Abstract
A roofing system and method of installing a roofing system can include a roof deck with first and second layers applied over the roof deck, and with a membrane applied thereover. The first and second layers can comprise insulation materials, with at least one of the first and second layers including a reinforced insulation material comprising a substrate with a reinforcing sublayer integrated therewith. The reinforcing sublayer can define an upper surface of the reinforced insulation material. The roofing system is configured to resist impacts from hail and other objects without a coverboard.
Claims37
A roofing system, comprising:
- a roof deck;
- a first layer positioned above the roof deck, the first layer comprising a first insulation material;
- a second layer positioned above the first layer, the second layer comprising:
- a substrate comprising a second insulation material;
- and
- a reinforcing sublayer integrated with the substrate defining an upper surface of the second layer opposite the first layer;
- wherein the reinforcing sublayer comprises a fiber reinforced polymer composite material;
- wherein the fiber reinforced polymer composite material comprises a plurality of glass fibers, carbon fibers, natural fibers, or a combination thereof mixed with a resin;
- and
- a membrane positioned above the upper surface of the second layer;
- wherein the roofing system does not include a separate coverboard layer between the second layer and the membrane.

A package comprising:
- a plurality of insulation panels including reinforced insulation panels;
- wherein each of the reinforced insulation panels comprises:
- a substrate;
- and
- a reinforcing sublayer laminated to, attached to, extruded with or molded with the substrate so as to be integrated with the substrate,
- wherein the reinforcing sublayer comprises a fiber reinforced polymer composite material;
