Biscuit Mix

Biscuit option for Joisted underfloor heating systems

Biscuit Mix Option – Underfloor Heating Systems

The biscuit mix gives the floor extra thermal mass; reduces expansion and contraction noises

This option is normally considered when aluminium spreader plates are difficult to install and/or will not deliver required output.

Biscuit option joisted UFH

JOISTED FLOOR HEATING – BISCUIT MIX OPTION

 

An option to consider when installing underfloor heating between joists where additional thermal mass can be achieved it to lay a dry biscuit mix between joists around heating pipe work.

 

This option is normally considered when aluminium spreader plates are difficult to install and/or will not deliver required output.

 

Under floor heating pipework on first or timber floors should be fixed to insulation between joists in suitable spacing or channels based on outputs required and heat source. Timber sub floors can be laid after installation of under floor pipe work and a wooden floor should not exceed 22mm in total thickness.

 

It is often feasible to lay a biscuit mix of sand and cement (8:1) around the pipes and between the joists level to underside of floor finish.

 

The biscuit mix gives the floor extra thermal mass; reduces expansion and contraction noises that can be experienced as the floor cools and warms during the heating cycles and improves the overall output and performance of your floor heating system.

 

NB. PIPES WOULD BE AT 150mm or 100mm CENTRES FOR HEAT PUMP

 

Please consider the addition weight that will be placed upon the supporting joists and ensure that the subfloor support structure is adequate to support the additional mass of circa 20kg/m2
