Perimeter Fix Insulation Support Fixings for Concrete Substrate


The EJOT DH range is a two-piece rainscreen insulation anchor manufactured of polyethylene for insulation thickness of 60 to 300mm and reducing packaging volume up to 80%. The DH Shaft anchor is knocked in the push-through installation using a hammer, the shaft has a setting depth limit, this is an exact mounting position of 30mm embedment depth for both masonry and concrete. The high quality plastic ensures a safe installation process, even for large thicknesses of insulation and prevents the buckling of the shank when driven into the substrate. Rotary hole drilling required in aerated and perforated brick.

DH 90 Disc

The DH disk prevents unwanted quilting effects when compared to conventional insulation supports which are sometimes driven deeply into the substrate as as they have no depth limit, and at butt joints of insulation can even result in gaping of the insulation. For the installation of two-ply insulation additional stress plates are required, the practicability depends on the respective insulation properties and needs to be tested on site.
