Document Type and Number:
WIPO Patent Application WO/2016/031236
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a heat-shielding roofing underlayment material that has sufficient heat shielding properties, and has satisfactory slip resistance and waterproofness required as properties of roofing underlayment materials, and in addition, has durability such that the roofing underlayment material is durable for long-term construction. [Solution] The heat-shielding roofing underlayment material has: a metal film layer which contains a metal pigment, a binder, and a particulate member, and which is an upper outermost layer in a vertical direction; and at least a reinforcement layer and a waterproof layer which are disposed below the metal film layer. The heat-shielding roofing underlayment material is characterized in that the metal film layer has an average infrared reflectance of 60% or more in the wavelength region of 5-10 μm and an average infrared absorbance of 30% or less in the wavelength region of 5-10 μm.
