About Roofing Materials

The roofing material used is Ai-Gi Kogyo / Super Galtect. Super Galtect comes with a 15-year paint warranty and a 25-year hole 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 the steel plate 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 also has soundproofing properties, reducing the sound of rain. Being lighter than other roofing materials, it minimizes the sway during earthquakes, providing earthquake resistance as well.

It excels in finish, durability, insulation, soundproofing, and wind resistance, and Super Galtect from Ai-Gi Kogyo is the most frequently used in our construction achievements and is receiving significant attention!
