<p>A layered latticed window frame 11, the layered latticed frame having a plurality of window element apertures and a first 11a and second 11b latticed frame layer and a thermally insulating material 17 between the first and second latticed frame layers. Preferably the insulating material is a thermally insulating tape with a thickness of less than 4mm, preferably 2-4mm, or it may be a non-porous material e.g. a closed cell foam. The insulating material may join or adhere the first and second lattice layers together. The window glazing elements 15 are located in lattice apertures 13a/b and may be held in place by a putty, adhesive or other suitable system. A method of forming a lattice window frame by providing the first and second latticed layer and a thermally insulating material therebetween is also claimed. The system may be used in the renovation of an old house having single glazed lead frames to provide double glazing (or triple glazing etc.).</p> |
