PVC Window Components

An Alternative to Wood Frame and Sash

About Cellular Window Profiles

Cellular frame and sash profiles are made out of PVC material.  It can be used as a material substitute for wood and composite double hung windows. Our traditional wood-look cellular window components are extruded using high-quality exterior grade cellular PVC material. The final product is durable, low-maintenance, and provides long-lasting beauty. We developed cellular profiles because we wanted an energy-efficient, pre-finished, non-rot replacement for wooden sash and frames in double hung windows.

Why Choose Cellular Sash for Double-Hung windows?

Consumers are increasingly more focused on energy-efficient windows for a variety of reasons. Often consumers want more energy-efficient windows in order to save money on their heating and cooling bills. Consumers also want windows that are resistant to damage caused by weather such as heat, rain, hail, snow, and insects. Often consumers want wooden windows, but dislike the maintenance required to maintain them. Wooden sash is typically prone to rot, and is less mold and mildew resistant. To keep wooden sash in shape, it is necessary to perform regular maintenance. This required maintenance leads to increased costs and more problems for consumers.

Our cellular sash provides the ideal solution for your customers. Our exterior-grade cellular PVC profiles match milled wood window components. Not only does our cellular sash make double hung windows more energy-efficient, it also provides greater insulation and protection against heat, hail, snow, and rain. Our cellular sash is mildew and mold resistant, as well as insect-resistant, including termites. It is complementary to a variety of designs, and provides a wood-look finish.
