, the first time I heard about it was about 5 years ago. However, I have not looked into how well it works.

 

[Suhagg]

Now we are starting to consider more expensive materials for the roof as well
I was thinking of oil-resistant board and roof tiles, but råspåntluckor were really affordable.

The more people you talk to, the more opinions

The carpenter says
Asfaboard, what kind of old carpenter guy recommends that?

In that case he says outdoor gypsum, but that's not what he recommends, he says go with wind barrier.

We'll see where it ends.

Wind barrier fabric is also good. Quick, smooth, and cheap. Probably the best performance, i.e., the best ratio of wind resistance to diffusion openness.

However, then you have the wind barrier fabric visible on the inside of the carport, which isn't particularly bad in any way, but if it were asphalt board or outdoor gypsum panels instead, the visual impression of the carport section would be enhanced.

Outdoor gypsum is quite heavy to work with, but it has some significant advantages, the biggest being the reinforcement of the framework you get. Even outdoor gypsum provides you with a relatively attractive interior in the carport section.

I can't designate any of the alternatives as the absolute best that outshines the others. The pros and cons are roughly of the same magnitude. It's just old-fashioned tarred windproof paper that I think doesn't qualify at all, as the wind barrier fabric has all its advantages and more.

You can have windbreaker inside the garage and asfaboard or outdoor gypsum in the carport section otherwise...
