Would be interested to hear about that.

What would you like to know?

But then they are selling the stuff. 😀

I've always found that they give the correct advice and don't  sell for the sake of it.

That's  good business too as they started with just the one passionate inventor: was it 25 years ago?

Interesting reading everyone’s replies.

BCO for me has stated it’s required and sent me a letter to that effect.

Hopefully the picture uploads. My issue is I have a tiny amount of room for batten / counter batten above the window, so I have no idea how I am going to run an intumescent strip along the top with  ventilation mesh all while leaving a gap to the soffit.

 

I’ll see if I can find this NHBC guide, but as it stands agree with others that none of the guides are clear cut

Not sure if there’s anything out of shot that we can’t see, but I’d say there’s no point putting intumescent strip above that window. Just use treated timber that’s 38mm or deeper to close it off, don’t think there’s anything worth ventilating there.

@Owain1602 >>> What are you going to do at the heads of the windows?

 

We used thin stainless strip as per an earlier ‘ub discussion. Quite a bit of work, but done now. Much cheaper than intumescent of course and seems to me anything fireproof will work (maybe not in the regs though) as you don’t need the expandability of intumescent.

Does that mean you aren’t ventilating the cavity above the window, nor allowing moisture that sits above the windows to make its way out?
