Our double glazed window systems can help counter the negative effects caused by the gaps around existing windows

Stop window drafts with this efficient window draft stopper

The heating and cooling loss from an unsealed home, via drafts through gaps around doors and windows, can be up to 15%. This is equivalent to removing a few bricks from your wall! And with the rapidly escalating cost of eletricity & gas, now it is even more important than ever to stop drafts fom windows.

It is also important to remember that a window allowing airflow around it will be a poor insulator, no matter what its materials and construction.

Drafty windows affect your comfort

Drafts through & around your windows can create cold spots in the room, particularly around the legs and feet. As a result internal heating is normally turned up higher than necessary to compensate & even the cat or dog will want to jump up on the couch to snuggle next to you for warmth.

The tight tolerances designed into our secondary window glazing plus the fact that we completely seal around the new frame means that we keep both the hot & cold air and dust out, whilst retaining the cool or warm air in the building.


Extensive use is made of air-conditioning in today’s busy offices, shops, and at home. Installing secondary glazed windows & doors will provide energy efficient windows that will help to reduce the energy used in heating or cooling your home, house, office or apartment due to its improved insulation properties.

Secondary Double Glazing also stops warm or cool air escaping around your windows through the elimination of drafts from around windows frames.

The Problem

For doors and windows to function they must have gaps between their edges and the frame. These gaps allow for installation & accommodate the normal & natural movement of the building.

But … these gaps can also allow the intrusion of :

  • Noise
  • Smoke
  • Moisture
  • Cold drafts
  • Dust and embers
  • Light
  • Insects and vermin

And the leakage of:

  • Hot air in winter, thus increasing your heating costs: &/or
  • Cool air in summer, thus increasing your air conditioning costs.

Air Permeability Test

The following Air Permeability Test results graph clearly shows just how effective our secondary double glazing is as a window draft stopper for stopping drafts around your windows.

Air Permeability Test Results for Secondary Glazed Windows
Line C above shows that Secondary Double Glazing is 4 to 5 times better at stopping window drafts.

Tha Air Permability Test defines the ability of a window to resist air penetration when it is subjected to differential pressure, and is a measure of the air which seeps through the test window at various given test pressures.

The average amount of air which leaks through a metre of the opening weather seal (as seen from the inside of the window) is measured and the measurements are calibrated in cubic metres (m 3), per hour, per metre of opening seal. A two panel slider 1215 W x 1193 H was fitted to a test rig at BSI in Hemel Hempstead.

The chart shows that as compared to a standard window (A & B), our secondary glazing offers a substantial reduction in air seepage at all pressures (C).

In essence, the graph above shows that secondary double glazing is 4 to 5 times more effective at stopping drafts around windows.

The Solution

If you have an existing property, house, home, apartment, flat or office & want or need to stop window drafts, secondary double glazing is the best answer.

Secondary double glazing can prevent the impact of gaps around the frames of your existing windows. This is because we install a completely sealed new window on the inside of your existing window using a flexible silicone sealant & thus we can effectively stop window drafts as there are no longer any gaps or drafts!
