MARLEY Mouldings, the US subsidiary of UK-based Marley Building Materials, has developed a cellular PVC profile window frame system which it believes is a world first.
Launched recently in the US, it is expected to arrive in the UK by this summer.
The product comprises two types of plastic extrusion combined in one profile.
The outside surface is treated with a weatherproof finish which does not yellow with age as some PVC-u frames do. The inside of the frame has a finish called clearwood which can be stained to look like natural wood, or painted.
According to Marley, this results in a maintenance-free product with the appearance of wood, but with none of the complications likely to arise when fitting timber on to a PVC-u frame.
The material is a good thermal insulator two and a half times better than softwood, says Marley and it can be heated and bent to form arches or round windows.
And according to Art Ramey, executive vice president of sales at Marley Mouldings in Virginia, it will be arriving here in spring or summer this year.
