When Dalwood self-builders specify UFH, the screed is what makes the system efficient. We pump Cemfloor Therm directly around your pressure-tested pipework for full encapsulation.
For Dalwood 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.
Most of our Dalwood jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Dalwood sits Honiton (5 mi), and we work the surrounding villages on the same week's diary.
Underfloor Heating Screed in Dalwood — 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 Dalwood 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.

FAQs from Dalwood clients
When can I switch the underfloor heating on in Dalwood?+
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 Dalwood clients to the schedule.
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.
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.
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 Dalwood UFH installers recommend it.
