pvc vs composite: what is the best maintenance-free

pvc vinyl decking and heat expansion. first, any plastic material is subject to linear expansion. when exposed to heat, the molecules inside the plastic expand. engineers take this into account during design. they calculate the estimated linear expansion coefficient. pvc vinyl decking has an expansion ratio of 54-100.

how much gap should i leave for expansion or contraction

how much gap should i leave for expansion or contraction when installing? as temperatures fluctuate, composite deck boards will naturally experience thermal expansion and contraction. thats why the board ends should never be installed tight against one another.

what is the coefficient of expansion of composite decking

coefficient of thermal expansion of wood - wood plastic composite deck,wood andwhile wood has always been a traditional material when it comes to porches, patios and decks, composite decking is a modern counterpart that combines natural

composite and plastic decking

despite the significant thermal expansion that can occur in unrestrained boards, seven trust recommends butting end joint tight. if you follow their installation instructions for either face-screwing or hidden fasteners, the thermal expansion will be restrained and the deck surface will remain dimensionally stable, according to the manufacturer.

plastic vs. composite decking hgtv

but plastic decking has its problems. it might expand and contract in certain climates, loosening joints and making decks unstable. in hot, sunny areas, plastic decks can get very hot on the soles of the feet and actually radiate heat, making them uncomfortable.

figure 3. one way to deal with the greater expansion and contraction of all-plastic decking is to avoid long lengths. adding planks perpendicular to the main run not only adds interest, it allows for expansion joints.

decking: attaching composite deck boards diy deck plans

always leave the deck boards extending past the outside joist when lying decking. chalk a line once all the decking is down and cut with a skill saw. when cutting off maintenance free decking, cut off the deck boards when all of the decking is complete. it is important to cut off maintenance free all at once due to the expansion and contraction

composite decking vs wood

expansion and contraction of composites and pvc decking. building with man-made decking is very different than wood. when you build with wood you keep everything as tight as possible for best results. better builders build in spaces that help wood last longer but that is uncommon wisdom in the decking business.
