Holy Trinity Church – Installation and Timelapse

April 19, 2021

A recent project undertaken in conjunction with Conservation Architects of Wantage and Classic Builders of Chalgrove. A combination of floor levelling using our dry slate compound together with Glapor glass aggregate ensured a swift delivery of this project by completely removing the drying-out time that would otherwise have been associated with limecrete or a traditional pipe-in-screed system.

Further information about our ecclesiastical work at our dedicated website Church Underfloor Heating.

The JUPITER system was specified for this beautiful church, constructed during the 12th and 13th Centuries. This picturesque church has been used as a backdrop for the television detective series Midsomer Murders, Miss Marple, as well as the 2002 film, The Four Feathers.

The interior is pictured shortly before and after the strip-out work had been completed by Classic Builders.

The floor was first levelled, using our dehydrated floor levelling slate. Our slate binds together under loading, and so to keep it pinned firmly in-situ. JUPITER installed a layer of Fermacell 2E11. Fermacell boards are non-organic and so will not rot as a layer of plywood might, they are also approximately twice as heavy at 23 kg / m².

Pictured immediately above, our high compressive strength 30 mm thick Ideal EPS heating panels are installed on top of a layer of Kingspan Styrozone insulation, on top of the Fermacell boards. These feature rigid aluminium plates that rapidly and evenly diffuse the heat across the floor.

Our unique, tongue-and-groove Screed Replacement Tile (SRT) is installed on a slip membrane over the heating panels. The SRT system is bonded together, but not down, forming an inherently decoupled floor that is just as strong as 65 mm thick sand and cement screed. No expansion or movement joints are necessary as the SRT system expands and contracts absolutely minimally across its normal range of operating temperatures.

JUPITER formed a ramp using our dehydrated levelling slate and the Screed Replacement Tile system. Our complete manifold installation, incorporating a blending valve and circulation pimp is visible on the upper level.

Our tightest pipe centres (125 mm centre-to-centre) were used throughout the project to ensure the highest output available was achieved. The size of the footprint to be heated necessitated four manifolds in total.
