Non-toxic OSB and chipboard wanted!

[Kalle_Kiander]

Planning to build a house and looking for non-toxic OSB to place behind drywall. Also non-toxic flooring chipboard for the attic space.

Grateful for tips!

Best regards, Kalle Kiander

Not well-informed about boards but råspånt works behind the gypsum, perhaps it's also suitable as flooring in an attic space.

What is the poison in common disks? It would be interesting to know.

 

[Kalle_Kiander]

The glue may contain both isocyanates and formaldehyde. Especially in chipboard flooring which has such a large amount of glue. The OSB only has a couple of percent of glue, but you want to be on the safe side.

You write can. How do you know then?

 

[Kalle_Kiander]

It often does, more or less, at least formaldehyde. It is reported in the building material declaration. This is how it might look for a chipboard from Moelven:

Almost everything in the construction industry that contains some form of binder/glue (especially glue, paint, and sealants) contains formaldehyde and many other goodies that continue to release into the air long after installation.

Glue, I don't even know if there's any non-toxic good alternative when talking about construction? It would probably be nails and screws in that case.

Middle child >> Raw paneling would have worked, but would like to find something cheaper.

That's why I'm trying to keep it down as much as possible. We are building, for example, with Kebony façade, wood that has been impregnated in an environmentally friendly way and is protected against rot for 30 years without maintenance.

There are really good – and bad indoor paints. Just check out this test: http://www.testfakta.se/sites/default/files/tittbild_grafik160218_0.pdf

I know there are manufacturers in Denmark that make formaldehyde-free OSB, I'm currently looking for a Swedish retailer.

Surely råspont should be an option if you're going to screw plasterboard over it? However, quite a lot of extra work

Interesting... It certainly feels safer, especially with små children, to choose good building materials. How about linoljefärg? Or äggoljetempra?
I'm working on a new kitchen in solid pine for the frames and everything, completely different smell compared to IKEA furniture and particle board stuff... However, I have no idea how much impact it has in the long run, the formaldehyde should fade over the years, right?

 

[Marcussjogren]

Linseed oil and egg oil tempera contain no toxins as long as you don't mix in turpentine. The advantage is that the turpentine leaves the paint incredibly quickly, though I do not know how long it might continue to leave the paint. However, it is not necessary either.

There are really good - and bad - paints for indoor use. Just check out this test: [link]

How do you impregnate the wood in an environmentally friendly way?

Plyfa should have less glue than spån?
