A considered library — specified, not stocked.
The systems, materials and controls we specify across MJP projects — with the full manufacturer data sheets hosted below for architects, M&E consultants and contractors to download.
Pipework, manifolds & build-up components.
Our underfloor heating product library is curated and refined continuously — selected on technical fit, not commercial habit. Components are specified per project to match heat source, floor type and architectural intent.
Flow-balanced, pre-assembled manifolds with isolation valves, flow meters and actuator heads. Sized for two-port to fourteen-port configurations.
Oxygen-barrier PE-Xa pipework in 12, 16 and 20 mm — laid in screed, between joists or in floating-floor channels.
Aluminium plates engineered to spread pipework heat evenly across timber and floating floor systems.
PIR and EPS panels — including pre-grooved channelled variants for floating floor installations.

Discreet, intelligent, calm.
Years of customer review and field tuning have refined our controls library into a set of products that perform across every UFH scenario — from a single bathroom retrofit to a whole-home heat-pump installation.
Discreet wall-mounted controls in brushed brass or muted neutrals — per-room programming with PID temperature logic.
Battery-powered thermostats for retrofit installations where chasing in cabling is undesirable.
Per-room scheduling, geofencing and integration with the home's wider smart systems.
Modular wiring centres paired with thermal actuator heads — engineered for whole-home zoning.
Liquid and traditional — specified per project.
We work across all major liquid screed systems, and we still install traditional sand & cement where it is the right answer. The choice is led by the build-up, the finish, the programme and the heat source — never by what's easiest to pour.
- CemfloorCementitious flowing screed with excellent thermal conductivity and minimal shrinkage. Specified beneath natural stone and large-format porcelain.
- Gyvlon (Thermio+)Calcium sulphate flowing screed — fast surface regularity, high conductivity and excellent compatibility with low-temperature UFH.
- Tarmac Topflow Screed CCementitious flowing screed engineered for high-performance underfloor heating installations and low-depth pours.
- GypsolGypsum-based flowing screed for low-depth pours — ideal for retrofits and extensions.
- LongfloorCementitious flowing screed with rapid drying for time-sensitive programmes.
- Traditional Sand & CementProven hand-laid screed — still the right specification for certain projects, contractors and substrates.
The full technical library — open access.
Every product specified across MJP installations, with its manufacturer data sheet hosted here for download. Architects, M&E consultants and contractors can specify ahead of tender without needing to chase paperwork.
Full handover packs — including commissioning records, leak tests and flushing certificates — are issued per plot on completion.
