A building component in the form of an inflatable cushion, comprising at least two sheets of plastics foil and a relatively rigid frame surrounding and supporting the foil sheets, and liquid retaining means associated with one of the sheets wherein the liquid retaining means comprises means applied to an outermost, exterior sheet of the cushion and arranged to retain rain water on the outermost, exterior sheet.
A building component in the form of an inflatable cushion, comprising at least two sheets of plastics foil and a relatively rigid frame surrounding and supporting the foil sheets, and liquid retaining means associated with one of the sheets, wherein the liquid retaining means comprises a further sheet of plastics material overlying a sheet of the cushion, thereby defining a fluid-tight compartment between the further sheet and the said sheet, the compartment being fillable with a liquid;
- and wherein the further sheet is partially fixed to the said outermost sheet along lines, thereby defining the compartment as a continuous channel.
A building component in the form of an inflatable cushion, comprising at least two sheets of plastics foil and a relatively rigid frame surrounding and supporting the foil sheets, and liquid retaining means associated with one of the sheets, wherein the liquid retaining means comprises a further sheet of plastics material overlying a sheet of the cushion, thereby defining a fluid-tight compartment between the further sheet and the said sheet, the compartment being fillable with a liquid;
- the said sheet and the further sheet being fixed together at individual points.
