HÖRSTAD Diffuser Plate 390x1000mm (150 or 200mm spacing) 2 groove for 16mm pipe

Diffuser plates specifically designed for joisted floor constructions. Before the underfloor heating system is installed, mineral wool/fibre insulation, typically a minimum of 100mm, should be laid between the joists. It is important that the insulation layer is pushed up tight to the underside of the plates to maximise heat output. The diffuser plates are then fixed to either side of the joist void and can be laid on straight pipe runs which typically covers 80% of the heated floor area.
