Window Insulation - GreenSide Energy Solutions

Window Insulation


Between 21-31% of heat loss in a home is lost through windows!

Draughts and air leakage around windows increase your heating costs.

If heat can be lost through a solid ceiling, underfloor or wall, imagine how much is lost through open gaps around windows!

If you’ve already insulated your ceiling, underfloor and walls or if you’re on a tight budget, there are other things you can also do to make your home a more comfortable place to live in:

  • Plug up draughts around windows and doors.
  • If you have a fireplace, block the chimney when not in use.
  • A cheap alternative to expensive double-glazing is fixing bubble-wrap on the windows of particularly cold rooms throughout the house. Bubble-wrap is a cheap, quick and efficient temporary solution!
  • Use thermal drape curtains rather than blinds to keep the heat in.
  • Fresh air circulating through the house helps stop condensation and dampness.
  • Use exhaust fans to remove excess moisture from kitchens, bathrooms and laundry rooms.
  • Dryers should be vented to the outside, not into the ceiling cavity.

After we’ve assessed your home, we’ll let you know which affordable options will suit your windows.
