SIBERIAN LARCH CLADDING

Larix decidua

Millworks Siberian Larch Cladding is sourced from old-growth, slow grown logs, plentiful in the vast forest region of Northern Europe. This cold, harsh climate gives Siberian Larch some fantastic natural attributes, making it a popular choice on many building projects.

PROFILES

Contemporary

Siberian Larch has colour tones from pale reddish-brown to golden brown. Once weathered the colour will be a subtle grey. Straight grained, with tight annual rings and relatively few knots, give an attractive contemporary look.

Versatility

Siberian Larch is very dense at 590kg per m3. This characteristic makes it hard wearing, perfect for exposed elevations or high traffic areas. Suited to commercial projects, or residential alike.

Durability

Siberian Larch has a maintenance free service life, due to natural resin and extracts in the wood. The high density makes it one of the toughest and most durable softwoods available. Siberian Larch is BS EN 350-2 Class 3.

Stability

Siberian Larch is dimensionally stable due to controlled kiln drying at source, making the moisture content optimum for its intended environment, which also achieves a superior finish when machined.

Grades

  • Millworks Grade A  (Unsorted)

This grade of Siberian Larch is of the highest quality available. Limited knots and hand selected which offers a clean, consistent look.

As classified by BS1186:3 Class 1

  • Millworks Grade B (Sawfalling)

This grade of Siberian Larch allows for larger knots, yet no compromise on durability and is well suited to timber cladding.

As classified by BS1186:3 Class 2

Weathering or finishing

In the correct conditions, Siberian Larch will weather to a silver-grey, if left untreated.
Although naturally durable, Larch can be finished for protection against the elements. This will keep it looking consistent on all elevations of your project. Millworks can advise on different options for protecting your timber.

Coatings can be applied under controlled factory conditions with Millworks state of the art finishing line. Alternatively, on-site products can be advised and supplied.

Off-site (factory applied) coatings

  • Flawless finish under factory conditions for outstanding UV protection.

  • Wide range of colours available.

  • Coating to all 4 sides for increased durability and stability.

On-site (hand applied) coatings

  • On-site weather variation, time-frames and application rate eliminated.

  • Lead-times are not guaranteed due to on-site variables.

  • Unexpected hidden costs

Fire Retardant for Timber

FRX Exterior fire retardant can be applied to Siberian Larch cladding when specified, to comply with national Building Regulations where Euroclass B or C are required. Applied under controlled conditions in a vacuum pressure timber impregnation plant. The treatment complies with ISO accreditation, which does not compromise critical properties such as strength, durability, corrosivity and hygroscopicity.

Alternatively, HR-Prof can be applied on site, a fire retardant that complies with Euroclass B or C for spread of flame, offering a quicker and sometimes cheaper option.

Fixings

Stainless-steel cladding fixings should be used because natural oils in the timber have a corrosive effect on ferrous metals.
