1 Scope This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This document specifies uniform requirements for the design and the construction of heating and cooling floor, ceiling and wall structures to ensure that the heating/cooling systems are suited to the particular application. The requirements specified by this Standard apply only to the components of the heating/cooling systems which are part of the heating/cooling system. This document excludes all other elements which are not part of the heating/cooling system.

EN 1264-4:2009 (E) 6 4 Requirements 4.1 Floor heating and cooling systems 4.1.1 General structural preconditions The installation of a hot water floor heating and/or cooling system must follow the prior installation of any electrical, sanitary and other pipe facilities. The structure as specified in 4.1.2.1 with the draught-free closure of all building openings, e.g. windows and outer doors, must be completed. 4.1.2 Building layers, building components 4.1.2.1 Supporting base The supporting base shall be prepared in accordance with relevant standards. Any pipe work or conduits shall be fixed and encased to provide a level base upon which thermal insulation and/or acoustic insulation is added before laying the heating pipes. In this respect, the necessary structural height shall be taken into account. In the case of service pipes installed within the insulation layer, these pipes must be protected against temperature change in accordance with National Regulations. 4.1.2.2 Insulating layers, perimeter insulating strip 4.1.2.2.1 Insulating layers The resistance Rλ,ins of the insulating layer of the heating/cooling system is specified in Table 1. These requirements are for heating and cooling systems, but for cooling only systems, these values are recommended.

When installing the system-insulating layer, the insulating panels shall be butted tightly together. Multiple insulating layers shall be staggered or placed in such a way that the joints between panels of one layer are out of line with the next layer. SIST EN 1264-4:2009



EN 1264-4:2009 (E) 7 4.1.2.2.2 Peripheral insulating strip Prior to the laying of the screed, a peripheral insulating strip (edge joint) shall be placed along the walls and other building components penetrating the screed and firmly secured to the supporting base, e.g. door frames, pillars and risers. The peripheral insulating strip shall rise from the supporting base up to the surface of the finished floor and permit a movement of the screed of at least 5 mm. In the case of multiple insulating layers, the peripheral insulating strip shall be placed prior to application of the upper insulating layer. When laying the screed, the peripheral insulating strip shall be secured against any change in position. The top part of the peripheral insulating strip which rises over the finished floor shall not be cut off until completion of the floor covering and, in the case of textile and plastic coverings, hardening of the filler. 4.1.2.3 Protective layer Prior to laying the screed, the insulation layer shall be covered with a protective layer consisting of a polyethylene film of at least 0,15 mm thickness, with a minimum of 80 mm overlaps, or with another product of equivalent function. In accordance with 4.1.2.2.2, the protective layer shall be turned pulled up above the upper edge of the peripheral insulating strip unless the strip itself fulfils the function of protection. The peripheral insulating strip shall be firmly secured to the insulating layer or to the protective layer to avoid the infiltration of the liquid screed. When using synthetic resin screeds or calcium sulphate screeds, the protective layer of the insulating layer must be liquid-tight by for instance being stuck or welded together.
When using gush asphalt screeds, also a therefore suitable protective layer shall be applied, but in this case, liquid tightness is not necessary. Pr
