With energy prices on the rise, homeowners across the country are more conscious than ever of keeping their homes warm and reducing the impact of rising energy bills.
If you’re considering replacing your old, draughty windows in the near future, investing in the right solution will ensure optimal energy efficiency, leading to a cosier home and lower heating costs for years to come.
With so many options available, Crown Windows are pleased to share over 20 years of industry expertise to help guide you through the best energy-efficient window choices.
How do house windows impact energy efficiency?
The efficiency of your windows plays a crucial role in heat retention. With up to 25% of a home’s heat being lost through its windows, upgrading to replacement uPVC windows with high-quality frames and glazing can make a significant difference in reducing energy consumption. Installing new double glazing or even triple glazing ensures less heat escapes, keeping your home warm in winter and cool in summer.
What factors determine the energy efficiency of windows?
At Crown Windows, our uPVC window frames are designed to prevent cold transfer, maintaining a comfortable temperature inside your home.
Our casement windows, including modern flush casement windows, are available with advanced double and triple glazing. These panes are separated by argon gas, which significantly reduces heat transfer and boosts energy ratings. Additionally, we offer low-e glass, a specialised option with a microscopic coating that enhances insulation, improving your window energy rating even further.
How is the energy efficiency of windows measured?
The energy efficiency of house windows is measured by their U-value – the lower the U-value, the better the insulation. Older single-glazed windows often have a U-value exceeding 4.8, whereas our high-performance triple-glazed windows, featuring low-e glass and argon gas filling, can achieve an impressive U-value as low as 0.8.
Choosing energy-efficient replacement uPVC windows with low U-values provides long-term benefits, including a warmer, less draughty home, lower heating costs, and a reduced environmental impact.
