Owens Corning WearDeck Composite Decking: Specs & Warranty

Owens Corning’s composite decking line, branded WearDeck, is made from HDPE reinforced with the company’s glass fiber technology — the same reinforcement approach used in its insulation and roofing products. Owens Corning acquired WearDeck’s manufacturer in 2022, and the line now carries a 25-year UV warranty plus a limited lifetime warranty against termites, mold, mildew, splintering, and warping. This guide covers what WearDeck is actually made of, its real specs and warranty terms, how it compares to standard wood-plastic composites, and where to buy it.

What Is Owens Corning WearDeck Composite Decking?

WearDeck was an independent composite decking and structural lumber manufacturer before Owens Corning acquired it in 2022. The boards are made from high-density polyethylene (HDPE) rather than the wood-flour composite blend many competitors use, reinforced with Owens Corning’s glass fiber technology for added strength. Standard board profile is 5/4-inch by 6-inch, available in 12, 16, and 20-foot lengths.

If you’re installing a full deck, hidden fasteners keep the board faces free of visible screw heads — the same approach covered in the installation section below.

WearDeck Specs, Colors, and Warranty

WearDeck’s biggest differentiator is heat performance: seven of its standard colors are rated to stay under 98°F in direct summer sun, and three “barefoot-rated” lighter colors stay under 95°F — both notably cooler than many dark composite boards, which can exceed 140°F in full sun.

Spec	WearDeck
Material	HDPE with glass fiber reinforcement
Board profile	5/4 in x 6 in
Lengths	12, 16, 20 ft
Surface temp (standard colors)	Under 98°F in direct sun
Surface temp (barefoot-rated colors)	Under 95°F in direct sun
UV warranty	25 years
Structural warranty	Limited lifetime (termites, mold, mildew, splintering, warping)

How to Install Owens Corning Composite Decking

WearDeck installs like most grooved-edge composite decking: boards sit on standard 16-inch on-center joist spacing (check Owens Corning’s current installation guide for spacing at longer spans), with hidden fasteners clipped into the grooved edges between boards to keep the surface free of visible screw heads.

Leave the manufacturer-specified gap between board ends for thermal expansion — composite boards expand and contract with temperature more than solid wood does. For general deck-building cost planning beyond the decking material itself, see our deck cost breakdown.

Owens Corning vs Standard Wood-Plastic Composite Decking

Feature	Owens Corning WearDeck	Standard Wood-Plastic Composite
Base material	HDPE + glass fiber	Wood flour + plastic blend
Heat performance	Under 98°F (95°F barefoot colors)	Varies widely; dark colors often 130°F+
UV warranty	25 years	Varies by brand, often 25-50 years fade warranty
Moisture absorption	Low (no wood flour to absorb water)	Higher in wood-flour-heavy blends

Maintaining and Cleaning an Owens Corning Deck

• Sweep and rinse regularly: Removes grit that can dull the surface finish over time.
• Use a composite-safe cleaner: Avoid straight bleach or pressure washing above the manufacturer’s recommended PSI, which can damage the surface texture.
• Address stains promptly: HDPE-based decking resists staining better than wood-flour composites, but oil and grease spills should still be cleaned up before they set.
• Check the warranty terms before using a new cleaning product: Some cleaners can void a composite decking warranty — confirm compatibility first.

Frequently Asked Questions

What makes Owens Corning composite decking different from other brands?

Owens Corning’s decking line, branded WearDeck, uses HDPE (high-density polyethylene) combined with the company’s glass fiber technology — the same reinforcement science Owens Corning uses in insulation and roofing — plus a heat-reflective pigment blend most competing composites don’t use.

Can I install Owens Corning WearDeck myself?

Yes — WearDeck installs like most grooved-edge composite decking, using hidden fasteners between boards on standard joist spacing. It doesn’t require specialty tools beyond what any composite decking installation needs, but check Owens Corning’s installation guide for the exact fastener spacing and gap requirements that keep the warranty valid.

Is Owens Corning decking eco-friendly?

WearDeck is made primarily from HDPE, a recyclable plastic, reinforced with glass fiber rather than wood flour used in some composites — Owens Corning markets this as reducing the wood waste input compared to wood-plastic composite decking. It is not a certified 100% recycled product; check current product documentation for the exact recycled-content percentage.

How hot does Owens Corning WearDeck get in the sun?

Owens Corning rates seven of its standard WearDeck colors to stay under 98°F in direct summer sun, and three “barefoot-rated” colors to stay under 95°F — both meaningfully cooler than many dark-colored composite decking boards that can exceed 140°F on a hot day.

WearDeck’s HDPE-and-glass-fiber construction and heat-reflective colors are the two real differentiators worth weighing against standard wood-plastic composite decking — confirm current pricing and color availability with a local dealer before you buy.
