Introducing ASCEND® Composite Cladding by Alside, a first-of-its-kind solution that combines beauty, performance and easy installation for the best overall value on the market.

With tall exposures and the deeply grained look of real wood, ASCEND captures the high-end aesthetics today’s homeowners demand. But with ASCEND, installation is quicker and easier than that of fiber cement, engineered wood and other composite panels. In fact, ASCEND can often be installed by fewer laborers working at a time.

After it’s installed, ASCEND doesn’t just perform... it lasts. And lasts. And lasts. Keeping that “just-installed” look for as long as it’s up, ASCEND requires minimal maintenance, day after day, year after year.

ASCEND is a winner for homeowners, builders, remodelers and installers alike. In fact, ASCEND has been recognized by the National Association of Home Builders (NAHB) as "Most Innovative Building Material" in the Best of IBSx™ Awards for the 2021 NAHB International Builders' Show® virtual experience (IBSx).

Exclusive (GP)2 Technology

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

Class A Fire Rating
for both flame spread and smoke developed

Impressive thermal
and impact resistance

Superior wind load

ASCEND’s (GP)2 compound contains glass particles for added structural stability, strength and heat resistance, while titanium dioxide protects against ultraviolet degradation, and impact modifiers help resist dents and dings. (GP)2’s integral weatherable pigments provide strong fade resistance, even on ASCEND’s dark colors, and its non-moisture-absorbing materials prevent rotting, warping, shrinking and swelling.

Not Just Different.
