At Mitchell & Dickinson, we’re proud to unveil UV-filtering CosyGlazing – the latest evolution of our award-winning secondary glazing system.

Designed for those who value both elegance and preservation, this innovation uses Perspex® VA Grade UV-filtering panels. The same cutting-edge technology is used to protect priceless artefacts in museums and galleries.

Why choose UV-filtering CosyGlazing?

Sunlight streaming through your windows might feel delightful, but it’s slowly fading your home’s interiors. From antique woodwork and heirloom fabrics to valuable artwork and irreplaceable books, UV rays are silently eroding the beauty and value of your possessions.

Our new UV-filtering CosyGlazing blocks up to 99% of harmful UV light across the 250–385nm wavelength spectrum, offering a discreet and highly effective barrier against damage. The panels are flawlessly clear, preserving natural light and your view while maintaining the exceptional thermal insulation that CosyGlazing is known for. UV-filtering CosyGlazing is also five times stronger than glass and half the weight, making it as practical as it is protective.

A smarter solution than blinds

Unlike blackout blinds that restrict your view or UV films that degrade over time, UV-filtering CosyGlazing provides invisible protection that doesn’t compromise aesthetics. It avoids the patchy light shafts that blinds allow, won’t peel or bubble like film, and delivers a seamless finish that’s virtually invisible from the outside. Designed to work beautifully with period properties and listed buildings, each panel is removable and sits unobtrusively within the window frame.

Who is UV-filtering CosyGlazing for?

UV-filtering CosyGlazing is ideal for homeowners looking to protect fine furnishings, fabrics and artwork without darkening their rooms or obstructing the view. It’s also a perfect fit for heritage buildings, museums and galleries seeking to safeguard delicate exhibits, libraries and archives wanting to preserve vulnerable collections, and retailers who need to shield valuable merchandise in window displays from long-term UV damage.

If you’ve already installed CosyGlazing into your property’s windows, we can replace it with UV-filtering CosyGlazing. There would be an additional charge but you would not need a completely new installation.

Tech you can trust

Crafted using Perspex® VA Grade, this material is exceptionally clear with excellent edge clarity, allowing natural daylight to flow freely while preserving the original colour of interiors and displays. Its UV filtering performance is embedded throughout the sheet, not just on the surface, ensuring consistent protection. Available in a range of thicknesses, it offers flexibility for a range of installations, from domestic settings to institutional heritage environments.
