Grades

All grading information is given as general guidance, to meet the criteria set through CE/CA marking, quality and grading requirements.

European Larch timber cladding will colour down if it is not protected as soon as installation is complete with a good quality semi or fully translucent UV-radiation protective coating. It also comes in two different quality grades:

European Larch A

  • FSC® reg: C010188 Certified products available on request, sustainably sourced Timber
  • All timber is sourced and machined to CE/CA Quality Grading Requirements
  • Kiln Dried to 14-20% Moisture content
  • Typical lengths 3.0m – 5.7m
  • Average knot diameter: 40mm. Commonly referred to as Unsorted (Grade I-III)

European Larch B

  • FSC Certified, sustainably sourced Timber
  • All timber is sourced and machined to CE/CA Quality Grading Requirements
  • Kiln Dried to 14-20% Moisture content
  • Typically 4.0m lengths
  • Average knot diameter: 60mm. Commonly referred to as Sawfalling (Grade I-IV)

Treatments & Bespoke Products

Treatments

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

NORclad® Brunea provides a 30 year warranty against rot & fungal decay. The treatment process enables the timber to hold colour longer, requiring little or no maintenance

NORclad® Lite offers a 30 year warranty against rot and fungal decay. This treatment does not contain a pigment and therefore upon exposure to UV light the colour will enrich before beginning to naturally weather to a silver/ grey over time. With little or no maintenance required long term the NORclad® Lite treatment is a great peace of mind option over having untreated softwood timber cladding

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.

Specify

If you have decided that Timber Cladding is going to be one of the materials on your project the next step is to create a specification that will meet the criteria and expectations you, and your client have.

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 TDUK 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.
