Future Glaze Windows


Secondary glazing is the process through which a discreet, internal window is fitted to an existing single or double glazed window to enhance performance. It’s seen as a desirable alternative to double glazing – especially for heritage properties – as it allows you to maintain the external character of the structure whilst taking advantage of the benefits created by double glazing. When you take advantage of secondary double glazing, you enjoy all of the benefits that come with an extra layer of insulation over your windows. This cuts down on heat transfer, which means that your home stays warmer in the winter and cooler in the summer. But it also insulates against sound and enhances the security of your property.

Secondary glazing actually exceeds the value of traditional double glazing. In addition to providing outstanding thermal and noise insulation, this style of glazing is also extremely discrete – to the extent that a casual observer would be unlikely to notice its presence at all. This level of subtlety allows historic homes to retain their character whilst taking advantage of more recent breakthroughs in glazing. We offer a wide variety of styles and finishes that you can install at your property, ensuring that the finish you choose blends perfectly with the existing design style and motif that are already in place.
