Claims38
An inflatable textile duct suitable for use in an air circulation system to transport a fluid whilst preventing condensation forming thereon, the duct comprising an inner gas-permeable layer and an outer gas-impervious layer formed from a material comprising a textile material, and spacing means located between the inner and outer layers so as to provide one or more inflatable unfilled spaces between the gas-permeable and gas-impervious layers, which unfilled spaces is/are capable of transporting a fluid in use, wherein the inner gas-permeable layer is provided with a porous weave which allows a fluid to pass through the inner gas-permeable layer.
An inflatable textile laminate suitable for forming a textile duct, the textile laminate comprising an inner gas-permeable layer and an outer gas-impervious layer formed from a material comprising a textile material, and spacing means located between the inner and outer layers so as to provide one or more inflatable unfilled spaces between the gas-permeable and the gas-impervious layer, which spaces is/are capable of transporting a fluid in use, the inner gas-permeable layer is provided with a porous weave which allows a fluid to pass through the inner gas-permeable layer, wherein the laminate is formable in to a duct for transporting a fluid, whilst preventing condensation forming thereon.
