TG Sheeting, short for Tongue and Groove, or sometimes TGV sheeting (where a v-groove is part of the profile), is easy to install and beautiful to look at. TG, as the name suggests, uses a hidden tongue and groove, which runs the length of each side of the board, to slot neatly together. The V-joint or beading that runs horizontally or vertically along each panel is a decorative feature which, when in place and can also act to disguise the join between each panel.
