When Chudleigh 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 Chudleigh 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 Chudleigh jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Chudleigh sits Exeter (10 mi), and we work the surrounding villages on the same week's diary.

Right fit for Chudleigh homeowners and contractors alike
Chudleigh runs a healthy mix of residential renovation and small-to-medium commercial fit-out. We price both, and run both with the same fixed-price approach.
Underfloor Heating Screed in Chudleigh — how it works
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.
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.
Specifications suited to Chudleigh builds
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.
How a Chudleigh pour runs
- 1
UFH installer fits manifold, pipes and pressure-tests to 6 bar
- 2
We confirm edge insulation, DPM and pipe coverage depth
- 3
Pump and level the screed with pipes still under pressure
- 4
Slow commissioning of the heating — usually after 7 days, ramping per manufacturer spec
- 5
Floor coverings once moisture is signed off and commissioning is complete

What backs our Chudleigh work
Chudleigh screed questions, answered
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 Chudleigh UFH installers recommend it.
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.
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.
When can I switch the underfloor heating on in Chudleigh?+
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 Chudleigh clients to the schedule.
