Outdoor gypsum vs West Coast board?

[Nygge72]

Hello, if you're going to build new today, what is preferred to clad the house with under panel? I'm thinking if you build it yourself, put up the framework, then clad the house in some weatherproof material, such as Utegip, or alternatively Västkustskiva.

What are the advantages/disadvantages between the two materials?

I'm thinking of building it yourself so you erect the framework, then completely clad the house in this material, and then cut out for windows/doors when it's time at each spot, so you can be as efficient as possible to start weatherproofing the house.

What are your thoughts, experiences on this?

It's partly a matter of taste and preference.

I like the outdoor plasterboard, have no experience with the west coast board.

Not easy to compare as they have different purposes to a large extent.
Insulation versus panel action, for example.
Small houses are often built with a climate panel so you avoid a heavy frame.
Installation and subsequent work are easier with exterior gypsum.

If you want a low price and a classic trouble-free mtrl, I consider Örnpapp superior. If you want something even easier to handle, Windy is much more convenient than utegips.

We used utegips when construction was ongoing during winter.

I can imagine that's the case, but since I plan to do most of it myself, I want it to be as weatherproof as possible from the start, so using some sheet material feels like fewer steps. But perhaps I'm thinking wrong. Or do you put Windy directly on the frame, then insulate from the inside so that the insulation rests against it?

Sure, if you can get help to hold the roll, a full-story Windy is probably the quickest and easiest way to make it weatherproof.

GNU exterior gypsum is heavy and cumbersome to carry and handle.

If you're going for an external cross battening, you should insulate that layer from the outside regardless of whether you're using Windy, Örnpapp, asfaboard, or GNU.

As I see it, there are two different boards with their different functions..
GNU plasterboard provides a weatherproof house but also stabilizes the frame.
The Västkust board is mainly used for its thermal bridge-breaking properties but does not provide stability to the frame..
Most often when we have installed Västkust boards, it is on some type of other board that is attached to the frame, e.g., Vindskyddsskiva cemberit or equivalent..

Do you @Rejäl consider GNU advantageous instead of installing Windy externally and an internal cross-braced installation layer with board material?

 

[Plupp 405730]

Do you consider GNU to be advantageous instead of placing Windy outside and an internal cross-barred installation layer with board material?

No, I'm not a proponent of GNU. But I believe one should have some board that stabilizes the house, especially when building a villa.

 

[fribygg]

No, I am not an advocate of GNU. But I believe that one should have some panel that stabilizes the house, especially if you are building a villa.

Certainly, most people would put a horizontal installation layer inside and double panels on it.

 

[Nygge72]

Sure, most people probably install a horizontal installation layer inside and double boards on that.

Yeah, good g will probably stabilize with OSB/gypsum from the inside otherwise I think

 

[Plupp 405730]

Of course, most people install a horizontal installation layer inside and double boards on it.

Yes, but it's late in the build before it's in place, the house is exposed to great forces already during, for example, the boarding when a couple of quite heavy and round guys walk on the roof😊 as well as weather and wind..
We put up a board on the outside of the frame before we install the roof trusses and it functions as both frame stabilization and weather protection..
But sure, as simply as possible, a good windbreaker is sufficient..

Yes, but it's late in the construction before it is in place, the house is exposed to great forces already during, for example, boarding when a couple of so-so and somewhat round guys are walking on the roof 😊 and weather and wind..
A sheet on the outside of the framework we put up before we install the roof trusses and it acts as frame stabilization and weather protection..
But sure, as simple as possible, a good wind barrier is sufficient..

For me, it has been faster and cheaper to ensure stability with well-tensioned perforated strips before Örnpappen or Windy, GNU might be durable if the framework is supposed to stand without a facade for a longer time but it is heavy and time-consuming and quite a bit more expensive.
