Liquid UFH screed in Whimple 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 Whimple jobs sit within 30 minutes of base, so site visits stay simple and pour days run to time. Whimple sits Exeter (8 mi), and we work the surrounding villages on the same week's diary.

Underfloor Heating Screed in Whimple — 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 Whimple 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.
Who this is for in Whimple
Whimple sits rural — barn conversions, self-builds, agricultural sheds, equestrian floors. Access is usually fine, but power and water on site need confirming up front. We do that at the site visit.

FAQs from Whimple clients
When can I switch the underfloor heating on in Whimple?+
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 Whimple 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.
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.
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.
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.
Do you fit the UFH pipes yourself?+
We work alongside your chosen UFH installer rather than fitting pipes ourselves — most Whimple jobs come with a heating sub-contractor already lined up, and we coordinate dates with them.
