High-Performance Weatherproof Composite Sandwich Wall Panels for Outdoors

COOWIN combines the natural appearance of wood with the durability of plastic. Unlike wood decks, which require continuous maintenance, weather protectants, and water-seal products do not need to be applied to COOWIN. COOWIN's surface offers excellent traction and will not splinter or become structurally unfit due to rotting, split, warping, cupping, checks or damage caused by fungal decay or termites.

Composite decking is more expensive to manufacture, but, over time, the maintenance, repair, and or replacement costs of wood decking exceed the initial investment in a COOWIN deck.

Foot traffic, dragging heavy objects across the surface, weather exposure, cleaning products, and the frequency of cleaning (especially with commercial pressure washers, which are not recommended) can all affect COOWIN decking products' finish. To ensure durability, follow our easy maintenance instructions.

No. As proven by testing under accelerated weather conditions, COOWIN is weather-resistant. Our warranty guarantees that it will not corrode, splinter, or become structurally unfit due to rot, splitting, warping, cupping, checks, or damage caused by fungal decay or termites.

Decking is fire resistant, but like wood, the product is not fireproof and will burn or melt at high temperatures. As with other materials, caution should be taken to ensure BBQ's and other potential sources of fire are safe.
