Thermally Insulated Aluminum & Timber
Bi-fold Door System

Our original hybrid system, the AW73 Solid Engineered Hardwood Timber Bi-Fold Door delivers the best of both worlds - natural character and warmth of timber to the inside and the modern benefits of aluminum to the outside!

10 Year Manufacturers Warranty

10 Product Warranty


The AW73 system is our most popular hybrid bi-fold door to date with thousands of installations worldwide. By combing both our timber and aluminum systems together, we created the ‘AW73’ system.

It’s essentially an aluminum system which is clad internally with hardwood timber (European Oak), and so presents qualities of both materials; with the warmth and character of natural timber and the low maintenance, strong, durable properties of aluminum.

This combination proves extremely popular as it achieves a clean modern look to the outside of the building and a more traditional sympathetic appearance to the internal decoration of the property.

The AW73 is custom made to your exact requirements - meaning you get to specify; dimensions, product style, opening style, configuration, color, finish, hardware, thresholds, glass specification, glazing options, magnetic stops, ventilation and internal blinds, and is equally ideal for both residential and commercial use.

The thermally broken profile provides a product that is thermally efficient and will help ensure your home stays the right temperature throughout the year, keeping your heating and cooling bills low, saving you money.

A matching range of windows and door products are available to complement the AW73 bi-fold door.

But for the many, the most popular option is our flush threshold that blends the inside floor with the outside floor, especially those with children, elderly or wheel chair users.

Our flush track is ADA compliant, fully weather-rated and the profile itself is available in a choice of 2 colors / finishes; anodized silver (standard) and bronze.
