Thermal Bridging in Rainscreen Cladding
A simple rainscreen cladding support system typically consists of “helping hand” brackets. These are the backbone of any rainscreen cladding system and are fixed to the substrate at set vertical and horizontal separations.
A layer of insulation is then fixed to the substrate, and where the brackets are placed, they penetrate directly through the insulation, forming what is called a “Point Thermal Bridge”. Aluminuim “L” and “T” profiles are inserted into the brackets, lined, levelled, and fixed. A ventilated layer behind the external façade material ensures the risk of condensation is minimised as well as dissipating solar gain in the building.
