Customer had single glazed aluminum windows, he had a lot of windows that really let his property down thermally. Cold nights would be freezing in his home and warm days would warm up and be far too hot to be comfortable.
We recommend White uPVC windows and doors for Allan, double glazing greatly improves thermal efficiency and the uPVC frames are jam packed full of thermal benefits, they also provide the extra comfort of security.
White uPVC windows and doors, we used a combination of different style windows to suit the home and ensure the best outcome for each window. This enabled us to achieve the best ventilation and keep the practical style windows in use.
Key locking handles to all windows to help enhance security.
The standard IGU (insulated glass unit) used, is made up of a 4mm pane with a 16mm argon gas filled gap and 4mm pane on the outside.
Using a standard uPVC double glazed window we can achieve a great u value of 2.3. The u-value is the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating quality ( therefore the lower the u-value the better!) To give you a rough idea of how great that result is a standard single pane window generally sits around the u-value of 6.
The solar heat gain coefficient or SHGC is also nice and low at 0.43. This is the percentage of heat gained from both direct sunlight and absorbed heat. Again smaller the number, the greater the ability to reduce solar heat gain.
