ah i get it, i will do a strip, 200mm seems a little small though doesn’t it? Also what are your thoughts about the rockwool question? Thanks

what do you mean by “either full fill or 200mm strip if you don’t mind laying blocks in a trench”. I’m thinking of having 100mm full fill rockwool for my cavity, where do i start this below above or on the dpc. Thanks

Hi, how deep would I need to did for my footing and how thick and wide does the concrete footing need to be. It will be a concrete block double skin wall about 2.2m high. I’m thinking to have the footing 450mm wide. Thanks.

as electrified said, i’m doing similar to this and need to know what cavity size and insulation to put in this, thanks.

Hi is a 50mm cavity ok to have and can you fullfill celotex board? Or would it just be better to have a 100mm cavity? Thanks

This is what I will do. 100mm cavity with 100mm or 50mm rock wool batts. Which would you recommend?

If i need to do a 100mm cavity i will it’s the right way to do things, what I do not want however is damp from bridging the cavity, so i need to know if the full fill will cause damp? Also say I didn’t put insulation in the wall and left it at a 50mm cavity, what would happen other than heat...

Ok ok. Cavity wall with block on the outside and inside. Wall is being rendered on the outside. Now the main concern here is cold bridging right? When warm air hits cold and condensates and causes damp. What cavity would you recommend and what insulation? I’m guessing you have to have insulation...

:D

i thought 50mm cavities were the nominal size for a cavity and is allowedo_O, doesn’t it say in nhbc?

Sorry I mean building one, are you saying i can put rock wool batts inside my walls without bridging the cavity and causing damp?

Hi, I have a brick cavity wall, the cavity is 55mm and was wondering what type of insulation I can use that won’t bridge the cavity and cause problems later on. To my understanding celotex brand insulation shouldn’t touch both leaves of wall. I have seen wool insulation being used, that fill...

serve notice to neighbour?

I’ll have you know I have many trays in my house.
