Energy Rated Windows

We all want our homes to be safe and comfortable. Choosing the right windows and doors is a great place to start. We are all conscious of the need for efficient use of energy in these days of global climate change and potential environmental impact. If the windows in your home consist of single or older double glazed units, replacing them with energy efficient windows will save you money. Energy rated windows can typically reduce heat loss by over 20% compared to more conventional ones with the associated reduction in heating bills, a distinct added attraction in the current economic climate.

Staying safe and secure

Whilst helping to keep you warm, new or replacement windows and doors can also offer you peace of mind of knowing that your property and possessions are suitably protected when you are out or away from home. The better quality CMG modern windows and doors are internally beaded for glazing and use multi-point locking mechanisms to prevent them from being forcibly opened.

For safety’s sake, innovative for escape hinge designs are available and restricted opening hinges can be used to make your windows more safe and secure.

Steps to choosing an energy efficient Insulated glazed Unit

1. The most important thing you can do is select a low emissivity coating – e.g. hard coat or soft coat. In almost all applications, the use of a low e coating will be necessary to meet building control regulations of a 1.8 U-value.

2. Select a good quality warm edge spacer
Super-Spacer is a foam-based spacer bar and therefore 950x less conductive than standard aluminium bars.

3. Argon decreases the heat lost by the IGU through convection. The use of an Argon fill further improves the comfort levels experienced in a room through reduced “chill factor”.

4. Finally, for ultimate WER, select a low iron glass for the outer pane – Low iron glass gives maximum light transmission and perfect clarity.
