ThermoSphere Decoupling Membrane

Reliable Protection for Tiled Floors

ThermoSphere Decoupling Membrane helps protect tiled floors from cracking caused by movement within the subfloor. By creating a separating layer between the substrate and finished tiles, the membrane helps prevent stresses and lateral movement in the subfloor from transferring directly through to the tiled surface.

Available in 1m², 5m² and 15m² coverage options, it provides a practical solution for everything from small areas and repairs to complete room installations.

Unlike the ThermoSphere Self-Adhesive Decoupling Membrane, this version is installed using a suitable flexible tile adhesive, allowing the membrane to be positioned securely over the prepared substrate.

Helps Protect Tiles from Cracking

Changes and movement within timber, concrete and screeded subfloors can create stresses that may eventually result in cracked tiles or grout.

ThermoSphere Decoupling Membrane creates a protective layer between the substrate and tiled finish, helping accommodate movement and reduce the risk of it being transferred through to the tiles.

This makes it particularly useful in tiled areas where additional protection and floor stability are required.

Suitable for Underfloor Heating

ThermoSphere Decoupling Membrane is suitable for use as part of compatible underfloor heating installations.

Its 3mm profile provides effective decoupling while keeping additional floor build-up relatively low.

When correctly incorporated into the floor construction, the membrane provides additional protection for the tiled finish without preventing the underfloor heating system from delivering heat through the floor.

Choose Your Coverage Area

ThermoSphere Decoupling Membrane is available in three convenient sizes:

1m²
Ideal for small areas, repairs or installations requiring a limited amount of membrane.

5m²
Suitable for smaller bathrooms, kitchens and other compact tiled areas.

15m²
A convenient option for larger rooms and complete floor installations.

Select your required Coverage Area from the options above.

Flexible Adhesive Installation

This is a non-self-adhesive decoupling membrane and should be installed using a suitable flexible tile adhesive.

The membrane can be cut to suit the room layout and positioned over an appropriately prepared substrate before the finished tiled floor is installed.

Always follow the manufacturer’s installation requirements and ensure the substrate is clean, stable and suitable for tiling.
