Guide to Windows

Looking into windows

Like doors, windows play an essential role in any home. More and more home owners are acknowledging the immense importance of windows and the overall look and feel they generate in their home.


We don’t always think of all the benefits windows provide us with, such as:

  • 1. Offer cross ventilation throughout your home and allow you to control that ventilation

  • 2. Bring natural light into your home

  • 3. Enjoy the view of the locality

  • 4. Prevent a home from looking gloomy

  • 5. Prevent a home from feeling stuffy

  • 6. Enhance the visual appeal of the house

  • 7. Increase the Value of your home

    Window problems – air leakage

    Air leakage occurs when gaps and cracks start to appear around your windows, when the glass becomes loose and from other sources of aging. This means you lose control of ventilation in your home. The higher the air leakage the more difficult it is to control the inside temperature of your home resulting in high energy bills.


    5 Reasons why air leakage and controlling ventilation through windows matters:

    • 1. They are often the highest driver of energy loss – between 25% - 70% depending on the type of windows and their condition.

    • 2. Can be a major factor to draughts in both hot and cold temperatures.

    • 3. Can lead to moisture problems creating mold and mildew inside your home.

    • 4. Dust, smoke and other air pollutants will enter, leading to poor quality, unhealthy air in your home.

    • 5. An invitation for insects, rodents and other pesties to enter you home again contributing to unhealthy conditions.

    How to find window draughts – air leakage

    To draught proof your home you firstly need to find the draughts or where the air is leaking in.


    How to find draughts and air leakage around windows: 

    • * Look for obvious gaps - Visible light under and around the windows is a good clue

    • * Feel for moving air - Feel around the windows for cold air in the winter time and hot air in the summer time.

    • * Look for curtain movement - When the windows are closed and it’s a windy day look for the curtains moving – this will be a key indicator

    • * Listen for rattles or whistles – when it’s very windy listen for rattles and whistling around your windows.
