How much money will energy efficient windows save me on heating costs?
A reduction of up to 70% less heat loss is possible when you upgrade from old single glazed windows or inadequate double glazed windows to the latest A-rated energy efficient windows.
For owners of a typical semi-detached property, savings can amount to about £100-£300 each year. Bigger savings are achievable if your home is detached or especially large because of the increased window sizes and higher energy demand.
Factors such as U-values, airtightness and what insulation currently exists will also impact accrued savings.
Is the casement, sash or tilt & turn style the most efficient?
Sealing plays a big role in the standard of energy efficiency offered by the various window types. A thorough explanation of draught proofing windows and the best energy efficient windows can be given by one of our expert window advisors.
As they close tightly, casement windows and tilt & turn windows do an excellent job of restricting draughts and heat loss. A downside of traditional sash windows is that they leak more air.
Reduced heating bills and elevated comfort is a certainty when you prioritise well-sealed, high-performance windows.
Learn how A, B, and C-rated windows differ
Energy efficiency between A, B and C-rated windows varies, as acknowledged in the Window Energy Rating (WER) system.
A-rated windows are top of the tree for energy efficiency, providing outstanding heat retention and lessening the need for heater usage. C-rated windows can be bought more cheaply, but they don’t rival A or B-rated windows for performance and they’re the minimum accepted energy rating to comply with UK building regulations.
If you were to upgrade from C-rated windows to A-rated windows, you would feel far fewer draughts, much greater warmth and enjoy a healthy drop in energy bills.
Why U-values are so significant
U-values are separate from WERs and should be taken into consideration when purchasing window replacements. A U-value tells you how much heat escapes through a window (low U-values denote high-level insulation). Typical ranges are:
- Single glazing: 5.0–6.0 W/m²K
- Old double glazing: 2.8–3.0 W/m²K
- Modern A-rated windows: 1.2–1.6 W/m²K
To be assured of accelerated comfort and more affordable energy bills, just observe the WER ratings and U-values of any windows that you come across. Amber’s window assortment delivers peak all-round performance and is worth exploring at our Norwich showroom.
