ONLY FROM WECKMAN
WECKMAN side fastening solution allows free thermal expansion of the roofing material and reduces buckling and noise from the roof panel.
WECKMAN ventilation spring ensures adequate roof ventilation in the Weckman ridge structure even in cold weather. Moisture is removed through the ridge without condensing on the underside of the roofing, thus minimizing the risk of damage to structures beneath the roof.
