Windows are so important when designing or renovating your home. They connect the inside with the outside and offer style and security, but they can also provide energy efficiency and functionality. Double glazed windows carry many benefits, as well as being an attractive addition to your home. Originating from England and also known as insulating glass, double glazed windows consist of 2 or 3 window panes separated by a vacuum filled space to reduce heat loss.

Why Should I Choose Double Glazed Windows?

The top reasons to choose double glazed windows in your home include:

  • Reduced heat loss and gain
  • Energy efficiency
  • Make Your Home Quieter
  • Environmentally Friendly
  • Condensation Free
  • Reduced Heat Loss and Heat Gain

Double glazed windows work in the same way as insulation in your roof and walls with the space between the two panes of glass stopping heat from being released. The area between the glass is so small and the trapped air, which is already a poor heat conductor, cannot circulate. In winter, this results in your warm air being trapped inside the home and preventing stinging heat from penetrating your cool rooms in summer.

Energy Efficiency

Good quality double glazing reduces heat loss, keeps the home warmer or cooler and reduces your heating and cooling bills. The initial cost to install double glazed windows is significantly offset by the potential savings made by the reduced energy required. Double glazing can also negate the requirement for heavy-duty curtains that would previously be used to attempt to keep the heat and cool inside.

Environmentally Friendly

The decreased carbon emissions resulting from reduced energy expenditure in heating and cooling your home mean that double glazing contributes significantly to the conservation of valuable resources.

Make Your Home Quieter

Are you a shift worker with noisy neighbours? Or do you live on a busy street? Block out the noise with double glazed windows without compromising on your view. The thicker, laminated glass and the gap between the two panes provide acoustic insulation, all while still looking functional and stylish.

Condensation Free

Water drips, condensation and resulting mould and mildew come with single pane windows and can make your family very unwell and are a pain to clean without harsh chemicals. Double glazing reduces thermal conductivity, making your windows dry and warm. This means there is no cold surface for the moist air to form condensation.

Why Should I Choose Double Glazed Windows?

Double glazed windows can be a sound investment for your home and the comfort of your family. As with all quality products, adding double glazed windows to your property may increase its value and street appeal as well as reducing energy costs and your carbon footprint.

You know your home needs doors, but when it comes to choosing the right style and size for the opening, you’re definitely spoilt for choice. With passing fads comes developments in functionality and revamping of old favourites but bottom line is, you want quality doors offering thermal efficiency and ventilation, security and a stylish look that won’t date.

So what can you expect to choose from?

  • Front Doors
  • Back Doors
  • French Doors
  • Sliding Doors
  • Security and Flyscreen Doors

Front Doors

Whether it be a solid fire-engine red or a glass panelled timber frame, the front door is one of the focal points of the ‘face’ of your house. Choosing the right style of door to suit the façade of your home is vital to ensure it only stands out for the right reasons. The range of Heatseal UPVC front doors can not only provide a suitable choice for your front opening, but can also include security devices to ensure you feel safe inside your home.

Back Doors

Arguably not as noticed as the front door, the back door needs to be functional, secure and suit the exterior of the home. Your back door needs to be able to withstand frequent wear and tear from pets, children, weather and outdoor elements as they are generally less protected than other doors.

Sliding Doors

A popular choice for not only the exits of the home, sliding doors can greatly improve aesthetics whilst being highly functional, solid, secure and great value. Replacement sliding doors can be a cost -effective way to rejuvenate tired sliders and older, large door openings. They are also great for smaller outdoor spaces as they do not open inwards or outwards, thus eliminating the need for free space to allow for the door.

Flyscreen and Security Doors

The ultimate in security whilst keeping bugs and vermin out, the flyscreen and security door is a highly popular option for both doors and windows in most Australian homes. Take advantage of a summer breeze without the flies with flyscreens on your back and front door and allow the air to flow through. Combine your flyscreen with security measures and you’ll be safe and secure.

What Kind Of Door Should I Choose?

You can’t have a home without doors, so why not choose the very best quality from the affordable range at Heatseal? Based on popular European functionality, Heatseal windows and doors have been specifically manufactured for the Australian climate and priced to allow you to choose easily.

At Heatseal, we pride ourselves on our extensive range of WINDOW styles. We offer a superior window consultancy service and can build custom sized windows for any size and shape to suit your needs and personal style.

Our window designs include:

Awning Windows
Casement Windows
Fixed Windows

Security
Awning and Casement
A very popular choice and for good reason, awning and casement windows provide extensive ventilation with a measure of weather protection. Stylish and functional, awning windows open out from the bottom and casement open out like traditional shutter-style.

Heatseal’s range of UPVC Double Glazed Tilt & Turn Windows offer a modern, innovative design to help you make the most of the change in breeze direction as well as being incredibly energy efficient and extremely secure.

Fixed
Fixed windows are an effective, inexpensive way to let light into your home and can be designed to run from floor to ceiling, to act as a large feature wall and make the most of a stunning view, or be a simple, small opening to allow light into a very small area.

Corner and Bay
Adding a bit of elegance to the face of your house and a bit more space in the room they occupy, corner and bay windows ‘wrap around a corner’ or protrude into the awning space to bring light, and the view, in.

Security
Your home is your greatest investment and you want to keep your family safe. Protect both with security windows and doors from Heatseal and let beautiful, fresh air be the only thing coming into your home.

Plus we can install Flyscreens
Installing flyscreens with your windows ensure you allow the breeze in and keep the bugs and small creatures out of your home. We can even install retractable flyscreens to your awning and casement windows and to your standard tilt and turn window.

You can’t have a house without WINDOWS, and whilst they may seem like one of the easier items to choose when designing or renovating your home, selecting the right type of windows is important, especially when it comes to thermal regulation. Windows severely impact how hot and cold your home feels in extreme temperatures, with up to 40% of a home’s heating energy being lost and up to 87% of heat let in through windows.

Some aspects to consider when choosing your glazing method include:

Local Climate
Building design and materials
Size and location
Local Climate
Where you live will determine what materials you choose when you build or renovate your home. Extreme temperatures such as snow in winter and blazing heat in summer need to be considered when choosing windows, as the cold and heat from these weather conditions come directly into your home through your windows. Choosing double glazed windows not only provides thermal regulation from these extremes but also protects from wind and humidity if these are factors in your local area.

Building Design and Materials
The layout, form and orientation of your building will all affect your window choices as the position and heat from the sun will need to be considered. Nobody wants a roasting bedroom or the glare from the setting sun coming through to the kitchen. The heat impact can be reduced by selecting double glazed windows however this light/glare factor still needs to be considered.

The materials you use in your home, such as wall construction and roof/wall insulation will also impact the thermal regulation of your home. Attempt to compliment your windows and house materials to get the best thermal regulation benefits.

Size and Location
The size of your home will be a factor, as small homes heat up quickly and, dependant on the type of insulation and windows chosen, can take a long time to cool down. Large homes are quite the opposite, with more heating methods required and often being quite cool. Lots of windows in either size home can be a lovely addition, however double glazed is always the best option as they are environmentally friendly and manufactured for thermal advantages.

If you're looking for an insanely solid windows and frames to sound proof or insulate your house then look no further. These guys are absolutely amazing to say the least. Their products are also well and truly above and beyond what you'd expect and the entire process has been nothing but amazing. Can't thank the team enough for all their work.

As far as my use case goes, I have quite a large hifi and seperate cinema system which can get insanely loud so I needed some serious glass to help keep the noise contained and this goes above what I was expecting. Anyone who's serious about their cinema needs to give these guys a call.

We had Heatseal install windows and doors at our previous home and we knew that the double glazing worked and was very efficient. We have found in our new home that the early morning temperature in the lounge area has been reduced by a good 5 - 10 degrees due to the new windows. Nathan, who did the job, was very efficient, a clean worker, friendly and eagerly helped us move furniture. 10/10 for the whole team.

We’ve had several jobs undertaken by Heatseal, from replacement of several of our window frames and a door cut into a wall to access a new outdoor patio area.

Regarding the door, we went in wanting a French door but were unable to go with this due to space/engineering challenges. Paul went through our options to get something that was suitable for our needs and he has a sixth sense to provide a product that went above and beyond what I had imagined we’d end up with.

With our windows, we had our hearts set on the European style tilt and turn frames, something that’s a rarity in Australia and Heatseal were one of the few installers that offer this option. Not the cheapest way to go, but the quality and functionality was well worth it.

I can’t recommend highly enough the level of quality and service from Heatseal.

After considering upgrading our older windows in the kids bedrooms to double glazed for years, experiencing the Bunbury tornado in 2024 quickly made that decision immediate. And what a shame we hadn't done it 10 years ago... the noise reduction, heat insulation is truly remarkable and the kids are now back sleeping through the night in their own beds. The fitting to the older frames was seamless, look great and all round service has been excellent. A real game changer for us, thanks Heatseal Bunbury
