Wooden Fiber Board Import for Forestry Products

I am insulation the attic (under the roof) and the overall thermal resistance should be above 7: - 200 m2 (Square meters) of Steico flex wood fber boards / panels 36 or another equivalent brand - Thickness 100 mm - Thermal resistance R= 2.75 - 200 m2 (Square meters) of Steico flex wood fiber boards/panels 36 or another equivalent brand- Thickness 160 mm - Thermal resistance R= 4.40 In the meantime I have some questions: - Can you also let me know if you are supplying OSB panel boards of 15 or 22 mm? I would need 100 square meters for the floor?
