MATERIALS FOR INSTALLATIONS BY MEANS OF FIXING RAILS OR HAMMER CLIPS

Floor heating pipes can directly be fixed on the subfloor by means of a rail system or plastic hammer clips. This is most commonly done when new screed is poured (such as in new constructions or renovations).
Depending on the available installation height, the rail system can also be used to mount heating pipes on insulation.

 

Adhesive flooring screed

When making use of this way of installing underfloor heating, the pipes are mounted by means of the rail system or hammer clips without additional insulation or reflective foil. Screed will therefore be poured on the (existing) structural subfloor, creating adhesive flooring screed.
 

Floating flooring screed

Before the fixing rails are put in place, (Tacker) insulation is laid over the entire floor. The fixing rail on which the heating pipes will be mounted is placed on top of insulation by means of plastic clips. This method of installation creates a floating screed which will allow the floor to expand and shrink independantly from the structural subfloor.
In order to minimise unwanted heat loss and allow for expansion, it is important to ensure that the floor screed does not form a bridge to either external or internal walls. Therefore, edge insulation must be placed against all walls.
