What is Double Glazing?

Double glazing is hands down one of the best choices you can make when it comes to improving the performance and energy efficiency of your Cardiff home. It can help your home to better retain heat, preventing heat loss. But it can also control heat movement in both directions, ensuring that your home doesn’t overheat in the height of summer either!
This is achieved through the way double glazing is made – it’s two panes of glass separated by a thin layer of inert argon gas. Argon gas is an exceptionally poor heat conductor, which makes it really difficult for heat to pass through it. This means the heat has to stay trapped inside where it belongs!
Without a doubt, there’s no better upgrade to choose for your Cardiff home than our super energy efficient double glazing!


Conservatories, Windows and Doors Cardiff

We manufacture and install a wide range of double glazed home improvement products, to help you find the perfect solution to suit your Cardiff home’s needs. From conservatories and guttering, to windows and doors, there’s something to suit every property!

Some of the double glazed windows we offer include replacement windows, casement windows, sliding sash windows, flush sash windows, bow and bay windows, and tilt and turn windows. All of these are made to measure and fully bespoke, and of course feature double glazing as standard!

When it comes to doors, we’ve got you covered from front to back (and patio!). From composite doors and uPVC doors for the front of your home, to patio doors, French doors, bifold doors and more for the back garden, you’ll be transitioning in style throughout your home!
