The UFH-DRY-NF XPS panels have a low build-up height and are installed without screed/chape. This ensures that the system has a fast response time due to its low thermal inertia. The panels have an aluminium layer for optimum heat dissipation. This system is installed in combination with 16mm Henco cross-linked polyethylene pipe (PEXc) and is installed in a meander pattern. The panels are available in centre distance 10cm (UFH-DRY-1625-100NF) & 15cm (UFH-DRY-1625-150NF) and always have a surface height of 25mm. We recommend laying this system in 2 phases: 1 phase for gluing the panels to the substrate and the 2nd phase for mounting the pipe. This gives the glue sufficient time to dry. To do this, follow the recommended drying time on the packaging or technical data sheet of the adhesive.
