Title:
ROOF UNDERLAYER PANEL AND ROOF UNDERLAYER STRUCTURE
Document Type and Number:
Japanese Patent JP3967988
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a roof underlayer panel capable of forming a roof having high heat insulating performance with high workability at a low cost.
SOLUTION: The roof underlayer panel is mounted on a roof structural material 1 such as a purlin or the like as a sheathing roof board 2. A gap between the metal-made front plate and the back plate is filled with a thermal insulating material. The roof underlayer with high insulation efficiency can be formed by using the roof underlayer panel A having the thermal insulating material. The roof underlayer panel A with high strength such as bending strength or the like is formed in a lightweight design to have no use to provide the roof structural material 1 such as a purlin, a rafter or the like at a narrow pitch. There is no need to use a large number of roof underlayer panels A by forming the roof underlayer panel A having an area larger than that of a wooden roof board per piece.
