Underfloor Heating Diffuser Plates Systems

Aluminium heat diffuser plates, used as an integral part of a warm-water underfloor heating system, help spread heat evenly and quickly, whilst increasing heat outputs and improving system response times.

The Profix® PLUS Pipe in Diffuser Plates System is a ‘dry-fit’ floor heating solution in which specially designed Profix® PLUS Aluminium Heat Diffuser Plates fit neatly onto the Profix® PLUS Panels. The underfloor heating pipework then simply clips into the aluminium plates, optimising heat transfer, followed by either T & G Flooring Grade Chipboard (or similar), or more thermally conductive T & G Dry Screed Replacement Boards, onto which the final floor covering is laid.

To see how the Profix® PLUS Pipe in Diffuser Plates System can be used to create a low-profile, dry-fit, enhanced heat output, fast response warm-water floor heating solution, check out the video below.

Increased Heat Output

Aluminium Heat Diffuser Plates are a great addition to warm-water underfloor heating systems, helping to spread the heat  evenly and quickly, as well as  helping to achieve increased  heat outputs.

Due to the unique design of the Profix® PLUS Panel  combined with that of the purpose-made Profix® PLUS aluminium heat diffuser plate, the plates fit directly onto the panels and the pipe then simply clips securely into the plates. This results in a high performance, dry-fit, fast-fix  solution for either floor heating or wall heating applications.

Floor Coverings

The high structural integrity of the Profix® PLUS Panels enables either T & G flooring grade chipboard (or similar) or T & G dry screed replacement boards to be laid over them as a floating floor. The Profix® PLUS Heat Diffuser Plates increase heat output and help to spread the heat more evenly and quickly. The use of more thermally conductive T & G dry screed replacement boards will further optimise heat output and enables a wide range of different final floor coverings to be applied. Tiles, luxury vinyl / linoleum, or laminate flooring can be bonded to the dry screed replacement boards for a fast and efficient installation. Alternatively, a low TOG carpet and underlay can be laid.

Tiles or Engineered Wood

When bonding Tiles or Laminate Flooring onto T & G dry screed replacement boards the surface should first be primed using a suitable acrylic dispersion primer before applying a decoupling layer and cement-based tile adhesive, or before applying laminate flooring adhesive.

Carpet or Luxury Vinyl

Low TOG Carpet & Underlay or Luxury Vinyl can be laid onto either T & G flooring grade chipboard (or similar) or T & G dry screed replacement boards. However, when laying Luxury Vinyl the surface of the boards should first be primed using a suitable acrylic dispersion primer and a thin skim-coat of Profix® Levelling Compound applied to obscure any joints and provide a completely smooth and level surface.
