Extractives
Western red cedar contains reactive oils, which will corrode ferrous metals. All fixings used in conjunction with western red cedar must be stainless steel. The brown oil can leave unsightly brown stains on the surface of the shingles and will stain any porous materials below the cladding.

How to fix
Separate adjacent shingles by 6 – 9mm. Following joints should be offset by at least 38mm. Use two nails for each shingle, 19mm – 25mm from the edge and 38mm – 50mm above the end position of the following shingle.

Battens of at least 25mm x 38mm to be set at centres equivalent to the shingle exposure. The exposure is the portion of the shingle exposed to the weather.

Nail type
31mm stainless steel ring shank nails
