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

Install in one day
It's simple design means that a ThermoSphere Membrane system is typically installed in just one day. Our recommended installation requires less steps than other underfloor heating products which allows you more time to just enjoy life and/or focus on your other projects.
Made for wet rooms
The advanced waterproofing properties make ThermoSphere Membrane a perfect fit for wet rooms. It can be installed on walls as well as floors and sealed against moisture by using the ThermoSphere Waterproofing Kit.
Lifetime warranty
As with all our electric underfloor heating, in the unlikelihood that you do experience a problem with ThermoSphere Membrane, don't worry, you can relax knowing that it comes with a lifetime warranty.
You must register within 60 days of installation to be covered by the warranty.
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.
