Secondary Glazing Experts

Granada Glazing has been in business for over 45 years, and we are proud to be the largest manufacturer of secondary glazing products in the UK. Since 1980, we've made over a million frames, averaging roughly 100 frames a day, and around 25,000 every year. This level of experience is what makes us experts in our industry, and why so many architects choose to specify Granada Glazing products.

Our Mission

To provide premium glazing solutions that enhance comfort, efficiency, and security.

Sustainability

Sustainability is at the heart of Granada's approach to secondary glazing. By improving the performance and extending the lifespan of existing windows, particularly in heritage and Grade-listed buildings, our secondary glazing solutions reduce energy consumption and carbon emissions, while significantly improving thermal efficiency and acoustic performance for long-term environmental sustainability.

Growth

Our growth reflects Granada's commitment to delivering exceptional secondary glazing solutions. With increased expertise and capacity, we can support more heritage and listed-building projects, providing enhanced thermal insulation, noise reduction, and sustainable performance, helping clients protect both their properties and the environment for years to come.
