Underfloor Heating With No Screed

What "no screed" actually means

Screed is the layer of sand and cement, or a liquid pour, that goes over the top of a wet underfloor heating system to hold the pipes and spread the heat. With a traditional water system you lay the pipes, pour screed over them, then wait for it to set before you can lay your floor.

"No screed" underfloor heating skips that layer. The heating goes down, your finished floor goes straight on top, and there is no wet pour in between. With the EkoBuild Ribbon there is no screed of any kind. The ribbon is 1.8mm thin, it tapes to your subfloor, and your carpet, laminate, vinyl or tile sits on top of it. That is the whole build-up.

Why avoiding screed matters

Screed is the part of an underfloor heating job that wrecks renovations. It is the reason a lot of people give up on warm floors. Here is what it brings with it:

• Floor height. Screed adds real depth to your floor. In an existing room that eats your headroom, fouls your door swings, and leaves a step between rooms.
• Drying time. Traditional screed can take weeks to dry before you can lay your floor or even heat it. Your room is out of action the whole time.
• Mess and disruption. It is a wet trade. Mixers, hoses, dust, and a room you cannot use while it cures.
• Cost. The screed itself, the labour to lay it, and often a digout to make room for it all add up fast.
• Renovation risk. Ripping up a finished floor to lay screed is a deal breaker on most retrofits. It turns a simple upgrade into a building job.

If you are renovating, working over an existing slab, or fitting a floating floor, screed is the thing standing between you and warm floors. Take it out and the whole job gets simpler.

Why most "no screed" systems are still wet

Search "underfloor heating no screed" and most of what comes back is forum threads and wet systems wearing a low-profile badge. This is the part the competitor blogs hedge on, so here is the honest version.

Most "low profile, no screed" products are still water systems. They run warm water through pipes, the same as any wet underfloor heating. To avoid a deep screed pour they sit the pipes in routed overlay panels or a thin self-levelling layer. That removes the deep digout, but it is not nothing. You are still adding a board build-up, you still have a wet trade on site, and you still need a manifold, a pump, and a heat source feeding it. "No screed" in that world really means "less screed than usual."

An electric system is a different thing entirely. There is no water, no manifold, no pump and no pour. With the ribbon the heating layer is the ribbon, full stop. That is what makes it genuinely no-screed, not low-screed.

How the EkoBuild Ribbon does no-screed electric

The ribbon is an amorphous metal ribbon, 1.8mm thin, that rolls out across your floor and tapes down to the subfloor. Your finished floor goes straight on top. No screed, no pour, no excavation, almost no change to floor height. It connects to a thermostat and runs at 150W/m².

The reason it works as a thin, no-screed layer and still heats a whole room is the element density. The ribbon has 300% more heating elements than a standard cable system. A thin electric cable spread out under a floor leaves warm stripes and cold gaps, which is why those systems get sold as a top-up. The ribbon spreads heat evenly across the floor, so it can be your main heating, not just a take-the-chill-off mat. There is more on that in our guide to electric underfloor heating as a primary heat source.

Does no screed mean less heat?

This is the worry that stops people, and the answer is no. The screed in a wet system is not magic. It is just a way of holding pipes and moving heat. Skip it and you lose the depth and the drying time, not the warmth.

The thing that actually controls how warm a no-screed floor feels, and how cheap it is to run, is insulation. Lay our Therm-All insulation under the ribbon and it pushes the heat up into the room instead of letting it soak down into a cold subfloor. The floor warms faster, holds heat better, and costs less to run. A no-screed floor with insulation under it can warm up quicker than a screeded one, because there is no thick wet mass to heat through first.

On running cost, the other thing worth knowing: once a room is up to temperature, the ribbon only draws power for about a quarter of each hour to hold it there. With insulation under it and a thermostat keeping it on a schedule, it is cheap to run. Pair it with solar panels and a battery on an off-peak tariff and your daytime heating can be close to free. EkoBuild supplies solar PV and battery storage too, so the whole setup can come from one place.

Which floors it goes under

Because there is no screed, the ribbon works under almost any floor finish:

• Carpet, including as a primary heat source, which most electric systems cannot do
• Laminate and engineered wood
• Vinyl and LVT
• Stone and tile

This is exactly where no-screed matters most. Floating floors like laminate and engineered wood do not want a wet pour under them anyway, so a thin taped-down layer is the natural fit. And carpet, which a screeded wet system would never sit happily under, runs fine over the ribbon.

How it's fitted

No screed also means no wet trade, which is why this is a job you can do yourself. You roll the ribbon out, tape it down to the subfloor with the supplied tape, and lay your floor on top. There is no pour to wait on and no digout. The only part that needs a qualified electrician is the final connection of the thermostat to your mains. Full installation guides come with every order, and you can plan the exact layout in the free Room Designer before you order.

What no-screed underfloor heating costs

Taking screed out of the job removes a whole chunk of cost: no screed material, no labour to lay it, no digout. What is left is the ribbon and the bits around it. EkoBuild pricing is simple and delivery is free across the UK:

• 0.5m Ribbon roll from £45 per square metre, for rooms with furniture and fixed runs
• 1m Ribbon roll for open floors
• Therm-All insulation to lay under the ribbon for faster warm-up and lower bills
• Complete bathroom kit with the ribbon, thermostat and insulation together

Every ribbon is backed by a 15-year warranty. Browse the full range in the shop, read the full electric underfloor heating guide, or use the Room Designer to get an exact price for your room.
