Bad Staffelstein / Germany, June 10th, 2013 – IBC SOLAR AG, a global leader in photovoltaic systems, presents the IBC ASD – a wafer-head screw for mounting solar power systems on roofs with above-rafter insulation. Visitors at the trade fair can see this product innovation for the first time at Intersolar 2013, the world’s largest specialist trade fair for the solar sector, from June 19th – 21th in Munich at the IBC SOLAR stand (Hall B6, Stand 310).
The IBC ASD is designed for installing solar modules on wooden structures with insulation. With its innovative under head thread, the special screw prevents the pressure on the insulation material becoming too high due to the photovoltaic system. If further thrust-absorbing loads occur, they can be redirected using partial-thread screws (screwed fastening brackets at roof pitch 60°).
With the under head thread and the corresponding distance screw connection, the pressure strain is transferred directly to the rafters with both low-strength and pressure-resistant insulation. The under head thread also fixes the counter batten in place. The high-precision screw tip of the IBC ASD additionally prevents the counter battens from splitting during assembly. “The screw, made from stainless steel, guarantees lasting reliability and also enables our specialist partners to install solar systems quickly and easily – and completely without drilling,” explains Tobias Zipf, Product Manager for mounting systems at IBC SOLAR AG.
The IBC ASD can be used for all conventional insulation material without pressure resistance requirements and has building authority approval in accordance with Z-9.1-652 and ETA-12/0132.
