Construction/House AMA about angles on interior walls?

[ramini]

I've tried searching a bit about this...

What does Hus-AMA specify for tolerances for interior walls? Let's say a wall is to be built at right angles to another - how many degrees can the tolerance be?

From AMA Hus 11:

TOLERANCES
Walls made of panels and wooden studs or wood-based studs should meet the requirements according to Table 43.CB/HSD-1.
The requirements also apply to the frameworks.
Table 43.CB/HSD-1. Walls made of panels and wooden studs or wood-based studs


This applies to interior walls, however, not structural interior walls (load-bearing).

You can take the opportunity to recommend Besiktningsmannaboken, where most tolerances and standards can be found. http://www.gar-bo.se/besiktning/besiktningsmannaboken-2013

Thank you for this. I interpret it as the measurement between two inner walls should not differ more than 25mm anywhere. However, it doesn't say much about whether the wall is perpendicular to another wall or not. What are the standards there?

This is what the measurement definition says:

No. 25. Distance between adjacent columns, beams, walls, masonry, or
other supporting structures
The requirement applies to any position of the measuring points, but perpendicular to each other and
preferably at the end or middle of the component. Can also be calculated from position control.



By adjacent wall, they mean the wall that runs parallel to the wall being measured. +-25mm is therefore the tolerance for what you call perpendicularity.
