I will have egress windows cut into my cement basement walls for a major remodel, will use a standard 48" x 48" slider or casement.
Two contractors told me they simply frame the new concrete opening with 2 inch "green pressure treated lumber" and then set the window. There may be a bit more lumber for the header "to align with basement ceiling" or structural needs, but other than that all there will be is a single board between the cement and window frame.
(FYI... my city does require an engineers document specifying any structural header needs in order for the city to give me a permit to cut two big holds in my basement wall. So that bit will be taken care of.)
But just a single 2" board sounds too fast and easy. Is there a "proper" way or am I just use to doing things the hard way?
