The external wall insulation formwork is a newly developed product of our company. It is a structural board that integrates multiple functions including formwork and insulation. In the structure of modern residential buildings, it replaces the wooden formwork used in the traditional cast-in-place concrete process. Moreover, it inherently has insulation functionality, which aligns with the modern environmental protection concept of people caring for forests and nature. Therefore, it is a green, energy-saving and environmentally friendly material.
