What is the Difference between Capped and Uncapped composite

We are asked many times what the difference is between capped composite sometimes referred to as type 2 co-extruded composite decking and the standard boards that you see in the market, after all composite decking is composite decking, well there is a bit more than that and our article tries to demystify the question.

Capped composite was developed by manufacturers as the composite market evolved as purchasers were looking for more realistic wood effect composite decking and also enhances the scratch and scuff resistance over the basic composite boards.

As the name suggests capped or co-extruded has a secondary manufacturing process undertaken whereby usually a wood pattern is added to the process and then sealed with a further layer of polymer encapsulating the board, this serves also as a further enhancement to the scratch resistant properties, also the additional coating also aids in UV stability of the board. In recent years in line embossing and ink and pigment technology has helped give more lifelike patterns and surface texture further mimicking the real wood effect and also enhances the waterproofing aspects of the board over basic composite decking boards, this obviously comes at a cost over the cheaper variants but with anything this is all about what your budget is and what is the anticipated lifespan of your deck.

In a response to try and meet a cost effective alternative and a half way point between a mono board and a capped board ( co -extruded ) , please do not get confused with basic composite decking which can be embossed through the tooling giving an elevated and wood effect look and the compression and the heating of the boards can give a 2 tone effect, these boards will not have the same level of superiority of a true capped board and the surface of the embossed board can be difficult to repair if scratched or scuffed and clients can be left disappointed if used in a heavy traffic area, a simple groove effect can be repaired of scratches and scuffs with a light sanding with sandpaper or wire wool.
