Underfloor Heating Screed in Alphington — how it works
Liquid UFH screed lets you run a thinner build-up than traditional bays — useful when ceiling heights or threshold levels are tight in Alphington renovations.
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.
Specifications suited to Alphington 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.

Common Alphington build questions
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 Alphington?+
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 Alphington 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.
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.
Do you fit the UFH pipes yourself?+
We work alongside your chosen UFH installer rather than fitting pipes ourselves — most Alphington jobs come with a heating sub-contractor already lined up, and we coordinate dates with them.
