DESCRIPTION

Tns invention relates te 3 Otmpted sheet according te the preamhie of claim 1, a composite pane! having seen a dimpled shoot and a method for the therms! insulation of a building according to the preamble of claim 13.

Known dimpled sheets of the aforementioned Nh« sre commonly used for foundation weil protection; »’herein they are located between the ground and the outside of foe foundation wait, or an insolation is so arranged: there in ofoer to also luii s aménage lu mctfors

Dimpled sheets currently used have no ehest on the thermal insolation of buildings. becsüse their thermal transfer resistance is extremely lew due In particular to the low reflectance properties of foe surfaces. Thus the currently ysed dimpled sheets ot brown or Piaci only have a reflectance of 2-5¾.

Known composite panels of the aforementioned type m preferably used in other countess as ilosr panels, wherein they are used between heated living spaces and an unhealed substrate, such as a concrete leer of a basement room or a Bag space built on the ground floor.

The structure of the composite panel: comprises, for example, a hase body mads of a chipboard or a sheet of plywood and a dimpled sheet attached to the base body. The dimpled sheet serves both es ä vapour barrier to moisture, which might possibly rise from the concrete: floor, as well as for the elastic mounting of the floorboards, in order to achieve a certain damping effect.

However, foe use such permis has the drawback ihat. despite firs cavities between the dimpled sheer and the concrete hase as: well as in foe dimples themselves, they only offer an wsuiclont insolation, Known solutions to fois problem provide for the use of an additional insulating layer between foe dsmpied sheet and foe base body. This may improve foe overall thermal insulation although, due to the thickness repaired of the insulation layer, ceiling height w tost, which is problematic especially in the use of such a composite panel in old buildings. Furthermore, foe production ot such composite panels designed with a layer of insulating material is very yme-consumteg arte, cot isas! of all. extremely expensive duo to the necessary additional insulation material. US 5,SS,4f discloses a panel material which comprises a plurality of truncated conical projections having a beste square shape, and: foat is used: in conjunction with, an upper and tower plate as a core element of a composite component. The projections have a psrtfeuiar basic hexagonal: shape- and are internally hollow. The panel material semes as a composite pane! in conjunction with foe fop and bottom plate for use in foe interior of buildings. GS 2 0?S 41 § A discloses an insulating material for foe surfaces of usings or, for example:, hours, The insulating material Is formed by two flexible Plastic cheats which have bulges in foe form of bags fost esn be-provided with s heat-rsfiecfom alumínium coating on foe inside and/er outside. After joining the two films fa tea insulating materiéi by welding, a composite arrangement is created with folly enclosed bags, which should bring: about thermal insulation. The features of foe preamble of claim 1 are known irr fois context. IP 2053-332782 A discloses a foie sheet materia) which absofos magnetic waves and is termed through two-layer structures. Coe foyer structure is In foe form of a metallic reflecting layer while the other layer structure is in the form of an eieforomagaelto wave -absorbing layer. US 2003/0-148033 A1 discloses a composite material which consists of three layers arte may be used tor decorative purposes e,g, in 'building wails, as well as for thermal tesateiiors, A middle layer is made of transparent plante material with pigments and s Itanium dioxin: layer and covered by so upper and lower layer el transparent plastic materia!. WO 82/03883 A Assisses a promptive giato for&mmâ building walio pf teSi. Th« protectee jyiate. fe made of a piasfe mats# and lias a ptofüy of dimpfedite: protrusions, which are formed by craieMike consavite. The, protective pista is preferably used as a protective piste hetesen a bottom layer of chipboard and a cast laver, fer exempte, lo form a dreisage, ÜE 21 40 851 At discloses a planar insulation, parficutedy for buildings, tents or the Ute,, comprising si least three infersennected layers. The middle layer includes a plurality of spacer members, which may he dimplo-llte in form and, in each case, toms Closed cavities. The cavities are fled with gas to fully prevent beat conduction between the two eater layers.;

The invention thereto has the objest ef providing a dimpled sheet constructed as simply as possible with a high thermal resistance as weü as improving the thermal insolation of a composite panel of the aforementioned type while maintaining the basic structure of known composite panels. Moreover, the invention has tor its object a method lor the thermal insolation of a building, irr particular for thermally insulating a floor.

The invention solves the problem: through a dimpled sheer according to the features of claim 1, a composite panel according to claim 8, and a method according to ólaim 1 $. Advantageous developments of the invention are described in the dependent claims. A characteristic of the dimpled sheet according to the Inventes is a surface heving a high, reflectance. In the context of the invention:, a high müectsnca is understood to mean a surface rettenten of mors titan .20%. Basically, the dimpled sheet may have hollow dimples formed on one nr doth: sides of a pisne, wherein the dimpled: sheets preferably have dimples on one side for fog produeten of the composite panel according fo the invention:, in this case, the dimpled sheet is food with Its dimpled side facing away from a base body ,

According to the invention, the dimpled sheet is made et pigmented plastic fo reflect infrared radiation. Such a plastic dimpled sheet ts particularly distinguished by its simple and oost-effoctive production as well as Its malleability and flexibility. These properties also allow a particulerly cosimfieclive and irouhie-fres production of a composite panel.

The total thermae resistance of the: dimpled sheet and the composite panei comprises the heat transfer resistance fo radiant heat and: the hsat transfer resistance fo convective: heel. Mathematically calculated, foe tots! beat transfer resistance is foe reciprocal of foe sum of the thermal resistances to convective end: radient best. The host'transfer resistance to radiant heat and thee the total thermal resistance may be Influenced through the high reflectivity of the surface of the dimpled sheet.

The wide application rasp of the: dimpled sheet according to foe invention, e.g, for fhe construction of a floor, the sealing of building: wails at or shove tbc ground:, or lor tosten in foe roof, enables the building to be provided with a particularly nigh and eompiete thermal insulation, leading to 3 sfoniteant reduction In heating costs.

Thus, as the high refientivlty of fne surface of the dimpleu sheet significantly improves the heat transfer resistance to radiant treat, it Is necessary fost the for foyers are limited to the surtece of me dimpled sheet. The use ol the tempted sheet according to the Invention tor foe construction of the composite panei secerning to the invention ensures foe existence of sufficient air layers at the surface of the dimpled sheet corresponding: fo foe testdbntfon of ths dimplos and open spaces.

The preferred use of 0 dimpled sheet with dimples formed: on one side in a pesten of use of foe composite panel, for exemple, when used as a floor prate. limits the air foyers fo forge areas of the dimpled sheet. Thus, there Is on air layer in the hollow chambers of the dimples formed between foe dimpled sheet and ths main body. A further labyrinthine contiguous air layer exists between foe dimples. These extensive amas ensure foot foe total thermal resistance of the composite sheet is subsfontteiiy increased by the high reflected)1 of me dira pled sheet.

According to the invention, the suite· te foe dimpled sheet has a reflectance or more than 02 {20% mfioctancei, to particular mo:« than 8.3$ (35% reflection}, or 0.5 (§0% refection;:. Even at a rebectones of 8.2, the heat transfer resistance of the, dimpled sheet compared with dark dimpled sheets at a reflectance of 8.82 to 0,05,. is higher by a factor of at least 1.2. in the esse of a: reflectance of 0,35 or 8.δ, fee thermal: feansfer resistance of the composite panel corresponds to approximately 1.4 and 1,7 tes the value for dark dimpled sheets. Thus it may be ensured that high thermal insulation is achieved without the use of additional insulation materials while the insulation perfermance Is Increased.

According; to soother embodiment of the invention, the dimpled sheet has s smooth surfaco. Such a configuration of the surface structure of fee dimpled: sheet causes the reflectance of the dimpled sheet to: he increased in a complementary manner, thereby achieving an additional increase in the heat transfer resistance to radiant heat, so that the total thermal resistance of the composite pane! is further improved.

There are manifold ipessihliiss tor fonning the dimpled sheet wir a high reflectivity. According to one development ef the ioventfori, toe surface of the dimpled sheet has a rofetive coating, The. eoatlng of the dimpled street may be applied in a mechanical manner to toe surface of the dimpled sheet by vapour depositien or otherwise, depending: on the type of costing.

The coating may further be sc formed that Ibis adapted to retet electromagnetic radiation, or at least attenuate it. The attenuation amounts to at least S ®, preferably a! least 1ö dB, pateiady preferably si least 15 dB This design of the dimpled sheet: according to the invention enhances its appifoatfoo range in a complementary manner, wherein increasing importance is given to the shielding of living and warning spaces against unwanted electromagnetic radiate;.·

The coating may be produced, for example, by applying a pigment-containing liquid to the surface of the dimpled sheet, whereto toe pigments remain on the surface of the dimpled sheet ate the passage of toe figuid and: give the dimpled sheet its reflective properties.

According to the invention the plastic contains colour pigments, in particular titanium dioxide or metal pigments, tor example, aluminium pigments. The pigments may he mixed prior to the extrusion of the dimpled sheet in a corresponding plastic wait, so that post-extrusion treatment ol the dimpled sheet to increase its reflectance may he dispensed with. The titanium dioxide, hut especially toe metal pigments, tor example, the aiumimum pigments are characterised by their property that, even at tow concentrations in the plastic malt, they facilitate the production of a dimpled sheet having a high reflectance, The positive properties of: the plastie dimpled: sheet, such as flexibility, impact resistance, strength, etc., are not adversely affected: by toe tetem dioxide.

The dimpled sheet according to the invention may be used, in principle, atone, tor example tor thermal: tosutotion fn flooring, roofing: or wailing Moreover, the dimpled sheet may also be combined with other materials nr building materials, such as seats or insulations, wherein the production of a corresponding prefabricated product Is possible, which then has the advantages of the dimpled sheet according to the invention and of the further produces).

When using the dimpled sheet for the production of the composite panel, the base body may be freely selected corresponding to the field of appifcaSen of toe composite panel. According: to an advantageous development of the invention, the case body is formed fmm chipboard cr plywood.

Chipboard and plywood panels are distinguished, inter alia, through fbair low-cosl production, their simple processing and by their particularly good insulation properties, so that the features of the composite panel according to the invention may be further improved, tosreever, this embodiment of the invention allows particularly cost-effective manufacturing of the composite panel according to toe invention, to addition to the use of particle board or plywood as the base body, mown thermal insulation may also be used, such as mineral fibre boards:, in order to produce a composite pane!. This may also be used in the roof area or for the insulation of the building walls. According to armiher embodiment of tbs composite sheet, a metal foil or metallised plastic film is arranged on the dimpled sheaf elds facing the base body or between: fee dimpled sheet and ffss base body. This particularly simple embodiment further improves the heat Pansier resistance of the composite body in a complementary manner.

According te s development οί -tee composite panel, tes base beds? comprises tm pate of parallel edges, wherein adjacent edges are' provided with coupling elements- in foe form of a groove en one and a spring that life into tee groove on the other. This development has the advantage that tee layfeg ef the -composite panel Is facilitated end the composite paseis rosy he connected to each other in a ether fefra-Äg »rasnner, which enhances the stability of the joining of several composite panels. A characteristic festere of tee invonfivs method for tee thermai insulation of a building:, in: pahiooiar for thermally insulating a tot is that first a dimpled sheer with a reflectance of more than Cs2 {20% reflection), especially more than 0 35 (35% rejection), or δ,5 ίβ% resection). Is placed on the surface to he insulated, in particular on the fee and then a case body is applied to tee dimpled sheet. This method offers a garf-oefady simple way of building a thermal insulation on the spot, for-exempte, directly on the site. The laying of tee dimpled sheet here is particularly simple on account of its flexibility and ease of processing:.

When using a plastic dlmpted sheet, the dimpled sheet that is normally available fe the form: of plastic roils, only needs to he rolled onto the surface to fee- Insulated In order to produce tee thermal insulation. Than -tee- base body Is attached: to tee dimpled sheet.
