Both are based on infrared carbon technology, but each is optimized for different floor structures and project requirements. The following overview gives you all key information needed to choose the right system.

What Both Systems Have in Common

Both TRIVOLT ONE and EVO heating films share these core benefits:

• Infrared carbon technology – even, radiant heat over the entire surface, without cold spots

• Ultra-thin construction – minimal impact on floor height and building structure

• Long service life – designed for a lifespan of over 50 years with correct installation

• Maintenance-free – no moving parts, no servicing, no filters

• Silent and invisible – completely hidden under the floor, no radiators or visible heaters

• Healthy indoor climate – reduced air circulation, less dust movement, lower mold risk

• Zero local CO₂ emissions – ideal for low-energy and sustainable buildings

TRIVOLT Heating Film ONE

Flexible, Ultra-Slim Solution for Floating Floors

TRIVOLT ONE is designed as a thin, reinforced heating film for direct installation mainly under:

• Floating laminate floors

• Floating wooden floors

• Fermacell or similar dry screed boards

Key Characteristics

• Slim profile around 0.38 mm – ideal where every millimeter of floor height matters

• Reinforced structure – resistant to mechanical stress during installation

• Fast heat response – warms up quickly, ideal for living rooms, bedrooms, and daily-use spaces

• Optimized for renovations – especially suitable in projects where wet screed is not desired

Typical Applications

• Apartments and houses after thermal modernization

• Renovation of existing floors without major construction work

• Attics, wooden structures, and lightweight floor systems

• Mobile homes, modular buildings, and prefabricated units

Because TRIVOLT ONE is installed directly under floating floors, it offers very responsive heating, making it perfect as both a primary heating system in well-insulated buildings or as comfort heating in selected rooms.

Installation Concept (High-Level)

• Installed on a prepared, level, and insulated subfloor

• Laid in strips according to a pre-designed plan

• Connected to room thermostats or a smart central controller

• Covered by a suitable floating floor (laminate, engineered wood, etc.)

From the customer’s point of view, TRIVOLT ONE provides:

• Quick installation in renovation projects

• No visible components in the room

• Pleasant, evenly warm floor surface every day

TRIVOLT Heating Film EVO

Robust Premium Film for Screed and Demanding Applications

TRIVOLT EVO is the premium carbon heating film with a slightly thicker and more robust construction, typically around 0.45 mm. It is engineered for:

• Installation under screed

• Use under vinyl, SPC, or glued wooden floors

• Environments with higher mechanical load during construction

Key Characteristics

• Robust multilayer structure – reinforced top layer for maximum durability

• Designed for high-stress environments – ideal under screed or rigid floor systems

• Stable long-term performance – excellent resistance to compression and building movements

• Universal use – suitable for a wide range of residential and light commercial applications

Typical Applications

• New-build low-energy houses with screed floors

• High-traffic areas (hallways, kitchens, living zones)

• Floors where vinyl, SPC, or glued wooden coverings are planned

• Projects aiming for completely invisible primary heating integrated in the floor structure

TRIVOLT EVO is especially recommended wherever long-term structural stability and maximum lifetime are a priority – for example in new build projects where the heating system should reliably last for decades without access.

Installation Concept (High-Level)

• Laid on a prepared, dry, and insulated base layer

• Covered by a suitable separation and protection layer (as per design)

• Embedded under screed or under floor systems approved for floor heating

• Controlled by room thermostats or a central smart system

For the end customer, TRIVOLT EVO offers:

• A highly robust, “fit-and-forget” heating solution

• Excellent comfort with smooth, even heat

• Future-proof integration for modern, energy-efficient homes

Comparison: TRIVOLT ONE vs. TRIVOLT EVO

Which Heating Film Is Right for You?

Choose TRIVOLT Heating Film ONE if:

• You are renovating an existing home or apartment

• You prefer dry construction (floating floors, Fermacell)

• Floor height is limited and every millimeter counts

• You want fast heat response and simple integration into existing spaces

Choose TRIVOLT Heating Film EVO if:

• You are building a new low-energy or passive house

• Floors will be made with screed, vinyl, SPC, or glued wood

• You require maximum robustness and long-term stability

• You want a fully integrated, invisible primary heating system designed to last for decades

Conclusion

Both TRIVOLT ONE and TRIVOLT EVO deliver:

• Comfortable, uniform underfloor heating

• High energy efficiency thanks to infrared technology

• Maintenance-free operation and extremely long service life

The key difference lies mainly in the floor structure and project type:

• ONE is the specialist for renovations and dry systems with floating floors.

• EVO is the premium choice for screed-based and robust new-build installations.

Choose the film that matches your floor type, construction method, and project stage—and in both cases, you gain a modern, silent, and invisible heating system that provides long-lasting comfort and supports energy-efficient living.
