thermal expansion of composite fence

The product concept has evolved rapidly into railing, fencing, trim, automotive parts, and other applications. Adding wood to plastic to make WPC reduces the formula cost, raises the modulus of elasticity, and lowers the coefficient of thermal expansion. These benefits come at a cost, however: Extruding 

Bufftech leads the vinyl fence industry with the widest array of styles, colors and textures including smooth Our vinyl fences feature excellent fire performance properties and received a Class A rating for flame spread for thermal expansion and concealed fasteners, and you have a sleek, clean look without brackets

By far the biggest sector of the wood plastic composite (WPC) industry, this segment accounts for deck board and railing, molding and trim, fencing and door and . “Pulp cellulose fiber has zero coefficient of thermal expansion,” he claims, “and, because it has no lignin, the fiber doesn't photo degrade like wood flour.”.

If you read the installation instructions for fiber cement, or composite wood siding and trims, you'll see the manufacturers recommend gapping between boards. The Change in Product Length (unrestricted) = The coefficient of linear thermal expansion for cellular PVC x the length of the trim x the maximum

Wood plastic composites weather the recession and questions about their weatherability. Deck Harvest Collection is manufactured using the company's proprietary Procell cellular PVC reinforced with flax fiber, which mitigates the effects of thermal expansion and contraction, allowing narrower gaps between boards.

This measurement determines the vinyl material's rate of contraction and expansion due to heat changes. The vinyl specimen is alternately exposed to hot and cold baths the lower the number, the smaller the amount of deflection. The results of this test have to be factored into the design of the fence pieces to provide 

Routed rails and fence posts. Bufftech vinyl fence systems feature precision routed rails for safe, secure picket attachment and easy assembly. Bufftech's routed fence posts provide a secure connection that allows for thermal expansion season after season. Concealed fasteners. All Bufftech vinyl fence systems feature

Values listed are representative for short term loading (such as livestock pushing on fence). The long term creep 

IMPORTANT: Through temperature changes of seasonal weather, Wood Composite Fencing will experience thermal expansion in the pickets and cross rails. To anticipate this expansion movement, our instructions include installation steps which need to be followed to prevent pressure from building in the fence during the 

Thinking of replacing your wood deck with rot resistant composite decking material? Read this first. The longer the piece of decking, the greater its expansion and the more you have to account for this when building your deck. Check the product's end gap chart, which correlates the space needed
