I will have egress windows cut into my concrete basement walls (9" thick), will use standard 48" x 48" slider or casement windows.
Tow contractors told me they simply frame the freshly cut concrete with 2 inch "green pressure treated lumber" and then set the window. (They will do more for a header if needed for space alignment or structural needs.)
But just a singe 2" board sound too fast and easy. Is there a "proper" way or am I must use to doing things the hard way?
