Halflap cladding is a machined profile supplied with a smooth finish and an overlapping edge detail to create a waterproof façade. The halflap profile creates a clean linear appearance which is ideal for contemporary new-builds and modern extensions to older properties. Halflap cladding can be fixed vertically and horizontally although care should be taken to select the correct profile version (Ref technical page).
Our standard range of halflap profiles offers a choice of shadow gap depth ranging from 2mm to 11mm to suit specific design requirements. Alternatively we can produce bespoke halflap profiles to customer specifications.
All air-dried species can be machined to halflap. The most popular choices are British sweet chestnut, British oak and Canadian western red cedar.

Begin at the bottom, ensuring that the first board is level with the lap that is adjacent to the wall, pointing upwards. For boards up to 150mm wide, use a single fixing located 25 – 30mm above the lower lap. Never nail through the lap joint. For boards over 150mm, use two fixings, with the second located a further 65 – 75mm above the first to allow for some dimensional movement.Vertical attachmentStart at one corner, with the lap that is adjacent to the wall, facing away. Nail as with the horizontal attachment.
