CompositWood Windows                         

Offering both the benefits of a fabricated exterior and the beauty of a natural wood interior, CompositWood windows from National Vinyl are the perfect choice for homeowners looking to marry aesthetic desires with strength and durability.

Our CompositWood windows offer the best qualities of both wood and vinyl windows - natural wood beauty on the interior and insect, moisture and weather resistant vinyl on the exterior. CompositWood is an engineered material that provides superior performance on many levels. Because of its unique solid

core structure encapsulated with a rigid, pre-finished SuperCap surface, it has the lowest thermal conductivity compared to other typical window frame materials.

CompositWood is a proprietary blend of specialty PVC polymer and acrylic resins that can be chemically or fusion welded to create superior, weather-proof joints - unlike fiberglass, aluminum, or wood that require mechanical fastening and sealants that can fail over time. And because of its chemical makeup, the material is readibly recyclable for future use.

CompositWood windows far exceed Energy Star Criteria and are AAMA and NFRC certified to further meet or exceed industry structural and energy efficiency standards.
