Hi.
Can someone tell me the correct procedure for closing window and door cavities.
I know you can buy cavity closers specifically for this, but the BCO has said that he is happy for us to just close the cavity with the 60mm of insulation that we were using for the wall cavity and use some DPC for the external wall.
Sounds a bit time consuming, so I may just buy the proper product, but is what he is saying OK to do.
Also what is the best way to close the cavity on the bottom of the door opening. One of the tradesmen said that he just fills it with concrete, but I can't see that being correct as you're breaching the cavity.
Is a cavity closer sufficient. I don't know if it is strong enough to support people walking over it.
Thanks.
