Composite wood deck is an alternative to timber, which has a low maintenance cost. The wooden deck was a status symbol in the fifties; composite ones came in the market in the 90`s capable of a longer life span and maintenance-free. It is made of wood fibers and plastic new or recycled. Some composite decks are 100% polyvinyl. The composite decks are slightly heavier than wood decks of the same size because of the components, colors, and agents added to protect it from harsh weather and insects. Composite decks do not rot or split, which is a common occurrence in wood decks.
Types of decking
Composite decking comes in two forms; solid composite decking and hollow composite decking. The former one is heavier than the latter one and has a more natural appearance. However, it is more prone to fluctuations in temperature. The hollow decks cost less than solid ones and need care and precaution during installation. The initial cost of composite decking is more than wood decking, but in the long run, it is more cost-effective as it has a little maintenance cost. Composite boards are longer than wooden boards and maybe as long as 20ft. The coloring agent is incorporated while manufacturing, so after installation, you need not paint it further.
Do Not Bend
Composite decks do not bend but can snug and bulge. This mainly happens for improperly positioned floor joists during the fitting process.The abrupt change in temperature can cause composite decks to sag or bulge. Composite decking is typically placed wider, so the expansion due to heat does not create snug or buckle. Composite decks are resistant to fading due if exposed to direct sunlight over a long time. It tends to fade. It may become hot when exposed to direct sunlight, but would never melt. It is better to use in shaded places. Composite decking is stain resistant, but quickly clean up the litter. Frequent sweeping and washing with detergent and water twice a year all is needed for the maintenance.
The complex manufacturing process makes the composite decking boards expensive than the ordinary wood boards. The initial cost of composite decking is nearly double than wood decking. The boards are a part of the project, which includes a framework. Moreover, composite decks come with a warranty, which is not available in timber. When you consider the long term cost, it gives full value to the money spent. Decking Calculator helps you to assess the cost-effectiveness of composite decking.
