When the temperature drops, windows are often the biggest cause of heat loss. Luckily, there are plenty of ways to improve insulation without replacing your glazing.
Millions of houses in the UK were built before 1900, with sash windows that are notoriously prone to draughts. Householders frequently replace them with uPVC windows, but sash window repair is an alternative that improves heat efficiency while maintaining the Victorian aesthetic. This is a service provided by dozens of specialist providers like //www.sashwindowpreservation.co.uk/services/sash-window-repair/.
While you’re considering your options, here are some easy fixes to be going on with.
Thermal curtains and blinds
These are among the simplest upgrades. Made from multiple fabric layers or honeycomb-style pockets, they create a thermal barrier between the cold glass and your room. They work best at night, slowing heat loss and keeping spaces snug, although they can’t fully block draughts.
Bubble wrap
For temporary insulation, lightly mist your windows with water before pressing bubble wrap onto the glass, bubbles facing inward. The trapped layer of air mimics the effect of window film.
Draught excluders
Place excluders along sills for a low-cost way to prevent floor-level draughts.
Magnetic secondary glazing
This is a longer-term remedy. Removable panels attach via magnetic strips to form an insulating air gap, which is perfect for period homes and listed properties.
Low-emissivity glazing
A low-E coating reflects heat back into the room but usually demands the installation of new windows.
Together, these smart measures will make your home warmer, more comfortable and more energy efficient this winter.
