Granada’s Secondary Glazing will make your home Peaceful, Warm and Secure. Secondary Glazing is a discreet internal window that is installed in conjunction with your primary window. It is often found within period properties and homes that want to increase both acoustic and thermal performance substantially.

We offer a wide range of secondary glazing styles to complement all homes and window types. Granada’s secondary glazing can give you full access to your primary window for cleaning, general maintenance and ventilation where the slimline profile is both durable and unobtrusive.

When you take advantage of secondary glazing, you enjoy all the benefits that come with an extra layer of insulation. 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.

Granada Glazing is the UK’s largest manufacturer and supplier of bespoke aluminium secondary glazing. We have partnered with trusted trade installers and local window companies to supply and install our range of secondary glazing products. Our dealer network covers the whole of the United Kingdom and Ireland and is trained to offer the very best acoustic and thermal solutions.
