Composite Siding

Ascend Siding
A first-of-its-kind solution, ASCEND® composite siding combines beauty, performance and easy installation for the best overall value on the market.

Tall exposures and the deeply grained look of real wood, it captures the high-end aesthetics today’s homeowners demand.

Patented (GP)2 technology: the world’s first composite cladding engineered with a combination of Glass-Reinforced Polymer and Graphite-Infused Polystyrene. This patented (GP)2 technology was developed to achieve superior performance in tests for wind load and impact resistance, workability and flame/smoke spread. (Class A Fire Rating)

Installation is quicker and easier than that of fiber cement, engineered wood and other composite panels and can often be installed by fewer laborers working at a time.

Requires minimal maintenance, day after day, year after year. Keeps that “just-installed” look.

Award Winner: The National Association of Home Builders (NAHB) named ASCEND® “Most Innovative Building Material” in the Best of IBSx™ Awards 2021
