No C24 timber in the construction

[Bananaosten]

Hello, I recently went to look at a house. Everything actually looks good; it's an old house that has undergone a total renovation.

However, it turned out that the roof trusses are not made of k24 marked timber. What should a buyer do? It’s interesting to know, what does the seller do?

If wood free from knots has been used, you have the same strength. Then maybe the roof truss is oversized.

How do I find out if the roof truss is over-dimensioned? I know that the dimensions of the beams are 220.45,

It should be in the timber guide if I'm not mistaken about the requirements for the different wood classes, check there, go up and inspect the roof trusses so you can classify them adequately.

If it is an old house, the roof trusses are obviously holding.

Roof trusses can be dimensioned correctly whether you use C24 or C14 graded timber, the difference is that you need to use larger dimensions if you use C14 timber than C24...

-Are there no construction drawings of the house?

-If you want to be really sure, measure the trusses' geometry, dimensions, span, and any load-bearing central walls or similar. Then go to a truss designer and ask him to check these.
