water absorption of composite deck

Like other top quality composite decking products, ecodek requires no staining, painting or treating throughout its long life. This is because the polymer (plastic) content limits moisture absorption to very small amounts, below 1% for ecodek *, compared with over 25% for untreated timber. Water absorption is the cause of 

The cooler underside of a deck creates the ideal conditions for the accumulation of water condensation, and the more moisture there is in the air—I'm looking at you, Georgia—the more condensation will form on your boards. With unprotected composite decking, this moisture gets absorbed into the boards 

Softwoods. Softwoods are softer and less durable than a hardwood. Due to their less complex composition, softwoods are prone to absorb more moisture and have a shorter life than hardwoods. Softwoods will have much larger spaces between the annular rings due to the high rate of growth, which produces a less complex 

Unlike wood, Dura Deck won't rot or splinter, and never needs sanding, painting, or treating. Whether you're building a new pool deck or replacing a previous wooden one, you'll never have to worry about warped boards or splinters. Dura Deck has excellent anti-slip resistance with a low water absorption rate, meaning that 

The M Word As many deck owners have discovered, wood-plastic composites can support mold and mildew growth, just like the wood they're designed to replace. That's part of the tradeoff involved in using wood flour in the formulation. “Solid wood absorbs water pretty readily,” Stark says. “In composites 

Water has little effect on the plastic components. For example, even though some of the entirely-plastic cellular PVC decking products have the highest water absorption values for any decking, the boards do not show end flare or curling due to water uptake. This is because there is no wood there to swell.

I.Dekk decking's patented formula has high fade resistance and very minimal water absorption. Its strong I-Beam construction creates a stronger deck board that won't rot or mold.

This dime-sized mushroom growing on a wood composite deck is one of many unwelcome surprises weathering can cause in wood-plastic composites. Work in Europe is also addressing issues of aging and weatherability, including the need for tests of water absorption, weight loss, weatherability, aging, color fastness, 

This study was conducted to clarify the mold resistance and water absorption of wood plastic composites (WPC). Since Morris and Cooper observed the presence of fungal decay and discoloration on WPC deck boards in Florida (Morris and Cooper, 1998), fungi resistance of WPC has been studied by 

How long a decking material lasts largely depends on the degree to which it resists water. Moisture absorption can lead to rot in both wood and composite decking, along with mechanical damage from shrinking and swelling. Class-action lawsuits involving composite decking failures have addressed rot, 

than the percentage humidity within the board, a Geolam composite wood board will expand as it absorbs humidity. If the board were submerged in water for 365 days at a temperature of. 23°C (70°F), the saturation point would be reached after 290 days, and the expansion associated with this absorption of water would.

Testing proves that the water absorption rates of some composite decking products may increase significantly when exposed to water for an extended period. Composite decking products with higher water absorption rates can experience dimensional change, decreased mechanical performance and are more susceptible 

The boards have minimal water absorption which means they are highly slip resistant and can be used around pools and wet areas. Due to the increased durability of the boards composite decking has a much longer lifespan than its wooden ancestors, our own ranges come with a 15-25 year guarantee, but we would

This plastic content gives the deck boards a very long lifespan without the need to treat or seal the decking over its life, the decking has on average a 1% water absorption rate. While the wood content allows the decking to retain that wonderful tactile feeling you get when touching wood. How is it better than normal wood
