Our promise of suitability


Listed buildings and projects where conservation of the appearance of original windows is required can benefit from the greatly improved thermal efficiency and noise reduction offered by modern secondary glazing techniques. Here, using the well known Granada system, the expertise, and experience of Climax can be harnessed to achieve optimum levels of energy conservation and heat retention by installing unobtrusive secondary glazing which also provides easy access to the original window for cleaning or maintenance. In most instances, Climax secondary glazing designs can be made invisible from the outside of the property.

A wide range of high quality lift-out, horizontal and vertical sliding, arched or curved head secondary glazing units can be individually tailored to fit virtually any building whatever its age or architectural style.
