With the diversification of buildings, the demand for high-quality roofing materials with high design value has been increasing. Our company has been involved in the import and installation of natural slate and imported tiles for over 20 years. In particular, regarding natural slate, we propose construction methods that combine design appeal and the functionality of external insulation to meet the needs of the times. We are also committed to the dissemination of natural slate roofs and the preservation of natural slate roofing construction techniques. Furthermore, the method of using the dedicated foam polyurethane "TILE BOND" for adhesion in roofing can be safely used even in areas with strong winds.
