5.1. Introduction Rendered thermally insulated faรงade, also known as ETICS (External Thermal Insulation Composite System) faรงade, is a widely used faรงade system. The system usually includes an inner strong brick layer, a rigid sheet of insulation on the outside, appropriately anchored to the support, and a protection with a rendering reinforced with glass fiber. Insulation Most insulation materials can be used here as thermal insulation, but the adequacy of the entire system must be verified. Extruded polystyrene insulation (6 to 8 cm. thick EPS of 20 kg/m3) is the most usual solution.

The thermal performance of ETICS is ideal to avoid condensations.

Resistance Structural performance is assigned to the inner brick later, while the outer rendering shell deals with external physical attacks. A socket of stronger material should be placed in the base to prevent external aggressions. Waterproofing The outer rendering shell must act as a self sufficient waterproofing element. The rendering will act as an air barrier; the insulation, which must be watertight, as a vapour barrier.
