ejotherm® screw-in anchor S1 short

​​​​​​​The all-rounder for thin insulation boards

06.01.2022, Construction Division

If thin facade insulation panels are used, for example, in the renovation of listed buildings or in window soffit areas, there are additional requirements for washer anchors. The under-head geometry in particular plays an important role. Standard ETICS washer anchors quickly reach their limits here.

EJOT has developed the screw-in anchor with plastic screw ejotherm® S1 short especially for the use of particularly thin insulation thicknesses of 20 – 60 mm. It is suitable for all thin insulation materials, such as high-performance, soffit and ceiling insulation boards, and enables flush surface installation in all substrates.

​​​​​​​The ejotherm® S1 short impresses with a short under-head area and a short anchoring depth. The innovative assembly tool ejotherm® S1 short enables an optimal setting position. The integrated bit finding leads to a high level of assembly comfort – even in constrained positions. The screw anchor is approved for all use categories (A-E) and is therefore an absolute all-rounder in its field.
