Curtain Walling

 Curtain walling is a non-structural exterior cladding system comprising lightweight aluminium frames and glass panels. It is designed to provide an aesthetically pleasing and functional enclosure for buildings, offering protection against weather elements.

Curtain walling offers several benefits, including:

• Enhanced aesthetics and modern architectural appeal.
• Improved energy efficiency through thermal insulation and solar control.
• Increased natural light and views with the use of large glass panels.
• Structural integrity and resistance to wind, water, and other environmental factors.
• Flexibility in design, allowing for creative and customizable solutions.
• Easy integration with other building systems such as ventilation and fire safety.

Curtain walls are available in various types, offering unique features and design possibilities. The main types of curtain walls include:

1. Stick-Built Curtain Walls: This is the most traditional and widely used curtain wall system type. It involves assembling the frame on-site using individual components, including mullions (vertical framing members) and transoms (horizontal framing members). The glass panels are installed into the frame, allowing for flexibility in construction and customisation.

2. Unitised Curtain Walls: Unitised curtain walls are pre-fabricated panels assembled off-site and transported and installed as complete units. These panels typically consist of the frame and the glazing, including glass, spandrel panels, and other materials. Due to factory fabrication, unitised curtain walls offer faster installation times and improved quality control.

3. Semi-Unitised Curtain Walls: Semi-unitised curtain walls combine the benefits of both stick-built and unitised systems. In this type, certain sections of the curtain wall are pre-fabricated as units, while other sections are built on-site. This approach allows for a balance between customisation and efficiency in installation.

4. Point-Supported Curtain Walls: Point-supported curtain walls utilize glass panels directly connected to the building structure using point-fixings, such as tension rods or bolts. These fixings are strategically placed at specific points on the glass, allowing for a visually stunning, minimalist appearance with uninterrupted views.

5. Structural Glazed Curtain Walls: Structural glazed curtain walls eliminate the need for visible framing elements by incorporating the glass panels directly into the building structure. The glass panels act as both the cladding and the structural support, providing a seamless and highly transparent appearance.

6. Custom Curtain Walls: Custom curtain walls refer to bespoke systems that are specifically designed to meet unique architectural and performance requirements. These systems can combine different materials, shapes, sizes, and features to achieve the desired aesthetic and functional outcomes.

It's important to consult with our curtain walling specialist or an architectural professional to determine the most suitable type of system for your project, considering factors such as design intent, building requirements, budget, and desired performance characteristics.

Curtain walling systems are versatile and can be used in a wide range of building types, including commercial offices, residential buildings, educational institutions, healthcare facilities, and more. They are especially popular for buildings with large facades or complex architectural designs.

Yes, curtain walling systems are designed to provide thermal insulation and contribute to energy efficiency. They incorporate thermal breaks and insulating glass units to minimize heat transfer, reducing the reliance on heating and cooling systems and lowering energy consumption.

The installation time for a curtain walling system depends on various factors such as the size and complexity of the project, the building structure, and the chosen materials. A professional curtain walling specialist will assess these factors and provide a timeline specific to your project.

Regular maintenance is essential to ensure the longevity and performance of curtain walling systems. This may include inspection of seals, gaskets, and drainage systems, as well as cleaning of glass panels and frames. It is recommended to consult with the manufacturer or specialist for specific maintenance guidelines.

Curtain walling systems can be designed to meet fire safety regulations and requirements. Fire-resistant glass and fire-rated framing systems can be incorporated into the curtain wall design to enhance the building's fire protection.

Yes, curtain walling systems can provide acoustic insulation, reducing noise transmission from the external environment. By using double or triple glazing and appropriate seals, curtain walling can contribute to creating a quieter and more comfortable indoor environment.

Yes, curtain walling systems offer a high degree of customisation. They can be tailored to match the unique design requirements of a building, including different glass types, frame finishes, sizes, and configurations. Working with a professional curtain walling specialist allows you to create a bespoke solution for your project.

When selecting a curtain walling specialist, consider factors such as their experience, expertise, reputation, portfolio of completed projects, and compliance with industry standards. Request references and testimonials, and ensure they have the necessary certifications and insurance. A reputable specialist will provide expert advice and guidance throughout the entire process.
