High Performance Commercial Aluminium double-hung windows

Awnings are not only a great way to add curb appeal and value to your home, but they also have the potential to reduce your energy costs. Fixed windows are another excellent way to improve the energy efficiency of commercial space. 

By preventing solar heat gain, fixed windows can help to keep the building cooler in the summer and warmer in the winter.

    The WJW range of windows

    The WJW Aluminum range of windows and doors is designed to provide the strength and performance required in high-end architectural applications. The 125mm framing system is significantly stronger than conventional systems, allowing for large semi-commercial configurations. 

    This gives you the best of both worlds - the strength and stability of a commercial system with the aesthetic appeal of a residential system. The WJW system incorporates several features that make it ideal for use in high-end applications. The most significant of these is the inclusion of a thermal break. It helps to reduce heat loss through the frame, making the system more energy efficient. It also helps to reduce condensation and frost build-up, making it ideal for use in cold climates. The WJW Aluminum system is available in various finishes, including powder coating and anodising. This gives you the flexibility to create a unique look for your project.

    The WJW100 Awning & Casement window system features smooth flat sash profiles, an integrated bead line, and a rounded nose to achieve a modern yet classic appearance. This same feature is carried through the WJW100 Hinged Door systems to deliver a unified aesthetic throughout the range. 

    Capable of accommodating extensive high-performance double glazing and able to achieve single sashes of up to 2400mm in height, the WJW100 Awning & Casement represents a class of its own in style and performance. 

    The powder coating option also provides a high level of protection against UV damage, making it ideal for use in harsh environments. This system is ideal for those looking for a sleek and stylish window or door that doesn’t sacrifice functionality. The WJW100 Awning & Casement is perfect for new build and renovation projects.

    1Q: What is an aluminium awning window?

    A: An aluminium awning window has hinges at the top of the frame, and swings outward from the bottom. They can open with the simple crank of a handle or with the basic glide of the Easy-Slide Operator hardware. Awning windows are great in places that could use extra ventilation and light

    2Q: How secure are aluminium awning windows?

    A: Aluminium Awning windows are commonly secured by a keyed lock that is integrated into the winder mechanism (which we supply as standard hardware), which allows the window to be locked in a partially open position although fully shut is always more secure.

    3Q: Do aluminium awning windows allow airflow?

    A: Not just for kitchens, an aluminium awning window can optimize light and air flow in any room—and in all weather. Its frame opens outward to let breezes in while keeping moisture out and-because it's hinged at the top-that means it can even ventilate your house in heavy rain!

    4Q: What are aluminium awning windows good for?

    A: Aluminium Awning windows can be placed higher on walls than many other types of windows. High window placement is useful for capturing natural light and ventilation while also maximising your wall space and maintaining privacy. Awning windows offer superior privacy options to other openable windows.

    5Q: What is the difference between a casement and aluminium awning window?

    A: The key difference between aluminium casement windows and aluminium awning windows is where they are hinged. Casement windows hinge at the side, whereas awning windows hinge at the top. Both types of windows open fully outward, making either of the styles a great choice when you want lots of ventilation and natural light.
