Energy efficient windows

Energy Efficient Windows and Doors

Double glazing is an excellent investment for your Sudbury home, offering reduced energy bills and improved insulation. By upgrading to A-rated double glazed windows, you could save up to £160 per year on energy bills, as confirmed by the Energy Savings Trust.

At Infil, we are committed to providing reliable and durable double glazing solutions for our customers. In Sudbury, we only install independently verified BRFC A-rated windows that meet the highest standards of insulation.

For homeowners in conservation areas, we understand the challenges of finding double glazing solutions that meet local building regulations.

That’s why we offer a range of period designs and wood effects that comply with these regulations while also providing effective insulation. If you live in a protected listed property, we also offer secondary glazing solutions to help retain warmth. Our goal is to provide every homeowner with a warm and comfortable double glazing solution that meets their needs.
