Liquid UFH screed in Membury replaces the air gaps and voids that bog standard sand-and-cement leaves around pipes, lifting system response and cutting running costs.
We pour Cemfloor Therm liquid screed over your UFH pipes at 50mm above pipe (typically 65-75mm total over insulation), giving full pipe encapsulation, fast thermal response and a finished surface flat to SR1.
Most of our Membury jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Membury sits Exeter (26 mi), and we work the surrounding villages on the same week's diary.
Underfloor Heating Screed in Membury — how it works
For Membury UFH builds the typical sequence is: insulation board down, pipes clipped and pressure-tested, edge insulation in place, then we pump and level in a single visit.
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Membury renovations.

What people in Membury usually ask
Why use liquid screed over UFH rather than sand-and-cement?+
Liquid screed flows around the pipes with no voids, giving 20-30% better thermal response and lower running costs than a hand-laid screed. That's why most Membury UFH installers recommend it.
What depth of screed over UFH pipes do you recommend?+
Minimum 50mm cover above the highest pipe — usually a 65-75mm total slab over insulation. Thicker if you want more thermal mass.
When can I switch the underfloor heating on in Membury?+
On Cemfloor Therm we typically start a slow commissioning cycle from day 7, ramping 5°C per day per manufacturer spec. Forcing it earlier risks cracking, so we hold Membury clients to the schedule.
What if a pipe leaks during the pour?+
Pipes are held at 6 bar through the pour. Any pressure drop is flagged immediately and we stop, fix and continue — this is exactly why we keep the manifold under test.
Does liquid UFH screed improve EPC ratings?+
Indirectly — yes. Faster response and lower running temperatures help heat-pump COP, which feeds into your SAP/EPC. We'll share the manufacturer data your assessor needs.
Will the screed crack as the UFH heats up?+
Properly isolated at the edges and at doorway joints, no. We pour with the pipes pressure-tested and follow a controlled commissioning schedule.
