Intergrated Water Ingress Prevention
Window corners are generally prone to rainwater leakage, and secondary waterproofing (sheets and tape) may not be enough to stop the water. Since WEATHERTIGHT for Windows has a back dam, even if water enters the corner, it is discharged outside the secondary waterproofing.
Variety of options to Match Different Frame Sizes
With the advancement of high‑insulation and energy‑efficient housing, window systems have become higher in performance, increasing both frame thickness and engagement depth.
WEATHERTIGHT for Windows offers 3 width options to suit different frame sizes.
