Buy 3.6m Composite Decking Boards

Family garden with artificial grass, a play teepee and a fire pit seating area

3.6m boards are the easier length to handle and to get through a house, and they usually waste least on a smaller or squarer deck.

All 150mm wide and 25mm deep, in eight finishes with a 10 year warranty. For a long deck, 4.8m composite decking boards give you fewer joins — the colours guide covers the finishes.

All eight colours are made in the 3.6m length at £25 a board, about £46 per square metre. Boards are hollow wood-plastic composite with a grooved face on one side and an embossed woodgrain on the other, so you choose the look and the grip when you lay them. A 3.6m by 3m deck takes 20 boards and goes down on composite battens or plastic joists at 350mm centres with hidden clips, no visible screws. Every board carries a ten-year warranty.

Size the deck to the board and there is no waste: 3.6m boards suit decks up to 3.6m deep, and two rows with a double joist under the join cover 7.2m. The cost guide prices three decks in full, the clips guide gives the clip count, and free samples show both faces of every colour. Order before 2pm for same-day dispatch; kerbside delivery in 2 to 4 working days, free over £190.

Frequently asked questions

How much is a 3.6m composite decking board?

£25 a board in every one of the eight colours, about £46 per square metre laid. Boards are 150mm wide and 25mm deep, hollow, with a grooved face on one side and a woodgrain face on the other.

How many 3.6m boards do I need?

A 3.6m by 3m deck takes 20 boards. Divide the deck width by 156mm, the board plus its 6mm clip gap, and round up; add one spare. Tell us the deck size and we will list boards, clips and trims in one order.

When is 3.6m the right length?

Decks up to 3.6m deep with no waste, or larger decks laid in rows with a double joist under each join. 3.6m boards are easier to carry through a house than 4.8m and turn a corner in a hallway.

What else does a 3.6m deck need?

A frame of composite battens or plastic joists at 350mm centres, one hidden clip and screw per board per joist, a fascia board or L-trim for the visible edges and end caps for any cut end on show. All in matching colours.
