Unlike traditional vinyl siding, fiber cement, engineered wood, or steel siding, ASCEND was developed as a modern composite cladding system that blends multiple material technologies into one high-performance exterior product. The result is a lightweight panel that installs efficiently while delivering exceptional durability and long-term curb appeal.

What Is Glass-Reinforced Polymer?

Glass-Reinforced Polymer, commonly called GRP, is an advanced composite material that combines engineered polymer resins with reinforcing glass fibers. The glass fibers dramatically increase stiffness, strength, and impact resistance while keeping the finished product lighter than many traditional exterior materials.

GRP technology has been used for decades in demanding industries including aerospace, marine, transportation, infrastructure, and industrial manufacturing because it offers an excellent balance of strength, durability, and corrosion resistance.

Why Glass Fibers Matter

Glass fibers act as reinforcement within the composite material. Rather than relying solely on plastic, the fibers help distribute loads throughout the panel, increasing rigidity while reducing the likelihood of cracking or deformation under normal service conditions.

Is ASCEND Vinyl Siding?

No. Although ASCEND is installed similarly to many lap siding products, it is not vinyl siding. Vinyl siding is manufactured primarily from PVC, while ASCEND uses a proprietary Glass-Reinforced Polymer composite formulation with reinforcing fibers that provide different performance characteristics.

How Does ASCEND Compare to Other Siding Materials?

Why Was ASCEND Developed?

Modern homeowners often want the beautiful appearance of painted wood without the continual scraping, painting, caulking, or refinishing associated with traditional wood siding. ASCEND was engineered to provide that premium aesthetic while significantly reducing long-term maintenance requirements.

The product also addresses common contractor concerns by offering relatively lightweight panels, simplified installation, integrated insulation, and consistent factory manufacturing.

Does the Material Resist Moisture?

Glass-Reinforced Polymer does not absorb moisture like wood products. When installed according to the manufacturer's instructions over a code-compliant weather-resistant barrier, ASCEND helps create a durable exterior wall system capable of performing in demanding climates.

Is ASCEND Heavy?

Despite its strength, ASCEND is considerably lighter than many cement-based siding products. Its lighter weight can improve handling on the jobsite and reduce installer fatigue while still delivering excellent rigidity and performance.

Why Contractors Like Composite Materials

Contractors appreciate products that install efficiently, require fewer callbacks, and perform consistently over time. ASCEND's composite construction helps provide a rigid panel with integrated insulation, helping create straighter wall lines and a premium finished appearance.

Is ASCEND a Good Choice for Iowa and Illinois?

Eastern Iowa and Western Illinois experience everything from freezing winters and hot, humid summers to hail, high winds, and rapid temperature swings. These conditions demand exterior products engineered for long-term durability.

ASCEND's composite construction, integrated insulation, and low-maintenance design make it an attractive option for homeowners looking for a premium exterior cladding system capable of handling Midwest weather when installed according to the manufacturer's instructions.

The Bottom Line

ASCEND Composite Cladding is manufactured from proprietary Glass-Reinforced Polymer reinforced with long glass fibers. This advanced composite construction provides excellent strength, dimensional stability, moisture resistance, and low maintenance while delivering the timeless appearance of painted wood.

For homeowners seeking a premium alternative to vinyl, fiber cement, or engineered wood, ASCEND offers an innovative composite solution designed to provide lasting beauty and reliable performance for decades.
