Abstract
Abstract Covering material for walls, facades, roofs or the like, which is flown through by a heat transfer medium for the assimilation or absorption of radiant heat and/or heat from the environment and by which the shape and/or size of the cross-section of the flow channels for the heat transfer medium is variable by change of the pressure in the flow channels, for example, by change of the pressure in the heat transfer medium for knocking off the ice and/or snow edges as well as for the change of the free cross-section for the heat transfer medium. Further, a distributor or collector channel molding is provided with which the covering material can be connected into the circuit for the heat transfer medium.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
A covering for walls, facades and roofs comprising webs which for the absorption of radiant and environmental heat having flow channels running parallel to each other for a heat transfer medium which flows through the channels and are made of flexible synthetic material, the improvement wherein additional channels (33, 42) are formed in the webs running approximately parallel to said flow channels (e.g. 31, 37), a flow through medium being contained in the additional channels, the external shape of the webs and the size of the cross section of the additional channels are variable by means of change of the pressure of the medium in said additional channels, an expandable base foil defining an outer peripheral wall of each of said additional channels, respectively, a plurality of said flow channels being attached to each of said base foil of said additional channels, respectively, and a support foil being connected to ends of said base foils, respectively, said support foil forms a bottom peripheral wall of all of said additional channels.
Claim 2
Dependent Claim
170 words
A covering for walls, facades and roofs comprising webs which for the absorption of radiant and environmental heat having flow channels running parallel to each other for a heat transfer medium which flows through the channels and are made of flexible synthetic material, the improvement wherein additional channels (33, 42) are formed in the webs running approximately parallel to said flow channels (e.g. 31, 37), a flow through medium being contained in the additional channels, the external shape of the webs and the size of the cross section of the additional channels are variable by means of change of the pressure of the medium in said additional channels, an expandable base foil defining an outer peripheral wall of each of said additional channels, respectively, a plurality of said flow channels being attached to each of said base foil of said additional channels, respectively, and a support foil being connected to ends of said base foils, respectively, said support foil forms a bottom peripheral wall of all of said additional channels.
Claim 3
Dependent Claim
149 words
A covering for walls, facades and roofs comprising webs which for the absorption of radiant and environmental heat having flow channels running parallel to each other for a heat transfer medium which flows through the channels and are made of flexible synthetic material, the improvement wherein the webs are made by cutting to length endless webs so as to define flow channels with open ends, and that said flow channels by change of the pressure of the heat transfer medium in the flow channels, are variable in the external form of said webs and the size of the cross section of said flow channels are variable for removing ice, a support, and foil strips forming a drop-shaped outer peripheral wall of said flow channels, respectively, and each of said foil strips having longitudinal edges connected to said support partially overlapping said edges of an adjacent of said foil strips.
Claim 4
Dependent Claim
149 words
A covering for walls, facades and roofs comprising webs which for the absorption of radiant and environmental heat having flow channels running parallel to each other for a heat transfer medium which flows through the channels and are made of flexible synthetic material, the improvement wherein the webs are made by cutting to length endless webs so as to define flow channels with open ends, and that said flow channels by change of the pressure of the heat transfer medium in the flow channels, are variable in the external form of said webs and the size of the cross section of said flow channels are variable for removing ice, a support, and foil strips forming a drop-shaped outer peripheral wall of said flow channels, respectively, and each of said foil strips having longitudinal edges connected to said support partially overlapping said edges of an adjacent of said foil strips.
Claim 5
Dependent Claim
55 words
The covering according to claim 2, further comprising a flexible and elastic partition disposed in each of said flow channels divides each of said flow channels into one additional channel thereinside, respectively, each said additional channels being changeable in cross-section inside said flow channels by a pressure change of a heat transfer medium flowing therethrough.
Claim 6
Dependent Claim
148 words
A covering for walls, facades and roofs comprising webs which for the absorption of radiant and environmental heat having flow channels running parallel to each other for a heat transfer medium which flows through the channels and are made of flexible synthetic material, the improvement wherein additional channels (33, 42) are formed in the webs running approximately parallel to said flow channels (e.g. 33, 37), a flow through medium being contained in the additional channels, the external shape of the webs and the size of the cross section of the additional channels are variable by means of change of the pressure of the medium in said additional channels, a support, and foil strips forming a drop-shaped outer peripheral wall of said flow channels, respectively, and each of said foil strips having longitudinal edges connected to said support partially overlapping said edges of an adjacent of said foil strips.
