Abstract

This invention discloses frame profiles for building elements such as windows manufactured by the extrusion or pultrusion of fibre reinforced geopolymer. Extrusion advantageously aligns reinforcement fibres enhancing strength in a single direction. One embodiment of this invention uses cellulosic reinforcement fibre which advantageously chemically bonds to the geopolymer molecules and provides an extremely tough and strong product. The embodied energy in the cellulosic fibre will also be significantly lower than most alternative reinforcement materials.

Claims

1. A frame for a window or door, the frame for receiving glazing, wherein the frame is formed from extruded geopolymer sections.

2. The frame according to claim 1 wherein the geopolymer includes fibres which are aligned so as to reinforce the frame.

3. The frame according to claim 1 wherein the reinforcement is (sub micron) ultra fine fibre reinforcement.

4. The frame according to claim 2 wherein the fibre reinforcement is cellulosic.

5. The frame according to claim 2 wherein the fibre reinforcement is aramid.

6. The frame according to claim 2 wherein the fibre reinforcement is surface treated.

7. The frame according to claim 4 where the reinforcement fibre originates from a root vegetable.

8. The frame according to claim 1 where sections of the frame are joined using a geopolymer adhesive.

9. The frame according to claim 1 wherein the extrusion process produces surface texturing on the frame.

10. The frame according to claim 1 where the sections are produced by extrusion and/or pultrusion.
