About this product
The Lite range is our most affordable range of composite decking, delivering a perfect blend of affordability and durability in a lightweight board. Featuring a durable square hollow design with an embossed woodgrain aesthetic and reversible finish, NeoTimber® Lite composite decking is perfect for garden decking, and also balconies where a lightweight, strong board is highly desirable. Low-maintenance and designed to withstand whatever the weather can throw at it, our Lite decking comes with a 10-year residential warranty.
Why choose Lite composite decking?
- Embossed Woodgrain Finish. The Lite range has a deep, durable, etched woodgrain texture that leaves competitors looking (and feeling) rather flat – even at the most affordable price point in our range.
- Reversible Finish. Dual-sided boards give you the option of an authentic woodgrain finish for a natural look, or a grooved pattern for a more contemporary feel. You can even combine the two – woodgrain for the main area and grooves as a striking edge pattern.
- Square Hollow Design. A robust square-hollow core uses less composite material, stripping out cost and weight – ideal for garden makeovers on a budget, or applications needing a strong, lightweight board such as balconies.

Installation & Care
Before you start: store boards flat and allow them to acclimatise on site before fitting. Leave appropriate expansion gaps at board ends and edges, as composite expands and contracts with temperature.
Fitting: install onto a suitable, well-ventilated subframe (composite, plastic or treated timber joists) with joist centres no greater than recommended for the range. Secure with the matching NeoTimber clips and screws, fitting along the length of the boards.
Routine care: clean every 3–6 months using warm soapy water and a soft-bristled brush, working along the length of the boards. A jet wash up to 3100 PSI may be used with a fan attachment kept at least 250mm from the surface.

Installation Guide
A professional-finish composite deck can be installed by a competent DIYer over a weekend.
Plan and measure your area
Mark out your deck area and calculate the total square meterage. Add 10–15% for cuts and wastage.
Prepare the sub-frame
Install pressure-treated C24 timber or aluminium joists on a firm, level base. Joist spacing must not exceed 400mm centre-to-centre for perpendicular boards, 300mm for diagonal laying.
Lay the first board
Start at the most visible edge or against the house wall. Allow a 5mm gap from any fixed structure. Use the supplied starter clips — slot into the board's groove and screw into each joist.
Continue laying boards
Press each board firmly into the previous clips, then add middle clips to the exposed groove. Check alignment every 3–4 boards. Stagger butt joints by at least 600mm across rows.
Cut and finish edges
Use a fine-tooth circular saw with the cut side face-up. Seal cut ends if the deck will be exposed to standing water at that edge.
Add trims and fascia
Finish exposed edges with matching fascia, corner trims, and skirting. Fit edge boards using stainless screws colour-matched to your boards.
