In the dynamic realm of architectural design, perforated metal facades have emerged as a versatile and visually striking choice, offering architects a myriad of possibilities. At Supply Bay Metals, we understand the unique challenges presented by tropical climates and are dedicated to providing solutions that marry aesthetic appeal with practical considerations. In this blog post, we answer commonly asked questions by architects and designers about perforated metal facades.

1.What are the practical advantages of perforated cladding?

The primary benefit of perforated cladding is that is allows architects and designers to control the influx of natural light and ventilation within a building. The use of large perforations facilitate the passage of ample natural light and airflow, reducing the dependence on air conditioning systems, which is particularly important for tropical climates in Singapore and Asia.

The design of perforated metal also mitigates the risk of water retention, preventing potential issues associated with humidity, such as rust or degradation. Additionally, using finishes such as Powder coating or Fluorocarbon (PVDF) coating, architects and designers can ensure that the perforated cladding maintains its functionality and visual appeal with minimal maintenance requirements. This combination of practicality and adaptability makes perforated cladding a reliable and sustainable choice for architectural projects in humid, tropical climates.

2. Are there limitations regarding the number and size of perforations?

While ensuring the panel's rigidity and adherence to structural specifications is crucial to ensure that panels do not warp, there are minimal restrictions on the number and size of perforations. We have the flexibility to incorporate large perforations or numerous smaller ones across the panel, depending on the open area percentage that you prefer. For privacy concerns, some architects select a design where the open area percentage is less than 40%, such as in applications for front facades and gates. Importantly, perforations are not confined to round shapes; they can take on any size or form, enhancing the design possibilities.

3. Can perforated claddings be customised?

Perforated claddings are a canvas for customisation - you can dictate the panel size, design, fabrication and bending, and finishing coating, to suit the specific needs of your project. Standard panel size is 1.2m x 2.4m (4FT x 8FT), but custom sizes can be manufactured. Our team will advise on the maximum panel size possible for your project while ensuring panels adhere to structural specifications and do not warp. We have hundreds of perforated designs available, ranging from round to slotted to unique designs - from 3mm hole openings to 15mm hole openings.

For aluminium and steel perforated panels, the finishing can be Powder coating or Fluorocarbon (PVDF) coating.

4. Can we fit perforated cladding on an existing building?

Absolutely, the adaptability of perforated cladding extends to existing structures, making it a viable option for renovations and redevelopment projects. Whether it's a subtle addition or a bold transformation, perforated cladding can be tailored to suit the unique characteristics of existing buildings, offering architects a versatile tool to redefine and revitalise architectural spaces. Many perforated claddings have been used as internal facades and wall dividers in heritage shophouses in the Katong and Joo Chiat areas.

5. How does perforated cladding impact energy efficiency?

Architects are increasingly focused on sustainable design, architects frequently inquire about the role perforated cladding plays in advancing sustainable design. By strategically managing natural light, these facades reduce the reliance on artificial lighting while preventing overheating in interiors. This dual functionality not only enhances the building's eco-friendliness but also aligns with modern architectural trends emphasising sustainable practices.
