Windows and external doors are often sources of draughts. They allow warm air to leak out of your house constantly to be replaced by colder air which you have to heat to remain comfortable. So it’s a good idea to block up the draughts.



Windows and external doors are often the weak link when it comes to keeping our homes warm. Single glazing, poor seals and cracks can all add significantly to a loss of heat and discomfort.  These faults can often be fixed quite simply.

What is magnetic secondary glazing?

A sheet of plastic on the inside of your window, which can be easily put up and down because it's held on by strong magnets.This is a good, lower cost way to stop cold getting in your windows - and it can be used in listed buildings and conservation areas because it makes no change to the building.
