Top 3 installation tips for Ultimate® 

1x1m sheets

In smaller areas use 1x1m ThermoSphere Membrane panels. They are smaller, lighter and easier to work with than the 15x1m rolls.

Use a roller

Use a wallpaper seam roller or soft tiling float to push the cables into the membrane channels. Your thumbs will thank you!

Cable care

Roll short lengths of cable out ahead of you on the floor and push it into the membrane in sections to make de-spooling easy and tangle free.
