First time fitting these, but have done a few windows in the past.
They're 3.2m, 2 sashes and 1 door so hopefully fairly manageable. They run on a track at the bottom.
Instructions aren't great (I think intended for trade), they say place cill on brickwork and level, put frame on top, fix all round, square up etc.
I have a few questions:
do I bed the cill on silicone and screw to brickwork?
what size self tappers to fix frame to cill?
what fixings for sides and head? I prefer screws and plugs to hammer fixings as my bricks seem to crack if you just look at them, even if it means having the frame in and out, I can take my time with the hammer drill rather than the SDS, or is there a better way, maybe those self cutting screws? my main concern is the finish inside the frame, I presume you go through the thermal break, do you countersink it so it looks neat or fit caps? Head is a lintel and I generally drill an 8mm hole through steel, then masonry and use a normal plug and screw.
I have 20mm spare on the height, I'd like to pack it as high as possible so could I pack 15mm under and have a 5mm gap on top?
Thanks for any advice or suggestions.
