EROOF（イールーフ） List of Products and Services

"Eternit" is a translucent and light-blocking screen construction method that densely realizes decorative details of modern architecture through a flexible custom-made system. It can be made up to 9500mm in length, with curved processing, custom bends, and custom punching available. Additionally, if you provide CAD data under specified conditions, custom products can be manufactured and constructed based on standard pricing. [Features] ■ "I want to convey the texture of light and wind within." A facade that creates a private space along the roadside and boundary walls visible through the window. ■ "Creating a facade as a surface." A boltless construction method that enables the designs sought by architects. *For more details, please download the PDF or feel free to contact us.

• Blackout screen
• Special Construction Method

Overwhelming construction speed and design compared to conventional corrugated roofs. This is a revolutionary standing seam roofing method that allows for the Galvalume roof to be installed simply by rotating and snapping it into place. It can be easily constructed even by beginners, significantly reducing the construction costs and time for temporary housing.

• Others/Roofing materials (shingles, cement, steel sheets, aluminum)
• Roof and gutter construction

SOLARIS PROTEA is the world's first rotating fitting-type solar roof system that integrates solar cells. Through the collaboration of highly regarded amorphous solar cell laminates, such as those from environmentally advanced countries like Germany, and the integrated fitting standing seam roofing: Harper's Strong Roof SF, it has become possible to achieve lightweight solar architecture along with speedy and rational design and construction.

• Building renovation system
• Other interior and exterior systems and units
• Power generation equipment

The Promna Roof Excel, chosen by construction professionals, provides maintenance-free roof balconies for wooden structures. Balconies in wooden buildings, which cannot avoid deformation and swaying, generally require maintenance because the waterproof layer can break due to substrate deformation and external forces. However, the Promna Roof metal waterproofing method incorporates a multi-layer waterproofing device with excellent toughness (ductility), achieving zero leaks in hundreds of thousands of installations. It has gained immense trust from construction experts. The safe and comfortable wooden balcony space, free from concerns about waterproof layer breakage, sick house syndrome, and environmental pollution, is created by Promna Roof.

• Balcony/Sunroom Unit

The Wet Jet green roofing method is a thin-layer greening system that can create a rich vegetative environment with minimal irrigation equipment and maintenance. While green roofs and green walls are often discussed with an environmentally friendly image, they actually rely on greening technologies that have a significant environmental impact. The Wet Jet has established a true ecological greening system by replicating the terraced rice farming techniques seen in the mountainous regions of Southeast Asia using metal roofing technology. Even with a small amount of irrigation, water gradually spreads downward like in a terraced field, ensuring an adequate soil moisture level across the entire planting area. Furthermore, despite being a thin-layer greening method with a low design load, it allows for the cultivation of various plants from low slopes to vertical wall surfaces.

• Wall and rooftop greenery

This is a groundbreaking solar power generation system roofing method that can be installed on curved roofs. Traditional solar power systems include mounted systems that place solar modules on the roof and integrated systems that combine the roof material with the solar cells, but both are limited to flat surfaces for installation. Our Silver Leaf VFP utilizes amorphous laminate solar cells that can be freely bent. By incorporating it into a special smooth metal roofing system that allows for curved installation, it enables innovative architectural designs that overturn the conventional image of solar power generation.
