Double Glazed Windows & Doors in the UK

Double Glazing UK: Double glazing can reduce noise levels, enhance your home's energy efficiency and improve security. The expression double glazing actually relates to the method of making these windows using two panes of glass, with a gas filled layer trapped between them (typically argon). Acting like an insulating material, this gas provides excellent sound proofing and thermal qualities for any home or property.

If you have already got older double glazing in your property in the UK but are dealing with problems, such as condensation between the panes or draughts, it might be time to consider upgrading your windows.

Condensation occurs in the gap between the window panes when gaps appear in the sealed unit and warm air enters from inside the property. As the cooler exterior glass pane comes into contact with the heated air, moisture is formed as condensation. If this happens on a regular basis it's time to upgrade your current windows.

An immediate improvement in the warmth and soundproofing will be noticed if your home in the UK currently has windows with single glazing and you switch to double glazing. Upgrading to double glazing could also add extra value to your property, which of course will be an advantage if you eventually decide to sell up.


By hiring a specialist double glazing installer in the UK, you should be able to obtain windows that match your choice of style and accentuate your house perfectly. From period sash windows for older houses, to modern casement windows and patio doors, double glazed frames are available in a large selection of materials, sizes and colours.

Hinged on one side, double glazed casement windows can be made to open outwards or inwards depending on the design. This means they are easier to clean, and can provide ample airflow during the summertime. Casement windows can also come in a tilt and turn window for additional security. Permitting them to be opened slightly, tilt and turn double glazed windows have an extra hinge. As they can be locked into position when only partly open to allow for a cool breeze to enter the room, the security is increased.

Double glazing sash windows with a traditional look can be purchased to complement older or period homes in the UK. These can be single hung, where only one sash is moveable, or double hung, where both of the sashes can be slid open. The sash windows of the past had a reputation for poor energy efficiency, however this issue has for the most part been lessened with modern double glazing designs, and with regard to thermal losses, there is very little between sash and casement windows nowadays.

Bay windows look fantastic and can bring a feeling of space to a room. If your home in the UK already has a bay window, you could replace it with a double glazed equivalent. Bay windows bring lots of character and style to a home, however the main advantage is the quantity of light that they allow to flood into a room. An additional plus point is having the opportunity to install a window seat, if the sill is deep enough on the inside of the window.

With the development of modern uPVC materials, virtually any colour you desire is possible in today's double glazed window frames. For a traditional look you could also have timber frames, or for a more modern feel even choose aluminium double glazing. Aluminium windows no longer have to be a dull, grey and rather bland looking frame for your windows, and can easily be coloured to match your house.

All new double glazed windows must display the CE approval mark. This proves the standard of the frame and of the glass and the mark should be plainly visible on the inside of the sealed glass unit and on the frame. For all windows and doors made in Britain and the EU, the CE logo is a necessity. If CE approved materials aren't used by your UK double glazing firm, they may be using cheaper components and making their windows using less rigorous specifications. It is best to always insist that the company only uses double glazing that comes with CE approval and is backed up with a warranty.


Finding an established double glazing specialist in the UK for your new windows can always start with a recommendation from friends or neighbours.

According to the number of doors and windows you need, your frame type, the design of window and the opening options, this may take anywhere from several days to a few weeks.
