Floor heating - Systems and components - Part 4: Installation
This European Standard is applicable to hot water floor heating systems as defined in EN 1264-1:1997.
This European Standard specifies uniform requirements for the design and the construction of heated floor structures to ensure that the underfloor heating system is suited to the particular application.
This European Standard specifies only the particular requirements which are dependent on the floor heating. This European Standard is not applicable to the other elements which are part of all floor structures (heated or not).
Fußboden-Heizung - Systeme und Komponenten - Teil 4: Installation
Diese Europäische Norm gilt für Warmwasser-Fußbodenheizungen, die EN 1264-1:1997 definiert sind. Diese Europäische Norm legt einheitliche Anforderungen an den Aufbau einer beheizten Fußbodenkonstruktion fest, um sicherzustellen, dass die Fußbodenheizung für den jeweiligen Verwendungszweck geeignet ist. Diese Europäische Norm legt nur die besonderen Anforderungen fest, die für die Fußbodenheizung entscheidend sind. Diese Europäische Norm gilt nicht für die weiteren Elemente, die Bestandteil sämtlicher Fußbodenkonstruktionen (beheizt oder unbeheizt) sind.
Chauffage par le sol - Systèmes et composants - Partie 4: Installation
La présente Norme européenne est applicable aux systèmes de chauffage par le sol à eau chaude tels qu'ils sont définis dans l'EN 1264-1:1997.
La présente Norme européenne spécifie les exigences de conception et de mise en ¿uvre des planchers chauffants pour s'assurer que les systèmes de chauffage par le sol sont adaptés à cette application particulière.
La présente Norme européenne traite uniquement des exigences particulières liées au chauffage par le sol. Les autres éléments qui ont rapport avec tous les planchers (chauffés ou non) doivent satisfaire aux autres normes applicables.

In this respect, the necessary structuralheight shall be taken into account.4.2.2Insulating layers, perimeter insulating strip4.2.2.1Insulating layersThe insulating layers shall have the minimum following thermal resistance depending on the thermalconditions under the floor heating structureTable 1 - Minimum thermal resistance of insulating layers (m2K/W) below the floor heating systemexternal air temperature belowheatedroombelowUnheated orintermittent heatedroom below ordirectly on theground *)external designtemperatureTd

5m, the value should be increased.When installing the insulating layer, the insulating panels shall be butted tightly together. Multiple insulatinglayers shall be staggered or placed in such a way that the joints between panels of one layer are out of linewith the next layer.4.2.2.2Perimeter stripPrior to the laying of the screed, a perimeter expansion strip (edge joint) shall be placed along the wallsand other building components penetrating the screed and firmly secured to the supporting base, e.g. doorframes, pillars and risers.The perimeter strip shall rise from the supporting base up to the surface of the finished floor and permit amovement of the screed of at least 5 mm.In the case of multiple insulating layers, the perimeter strip shall be placed prior to application of the upperinsulating layer. When laying the screed, the peripheral insulating strip shall be secured against anychange in position. The top part of the peripheral insulating strip which rise over the finished floor shall notbe cut off until completion of the floor covering and, in the case of textile and plastic coverings, hardeningof the filler.4.2.3Protection layerPrior to laying the screed, the insulation layer shall be covered with a polyethylene film of at least 0,15 mmthickness or with another product equivalent function unless the insulating layer is a comparable protectivecomposit. The individual sections shall overlap at the joints by at least 80 mm.SIST EN 1264-4:2002
EN 1264-4:2001 (E)6In accordance with 4.2.2.2 the protection layer shall be turned up above the upper edge of the perimeterstrip if the strip itself does not fulfill the function of protection.When using liquid screeds, the protection of the insulating layer shall be watertight so that the function ofthe insulating layer is not affected.Protection layers are not humidity barriers.4.2.4Equipment4.2.4.1SafetyA safety device, independent of the control unit, and which operates even in the absence of electric power,shall cut off the heat supply in the floor heating circuit in such a way that the temperature around theheating elements does not exceed the figures given in 4.2.8.1.4.2.4.2Stop
