The Ventilated Rainscreen

For a ventilated rainscreen, the cladding will not be applied directly onto the masonry, but mounted onto a substructure. Thus, insulation (moisture, thermal, sound and fire protecions) and weather protection are constructionally seperated. This method creates a ventilation space between the components, which regulates the moisture balance within the building structure.

The ventilated rainscreen is versatile

With a ventilated rainscreen façade, you emphasise the individual character of a building. Every conceivable combination is possible!

The ventilated rainscreen has a long life

The ventilated rainscreen uses materials that are lightfast, frost-resistant and durable. This increases the service life compared to other façades.

The ventilated rainscreen is safe

The ventilated rainscreen is successful because it allows design diversity and offers safety at the same time.

The undercut system

Your search has an end. With KEIL, you have a complete undercut system, approved by building authorities, technically mature, proven a million times over.

With our system, we ensure a concealed fastening free of expansion force. From small to large, light to heavy: all common panel materials from 6 mm thickness receive an undercut with a precise and consistently symmetrical shape.

You drill cylindrically and then undercut conically in one operation with only one tool. For installation, you insert the KEIL undercut anchor into the drilled hole and set it in an interlocking manner by means of a screw. The path-controlled positioning of the anchor is carried out with the coordinated KEIL system: anchor, bracket and KEIL ratchet screw with integrated screw lock.


Drilling and undercutting in one. Drilling time in ceramics takes less than 10 seconds.


Only two parts are required for secure fastening: anchor and screw.


Our system monitors itself: A KEIL undercut anchor can only be installed in a correct drill hole.
