SYSTEM, METHOD AND APPARATUS FOR THERMAL ENERGY MANAGEMENT IN A ROOF

摘要

A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.

主权项

1. A roof product, comprising:
an underlayment configured to be attached to a roof between a roof deck and a roof shingle; the underlayment comprising: a thermal heat storage layer having a heat capacity that stores solar heat during a heating cycle, and has a thermal emittance that re-radiates stored heat during a cooling cycle; a vent layer having channels to transfer excess heat through an entire axial length of the roof product from a top edge of the roof product to a bottom edge of the roof product; a flame retardant to suppress fire through the vent layer; the thermal heat storage layer and the vent layer are combined together in a single layer having a first boundary and a second boundary, and each of the thermal heat storage layer and the vent layer extend to both the first boundary and the second boundary; and the thermal heat storage layer, vent layer and flame retardant form a unitary structure comprising the underlayment.
