Fitting Wooden Windows Into Concrete Block Cavity Wall

Postby EdF » Mon May 05, 2008 4:50 pm

I'm about to fit new softwood DG window frames into the apertures in a new concrete block cavity wall. Should I put a DPM around them, and are there any good fixings out there? Last time I used those long stud fixings (long, nail-like, in a plastic sheath) they were swines to use, many getting stuck halfway in, even though I used the correct diameter drill and cleaned the holes out.. It's a while since I used them and there may be something better available now. Any advice appreciated..

My opinion is you need "Frame" fixings and as a back up filler foam then sealant not "hammerscrews" as you describe then it should be fine. I used to work for a fixings company in a previous life!
