Tanalised 19 x 100 TGV profile

Our exterior 19mm x 100mm TGV cladding is machined in the UK from quality Scandinavian redwood timber. These TGV cladding boards are popular for many exterior buildings including garden sheds, ticketing kiosks, play-houses and garden planters and storage units. The 100mm width will take more work and time to clad an area because of its smaller cover. However, the TGV boards will move less than wider boards and water ingress should be lower too.

If this TGV isn’t quite what you are looking for then check our stocks of 19mm x 125mm; 19mm x 150mm shiplap; 25 x 150mm shiplaps and a 25 x 150mm Shadowgap profile. The Shadowgap is effectively a shiplap with a sleeker, more contemporary appearance

The TGV profile allows for some board movement which occurs when timber responds to different weather conditions. If wet timber dries quickly when the sun comes out it can reduce the lap considerably. After machining the boards are pressure treated with new generation Tanalith-E preservative. This helps prevent rot and decay. Applying a waterproof timber treatment on the exterior will help maintain dimensional stability.

TGV Cladding and Timber sizes

Because our redwood TGV has a planed finish it should really be described as ex.19mm x 100mm, but the actual size after machining would be approximately 14mm x 94mm. A further consideration is that approx. 10mm will be lost in the lap. Therefore, this tanalised TGV finishes at 14mm thick and has a cover of 84mm, the technical drawing on this page explains much better than mere words. This profile can be used on a variety of buildings. Board length availability can be variable; the normal range of pack sizes is 3.6 metres up to 5.1 metres. You could also try ex.25 x 150 Tanalised T&G as well.

Carcassing sizes will largely depend on what you are constructing, many sectional sheds use no more than a 25mm x 38mm batten. Spending a little more on “2 x 2”,or “3 x 2” will not add massively to the cost. If you are cladding a building then we would recommend buying some pressure-treated corner profile, available in 2.4 metre lengths. Ideally all corner joints would have factory treated ends but this is rarely the case. To make the most of the timber you should apply end-grain preservative treatment. We sell Ronseal’s end grain preservative and they recommend two coats on any cross-cuts. You can then achieve a neater, and more weatherproof, finish by using the Corner profile as well

Tanalith, Pressure Treatment, Tanalised and the Treated-Right Warranty

The pressure treatment process helps to protect timber against decay and fungal attack. It also provides an improved service life to timbers that have only been dip-treated. Our external TGV cladding timbers are pressure treated with Tanalith E preservative, i.e. they have been “tanalised”. Our ex.19 x 100mm redwood TGV cladding is pressure treated using Next generation TANALITH E wood preservative which provides a 15 year TREATED-RIGHT Performance Warranty against wood decay and insect attack (terms and conditions apply). All crosscuts must be protected with end-grain preservative treatment. Our preference is for Ronseal Decking End Grain Protector.

Oil based micro porous wood finishes

Our redwood cladding profiles are all pressure treated and will weather to a silvery-grey finish. Because the pressure treatment is water-based it is not waterproof. Further protection should be applied depending on the product and it’s intended use. TGV used in the construction of a shed may be pressure treated but will need additional protection from moisture penetration. Apply a high-quality water-repellent paint or oil to help seal the shed, making sure that joints and fixings such as nails and screws, are well covered. A good microporous finish such as OSMO Country Colour or OSMO Natural Oil Woodstain both help control the movement of moisture through the timber surface
