What is Cellular Vinyl?

Genesis all-cellular window system components (the frame, sash and sill) are made from a material called cellular vinyl.

Cellular vinyl is manufactured by combining 100 per cent PVC vinyl with an agent to create a closed cell foam structure, which traps micro-pockets of air and enhances the thermal performance of the material.

Since there isn’t a grain to all-cellular vinyl, it won’t split, crack or warp. Unlike wood, the base formulation is not absorbent so it won’t take on moisture – resulting in a product that is not subject to rot, mold, mildew, insect infestation, flaking or peeling when exposed to high moisture conditions.

The exterior is wrapped with a solid vinyl cap that provides a smooth, hard surface. This provides additional rigidity and strength and allows a flawless finished surface that is practically maintenance free.

What is Celluar?

The first choice for building professionals and homeowners alike.

PVC—or vinyl—has long been recognized as one of the most durable and installer-friendly building materials on the market, and cellular vinyl is no exception.

Cellular vinyl products have been available as early as 1970, though recent advances in manufacturing techniques and processing aids have made it increasingly popular with homeowners and building professionals.

Homeowners love cellular vinyl because it is virtually maintenance free and it complements all exterior cladding materials, including vinyl, wood, stucco, fiber cement and brick.

Installers prefer cellular vinyl because it is lightweight, durable and can be installed using ordinary woodworking tools.

Architects and builders specify cellular vinyl for their projects because it can be milled, routed and heat formed into curved shapes for architectural windows and custom designs.

Like wood…only better.

All-cellular vinyl windows by Royal Building Products are superior to wood products in many applications.

Cellular vinyl products handle in the same way as wood with the added bonus of being maintenance free and rot resistant. Cellular vinyl outperforms pine in impact strength, water absorption and resistance to burning. As wood prices escalate and pressures mount to preserve forests, cellular vinyl becomes a cost effective and ecologically sound alternative.
