What’s in the Composite Decking?
The composite material used in composite Decking is a wood and plastic mix. Roughly 50% wood, 40% recycled plastics and 10% glue and tints etc. it’s mixed together and then extruded to form either a hollow or solid decking board.
The benefits of mixing these 2 products groups are obvious, you end up with the durable, hard wearing, maintenance free elements of the plastic and the beauty, look and feel of the wood giving you a great looking product that will last for years and years.
WPC/BPC Composite - What does that really mean?
Standard WPC composite decking boards are made of recycled polymers such are PE or HDPE, which are no more and no less than recycled plastic bottles, bags etc.etc. Though this represent a potential good Green commercial hook, those polymers cannot be recycled infinitely! And the boards made out of those polymers are subject to extremely bigger movements and torsions if compared to the not recycled PVC (which can be recycled, is more valuable and doesn’t move as much!).
This is what we need to know when we approach the idea of buying a composite product, especially if you’re willing to install it... a material that moves a lot needs a master deck builder to deal with, otherwise you just trashed your money. In the compound/mixture of the standard wpc decking boards there is even a percentage of natural product, the most common is ! Wow... sawdust! When dropping oil on the floor, my grandmother used to put sawdust on top in order to absorb it and better clean! So again be prepared to dimensional changes according to the percentage of sawdust inside... this again it’s not a that bad thing if you know it before you get it installed (to do it the right way).
