Decking boards are a simple, yet effective way of sprucing up your garden. Decking can be used in a number of ways: as part of garden landscaping, to extend living areas of houses, and as an alternative to stone based features such as patios. 

We supply two types of decking both grooved to aid water run off:

EX32 X 125 ECONOMY DECKING BOARD - Finished Size - 26mm x 120mm (+/- 1mm)

EX38 X 125 HEAVY DUTY DECKING Board - Finished Size - 33mm x 120mm (+/- 1mm)

Lengths available - 3.0mtr, 3.6mtr, 4.2mtr, 4.8mtr

Please note that their should be a minimum of 5mm gap between each board, this will help with movement from the timber during the change in seasons.

When laying a sub frame, (Joists) we recommend using a suitable size timber to support the structure ensuring that the centres between each joist do not exceed 400mm (16"). This sub frame must be run in the opposite direction to the decking.

Beware if you order over the phone make sure of the thickness you ask for e.g. 32mm comes as 25mm
I asked for 32mm expecting it fo be 32mm but NWT must have a different tape measure as it comes 25mm!
