Insulating material retainer fixing a pressure-resistant insulating layer and weldable roof sheet with an inventive device on a base has a curvature and forms snap spring element that can snap over into opposite curvature

摘要

The insulating material retainer has a curvature and forms a snap spring element that can snap over into an opposite curvature. The insulating material retainer (1) forms a thermally triggered snap spring element that snaps over under heating when under tension transverse to its surface. Independent claims are also included for (A) an arrangement for fixing a pressure-resistant insulating layer and weldable roof sheet with an inventive device on a base (B) and a method of fixing a pressure-resistant insulating layer and weldable roof sheet with an inventive device on a base.
