A utility grade primarily used for undercoursing prior to final coursing application.

Certigrade™cedar shingles are produced by cutting blocks from the log to the desired length. Shingles are then taper sawn to size. This type of smooth sawn architecturally uniform cedar shingle is preferred for its natural and tailored appearance and is used on traditional and modern residential and non-residential structures.

Certi-Label™ Confidence
Not all cedar shake and shingle products are alike. Certi-label products, manufactured by Cedar Shake & Shingle Bureau members, assure you of the highest quality standards. Member mills have committed to consistent quality through independent third-party inspections by accredited agencies. Each bundle of product has the mill's distinctive Certi-label tucked under the bundle strap. Asking for "the blue label" or "number one blue label" is not specific enough. Cedar Bureau members' products are the only ones with the Certi brand name on the label.

Coverage per bundle (approx.) m2
1 Bundle on roofs with 19º+ pitch 1.50m2

Approximated Nails usage guide - 1 kilo of 1.8 x 31mm Stainless Steel Annular Ringshank Nails will be required to fix 4 bundles of shingles.

Recommended use - A utility grade primarily used for undercoursing of sidewalls prior to cladding applications. Customers have previously used Green Label shingles for economy applications and secondary buildings where an economy product is acceptable such as gazebos, sheds and garden houses.

Batten Spacing - Space battens to coincide with the weather exposure. Spacing between adjacent shingles (joints) should be a minimum of 6mm and a maximum of 9mm.
Joints in any one course should be separated not less than 38mm from joints in adjacent courses and in any three courses, no two joints should be in direct alignment.

Coverage Guide

When working with timber it should be expected that although ‘on-grade’, occasional boards may have minor imperfections that will require ‘working’ if you wish to eliminate. Examples include raised grain, small splits, minor handling marks, sticker marks etc – all of which can easily be remedied by trimming, gluing or sanding. In most cases imperfections can be removed with very little effort, and the small amount of off cuts generated as a result will be absorbed in the normal cutting and selection allowance.

Western Red Cedar is the ultimate green building material. It is legally, responsibly and sustainably harvested in the publicly managed forests of British Columbia, Canada. Less than 1% of standing timber is harvested each year.

For each tree harvested, three are replanted to ensure the forests will exist in perpetuity. Western Red Cedar has a low impact on the environment throughout its life cycle. It requires significantly less energy to produce than man-made alternatives and is bio-degradable.
