Planning Your Vinyl Windows and Patio Doors to Meet Building Codes
Well before the patio doors and windows arrive at the site for installation, planning and research should be done to choose a window or patio door that fits the situation. Check the local building department's requirements regarding egress, safety glass, and grade (structural integrity) before obtaining estimates and bids.
Retrofitting a house with high performance vinyl windows and patio doors can produce significant energy savings and improved comfort. However, when the right window is installed incorrectly or worse yet, when wrong window or patio door is installed incorrectly, energy savings will be few, structure and furnishings may be damaged, and the occupants' safety may be jeopardized. The energy retrofitter needs to understand more than U-factors and solar heat gain coefficients when choosing and installing a window.
