25mm Ultra-Warm Tile Direct Insulated Panel System - 70m² (150mm Centres)
The 25mm Ultra-Warm Tile Direct Insulated Panel System - 70m² is specified for substantial solid floor zones where controlled heat delivery beneath tile finishes is essential. Featuring 25mm of insulation and panel channels routed at 150mm centres, this system is supplied as a complete solution tailored for professional installation on solid substrates. It supports effective thermal performance while helping reduce unwanted heat loss into the floor structure.
This 70m² underfloor heating package includes the key components required for trade-grade applications:
- 25mm insulated panels prepared for direct tile application with a 5mm layer of self-levelling compound underneath
- Pre-routed channels at 150mm spacing to ensure accurate pipe layout
- 16mm underfloor heating pipework cut to suit 70m² coverage
- Fixings and installation accessories for secure placement
- Suitable for large open-plan areas, kitchens, and main living spaces
- Designed to promote consistent surface temperatures through tiled finishes
The 25mm Ultra-Warm Tile Direct Insulated Panel System - 70m² delivers an underfloor heating solution configured for solid tiled floors. With insulation, panel routing, and pipework engineered to function together, this system supports reliable heat distribution and an organised installation process across larger areas.

-- Remove all contaminants, dirt, grease etc from the substrate and make dust free.
-- Loose lay the boards across the floor and number the boards on the upper face to identify position of each board, making sure the pipework runs are calculated correctly to reach manifold position.
-- Uplift the numbered boards and prime the underside of the boards with Ultra Floor Prime-IT MSP bonding primer. This should be applied by brush or roller in a thin film. Allow to thoroughly dry to a clear green film ensuring primed face does not come into contact with other boards, walls or subfloor until it is ready to be bedded.
- -Drying time will depend upon ambient conditions but is typically between 1 and 4 hours.
-- Whilst the primer on the boards is drying commence with priming of the substrate using UltraFloor Prime-IT MSP. The primer should be diluted 3 parts water to 1 part primer and allowed to fully dry.
-- Apply flexible tile adhesive to the subfloor using a notched trowel to give a minimum 3mm adhesive bed. Bed the boards, primed side down, into the adhesive and ensure compression of adhesive ridges, ensure full compression of the adhesive to give a void free full adhesive bed. Additional use of screws and washers is recommended over timber substrates where needed, fixed at every 300mm. Allow to cure for approximately 4 hours to ensure the adhesive has gone through its initial set before carrying out any further works.
-- Pipe work may be fitted into the boards once they are all secure. Where possible this is best left until the following day. It is recommended that the pipe system is checked for leaks and correct water pressures prior to tiling over.
-- Prime the upper face of the boards with Ultra Prime-IT MSP bonding primer. This should be applied by brush or roller in a thin film. Allow to thoroughly dry to a clear green film, (approx 1-4 hours).
-- Apply Ultra Floor Level-iT 2 two part smoothing compound over entire floor area, making sure all voids and gaps are completely filled, the levelling compound should encapsulate the whole floor and cover the board with a 5mm layer on top.
-- Allow to cure for 24 hours prior to carrying out any tiling. Cold and/or humid atmospheres will delay the curing of Level-iT 2 so allowances should be made accordingly.
-- Prime the cured Level-iT 2 using Ultra Floor Prime-IT MSP diluted with 3 parts water to 1 part primer. Allow to thoroughly dry.
