Across Plymtree we work hand-in-hand with UFH installers — they lay and pressure-test the pipes, we pour around them the next day at the right depth and thermal performance.
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Plymtree renovations.
Most of our Plymtree jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Plymtree sits Cullompton (5 mi), and we work the surrounding villages on the same week's diary.

Underfloor Heating Screed in Plymtree — how it works
The screed self-levels around every loop, eliminating the voids you get under hand-laid traditional screed. That means the floor responds faster when the heating calls for it, and stores less wasted heat.
For Plymtree 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.

Cemfloor Therm
Liquid screed engineered for UFH — lambda 2.1 W/mK, fast response.
PIR/Phenolic insulation board
70-150mm typical depending on build regs U-value target.
Edge insulation strip
Critical around UFH zones to allow thermal expansion.
Pressure-testing kit
Pipes held at 6 bar through the pour to flag any damage immediately.

FAQs from Plymtree clients
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.
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.
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.
When can I switch the underfloor heating on in Plymtree?+
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 Plymtree clients to the schedule.
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.
Can you pour over a heat-pump system in Plymtree?+
Yes — and we'd argue you should. Heat pumps run at lower flow temperatures than gas, so the screed's thermal conductivity matters more, not less.
From the first site visit to the final laitance sand, our Plymtree jobs are run as one fixed-price piece of work — no creeping extras.
