Fixing Details

Multigroove Plank Fixing DetailExtruded aluminium rails are mounted on battens at 400mm intervals perpendicular to the narrow section of the planks.  Self-locking clips are applied that slot into the hidden grooves along the plank edges, thereby locking everything into place.

For further fixing details please see the fixing system and installation guide page.

Acoustic Test Results

All panels come with Decoustic 85 felt bonded to the back as standard. Acoustic blanket can also be provided if required. All Décortech panels are prefinished saving time and cost onsite and reducing potential issues such as spills, overspray or damage.
