External Thermal Insulation (ETICS)

External thermal insulation (ETICS) is the most common way to upgrade existing buildings. It wraps the building in a continuous shell that removes thermal bridges and moves the dew point outside the wall: the envelope stays warmer in winter and cooler in summer, protected from the thermal shocks that crack renders. It is the basis of almost every energy-efficiency retrofit.

1. 01

   Substrate preparation

   Cleaning, levelling and flatness check of the wall. Removal of loose parts and primer application.

2. 02

   Bonding the panels

   Adhesive application and laying of insulation panels from the bottom up, with staggered joints.

3. 03

   Mechanical fixing

   Mechanical fixing with expansion anchors after the adhesive has cured (typically 24-48h).

4. 04

   Reinforced base coat

   Application of the base coat with embedded glass-fibre mesh, in two layers.

5. 05

   Finish coat

   Application of the breathable, protective final coat (mineral or silicate render).
