ThermoSphere Self-Adhesive Decoupling Membrane

Protect Tiled Floors from Movement and Cracking

ThermoSphere Self-Adhesive Decoupling Membrane provides a reliable solution for protecting tiled floors from cracking caused by lateral movement within the subfloor.

The membrane creates a decoupling layer between the substrate and tiled surface, helping to isolate movement before it can transfer through to the finished tiles. Its self-adhesive backing also makes installation quick and straightforward, without the need for an additional adhesive beneath the membrane.

Available in 1m² and 15m² options, allowing you to choose the most suitable coverage for your project.

Fast Self-Adhesive Installation

The pressure-sensitive self-adhesive backing allows the membrane to be applied directly to a suitably prepared substrate.

This provides several installation benefits:

• No separate adhesive required beneath the membrane
• Quick and clean installation
• Easy positioning and cutting
• Suitable for small areas and larger floor installations
• Creates a consistent surface ready for tiling

Always ensure the substrate is clean, stable and suitably prepared before installation.

Helps Protect Tiles from Cracking

Movement within timber, concrete and screeded subfloors can place stress on rigid tiled finishes.

ThermoSphere Decoupling Membrane helps isolate this movement from the tiled surface, reducing the risk of stresses within the substrate transferring through to the tiles.

This makes it particularly useful for tiled installations where additional protection and floor stability are required.

Suitable for Underfloor Heating

ThermoSphere Self-Adhesive Decoupling Membrane can be incorporated into suitable electric underfloor heating installations, providing a practical combination of floor protection and heating-system compatibility.

Its slim 1.8mm profile helps minimise additional floor build-up while providing the required decoupling layer.
