What fixing system should I use for timber cladding?

Use stainless steel (A2 or A4 grade) or hot-dip galvanised fixings — never plain steel, which will corrode and stain the timber. For face-fixed systems, use ring-shank or screw-shank nails (minimum 50 mm penetration into battens).

Use stainless steel (A2 or A4 grade) or hot-dip galvanised fixings — never plain steel, which will corrode and stain the timber. For face-fixed systems, use ring-shank or screw-shank nails (minimum 50 mm penetration into battens). For secret-fixed systems, use proprietary clip systems that allow boards to expand and contract without visible fixings. Always fix through the thick part of profiled boards, not through thin tongues or edges that may split.
