1 Breathability
Our Pre-roofing material does not fluctuate in temperature as the spaces between the roofing board and roofing material has excellent ventilation, there is no stuffiness with the roofing boards (composite panel etc.) and roofing materials being long lasting and almost permanent. The product is compliant with the Japanese climate that is high in moisture.
2 Prevention of dew condensation
The Pre-roofing material makes use of a special method implementing a cylindrical shaped rod with a height of 1.5mm and width of 8mm, rain water blown under the tiles soon flows in the direction of the wind as the rod has raised the paved tiles. As the rod has been hammered into the paved tiles water never leaks through the hole created by the rod.
3 Water resistance
The Pre-roofing material makes use of a special method implementing a cylindrical shaped rod with a height of 1.5mm and width of 8mm, rain water blown under the tiles soon flows in the direction of the wind as the rod has raised paved tiles. As the rod has been hammered into the paved tiles water never leaks through the hole created by the rod.
4 Stability
A special compound resin is used. The two surfaces fit tightly together, construction of the roof can be performed safely as the surface has a rough finish that prevents slipping when working on an inclined roof. As transparent wood-free paper that does not shrink easily is used markings can be easily performed and can be compared with products from other companies.
5 Applicability
Concerning our Pre-roofing material, the applicability of the paved tiles is superior to that of other companies' products and as a result the stability of the tiles has increased greatly too.
6 Operation comfort
It is non-sticky in summer, does not have a poor odor and is possible to operate safely during construction.
