Webertherm ETICS System

The Webertherm ETICS System is an External Thermal Insulation Composite System (ETICS) designed for façade applications, compliant with EN 15804+A2:2019 and the Construction Products Regulation (CPR). It holds European Technical Assessment ETA 14/0365, based on EAD 040083-00-0404 for ETICS kits using EPS insulation and continuous coating.

It is based on webertherm placa EPS, a stabilized expanded polystyrene insulation board with excellent thermal performance (thermal conductivity, λ = 0,037 W/m·K). The system is designed to improve the thermal efficiency of the building envelope, while providing a solid and durable base to be coated with any of the following proposals: thin layer mineral (webercal ESTUCO), and organic (webertene range).

• Supply and application of webertherm placa EPS insulation boards, installed horizontally in successive rows with staggered joints. Boards are adhered using webertherm base adhesive mortar, applied either by perimeter bead and central dabs or by full surface troweling, ensuring a minimum adhesion surface of 40%. Use as reference 100 mm.

• Mechanical fixing of insulation boards using webertherm espiga anchors of steel and plastic, with a minimum of 6 fixings/m², reinforced in wind-exposed areas. Anchor type must be selected according to substrate characteristics.

• Surface reinforcement with webertherm malla 160, an alkali-resistant fiberglass mesh with a mesh opening of 3,5 x 3,8 mm, weight 160 g/m², thickness 0,52 mm, and elongation resistance of 3,8 / 3,8, embedded between two layers of webertherm base mortar (2–3 mm per layer).
