So it's not needed for building regs but as I have some celotex left it won't hurt to use it?

Hi I've just had a new flat roof installed which is a 3 layer felt system with a warm & cold deck. They have installed new joists, new boards and done the hole roof new. Joists are 8x2. I've noticed there are no cross noggins anywhere. Are they needed for building regs? Will the...

I'm sorry but I can't make sense of these posts? Use the celotex or a block or neither & just leave as is?

I've just had a warm deck put on my new extension. Within the walls is 100mm dritherm & celotex is on the roof. Before the inspector comes I'm wondering if the gaps between the joist, that sit on the wall, need filling. I was gonna cut celotex and push in the gaps. Is this sufficient...

Yes, thats what the roofer said today. I'm happy to replace it but is it possible to drop it down it between the joists? That will mean a section of it boxed in at ceiling level in the kitchen?

I am having a wall removed, due to a kitchen extension, and a flat roof fitted on the extension. The soil pipe from the toilet runs in the way of where the steel will be going and the flat roof joists. How can I get the soil pipe down through the steel, and the joists, without the fall being...

That's a very similar circumstance to this. Thanks for your advice mate.
