Cut Heating Costs with Energy-Efficient Double Glazing
Did you know that up to 25% of a home’s heat is lost through windows? Installing energy-efficient double glazing can reduce this heat loss by up to 75%. In a typical three-bedroom detached home, replacing outdated windows could save up to £160 a year on heating bills. A well-insulated home not only lowers energy consumption but also reduces CO2 emissions, making it an eco-friendly choice.
Crown Windows provides high-performance double-glazing solutions tailored to your needs. All our windows are designed to keep your home warm and secure while enriching its aesthetic appeal.

How Does Double Glazing Improve Energy Efficiency?
Double glazing works by trapping air between two glass panes, creating an insulating barrier that reduces heat loss. This helps maintain a comfortable indoor temperature, cutting down on heating costs while keeping your home warm during colder months.
