Single-glazed windows on older or period properties are not made using
low-emissivity coated glass and do not offer energy-saving benefits; the
same goes for the old-style double-glazed units. Save money on monthly
bills and increase thermal insulation with double or triple-glazed
windows that prevent heat from escaping your home. Depending on
your requirements, we will advise you on the best way forward in
upgrading your windows and doors.
