Abstract
A method of manufacturing an insulated frame member including first and second frame components held in a spaced relationship by a first, glazing unit facing connector component and by a second connector component, the first and second frame components together defining a void substantially filled with a foamed material, wherein the first connector component is of width greater than or equal to the thickness of the glazing unit.
Claims12
A method of manufacturing an insulated frame member for supporting a glazing unit, the insulated frame member comprising first and second frame components held in a spaced relationship by a first connector component and by a second connector component, the first connector component facing towards the glazing unit, in use, the first and second frame components together defining a void substantially filled with a foamed material, the method comprising the steps of:
- (a) assembling the first and second frame components and the first and second connector components by sliding the frame and connector components relative to one another in a longitudinal direction of the frame member to define the void;
- and
- (b) introducing a foamable material into the void and foaming the foamable material in situ to exert a pressure upon the first and second frame components and upon the first and second connector components, wherein the first connector component is of a width greater than or equal to the thickness of the glazing unit.
A method of manufacturing a frame member comprising first and second frame components held in a spaced relationship by a first, glazing unit facing connector component and by a second connector component, the first and second frame components together defining a void substantially filled with a foamed material, wherein the first connector component is of width greater than or equal to the thickness of the glazing unit, the method comprising the steps of assembling the first and second frame components and first and second connector components to define an elongate void, and injecting a liquid foaming material into the void.
