Abstract
The substrate plate 1 is used in under floor heating systems and comprises a thermally insulating layer 2 made of an expanded polymer such as expanded polystyrene, a heat diffusing layer 2 made of a metal foil such as alumina foil and a protective layer 4 made of a polymeric material such as polyethylene. The heat diffusing layer is adhered to the thermally insulating layer. In use, the substrate plate is arranged alongside similar plates on a support surface 13 and heating pipes 5 of an under floor heating system are laid on the protective layer and fixed thereto by anchoring fasteners 7. Mortar 6, preferably a cementitious or anhydrite mixture, is poured on the plates, embedding the pipes and fixtures. The plate preferably includes guide indicia (12, figure 2) that mark where the pipes should be laid and an overlap portion 11 that extends over an adjacent plate in use to prevent wet mortar penetrating between adjacent plates during pouring. Ideally the fixtures include flanges (10, figure 3) to prevent wet mortar from penetrating past the protective layer. The protective layer can be sprayed onto the heat diffusing layer or provided as a sheet to be adhered.
Description
AN UNDERFLOOR HEATING SYSTEM AND.A PRECAST SUBSTRATE_PLATE FOR
SUCH UNDERELOOR HEATING SYSTEM
ThPbnicallIc1 The present inventions relates to an underficor heating system comprising protective layer to protect a heat-diffL sing layer made of a metal foil, having thermal againt some chemical cprnponents usuaFly sed in a rid heat-transrnittin stratum made of a mortar poured thereor. The present invention also reates to a precast substrate plate comprising a protective layer apphcable to said underfloor heating system.
Bçroundoftliejnvention Underfioor heating systems are, known comprising substrate plates laid side by a de on a wpport surface heating pipes arranged on the substrate piates according to a pattern, said heating pipes making part of a heating circuit along which a heat transfer fluid is circulated, fasteners anchohrt the heating pipes to. .the substrate plates. and a rigid heat-transmitting stratum made of a mortar laid on the substrate plates embedding the heating pipes and the fasteners, wherein eadh. of the substrate plates includes a heat-insulating layer made of an expanded polymer, such as expanded polystyrene, and a heat-diffusing layer made of a metal foil, for example alumina foil, adhered to a flat upper surface of said heat-insulating layer.
A substrate plate of this kind is commercialized under the frademark "DIFUTEC!' by the applicant.
A drawback with this kind of underflour heating systems is that the metal foil constituting the heat-diffusing layer whith i in contact with the mortar constituting the rigid heat-transmitting stiatum has no protection against some ot the cneriical components usuall9 used in t.he mprtr formulations.
Another drawback is th& the fasteners anchohng the heating pipes usual!y have harpoc n-shaped legs which are driven into the substrate plate making holes therein, and the mortar constituting the rigid neat-transmitting stratum, which is pourea thereon in a wet state, penetrates into the substrate. plate through said holes causing undesired thermal bridges through the heat-insulating layer.
Still another drawback is that the mortar constituting the rigid heat4ransmitting stratum can leak into a gap between adjacent substrate plates when the mortar is poured thereon in a wet state..

Thus, the urldeiftoor heavg system Is asse mbleci 41 place layer is located below the heating pipes and. between the heat-diffusing layer of tht substrate plates and the tid hat4ranmitting stratum so that the protective layer protects the metal foil cohstitutlng the heat-diffusing layer against some óhethical components present in themortaroonstituting the dgid tStrann*'ihg stratum.
Preferably, the heat-diffusing layer and the prc4ettnee layer of each substrate plate' have an overlap portion extending Outwards beyond.a Side edge oft the heat-Insulating 3 layer. When ir,flalRng the underfioor hetlng syn, said overlap port1o of each substrate plate. Is arranged overlapping a' poition of thø heat-diffusing layet'and ptat&h,e layer of a neighbouring substrate plate, thus preyentng the cementitious mixture cf the rigid heat-transmitting stratum, which is poure.d in a wet state, from infiltrating in * gap between two adjacent substrate plates. in one embodiment, the overlap portions include a aeifadhesive coating on its underside.
Optionay, the subsirate plate compnsee guiding indicia which are visible on a upper surface thereof, said guiding indicia serving as a visual guide for the Fnstallation of the heating pipas on the substrate plates.
Each of the aforementioned fasteners has a retaining portion to embrace the heating pipe, and at east one, preferably two harpoon-shaped legs which in use are driven into the substrate plate. Each harpoon-shaped leg has a flange arranged the.rearound, said flange being confiwured and arranged so as to contact an upper surface of the substrate plate covering a hole made therein by the respective harpoon-shaped leg when the fastener is assembled in an operative position. Thus, the flahges of the fasteners prevent the mortar constituting the rigia heat-transmitting stratum which is poured thereon n a wet state, from penetrating into the substrate plate through the rides formed therein by the harpoon-shaped legs of: the fateflers, and avoid formation of thermal bridges through the substrate plate caused by the mortar.
According to a second aspect, the present invention provides a precast substrate plate for an underfloor heating system;5aid precast substrate., plate comprising a heat- 20.insulatin layer made of an expanded polymer and a heat-diffusing layer made of a metal foil adhered to a flat upper surface of sai.d heat-insulating layer. A plurality of said precast substrate plates are intended for being laid side by side on a support surface, with heathig pipes making part of a heating circuit along which a heat transfer fluid is circulated arranged on the precast substrate piates and anchored thereto by fasteners, and with a rigid. heat-trahsniitting stratum made of a mortar laid on the precast substrate plates embedding the heating pipes ano said fasteners The precast substrate plate of the present invention further comprises a protective layer made of.a polymeric material lai'd'on an upper surface of'said heatdiffusing layer.
The protective layer is laid on said upper surface of the heat4iffusing layer by spraying said polymeric material in a liquid state and subsequent drying in a precast operation or by adhering a sheet of said polymeric, material thereto in a precast operation.
In one embodiment, the polymeric material constituting the protective layer is polyethylene. The' protective layer has a thickness. ranging from 0.025 to 0.050 mm.
In one embodi.meht, the heat-insulating layer is made of expanded polystyrene.
The heat-insulating layer has a thickness ranging from 10 to 70 mm.
ri one ernbodrnant the heat diffusng layer s made of alumna to I The beat-diffusing layer hs a thickness ranging from 015 to Q35 mm.
Preferably, the heatdiffusing layer and the protective layer has an overlap portion extending *outwaPds beyond at [east one side edge, and preferably beyond two adjacent side edges of tne heat-insulating layer, and said ovet lap porion ncludes a seif-adhesive coating on its underside.
The substrate plate is preferably rectangular in shape, and optionally includes guiding indicia printed on the heat-diffusing layer or on the protective layer so that said gLuding indicia are visible on an upper surface of the substrate plate.
The heat-insulating layer made of expanded polymer thermally insulates the heating pipes from the support surface by virtue of the high thermal insulation properties of the erpanded polymer, especffiuly expanded polystyrene. The heat-diffusing layer made.oi metal fdil diffuses heat from the heatin pipes throuhout the rigid heat-transmitting stratum b virtue of the high thermal conductive proprties of the mtl foil, epecially alumina foil, and alloWs the heat transfer fluid to work at lower temperatures.
The protective layer protects the metal foil constituting the heat-diffusing layer against see chemIcal components usually present in the mortar constituting the rigid heat-transmitting stratum by virtue of the high chemical protective capacities of the polymer, especially polyethylene.
The substrate plate of the present invention has a flat and smooth upper surface allowing to lay and fasten thereon heating pipes of any desired diameter according to any desmed pattern, and allows the mortar cobstituting the rigid heat4ransmltting stratum to fully embed the heating pipes and the fasteners.
