“AZEK Deck” Harvest mono-extruded deck boards are made from foamed polyvinyl chloride (PVC) and cellulosic fibre with ultraviolet Result1 coefficient of linear expansion (thermal). °C−1. <2x10−5. 1.69 x 10−6. Dimensional change coefficient of linear expansion (swelling) oven-dry to vacuum pressure
the coefficient of expansion, meaning a composite board shrinks and expands less with changes in temperature than an all-plastic one does. Wood flour also gives the product a more woodlike appearance and feel. In some decking, wood flour is the only recycled content, with no use of recycled plastic.

When the visibility and quality of gaps is a factor, there are a few basic guidelines to follow: First, follow basic spacing All decking materials whether wood, composite or metal, will undergo some degree of linear expansion with the changes of weather and season. To compensate for the effects of
Clubhouse Cellular PVC Plank Linear Coefficient of Thermal Expansion. (L/L)/°f = (3.2619E -5 ) .125" (1/8). FIGURE 3. FIGURE 4. Here are some best practices: • Pre-drilling is recommended for the best overall appearance with most fasteners. • Always start the screw at a slower speed and maintain a steady speed and
It is also producible at a price point similar to the old products. For this reason, I humbly suggest that for appearance and durability and initial price for prefinished softwood deck, or an unfinished hardwood deck they are just about par Expansion and Contraction of Composites and PVC Decking Expansion of composite.
Many factors affect the long-term performance of wood-plastic composites including the wood/plastic ratio, wood species and fiber size, the type of plastic resin and If you follow their installation instructions for either face-screwing or hidden fasteners, the thermal expansion will be restrained and the deck surface will
To determine the maximum amount of linear movement, we need the coefficient of linear thermal expansion for cellular PVC, which is 0.000032 in/in-F, the length of the board in inches (216), and the maximum temperature swing the product will be exposed to during the year—in this case, 50° F. The
Over time, additives in the rubber and PVC products have a tendency to and PVC Decking. All exterior building materials require cleaning. is no exception. Periodic cleaning of decking will remove dirt and pollen that can feed mold. If mold . Typical ® Values for Coefficient of Thermal Expansion/Contraction.
