Rainscreen Façades
Rainscreen facades involve the attachment of an outer skin of rear-ventilated cladding to a new or existing building underlying structure by means of a supporting grid, which maintains a ventilated and drained cavity between the façade and the structure. The outer layer breathes like a skin while the inner layer reduces energy losses. The structural frame of the building is kept absolutely dry, as water never reaches it or the thermal insulation. Evaporation and drainage in the cavity removes water that penetrates between panel joints. Water droplets are not driven through the panel joints or openings because the rainscreen principle means that wind pressure acting on the outer face of the panel is equalized in the cavity. Therefore, there is no significant pressure differential to drive the rain through joints.
Façade panels can be supplied in a variety of materials - Aluminium Composite Material and Metal Composite Materials consist of two thin skins of aluminium or other metals continuously bonded under tension to either side of a thermoplastic or mineral core. Panels can also be supplied in Powder Coated Aluminium in a large variety of colours.
These panels are available in a large variety of colours and finishes and metals available include Stainless steel, Titanium, Zinc, Copper, Anodised Aluminium etc.
