Energy Saving Windows and Doors is the leading aluminium double glazed bi-fold windows and doors system manufacturer suitable for modern and traditional homes.

Well-designed and installed double glazed bi-fold doors not only magnify your view but provides ample airflow when opened fully.

The Best Aluminium Double Glazed Bi-Fold Doors in Sydney

Aluminium double glazed bi-fold doors are the number one choice for our customers because of their style and functionality.

We use aluminium or thermally broken aluminium as they are the best materials for a secure, robust, long-lasting window and door system and give an exceptional architectural finish.

Our double glazed bi-fold doors are fully bespoke and are available in a wide range of configurations to deliver the perfect solution for your home. You can also add a retractable screen option that fits seamlessly.

Our double glazed bi-fold doors also require very low maintenance. Not only are they resistant to deterioration, but we also use quality Dulux and Akzo Nobel powder coating finishes at our in-house manufacturing facility.

Our aluminium double glazed bi-fold doors can achieve a U-value (insulation measure) to suit your needs. Low-E glass combined with argon gas creates a thermally efficient product.

It saves energy and lowers your energy bills by keeping your home cool in summer and warm in winter and curbs the estimated 80% of your energy bills from going out your windows.

They also have a weather-sealed threshold which helps to protect against the weather and ensure an increase in thermal performance.

No need to have huge steel beams fitted to carry the weight of a double glazed panel that can weigh up to 100kg each. Multiply that by six so panels can weigh over half a tonne.

Our door panels run on heavy-duty bottom rollers, and their weight is supported at the sill, which makes our double glazed bi-fold doors an excellent choice for renovations or where overhead support isn’t available.

Opening the bi-fold panels is as easy as opening your car door. Virtually no drag at all. And with no obstructing frames or beams, you can stack the doors discreetly.

All our aluminium double glazed bi-fold doors are equipped with a unique lever compression locking system equal to or exceeding the latest industry standards. The heavy-duty aluminium hinges can withstand attacks even from the most determined intruders.

How does a double-glazed bi-fold door work?

How a double-glazed bi-fold door works depends on the type of material used in each panel. For example, some types of plastic can be shatterproof, while others are more likely to shatter under impact. 

Some types of wood may provide additional durability while others may be more susceptible to moisture and rotting. Choosing the right combination of materials for your particular situation will help ensure that your door will function properly and protect you from unwanted outside elements.

Benefits of using a double-glazed bi-fold door

A double-glazed bi-fold door is a highly effective way to reduce heat loss and increase insulation in your home. These doors are made of two layers of glass separated by an air gap. The outer layer of glass is firmer, giving it more structure and strength, while the inner layer of glass is softer and more flexible, allowing it to deform more easily. This allows the door to effectively block wind and sun penetration but still let light into your home.

Additionally, a double-glazed bi-fold door has a much higher R-value (insulation efficiency) than single-glazed doors, which means it can significantly reduce your energy costs. In most cases, you will also notice a significant improvement in soundproofing as well, since the air gap between the two layers of glass allows for better acoustic isolation. Overall, using a double-glazed bi-fold door is a great way to improve your home’s energy efficiency, comfort, and soundproofing.

How to choose the right size for a double-glazed bi-fold door

Choosing the right size for a double-glazed bi-fold door is an important step in ensuring that it fits your home properly and provides optimal insulation and weather-resistance. While there are several factors to consider, the main ones include the size of your home, the type of door, and the overall style and design of your home. 

Follow these guidelines to pick the correct size.

If you have a small home with a single entrance or window, a small-sized door may be a good fit. For larger homes with multiple entrances or windows, large-sized doors may be more appropriate.

If you have a traditional style home with many windows and doors, a standard-sized door may work best. On the other hand, if you prefer more modern styles, a high-security or extra-secure door may be needed.

If you want to maximize energy efficiency and reduce your carbon footprint, consider installing dual-glazed doors that use both glass types (e.g., low-E glass) when possible. In addition to providing greater protection from the sun’s heat, light, and glare, dual-glazed doors also provide additional insulation against cold temperatures.

My view is that when one requires constant supply of a good product or service, it’s vital that the supplier is a “specialist”. And that’s where Tim and his team at Energy-Saving Windows excel. As the owner, Tim brings decades of experience to the table when it comes to windows and doors - and this means we benefit from saving time and money. Their products are exceptional and their client liaison is probably the best of any company I’ve dealt with. I’d highly recommend them.
