The grades/strength classes of frost insulation products are listed below: F-200. The short-term compressive strength of F-200 exceeds 200 kPa, i.e. 20,000 kg/m 2 and the long-term compressive strength exceeds 90 kPa, i.e. approx. 9 t/m 2.
NettetCompressive strength is the capacity of a material or structure to withstand loads. This term is often used to refer to compressive properties of rigid materials. For FOAMGLAS® insulation, the compressive strength is determined using a capping procedure described in ASTM C240 Standard Test Methods of Testing Cellular Glass Insulation Block. NettetCharacteristics of a Good Insulating Material: A good insulating material should possess the following characteristics: 1. Large insulating resistance. ADVERTISEMENTS: 2. High dialectic strength. 3. Uniform viscosity—it gives uniform electrical and thermal properties. 4.
