Which is good for insulation and sound insulation of glass wool and expanded vermiculite?
The development of thermal insulation vermiculite is very slow in China. Heat preservation technology is divided into two categories: internal heat preservation and external thermal insulation.
The insulation is currently promoting the building wall insulation technology, insulation package on the inner side of the main structure of the main structure to protect and extend the life of the building, effectively reduce the thermal bridge building structure, increase the effective space, improve the living comfort.
At the same time, with internal thermal expansion vermiculite material processing of vermiculite stone slab, with three hours of fire protection, deformation, and has sound insulation, insulation and other functions.
