Mechanical tests

Test methods

Thermal insulation products must have certain mechanical properties according to the use to be made of the product. Consequently, the following mechanical properties can be determined.

  • Shear behaviour for insulating products that are part of External Thermal Insulation Composite Systems (ETICS) where the product is subjected to tangential forces.
  • Compression and compression creep for products subjected to loads (floors and roofs).
  • Tensile strength perpendicular to faces when the product is subject to adherences stresses and when the intrinsic weight or suction caused by wind subjects the product to tensile forces.
  • Bending strength  in order to guarantee good cohesion of the insulation product (EPS) when handling the product.
  • Parallel strength parallel to faces to guarantee the physical integrity of the panels and to verify the stress resistance in use.
  • Compressibility when the product guarantees a certain degree of elasticity, e.g. in stress applications such as floating flooring.
  • Point load resistance  when the product is subjected to localised stresses.
  • Resistance to freeze / thaw cycles in products that are subjected to the effects of freezing. After thermal treatment the variation of the resistance to compression is assessed.

Thermal insulation materials to test:

  • Expanded polystyrene
  • Extruded polystyrene
  • Mineral wool
