Mike England Timber Cladding Solutions
Western Red Cedar (WRC)
We offer cladding in WRC No.2 Clear & Better with PEFC™ certification. WRC is naturally resistant to decay and insect attack and has a class 2 durability rating giving a service life of approximately 60 years untreated. When left untreated and exposed to sunlight and UV degradation, cedar will bleach to a particularly lustrous silver grey colour. Other properties include a low shrinkage factor which minimises any potential warping, twisting & checking making the finished product extremely stable.
WRC offers superior acoustic qualities to assist with noise reduction, its low density and high proportion of air space makes it a natural thermal insulator far superior to other building materials such as brick, concrete and steel. These properties allow WRC cladded buildings to remain cool in summer and reduce heating costs during the winter.
The cladding can be coated on our dedicated line with a specially formulated clear lacquer which will reduce the silvering process and greatly increase its ability to repel water. Although this coating is not warranted (most major paint manufactures will not warrant external cladding) the product has been tried and tested to maintain WRC natural colour for as long as possible.
Thermowood is produced by a complex heat treating process on selected Scandinavian pine which changes the timber properties from a none durable timber into a class 2 durability rated BN EN 350 product. The treated timber can be sawn, machined or trimmed to length in the normal way without the need for retreating.
This system enhances the properties of the timber providing many benefits which include greater stability. The timber darkens to an attractive brown turning to a silvery grey with weathering over a period of time.

MET offers slow grown Siberian Larch with FSC® certification. Siberian Larch is slightly more dense and is a straight grained material having less knots than Larch sourced from other Countries.
Siberian Larch is a very strong and robust timber, resistant to rot and fungal attack with good durability properties making it an ideal timber for exterior use such as cladding. Siberian larch is an excellent timber cladding, which over time and left untreated will change colour to a silver-grey when exposed to sunlight. Siberian Larch has a high wear resistance, is non-corrosive and doesn’t need a preservative treatment due to its durability.
Siberian Larch is between 470Kg/m3 /650kg/M3 at 12% moisture content, and has a higher impact resistance to Western Red Cedar. Durability is class 3 moderately durable and if sapwood is excluded can be used as an exterior cladding untreated. Stability is generally good, however if sapwood is present larch can be susceptible to movement.
A/B Grade – acceptable grading rules include, tighter inter-grown knots approx. up to 40mm in diameter, sound spike knots no longer than half the width of the board are also acceptable. Bark and resin pockets are allowed up to 2cm of the surface area and two pieces per board, 2 shakes in a width of 1mm in a length of 10% of the board.
Durability: Moderately durable. Hard dense timber 470g/m 650kg m3
Moister content: 18% to 20%
Storage advice: Kiln dried to be kept under cover, green can be kept outside
This species offers the most cost effective timber cladding solution. MET have worked closely with several Swedish and Finish mills since 1969, securing the best Scandinavian timber FSC® or PEFC™ certified, slow grown to the highest standard.
This proves to be an ideal timber for Cladding and can be supplied with a Sikkens Factory Coating to enhance the durability, which is widely used throughout the leisure industry. Redwood provides an excellent base for coating, however knots present in the timber can cause imperfections so only higher grades are used providing a smooth clean finish, ideal for external cladding.

The timber should be kept under cover in a dry place. Factory coated cladding should be stored in the same way until fitted, since the coatings are micro porous and will take in moisture. If laid flat in wet weather and in extreme heat knots will naturally bleed sap which is best left to crystalize before cleaning off.
