1. Energy saving

The outer panel is sandwiched with a 50-thick extruded board in the middle of the double-sided concrete, and its thermal insulation performance is better than that of the external wall of the traditional building, and also solves the phenomenon of the external wall interior falling off due to the external thermal insulation of the traditional building.

2. Environmental protection

After the factory production of the assembled inner wall panel, the construction waste on the construction site is greatly reduced and it is more environmentally friendly.

3. Save templates

Because the composite plate is the bottom mold of the slab, and the outer plate is the unilateral template of the shear wall, a lot of formwork is saved.

4. Shorten the construction period

Due to the large number of prefabricated inner wall panels and prefabricated plywood produced in the factory, the on-site construction intensity is greatly reduced, and the process of construction and painting mortar is also eliminated, and the overall construction period is greatly shortened.
