Reasons for anchoring an ETICS

Why should I use anchors at all?

Because that is the safe way

EJOT anchors offer the highest loadcarrying capacity on old facades

ETICS systems are predominantly used for the energy renovation of older buildings.

The risks from old plaster are significant:

• exposed to weather and emissions over decades • soot, dirt and old paint films reduce the loadcarrying capacity of the adhesive • individual components are incompatible with the adhesive • structural-physical influences may lead to changes in the load-carrying capacity, even after many years • facade cleaning is extensive and expensive • waste water containing harmful substances must be collected and disposed of professionally • the old plaster is soaked through by a thorough cleaning

Residues from formwork oil on concrete may even cause a problem in the area of new buildings when bonding the new ETICS systems.

The benefits with the additional mechanical fastening:

• no special pre-treatment of the facade • loose plaster points, efflorescence and peeling coats of paint only have to be roughly removed • possible points of failure only have to be rendered-over

Briefly: EJOT anchors ensure for safe retention. EJOT anchors offer high structural integrity

The dead weight of an ETICS is transferred only by bonded ETICS systems only via adhesion forces between the adhesive and insulating material as well as adhesive and old facade. Thus, the adhesive used is te only joint between the wall and insulating material.

Thanks to the stable anchor washer and the high load bearing capacity in the substrate, the ejotherm washer anchors give your facade a safe hold. Due to the additional pressure generated, the friction between the surface of the facade and the ETICS system is permanently ensured.

The benefits of ETICS anchors with steel screw or steel nail:

• high stability of the complete system • permanent friction locking between the adhesive and substrate • high safety under wind loads • higher safety margin in case of fire

EJOT anchors ensure for higher safety compared with hygrothermal influences

Temperature fluctuations and material-related shrinkage leads to tension that has a negative effect to the rigid adhesive connection. This can lead to a failure in the bonding surface and the related loss of adhesion to the substrate.

With the sole bonding of the ETICS system, there is also the • latent danger of bulging • cupping of the insulation boards as a result of missing possibilities for expansion

Cold outside Warm outside

Advantages of the additional anchoring in the area of the panel joints and the middle of the panel:

• reduction of the bulging of insulation boards • reduction of the cupping of insulation boards • risk minimizing of plaster cracks

EJOT anchors offer high safety against wind loads

Wind loads act vertically to the surface of the facade. They ensure for a vertical tensile load to the adhesive surfaces. Particular importance is placed on the transitions between the wall / adhesive (new buildings) or old plaster / adhesive (renovations) and adhesive / insulating material.

Higher wind loads typically occur

• on higher buildings • on the edges of buildings • on free-standing buildings • with exposed locations on coastal regions as well as on islands
