Revitalise your home with new windows and doors

Whether you're undertaking a full home renovation or prioritising changes to your home that will have the biggest impact, updating the windows and doors in your existing home is a proven way to increase the comfort, aesthetics, and value of your home. Say goodbye to the poor performance and on-going maintenance of your aging joinery. New windows and doors can change the way light, sound, and fresh air move in and out of your home.

When it comes to upgrading the windows and doors in your home, there are two options to consider, each with their own benefits. We’ve put together a useful guide to help you understand the differences and find the best solution for your home.

How to know it's time for new joinery

Climate control

New windows and doors eliminate draughts, making your home more comfortable and healthier year-round.

Compromised safety

Windows and doors that are broken or do not close properly should be replaced or repaired immediately to keep your home safe and secure.

Enhanced aesthetics

Your windows and doors are one of the most notable features of your home, changing the colour or configuration will upgrade your curb appeal while also enhancing the energy efficiency.

Exterior sounds

If your windows aren’t offering enough protection from exterior noises, you may need to replace them. Single-glazing will transfer sound vibrations from the outdoors into your house more easily than double-glazing.

Lack of natural light

Many older homes were not designed to allow adequate light. There is nothing worse than a dark and dreary home, invite more daylight into your room by enlarging your existing windows or positioning new ones to take full advantage of the available light.

Lower power bills

Older homes with single-glazing lack proper insulation, causing your air conditioning or heating systems to work harder. Double-glazing is more energy efficient and designed to help prevent heat transfer inside and outside of your home.

Water damage

Water between glass panes, leaking, water stains or evidence of rot can be signs that excess moisture is accumulating where you cannot see it.

Update options

Replacement windows and doors

Existing joinery is removed entirely and a new window or door and framing structure is installed allowing you to completely change the colour, style and configuration.

Replacement windows may be a good option if:

  • You’d like to completely change the size and shape of your windows and doors
  • Your window frames or sills are in poor condition or show signs of rot
Insert windows

In this method, a new window is inserted into the existing timber window frame allowing you to update the colour and configuration of your windows while retaining the character of your home with minimal disruption to your home.

Insert windows may be a good option if:

  • Your wooden joinery is a bit draughty, stiff to open and close but in reasonable condition
  • You’d like to retain the existing character of your house
  • You’d like to improve the function and thermal performance of your joinery

Update for a warmer, healthier, more efficient home

With replacement or insert windows and doors you have the opportunity to bring the thermal performance of your joinery up to current building code standards and enjoy a healthier home. A healthy home is warm, comfortable, and cost efficient to run with minimal impact on the environment, not to mention your family will experience greater wellbeing and productivity. In order to achieve a healthy home, thermally efficient design and product choice are important; consider thermally efficient windows and doors like ThermalHEART® or Klima® with high performance Low-E glass such as The AGP System®.
