February 11, 20206 yr I'm easily confused so forgive me. If you are building a timber frame property, with an external brick skin, i believe you have to account for the timber frame settling. Ie; brickwork gap to soffit, window head and sills etc. So say you build a timber frame, and instead of putting on a brick skin, you slap on some renderboard, and K-rend etc. If timber frame settles, why don't all the render boards buckle etc.... Just a thought.
February 12, 20206 yr Author Just read that thread, and i am none the wiser. From what i have seen, even if joint gaps are left, they end up getting filled with basecoat before the mesh is put on. One of the reasons i asked is that i saw that effect of a house at BRE in Watford. The one in the thread looks very bad. I feel for them. Imagine trying to sell the house with it looking like that. Just as bad is the fact that nobody seems to understand what has caused the problem. The gaps specified for brick outer on a timber frame are quite large, so the timber must move a lot.

February 12, 20206 yr Author Well if nobody realy knows the answer, i won't be going for renderboard over a timber frame then.
February 12, 20206 yr Not that I know anything about the subject but putting a rigid product on a timber frame does seem counter intuitive. The same reason I don’t like ridge tiles mortared on, timber moves, mortar does not .

I guess letting the timber frame settle before boarding or fitting windows etc would solve the problem. Wouldn't work for those wanting a quick build though. You could use engineered timber like I-beams which would move a lot less.

I have been using them on flat roofs for years.

To be honest, i just worry about re-sale, non standard construction etc.. It's funny, building control have always said to me, you don't see i beams used on domestic extensions. But they all like the fact that i had used them.

It's just classed as timber frame, whether it's 140mm timber studs or 300mm I-beams. I think having timber cladding on timber frame might affect re-sale more than the frame material itself.
