These boards are machined from quality kiln dried redwood timber and left untreated for interior use. The TGV profile boards are designed so that each one interlocks with the adjoining boards while still allowing movement of timber with any changes in moisture conditions, e.g. kitchen or conservatory.
The smaller TGV boards are ex 16mm x 100mm and finish at 11mm thick with a cover of 84mm. Board lengths vary from pack to pack but normally we aim to keep lengths at, or near, 3.6 metres (approx. 12′) and 4.8 metres (approx. 16′) in stock. TGV boards are still very popular for cladding interior walls and stud partitions, ceilings and roof joists, making doors and cupboards and bookcases. Sometimes these timbers are available in 3.9m or 5.1 metres
Although the timber is kiln dried it is still good practice to let the timber “condition” in the property, preferably the same room, for 7-14 days before it is fixed into place. All wet trades should be finished and the plaster in the rooms must be thoroughly dried out. Traditionally TGV cladding is secret nailed with panel pins or very small ovals or lost head nails taking care not to split the tongues.
When the untreated TGV timber is first fixed it will almost certainly be very light in colour, a very pale creamy colour. However, as the timber becomes exposed to light the timbers colour will darken to a light brown. By applying Osmo ‘Raw’ or Treatex ‘Natural’ Hardwax oil will help to keep the timber colour similar to the shade when it was originally supplied
