At this time, the lower end portion of the second stage heat insulating layer 7-n ₂ is superimposed and laminated by Δl on the upper end portion of the first stage heat insulating layer 7-n ₁ . Therefore, in order to form the heat insulating layer 7 on the base 5, such construction may be performed from the eaves to the ridge. Also, the board 8 should have a thickness of 9 to 30 mm, taking into account the step t (board thickness) of the heat insulating layer 7.
mm, the outer shape is rectangular, and the width W is approximately 150 mm.
~600mm, and the length L is set to approximately 200~3636mm. This was selected because of its strength, the fact that there are steps with dimensions that give the appearance of a stepped roof, and the general dimensions of exterior materials, such as roofing materials. Furthermore, the board 8 is made of waterproof material, heat insulation material, reinforcing material,
In addition, in order to function as a humidity control material, high-quality wood logs are pulped and further defibrated and refined, and raw materials include water-resistant agents, preservatives, insect repellents, and asphalt. Moreover, the board 8 is made by forming a board from this raw material, and also by coating the surface with asphalt, impregnating asphalt before forming into the board, or using asphalt powder and refined fibers. It consists of one plate, etc., which is mixed, heated and pressurized. In particular, the amount of asphalt impregnation or coating is 10 to 40% considering waterproofness and humidity control properties.
(weight ratio). The reason for specifying the amount of asphalt impregnated as above is that if it is less than 10%, it lacks waterproofness, and if it is more than 40%, the humidity control property, so-called breathability, is significantly reduced. moreover,
The mat 10 fills the void 9 having a triangular vertical section formed between the base 5 and the back surface 8a of the board 8, reinforcing the board (surface contact), strengthening waterproofness and heat insulation,
