wood-composite: wood-composite is often touted as rot-free. this isn't entirely the case, as the organic wood particles are still susceptible to rot. preservatives added to the mixture offset the rot. pvc: the all-plastic content of this decking material is completely impervious to rot.
with rot, the wood typically feels soft and spongy and the outer surface is discolored. paint may be bubbly. when you push a screwdriver into the wood, it will push in easily and the wood will crumble. fungus often accompanies both types of rot.
while composite decks wont rot and are considered more durable than wood, it doesnt mean theyre completely safe from damage. patio furniture or debris from a passing storm may scratch the surface. unlike wood, which you can sand and refinish, composite decking cant be refinished.
composite. composite trim looks just like medium-density fiberboard mdf , but is made to handle weather extremes. it is basically wood fibers mixed with resins with chemicals added for insect and rot resistance. you can cut and rout it just like wood, it comes primes, and it holds paint very well.

rot proof composites. wood/plastic composites wpcs are made from thermoplastic resins, wood flour, and wood fiber. some make use of recycled material, but all are rotproof. composites have no defects, and do not compress like wood. this density poses special problems for fastening and movement.
easy-care composite wood does not splinter or rot, will not shrink or expand, and it doesn't require annual sealing or other treatment. however, most composite decking still does not have the strength of wood and cannot cover as large a distance between support beams.
wood-plastic composites were first introduced into the decking market in the early 1990s. manufacturers claim that wood-plastic composite is more environmentally friendly and requires less maintenance than the alternatives of solid wood treated with preservatives or solid wood of rot-resistant species. these materials can be molded with or without simulated wood grain details.
people choose wood plastic composite wpc or even plastic lumber pl over wood because they want the finished project to resist rot, wood-eating insects, harsh sunlight, and mold and mildew, and
the composite, rot-free polyfiber door frame will last years after wooden frames have deteriorated. composite polyfiber frames will never absorb moisture, splinter or rot like wood door frames, or rust like metal door frames. and on wincore fiberglass entry doors, they are a standard feature. low maintenance.
made from the patented tec process, miratec treated exterior composite trim combines the eye-catching beauty of cedar with the long-lasting performance of an engineered product. because it is not hardboard, miratec trim will not delaminate, is moisture, rot and termite resistant, and is backed by a 50-year limited warranty.
coosa board worked great for the repair i needed to make. im so pleased i made the choice to replace the original wood with a composite since water seems to stay next to the transom due to poor drain location.
