I am relocating 2 patio doors in an extension. I know how to get the units out and fit them in the new openings but lately i've noticed that double glazing fitters are using crazy foam in all the gaps around the units. Is the foam squirted in after the units are secured if not can someone enlighten ...
[quote="TJ"]Does anyone know where I can obtain brown mineral felt from. I know roofing shingles come in different colours but the only coloured felts seem to be grey and green. Any advice gratefully received.[Try either Icopal or Chesterfelt/quote]
