Secondary Glazing by Boisse Windows

Create A Peaceful, Warm & Secure Home

Secondary glazing is the process through which a discreet, internal window is fitted to an existing single, double or triple glazed window. Benefits include; increase in acoustic insulation, a substantial reduction in heat loss and increased levels of security.

Secondary glazing is seen as a desirable alternative to double and triple glazing, especially for heritage properties. It allows you to maintain the external character of your property while taking advantage of increased thermal and acoustic insulation.

When you take advantage of secondary double glazing, you enjoy all 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.

Manufactured from durable aluminium and available in over 200 RAL colours, our secondary glazing has a five-year warranty on frames and glazing and a two-year warranty on moving parts. With a comprehensive range of designs, finishes, accessories and glass to choose from, we can provide a perfect solution for any property.

Secondary glazing continues to grow in popularity, in no small part thanks to its unique soundproofing capabilities. The key to minimising noise levels is to install an extra barrier that sound waves find it difficult to pass through. To achieve optimum acoustic performance, we advise that the secondary glazed window is installed with an air cavity of 150mm – 200mm from the primary window. Correctly specified acoustic glass and a high-quality installation will significantly reduce the volume from external sources, eliminating it or reducing it to a whisper.

Warmth is a valuable commodity and creating a second barrier to the elements is an ideal way to reduce wasteful thermal heat loss. In fact, there are few better ways. A large proportion of heat is lost through your existing windows. Installing secondary glazing will add an extra barrier to prevent heat from escaping.

Secondary glazing is supplied with an FSC approved timber subframe. This timber subframe acts as a thermal barrier preventing cold transference, this can reduce levels of existing condensation and increase thermal insulation

Whether it’s for the added security, noise reduction or energy efficiency, our secondary glazing is backed up by an industry-leading five-year warranty on frames and glazing and a two-year warranty on moving parts.
