If you are looking to lower your energy bills and carbon footprint, then upgrading your windows to new double glazing is the perfect place to start. By replacing your old windows with High Performance ‘A’ Rated Windows from Bryant and Cairns, not only will you benefit from real savings on your fuel bills, but you will also be helping reduce the impact on the world’s natural resources.

Did you know that our homes account for a quarter of all CO2 emissions in the UK and that old windows can account for almost 30% of the total heat loss from a home? Not only can ‘A’ rated windows have a zero energy loss over a year cycle, they can actually add energy back into the home via solar gain.

Quality Energy Efficient Double Glazing consists of two panes of coated glass, separated by a layer of trapped Argon gas. This layer of gas has 67% of thermal conductivity of air, which means it’s a poor conductor of heat, thus keeping warm air trapped inside your home and helping improve energy efficiency. The second pane of glass also acts as a secondary barrier to noise, helping keep your home quiet whilst also strengthening the window to give unrivalled security.



Our windows integrate recycled materials by processing old PVCu and introducing it as input material for our KOMMERLING profiles. To ensure only the highest quality of product and surface finish, we combine the recycled pellets with fresh material. The difference we achieve through introducing recycled material alongside the virgin material means a 90% reduction on greenhouse gas emissions. By using our Kommerling window profile, you make an important contribution to conserving valuable resources for future generations as well as being able to enjoy more comfort, security and a long-lasting product thanks to its ingenious design.




Bryant and Cairns Energy Rated Double Glazing will instantly boost your home’s security and value. Our vast range of double glazed window styles are beautifully designed and crafted and due to being highly energy efficient, will over time, save you money on your heating bills and duly go some way to paying for themselves.

Available in a wide range of colours, our super tough PVCu frames employ the latest in replacement technology and are guaranteed to never warp, rot or pit – whatever the Edinburgh weather.

All Bryant and Cairns windows are ‘A’ rated as standard and come backed by our own 10-year product and safety guarantee. It’s not just quality and style that come as standard, but peace of mind too.
