Underfloor Heating Vapour Barrier for Heating Film
The underfloor heating vapour barrier is a 100 micron polyester protective layer designed for use with compatible electric heating film and Ecofilm underfloor heating systems.
Installed above the heating film and beneath the finished floor covering, it provides an additional layer of electrical insulation while helping protect the heating system from moisture and condensation.
Each roll also includes 50 metres of fixing tape for secure installation.
Why Use a Vapour Barrier with Heating Film?
A suitable vapour barrier forms an important protective layer within compatible electric underfloor heating film installations.
It helps to:
-
Protect heating film from moisture
-
Provide additional electrical insulation
-
Create a barrier between the heating element and floor covering
-
Protect electrical heating components
-
Support long-term system reliability
-
Provide a clean protective layer above the heating film
100 Micron Polyester Construction
The vapour barrier is manufactured from durable 100 micron polyester.
Its thin construction provides protection without adding unnecessary height to the complete floor system.
The material is supplied in 1 metre wide rolls, making it easy to position across larger floor areas.
Designed for Heating Film & Ecofilm Systems
The vapour barrier is designed for use with compatible:
-
Electric underfloor heating film
-
Ecofilm heating systems
-
Infrared heating film
-
Floating floor heating systems
Always confirm compatibility with the specific heating system and finished flooring before installation.
Available Sizes
Two roll sizes are available:
12m² Roll
-
Roll dimensions: 1 m × 12 m
-
Material area: 12m²
-
Approximate installed coverage: 10m²
-
Includes 50m fixing tape
The reduced installed coverage allows for the required overlaps during installation.
25m² Roll
-
Roll dimensions: 1 m × 25 m
-
Material area: 25m²
-
Approximate installed coverage: 22m²
-
Includes 50m fixing tape
Suitable Floor Coverings
The vapour barrier can be incorporated into compatible heating film installations beneath floor finishes including:
-
Laminate flooring
-
Engineered wood flooring
-
Compatible vinyl flooring
-
Other suitable floating floor systems
Always follow the heating system and flooring manufacturer’s installation requirements.
FREE 50m Fixing Tape Included
Each vapour barrier roll is supplied with a 5 cm × 50 m roll of fixing tape.
The tape can be used during installation to secure and join the vapour barrier according to the heating system installation requirements.
Installation
The vapour barrier is installed as a protective layer above the compatible heating film and beneath the finished floor covering.
Sheets should be positioned with the appropriate overlap and securely joined according to the heating system manufacturer’s installation instructions.
Ensure the complete heating system has been correctly installed and electrically tested before the final floor covering is fitted.
