Underfloor Heating Screed in Copplestone — 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 Copplestone 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.

Common Copplestone 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.
When can I switch the underfloor heating on in Copplestone?+
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 Copplestone 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.
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.
How does this affect my floor coverings in Copplestone?+
Once commissioned and the floor moisture content is signed off (CM test, typically below 0.5% for tile), most coverings go down as normal. We hand you a commissioning record.
Copplestone jobs reward proper site prep. We'll spec the build-up with your UFH installer, agree the pour window, and leave you a floor your tilers will thank us for.
