EXPERTS IN MACHINED TIMBER
We import high grade machined softwood timber from the forests of northern Finland. Machined timber is an incredibly versatile product and has a wide range of applications. It is used for a variety of building projects including wooden sheds, summerhouses, panels, exterior cladding and flooring. The lengths of timber are machined to create various “profiles” which offer different properties and will determine the look of the finished shed.
As experts in machined timber we hold large stocks of weatherboard, shiplap, tongue and groove, barrel board and TGV machined profiles in a range of lengths from 3.0m to 6.0m. Machined timber can be treated with Celcure C65 in our on-site treatment plant.
BARREL BOARD / LOGLAP
Barrel Board (sometimes known as log lap) has a smooth rounded exterior profile similar to that of a log, while the interior face of the board is flat and has a planed finish. It is ideal for achieving a beautiful log effect on buildings such as summer houses, garden rooms, car ports, garages, sheds, and workshops. It is a perfect choice if you want to give your building a more rustic look and feel. Barrel Board can be treated or untreated.
Profiles available are:
-

TONGUE AND GROOVE WEATHERBOARD
Tongue & Groove (T&G) is a popular choice of machined timber and suitable for a number of applications. To make T&G, a tongue is machined on one edge and a groove machined on the opposite edge, allowing the boards to fit tightly together, excluding air and light from passing between aligned boards. The interlocking timber adds to the strength of a building and the chamfered edge aids water run-off, helping to prevent water seeping into the joints. The boards create a strong, stable, surface which can be treated, stained, varnished or painted.​
Finished sizes are:
112mm x 12mm
112mm x 14mm
112mm x 19mm
Weatherboard can be treated or untreated.

Tongue & Groove Flooring
When used indoors, Tongue and Groove is by far the most common choice of cladding. It is ideal for plain flooring or modern wall panelling. It is easier to clean and maintain as dirt cannot build up in recesses.​​
TGV Cladding
TGV is Tongue and Groove boards that have a chamfered edge on each side of the board. This creates a ‘V’ shaped recess where the boards connect which adds visual appeal to the cladding. Tongue and Groove with a v-joint is one of the most popular profiles of contemporary timber cladding because of its versatility. It can be installed vertically, horizontally or even diagonally to create a modern finish.
