Old building standards and materials

[mattias1343]

My house was built in 1964. Today I began tearing down the facade for replacement, but instead of 60cc it seems to be 120cc, but there are nails every 40cc. However, there seems to be support behind the panel at 120cc.

Was there, at that time, asphalt board with aluminum on one side then joined with a treetex via a 21x95 plank every 40cm? The boards seem to go all the way up to the roof.

I will have to set new battens and shim to make the wall straight. Should I stretch a plastic over the board or is it fine as it is? There will be an air gap of about 21mm between the horizontal single fascia panel and the board, the panel will be painted with Falu Vapen traditional paint.

Was there back then asphalt board with aluminum on one side that was then joined with a treetex via a 21x95 plank every 40cm? The boards seem to go all the way up to the roof.

I will need to install new battens and shim so the wall is straight. Should I stretch a plastic over the board or is it fine as it is? There will be an air gap of about 21mm between the horizontal single-fascia panel and the board, the panel will be painted in Falu Red.

You should certainly not put any plastic on the outside. Possibly a windbreak that is vapor permeable.

To be able to follow your reasoning, you need to be more precise both in the description (what is horizontal and what is vertical) and the measurements of the components involved. Remember that it was inch measurements that applied. I wonder if asfaboard existed in 1964? I have no memory of that. In any case, a better description is required for my part. You should definitely not have any plastic on the outside of the wall. There is no disadvantage with an air gap behind the panel, but it is not necessary when you use slamfärg.

Remember, it was inch measurements that were used. I'm wondering if asfaboard existed in 1964? I don't remember that. In any case, a better description is required for my understanding. You should absolutely not have any plastic on the outside of the wall. Having a ventilation gap behind the panel is not a disadvantage but is not necessary when you use slamfärg.

I am going to install horizontal paneling.

But what I'm wondering about is if there ever existed a ready-made panel module with asfaboard 120cm wide, with 3 pieces of 21x95 in between and innermost a treetex board. Take an asfaboard 120cm wide, place 3 pieces of 21x95 boards vertically with 40cc on it, then a treetex board, and nail this together and mount it vertically. This is what seems to be underneath the panel.

No, I have never heard of such ready-made modules. But it could be a typhuskonstruktion.

No, I've never heard of such ready-made modules. But it could be a model house construction.

Ok, it was the owner who built the house himself, it could be his own idea, which creates problems for me since I don't know where the rules are. I will lay battens again with 80cc and attach the battens to the 21x95 planks that are between the boards. I don't want to tear down the whole wall and start over.
