Compatible floating or click LVT can use an approved floating assembly, with a dry overlay where its manufacturer requires one. Bonded LVT and sheet vinyl need an approved smooth supporting construction, compatible adhesive and any specified levelling or overlay layers. Confirm the exact product and traffic load.
LVT and vinyl are not the same product
This is the distinction that gets missed, and it is the one that matters.
Floating or click LVT uses the assembly approved by its manufacturer. A dry overlay or a suitable underlay may be required for the exact product. Bonded LVT is a different construction and needs approved rigid support, levelling or overlay layers and compatible adhesive.
Sheet vinyl is a different animal. It is a safety floor, it is thinner and it is flexible, and you are sticking it down rather than floating it. Sheet vinyl is about 2mm and flexible, so it normally goes into a levelling compound over the Ribbon. In a domestic room it can go on a dry overlay board instead. Which one you use depends on how much traffic the floor takes
The thinner and floppier the product, the more it needs a solid, smooth surface underneath it, otherwise you get movement, distortion or joint failure as the floor heats and cools.
Glue-down LVT sits with sheet vinyl rather than with click LVT: it needs the smooth surface, and the adhesive has to be approved for use with underfloor heating.
Which build-up you need
| Rigid click LVT, around 5mm | Use the approved floating assembly, including a dry overlay or suitable underlay where the LVT manufacturer requires it. |
| Sheet vinyl, around 2mm | Levelling compound over the Ribbon, or a dry overlay board in a low-traffic domestic room. |
| Glue-down LVT | As sheet vinyl, and the adhesive must be underfloor heating approved. |
| What decides it | The exact flooring product, its approved construction and the expected traffic load. |
| Heating | The Ribbon at 1.8mm, taped down with EkoBuild's own high-tech tape |
| Insulation and support | Specified for the exact floating or bonded assembly. Do not assume soft Therm-All is suitable below bonded LVT, sheet vinyl or levelling compound. |
| Warm-up through the floor | Floor-dependent |
| Supplier paperwork | Supplier paperwork includes Nemko certificate P15220551, dated 3 December 2015, for AHT floor-heating elements, Class II, tested against EN 60335-1, EN 60335-2-96 and EN 62233. Ask EkoBuild for the documentation applying to the product supplied. |
The honest bit about cost
The exact LVT product, fixing method and approved floor construction determine whether an overlay or levelling layer is needed. Compare the complete flooring and fitting costs with a compatible floating laminate construction; the heat output depends on the chosen products and layers.
That is not us talking you out of LVT. It is worth knowing before you buy the flooring, because the flooring decision drives the heating build-up and not the other way round.
Temperature limits
Follow the exact flooring manufacturer’s temperature limit and installation requirements. A suitable thermostat and floor sensor must limit the floor temperature. Do not assume the heating mat automatically stays below a flooring limit: controls, floor construction and commissioning all matter.
Set and commission the floor-temperature limit from the flooring datasheet using suitable controls and a correctly positioned sensor. A setting alone does not guarantee the temperature at every point; keep heat free to escape and have faults checked.
Can it be the room's main heating?
Ribbon can provide primary heating when the usable output from the fitted mats meets the room’s calculated heat loss at the permitted floor temperature. Around 70–80% useful coverage is a planning aim, not a pass/fail test. Confirm the complete heating design before removing existing heating.
Lower coverage needs a room-specific output and heat-loss assessment; it does not automatically require an infrared panel

Underfloor heating under LVT and vinyl FAQs
Can you put underfloor heating under LVT?
Compatible LVT can be used with the approved construction for that product. Floating or click LVT may need a dry overlay or suitable underlay; bonded LVT needs an approved rigid supporting construction and compatible adhesive.
Can you put underfloor heating under sheet vinyl?
Yes. Sheet vinyl is about 2mm and flexible, so it normally goes into a levelling compound over the Ribbon. In a domestic room it can go on a dry overlay board instead. Which one you use depends on how much traffic the floor takes
What is the difference between LVT and vinyl for underfloor heating?
The fixing method and product specification decide the construction. Floating or click LVT uses its approved floating assembly; bonded LVT and sheet vinyl need an approved smooth supporting construction and compatible adhesive.
What temperature can vinyl take?
Follow the exact flooring manufacturer’s temperature limit and installation requirements. A suitable thermostat and floor sensor must limit the floor temperature. Do not assume the heating mat automatically stays below a flooring limit: controls, floor construction and commissioning all matter.
How long does it take to warm up?
Warm-up time varies with the floor construction, starting temperature, control settings and room conditions. Initial warmth at the surface is different from heating the whole room; a demonstration time is not a guaranteed result for your installation.
