Douglas Fir Rain Screen External Cladding

Our Douglas Fir Rain Screen External Cladding is rain screen (splayed) cladding in Douglas fir, for external use.

About Douglas fir

A strong, hard-wearing softwood that's a popular alternative to oak cladding.

Left untreated it weathers to silver grey.

Profile and fitting

Rain screen (also called splayed) cladding gives bold shadow lines between boards. The board edges are cut at 45°.

Grades and options

• First Grade: mostly clear of knots, with some knots up to 5 mm allowed and a small amount of sap on the underside only.
• Character Grade: knots, splits, sap, historic insect damage and other defects without limitation, as long as they don't affect usability.
• End matching (tongue and groove on the board ends) lets you place joints where they fall rather than on a batten, which speeds up fitting and reduces wastage.

Sizes and pricing

• 142 x 20 mm (visible face 122 mm): from £25.49 per m² ex VAT

Good to know

• Natural timber varies: expect some differences in colour and grain from board to board and from the photos.
• Boards left exposed to changing weather before fitting are likely to cup, warp and split. We suggest fitting between October and April where possible, within 7–14 days of delivery.
• Sizes are nominal and can vary slightly with moisture content.
• Not sure? Order up to two cladding samples first.
