We provide testing services of thermal insulation products and materials for product development, market approval (CE-marking and Keymark) and quality assurance of production.
Our testing services cover mineral wool (MW), polystyrene (EPS), extruded polystyrene (XPS), polyurethane (PUR) and different kinds of wood fibre and cellular rubber insulation products according to their specific product standards. We also test various other insulation and building materials according to their specific product standards.
Most of the testing methods of VTT Expert Services Ltd are accredited by national accreditation services (FINAS T001). Additionally VTT Expert Services Ltd is a notified body for a number of product standards.
We are happy to serve you in all your needs concerning testing, CE-marking and product approvals of thermal insulation materials and products.
