Canadian Western Red Timber Cladding is a durable softwood.

This timber is slow grown, naturally durable, stable, light weight and has a natural beauty and warmth complemented by a uniform fine grain which makes it easy to work with and finish. It is a soft timber and can be nailed or screwed. However, as it is a soft timber it may be more prone to physical damage such as splitting and indentation/bruising, so care should be taken.

Most Western Red Cedar used in the U.K. is imported from North America and Western Canada.

Homegrown Western Red Cedar has been growing in our country for 90 years plus. The UK/ Homegrown counterpart is faster grown, therefore is only a Moderately Durable softwood.

Homegrown Cedar is significantly cheaper over North American and Western Canadian alternative and from a carbon foot print perspective, is worth considering as the product does not have to travel half way round the world to our country.

Treatments & Bespoke Products


Treatments can be applied to various cladding species to enhance or alter their colour or give them long term protection against the elements.

The treatment process impregnates wood cladding with a blend of preservative and Brunnea pigment.

From experience to date, exposure trials and commercial practice, you can expect the appearance of Brunnea treated wood to enrich after initial exposure.

NORclad Lite provides a 30 year warranty against rot & fungal decay.

The treatment process impregnates wood cladding with preservative and copper.
Without any pigment in the treatment, your timber cladding will naturally weather to a silver grey over time.

Bespoke Products

The requirements of every project is different and we’re here to help ensure that the cladding you specify is the right one for you. We offer bespoke services ensuring that your cladding is fit for purpose.

The NORclad range of cladding is available with fire protection to the following British and European standards.

Euroclass B-s1-d0 (s1 Smoke Production – d0 Flaming Droplets).

BS EN 13823 & BS EN 11925-2 Single Burning Item Equivalent to UK “Class O” BS 476: Part 6 & BS 476: Part 7

Aerofoils and Bespoke items are an area where we have no ‘standard’ Timber Species, Size, or Profile.

A great way to give an elevation a softer appearance, to over clad elements of a large structure that would otherwise be quite intrusive – the large slab side of a car park or sports hall for instance.ey over time.

Use timber decking to modernise your outdoor area.

Timber Decking can be machined from any species that we offer, although a timber such as Western Red Cedar is very soft, and could damage easily. The most popular species that we offer for our decking is European Redwood, in either an Unsorted, or Fifths grade.
