About This Windows, Doors & Water Management Guide
A high-performance window or door depends on more than the product itself. The rough opening, sill pan, flashing sequence, drainage path and perimeter air seal all have to work together. A correctly rated product can still underperform when installation details are incorrect or incomplete.
Windows and doors are among the most important openings in a home's building envelope. Selecting the right product is only the first step; careful preparation, installation and verification are what allow the opening to perform as intended.
