With their distinctive natural appearance, Western Red Cedar shingles will lend a touch of individuality to your project. Their rich, warm colour tones and texture will add character and blend naturally with the environment.
Fivex is the name given to shingles, which have a nominal length of 16” / 406mm and a butt thickness of just over 10mm. Perfection shingles are 18"/457mm in length and have a but thickness of 11.5mm.
Number 3 Grade, Black Label shingles are sold in bundles. Each bundle covers up to 1.63 m2 of roof area. Bundles contain shingles of random widths, with the minimum being 64mm.
Number 3 Grade, Black Label are a bi-product of higher-grade shingles. Manufacturers do not set out to produce this grade; instead, they accumulate in limited quantity during the production of Number 1 Grade. As such, they are stocked as and when we can source them.
Certigrade™ is your assurance of quality. Western Red Cedar Shingles bearing the Certigrade trademark are inspected by legitimate, third party agencies, accredited by the Cedar Shake & Shingle Bureau.
If left in their natural state, cedar shingles will gradually weather to an attractive silver grey. Typically, this change will take effect after a 6 – 9-month period. A finish may be applied to maintain or enhance the natural colour or, if preferred, change the colour entirely. Cedar shingles will readily accept a penetrating stain such as Sansin SDF, which can be supplied separately for site application.
Western Red Cedar heartwood has a proven life expectancy of 60 + years due to the presence of natural oils that act as preservatives to help the wood resist decay. It has a durability rating of 'Class 2' according to BSEN350:2.
Western Red Cedar has twice the stability of the most commonly available wood species. It does not excessively shrink, swell or warp through changes in moisture or temperature. Over time it will tend to lie flat, stay straight and hold fasteners tightly.
Ability to withstand extreme weather
Once nailed in position, cedar shingles have an outstanding level of rigidity. The extra strength gained from the 3-ply overlapping method of installation makes them highly resistant to extreme weather such as wind-driven snow and rain, ice, sun, and even hurricane-force winds. Cedar shingles are 'Uplift tested' to withstand wind speeds of up to 173mph.
Western Red Cedar shingles breathe, providing an extra degree of ventilation.
Cedar shingles use a low level of energy to produce and transport, and their production emits a low level of pollution when compared to other materials.
Wood offers a high degree of thermal insulation when compared to other materials, with 413 times the thermal resistance (R-value) of steel, 2,000 times that of aluminium, and eight times that of concrete. With a value of K=0.1067 W/m°C, Western Red Cedar offers an unusually high degree of thermal insulation. This ability to slow the passage of heat and cold is due to its unique cellular structure, which slows the passage of heat and cold, thus reducing the amount of energy needed to heat and cool buildings.
The fact that cedar shingles are up to one-tenth of the weight of traditional roofing materials means that savings can be made in the supporting structure. Their low weight also makes shingles easy to transport and handle.
Western Red Cedar shingles are lightweight, easy to handle, and easy to cut and work with standard tools. They are quick and easy to install – each shingle is nailed to a batten using two nails.
Western Red Cedar used to produce shingles is a renewable and sustainable resource.
When trees are harvested, new trees are planted. These growing trees emit oxygen and absorb carbon dioxide, cleaning the air, and creating a healthier environment.
Western Red Cedar shingles are renewable; sustainable; their manufacture produces low emissions and no wastage; they contribute to providing energy-efficient buildings, and they are recyclable. This makes them a truly 'green' building material.
A good part of cedar shake and shingle wood fibre supply comes from salvage logging. The salvage logging process involves harvesting sections of logs that would otherwise be left on the forest floor as they are unusable for other forestry business operations. As cedar is naturally decay-resistant, this salvage fibre is in pristine condition and allows the industry to make full use of a valuable natural resource.
Waldun Premiums are made by Waldun Forest Products, a family company that dates back half a century and who is today one of the largest and most respected names in the cedar shingle and shake industry.
The Waldun name is synonymous with quality. In 2012, Waldun shakes were chosen for the restoration of Philadelphia's Independence Hall - perhaps the most important historic building in the United States. It was here that both the Declaration of Independence and the US Constitution were debated and adopted.
Silva's relationship with Waldun goes back over 15 years. Our partnership with this leading manufacturer enables us to offer our customers the most comprehensive range and extensive stockholding of cedar shakes and shingles in Europe.
In addition to shingles, Silva also provides pre-formed shingle hip and ridge units, battens, Tyvek® breathable membrane, stainless steel nails, and a wide range of finishes and cleaning products – everything you need to complete the job.
1 kilo of 1.8 x 31mm Stainless Steel Flat Head Annular Ringshank Nails will be required to fix 4 bundles of shingles.
A utility grade for economy applications and secondary buildings where an economy product is acceptable. e.g. garden structures.
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.

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, glueing or sanding. In most cases, imperfections can be removed with very little effort, and the small number of offcuts generated as a result will be absorbed in the normal cutting and selection allowance.
