Stormrange Range

Lipped Casement Windows are the most widely used window design in England. They include a casement that slightly overlaps the face of the frame when closed, this design may offer additional protection against the elements in areas of extreme exposure, hence being widely known as ‘stormproof’ windows.
Combined with double-glazing and engineered timber, you can be sure of energy efficiency and low maintenance. The double glazed timber windows are available in both Conventional & Contemporary styles, their sophistication is unobtrusive but entirely reassuring.
As with all our products you can match your paint finish or wood stain to any of the Farrow & Ball or Fired Earth colours or choose from one or two of the many RAL colours – enabling easy coordination with your home and style.
