ETICS weber.therm circle

Name: ETICS weber.therm circle
Brand: Weber

The ETICS weber.therm circle is an external thermal insulation composite system with mineral wool insulation boards and mineral renders according to EN 998-1.

weber.therm circle is the first external thermal insulation composite system, which can be dismantled and recycled by type of component. Once it has reached the end of its service life, again new high-quality components are obtained from the dismantled components.

Substrate

The ETICS weber.therm circle can be used on masonries or concrete.

Thermal insulation

For thermal insulation within this ETICS the mineral wool insulation boards weber.therm MW 040 Facade circle are used.

Dowels

The insulation boards are fastened to the walls only mechanically with screw dowels without any bonding mortar. 10 dowels weber.therm SRD-5 are necessary per m².

Separation mesh

The woven mesh weber.therm 310 is laid as separation fabric within the reinforcing mortar close to the insulation board. During dismantling, it stabilizes the render and ensures a clean separation of the render layer from the insulating material.

Base coat render

A solid base coat render is applied in a thickness of 8 - 12 mm directly on the dowelled insulation board. It is recommended to use the solid mineral reinforcing base coat render weber.therm armadura.

Reinforcement layer

The separation layer is followed by a reinforcement layer (lightweight mortar + mesh weber.therm 310). To do this, the lightweight reinforcing mortar weber.therm 302 is applied in a thickness of 5 - 8 mm.

Woven mesh

weber.therm 310 is embedded a second time in the reinforcing mortar.

Overlay render (top coat)

The top coat render is the third render layer. The solid three-layer render system can thus achieve a total thickness of over 25 mm.

If necessary, the primer weber.prim 403 can be used at first.

For the overlay render there is a choice between thick-layer mineral scratch renders and thin-layer mineral scratch renders. In general, the use of mineral topcoat renders makes easy the recycling of the whole render shell by type of component.
