EN 1264-4:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee CEN/TC 130 "Space heatingappliances without integral heat sources", the secretariat of which is held by UNI.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by February 2002, and conflicting national standards shall bewithdrawn at the latest by February 2002.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,Portugal, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 1264-4:2002



EN 1264-4:2001 (E)4IntroductionThis European Standard for floor heating systems consists of the following parts :-Part 1 : Definitions and Symbols-Part 2 : Determination of
the thermal output-Part 3 : Dimensioning-Part 4 : Installation1ScopeThis 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 floorstructures 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 floorheating. This European Standard is not applicable to the other elements which are part of all floorstructures (heated or not).2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate place in the text, and the publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publications applyto this European Standard only when incorporated in it by amendment or revision. For undated references,the latest edition of the publication referred to applies (including amendments).EN 1057:1996Copper and copper alloys - Seamless, round copper tubes for water and gasin sanitary and heating applications.EN 1254Plumbing fittings.EN 1264-1:1997Floor heating – Systems and components - Part 1: Definitions and Symbols.prEN ISO 15874-1:2001Plastics piping systems for hot and cold water - Polypropylene (PP) – Part 1:General.prEN ISO 15875-1:2001Plastics piping systems for hot and cold water - Crosslinked polyethylene(PEX) - Part 1: General.prEN ISO 15876-1:2001Plastics piping systems for hot and cold water - Polybutylene (PB) - Part 1:General.3Terms, definitions and symbolsFor the purposes of this European Standard, the terms, definitions and symbols given in EN 1264-1:1997apply.4 Requirements4.1General structural preconditionsPreconditions for the construction of a hot water floor heating system are the completion of internalplasterwork and the draught-free closure of all building openings e.g. windows and outer doors.SIST EN 1264-4:2002



EN 1264-4:2001 (E)54.2Building layers, building components4.2.1Supporting baseThe supporting base shall be prepared in accordance with relevant standards.Any pipework or conduits shall be fixed and encased to provide a level base upon which thermal insulationand/or acoustic insulation is added before laying the heating pipes. 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
