    TG&V cladding

    Tongue & groove cladding

    Jointed sweet chestnut TG&V | VTG4

    TG&V is shorthand for ‘tongue and groove with a v-joint’. TG&V cladding is a machined profile supplied with a smooth finish and an interlocking edge detail to create a waterproof façade. The TG&V profile creates a clean linear appearance which is ideal for contemporary new-builds and modern extensions to older properties. TG&V cladding is most commonly fixed horizontally although it can be fixed vertically.

    Our standard range of TG&V profiles offers a choice of joint details to suit specific design requirements. Alternatively we can produce bespoke profiles to customer specifications.

    All air-dried species can be machined to TG&V. The most popular choices are Siberian larch and Canadian western red cedar.
