Specialists in premium composite products

Wood plastic composite (WPC) decking is a blend of recycled wood and plastic that would have otherwise ended up in landfill. Composite decking offers exceptional durability, resilience and performance that you can’t get from pure wood. It doesn’t split, chip, warp or rot – perfect for withstanding the elements! Our composite decking is barefoot safe, won’t splinter and is slip resistant unlike wet wood.

Composite decking is designed to be strong and durable. As a low-maintenance alternative to timber, you can expect it to last for many years with minimal upkeep. All our capped composite decking products come with a 25 Year Limited Warranty for residential applications and 10 years for commercial applications.

Our contemporary composite deck boards (HD Deck® XS, HD Deck® 150 and HD Deck® 3D), which all contain the grooved design, are made from a single extrusion of hard wood flour and recycled HDPE plastic composite – making them a long-life alternative to timber decking. Our wood grain effect composite decking (HD Deck® Dual and HD Deck® Pro), is also manufactured from hard wood flour and recycled HDPE plastic, but has a tough polymer shell applied to its exterior. This encapsulates the product and provides a defensive barrier to offer improved performance against the elements. This product has all the great features of traditional composite decking, with the added benefits of improved stain, mould and fade resistance.

Our composite decking products contain hard wood flour and recycled HDPE plastic and this minimises the natural UV fading effect. This being said, you should expect some fading during the first 6-12 months while the colour pigments stabilise, before weathering naturally to a similar colour pallet. Whilst every effort is made to match our colours from batch to batch we recommend fitting HD Deck® from the same pack. Capped products such as HD Deck Dual® and HD Deck® Pro have a higher degree of UV stability to uncapped products such as HD Deck XS®, HD Deck® 150 and HD Deck® 3D.

Composite Prime’s PRO Installer scheme is a network of installers that we trust to bring your decking plans to life. Our network of installers have been chosen because of their high quality of work and professionalism, but they are all third party’s and thus you should do your due diligence before entering into any contract with them.

All of our composite decking products are tested for slipping in wet and dry conditions to EN 15534-1:2014 Section 6.4.2 and all of our results including in wet conditions achieve a Low Slip potential grade. For more on our results please see here.

Yes, Composite Prime® HD Deck® is manufactured with the highest quality materials and processes available. All of our products are covered by a limited manufacturers warranty and are there to cover against product failure and manufacturing defects to give you peace of mind. For more information please see our warranty documents here.

We would ask that in the first instance you contact one of our Pro Installers and they can assist you with this, alternatively you can use our 3D deck builder, Prime Design, to visualise and plan your project but also create a bill of materials.

This is the joist spacing that we test the board to. It’s very common for composite decking to be installed at closer centres than of timber. Please remember to follow the fitting instructions when installing your deck, you can find all our fitting guides in the resources section.
