Modern homeowners, developers and installers are looking for heating systems that are efficient, discreet and easy to install. That is why more projects across the UK are choosing Flexel EcoFilm underfloor heating.
Manufactured in Scotland by Flexel International Ltd, EcoFilm is an ultra-thin electric underfloor heating system designed for floating floors. It works perfectly beneath laminate flooring and engineered wood with only an 7mm build-up. Alternatively EcoFilm can be used under LVT, vinyl, carpet and many other flooring products with the addition of our EcoMax Duo Boards making a total maximum build-up of just 14mm.
Unlike bulky radiators or wet heating systems, EcoFilm delivers comfortable radiant warmth while remaining completely hidden beneath the finished floor. In this guide, we explain everything you need to know about Flexel EcoFilm underfloor heating.
What Is Flexel EcoFilm?
EcoFilm is a thin electric heating film that sits directly beneath floating floor finishes. The system uses advanced conductive heating technology to create gentle and even radiant heat throughout the room.
It is ideal for:
- Laminate flooring
- Engineered wood flooring
- Floating vinyl flooring
- Timber floor constructions
- Renovation projects
- New-build homes
- Apartments and extensions
Because the system has an ultra-low profile, it is perfect for projects where floor height build-up must remain minimal.
How Does Flexel EcoFilm Work?
EcoFilm converts electricity into radiant heat using conductive carbon heating elements inside the film layers. Once installed beneath the flooring, the system warms the floor surface evenly. The heated floor then radiates warmth naturally throughout the room.
Key Benefits of Radiant Heating
Unlike traditional convection heating, radiant floor heating warms people and objects directly instead of simply heating the air. As a result, rooms feel comfortable and evenly heated.
- Even room temperatures
- Fewer cold spots
- Comfortable warmth underfoot
- Silent operation
- No visible radiators
- Greater interior design freedom
Why Choose Flexel EcoFilm Underfloor Heating?
Ultra-Thin Heating System
One of the biggest advantages of EcoFilm is its minimal thickness. Therefore, it is ideal for refurbishment projects and retrofits where raising floor levels is not practical. In many cases, installers can fit the system without major structural changes. This helps reduce installation time and labour costs.
Fast and Simple Installation
EcoFilm is designed for quick installation beneath floating floor finishes. Large heating film sections cover floor areas efficiently, making the system popular with installers and developers working to tight schedules.
When combined with modern programmable thermostats, Flexel EcoFilm provides accurate temperature control and efficient energy management.
Radiant heat also feels comfortable at lower air temperatures. Therefore, users may reduce thermostat settings while still maintaining comfort levels.
Silent and Maintenance-Free Operation
EcoFilm contains no pumps, pipes, or moving parts. As a result, the system operates silently and requires very little maintenance after installation.
Where Can Flexel EcoFilm Be Installed?
EcoFilm is suitable for many modern living spaces, including:
- Open-plan homes
- Bedrooms
- Living rooms
- Loft conversions
- Garden rooms
- Apartments
- Holiday homes
- Timber frame buildings
Because the heating system remains hidden beneath the floor, homeowners enjoy complete freedom when planning room layouts and furniture placement.

Can Flexel EcoFilm Be Used as the Main Heating System?

However, suitability depends on several factors, including:
- Room heat loss calculations
- Insulation levels
- Glazing performance
- Ceiling height
- Floor construction
- Required room temperatures
Larger or poorly insulated spaces may still require supplementary heating.
