The Cli-Mate Underfloor Heating Decoupling Membrane is a specially designed polyethylene membrane. It has rounded, square-shaped studs that form channels to hold the heating cable. A nonwoven thermo-welded polyethylene fabric on the underside ensures the membrane is securely fixed.
This new decoupling membrane offers many benefits. For example, its sturdy polyethylene construction gives it 40% higher compression resistance and 45% more tensile strength. This construction also reduces curling and rollback.
The Cli-Mate Underfloor Heating Decoupling Membrane is 5.5mm thick. It doesn’t require expansion joints in the screed before you lay ceramic and natural stone tiles. The membrane acts as a guard against subfloor movement, which can cause tiles to crack. For maximum efficiency, we recommend installing an insulation board below the decoupling membrane.
What is a Decoupling Membrane?
A decoupling membrane serves several key purposes. It protects your flooring from damage and improves the overall performance of your heating system.
Preventing Cracks and Damage Subfloors can shift over time, causing cracks in flooring. A decoupling membrane provides a barrier that absorbs these movements, preventing stress from reaching and damaging your floor.
Improving Durability By reducing stress, a decoupling membrane helps make both tiled flooring and underfloor heating systems more durable and longer lasting.
Reducing Noise Additionally, a decoupling membrane acts as a sound barrier, reducing noise transmission in your home.
Increasing Heat Distribution By creating a more stable substrate, a decoupling membrane helps ensure even heat distribution. This makes underfloor heating more efficient and effective.
Improving Tile Adhesion Finally, a decoupling membrane helps create a better bond between the tiled flooring and the substrate, improving tile adhesion.
Suitable Substrates
This membrane is suitable for various surfaces, including:
- Concrete Floors
- Timber Floors
