National fabricator Listers has developed an online energy-saving calculator. The tool was created to help installers sell premium windows and doors as the cost of energy increases.
The calculator illustrates the potential energy-saving benefits to homeowners of upgrading their windows to modern, efficient alternatives from Listers. Hosted on the fabricator’s own website, or available to retail companies to host on their own websites as a plug in, the energy calculator is said to have a user-friendly interface that encourages homeowners to compare a modern window installation with their current set up. The result is a potential cost saving alongside a likely reduction in carbon emissions.
Quick payback
The energy calculator uses estimated U-values for older windows, the published U-values for Listers’ energy-saving products, the home’s glazed area and the price of energy to determine likely cost savings. In a typical example, a homeowner in an electrically heated semi-detached property who replaces single-glazed PVC-U windows with double-glazed Veka windows from Listers could save £15,290 over 10 years, and reduce carbon emissions by 28,760kg. The price of the windows would be in the region of £8,000.
“Right at the top of the news agenda, and driving a lot of today’s window and door buying decisions, is the cost of energy,” said Roy Frost, Listers’ managing director. “Insulating homes and reducing energy usage are key for many households going into 2023, as the risk of further hikes in energy bills is very high. A typical home upgrading their windows today could see their investment paid back in just five years. This is a powerful sales message as the market contracts.”
