BSP has developed new passive system (BSP KWE threaded rod system) with large-scale thermo-modernization of existing facilities in mind. Elements of this system are fixed directly to building structure without the need to remove existing layers of thermal insulation. Installation of new facade is therefore much faster and easier. BSP KWE can be used on new buildings as well, both as fixing method of facade as well as suspended ceilings.

Moreover thanks to use of threaded rods coefficient of heat transfer is very low. Coefficient of linear heat transfer caused by the insertion of the profile into the thermal insulation layer does not occur at all.

BSP KWE uses the same elements independently of the outreach, which is almost unlimited. The coaxial effect of the pressure and suction of wind forces (loads) to the anchorage positively effects strength/resistance of the entire system.
