PFEIFER VS®-ISI-System - the overall solution even in case of fire

Since 29.09.2021 the new approval for our VS®-ISI-System is valid.

This makes it the only rail system for connecting precast concrete elements that has proven design values for tension, shear force parallel and shear force perpendicular to the joint for fire resistance class REI90-M.

PFEIFER is leading in innovation and technology.

Our goal is to continuously qualify and improve the products for our customers in order to create added value as well as further application possibilities (e.g. lift shafts and staircases). 
Of course, due to different, qualified mortar suppliers and types, flexibility is also provided in case of fire.
