What are the most energy-efficient windows?
While there are a variety of styles and materials available, when judging how energy-efficient windows are, we need to look at their performance. For this, we need to consider:
- Double or triple glazing: these windows consist of two or three layers of glass separated by a layer of inert gas. This design reduces heat transfer and enhances insulation.
- Coatings: the coating is key to energy-efficient glass. It’s worth noting that different levels of coated glass perform differently.
- Thermal efficiency: this is tested by placing windows in a controlled environment where the amount of heat and light that can go through the window are measured, as well as how much air can leak in or out.
- Energy-efficient ratings: these ratings show a window’s performance in terms of heat retention and solar heat gain. Here at Lee Glass, we sell A-rated windows, making them highly energy-efficient and helping to cut your energy costs. It is not always feasible to achieve A-rating for all products, such as composite and residential doors due to the metal in them, however they are still energy-efficient and comply with building regulations.
- Insulated frames: the frames of energy-efficient windows are often made from materials like uPVC or composite materials that provide excellent insulation and durability.
- Warm edge spacers: these insulating spacers between the window panes reduce condensation and heat transfer at the edges of the glass.
It’s worth noting that even the most energy-efficient windows won’t perform at their best if they are not installed correctly. Make sure you choose an accredited, reputable installer who will seal and insulate the windows properly.
Why is repairing a window so important?
Damaged or poorly sealed windows can be a major source of energy wastage. Broken seals and cracked glass allow cold draughts into your home during the winter and cool air to escape during the summer. By addressing these issues promptly, you can prevent unnecessary energy loss and reduce your heating and cooling bills.
Do energy-efficient windows make a difference?
Absolutely! Energy-efficient windows are a highly effective way of reducing energy consumption, particularly at a time when government building regulations are steering heavily towards a net zero future. Not only do they make a difference to the environment, but you will see considerable savings on your energy bills too that can offset the initial investment in these windows.
