Abstract
A hook and loop system for attaching a roofing membrane into the top of a building insulation board including a roofing membrane with a fleece backing having a release sheet on the fleece backing. The release sheet is manually removed in the field to attach the fleece backing directly onto a layer of hooks that have been pre-attached onto the top of the insulation board. The release layer may be somewhat sticky, yet not adhere too tightly to the fleece layer such that its removal does not damage the fleece backing. The release layer may also be pre-rolled together with the fleece backed roofing membrane and shipped together as a unit into the field.

A hook and fleece roofing system, comprising:
- (a) a roof membrane assembly, comprising:
- a roofing membrane,
- a fleece layer attached to the underside of the roofing membrane, and
- a sticky release film adhesively attached to the underside of the fleece layer, the sticky release film having separate first and second portions positioned side by side;
- and
- (b) an insulation assembly, comprising:
- an insulation board, and
- a hook layer attached directly onto the top side of the insulation board such that the hook layer directly touches and fully covers a top surface of the insulation board;
- and
- wherein the first portion of the sticky release film is removable such that the fleece layer is attached to the hook layer thereby anchoring the position of the roof membrane assembly onto the insulation assembly prior to removal of the second portion of the release layer, and
- wherein the sticky release film is adhered to the fleece layer such that the sticky release film can be manually pulled off of the fleece layer in the field without damaging the fleece layer, and
- wherein the sticky release film has a peel adhesion in the range of 0.02 to 0.05 lbf/in.
