WM Vermiculite Insulation has been developed to satisfy the stresses required in the industrial world. Our products are manufactured using expanded silver vermiculite which is lightweight and yet very strong. The controlled pore structure allows for superb thermal sufficiency, minimizing the loss of heat and promoting increased energy effectiveness. This means that our insulation bricks can be used in all sorts of applications including refractory linings as well as backup insulation in furnaces where high-performance insulation is required.
