About Roofing Materials

The roofing material used is Ai-Gi Kogyo / Super Galtect. Super Galtect comes with a 15-year coating warranty and a 25-year perforation warranty from the manufacturer, along with a 10-year construction warranty from our company! Additionally, it is made of SGL steel, which is resistant to rust.

The insulation material is tightly applied from edge to edge of the roofing material, creating a metal sheet that integrates steel and insulation. During installation, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with a high heat-reflective paint, allowing for a cool summer and a warm winter.

Moreover, it has soundproofing properties, which reduce the sound of rain. Being lighter than other roofing materials also minimizes the sway during earthquakes, providing an additional earthquake-resistant feature.

It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s construction achievements show that Ai-Gi Kogyo’s Super Galtect is the most frequently used, gaining significant attention!
