The Science of Window Performance & Care in California
Window efficiency and thermal envelope integrity play an important role in residential heating and cooling energy loss, indoor comfort, and moisture management.
Poorly sealed window perimeters can allow air and moisture movement around rough openings. When interior surfaces fall below the local dew point, condensation may occur. Proper flashing, air sealing, drainage, and installation details help reduce moisture risk.
Low-E coatings, insulated glass, and gas-filled cavities can improve thermal performance compared with basic single glazing. Actual performance depends on the window assembly, product rating, installation quality, orientation, climate, and existing home conditions.
