AquaForm offers sills for windows that allow water to drain to the outside of the building. This system sits at the bottom part of the window only and is designed to keep water and air from getting inside the building. Our sills are effective against wind-driven rain, window washing, melting ice or snow, and any form of precipitation.

AquaForm Produces Quality Products

A high-quality sill that’s been properly manufactured will reduce mold and mildew inside commercial buildings. Our .050 aluminum sills are made off the job site, saving you time and money on every project. With our prefabricated sills, you can reduce your construction time without sacrificing quality. All of our products are part of the Green Initiative and provide an energy-efficient solution for builders.
