Installation systems for Thermory decking

You’ve selected the perfect decking for your outdoor space – now you just need to decide how best to secure it in its chosen location. There are two main types of fixing that we offer, visible and hidden. With several options available for Thermory products, we’ve created a short introduction to the various fixing methods you can choose from when installing your decking.

Hidden fixing options

Hidden fixing is great if you want to achieve neat-looking decking with a clean surface.

PaCS® Powered by Grad – Press and Click System

Thermory PaCS® Strip is an innovative fastening solution with pre-grooved boards that enable a quick and easy deck installation with no visible screw heads and automatic alignment with a gap of 5 mm between the boards and underconstruction beams to ensure good ventilation. The strips, which fit together end to end, each consist of six clips that allow three boards to be attached sideways onto a single joist by simply securing the strips and then clicking the boards into place. PaCS is available with Thermory Ash and Thermory Pine decking.

Estimated use is 7,5 strip clips per m2. End-user package contains 30 strip clips, 4.0x30mm stainless steel screws and a drill bit.
