UK Larch Timber Cladding2022-05-18T10:56:01+01:00


British Larch is an indigenous specie which grows in various parts of Britain which gives an improved carbon footprint to local projects and developments over Siberian Larch.

British grown Larch, known as Larix Europaea, is naturally moderately durable softwood in view of its high resin content with a colour that ranges from a light-dark brown heartwood to a white sapwood.

Benefits of Larch

Compared to Siberian Larch, British grown Larch is typically warmer in appearance having a rich heartwood colour, it has a greater number of knots and perhaps more grain character.

Knots are brown and can be scattered and frequent, and they may loosen and weep resin for 12-18 months. It will colour down to a silver grey if it is not protected as soon as installation is complete with a good quality semi or fully translucent UV-radiation protective coating. It is a very strong and hard-wearing wood.

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.

NORclad will be happy to talk through what is available and enable you to select, amongst others: species, profile, size, treatment, requirement for Euro Class B, service life.

We offer installation guidance, detailing guidance based on TRADA documentation, with a wealth of knowledge and information on how different timbers will perform over the life span of your project.

Considerations that should be made when it comes to weather, along with how elevation and design variations can impact timber cladding.
