Exterior Tongue and Groove Cladding
What is Tongue and Groove Cladding?
Tongue and groove or T&G is a machined profile supplied with a smooth finish and an interlocking edge detail that creates a clean, waterproof facade. Tongue and groove wall cladding offers a linear appearance, ideal for contemporary new builds and modern extensions. A key benefit of tongue and groove cladding boards is the ability to hide fixings through the tongue, delivering a seamless finish.

Installation
How to fix
VTG1, VTG2: Face-fix only (one fixing per board/batten).
VTG3, VTG4A, VTG5A, VTG6: hidden nail or face-fix (one fixing per board/batten).
Leave a 2 mm expansion gap between each board.
Horizontal attachment
Begin at the bottom, ensuring the first board is level. Position with the tongue edge facing upward. Use a spacer to maintain a 2 mm expansion gap between boards. Fix each board with a single nail at every batten point. Join consecutive board ends over a batten. VTG1 and VTG2 must be face-fixed, while VTG3-VTG6 can be nailed either through the face or diagonally through the tongue for hidden fixings.
Vertical attachment
Start at one corner with the tongue facing away, ensuring the first board is vertical. Nail as per horizontal installation.
Recommended battens for tongue and groove cladding
Profiled Thermowood or treated softwood battens are recommended for use behind T&G cladding.
The minimum thickness of primary battens should be 40mm. Horizontal battens to have an angled top face to shed water.

Batten spacing for external timber cladding
400 – 500mm
Fixings for tongue & groove cladding boards
Only use stainless steel fixings for external cladding.
For fixing T&G cladding we recommend 50mm ring shank nails or trim head screws for face fixing and 40mm for secret fixing through the tongue.
For stable timber species including Brimstone and cedar we also recommend two stainless steel 50mm 16 gauge second fix brads. Insert the brads at opposing angles, one hidden through the tongue and one through the face.
When to fix
Year-round, ideally between September and March.
