Aluminium Diffuser

ALUMINIUM DIFFUSER PLATES FOR TIMBER FLOORS

Timber floor systems rely on the conductivity of components fitted within the floor to transfer heat efficiently from the pipe surface to the underside of the floor finish.

Typically a grooved or profiled metal (usually aluminium) heat transfer sheet is provided to conduct the heat from the pipe to the floor surface, although some systems rely on other methods such as a *thin screed biscuit mix or heated airspace layer below the floor boards.

In order to achieve good results the pipes must transfer their heat evenly to the floor surface without creating sharp variations in surface temperature across the floor. This is particularly important with natural wood boarded floors so as to prevent unsightly shrinkage at any hot spots caused by inadequate heat dissipation.

Since the mass of a timber floor structure can be up to 50% less than screeded floor systems, the response time of a timber floor system is much faster than that from a solid floor system and effective control can be made simpler.

• Generally there are two types of diffuser plates
• Fit from above plates (sit between joists and are before sub floor is fitted) 1m x 390mm
• Fit from above plates are available in single, double or triple channel pipe runs
• Fit from below plates (FFB) fitted from below the floor (in ceiling space or similar) and come in double channel runs at 1m x 266mm dimensions
• Pipe spacing’s are generally 200mm but can be manufactured at closer proximity
• Ideal solution for retro fit installation in refurbishment projects
• Sizing calculation is normally heated area x 2.25 to arrive at number of plates required
