Fixing TG&V cladding
Profiles: VTG1 – 5
Begin at the bottom, ensuring that the first board is level with the grooved edge facing downwards. If the width of the board is 150mm or less, it can be attached with a hidden nail diagonally through the tongue.
For widths over 150mm, the board should be face-fixed, using two fixings per board. These should be spaced 65 –75mm apart to allow for some dimensional movement.
Leave a gap of approximately 2mm between each of the subsequent boards to allow for possible expansion.
Begin at one corner with the tongue facing away, ensuring that the first board is vertical. Nail as with the horizontal attachment.
