Perforated facades offer a cost-effective refurbishment option to upgrade the aesthetics of an old building. Panels are typically lighter than other facade options and offer the benefit of solar shading as well as helping reduce the loading on the structure of a building.
From uniform circular perforations, honeycomb patterned latticework and mesh, through to three-dimensional forms, perforated cladding has the ability to add depth, texture, and intrigue to any façade.
Perforated cladding provides a practical purpose too, depending on the size of perforations, the amount of natural light reaching the inside of the building can be managed, making this an option for solar shading. Large perforations allow more natural light to pass through the cladding, but still protect buildings that have large glazed elements from direct sunlight. In doing this they reduce the amount of solar gain, mitigating the need for expensive AC solutions.
Interestingly, specifying perforated cladding over an existing glass wall doesn’t significantly affect the view from inside the building. Our recent project in Paratai Drive, Auckland (using solid 5mm aluminium sheet) is a great example of this.
Solid sheet aluminium is non-combustible and does not burn, making it a solid contender as a Rainscreen option.
Where the finished product is aluminium, we recommend the following surface finishes:
Insite have the expertise to provide engineered detailing to assist your design for engineered structural soundness with multiple ways to manufacturing, including high pressure water-cut, CNC turret punch and plasma cutting options that can undertake cutting of practically any material with high precision. The ultimate selection for creating the perforation depends on a number of factors, i.e the material to be cut, detail, the thickness and quantity.
Up to approx. 50% maximum perforation; let your imagination be the only limiter to the design.
The water cutter is one of the most versatile cutting machines as it can be used for multiple material types, including non-conductive materials such as plastics and glass, as well as all metal types. Because the cutter uses water to create the shape, the temperature is kept very low practically eliminating the high temperatures that can cause deformation of metal, or heat colouring to raw metal.
This machine offers an outstanding ability when it comes to repetition and accuracy when cutting metal sheets and creating standard shapes. We are also able to engineer a bespoke tool for your design if required.
Plasma cutters are regarded as the fastest of the cutting options available in the market for conductive materials, i.e not suitable for materials other than metals. They operate by applying an accelerated jet of hot plasma. Due to the high speed, precision and low cost they are a viable tool for many large scale projects.
We have the ability to cut fine unique structural elements, right up to full sheet bespoke patternation.
