Metal and wood building materials

Under ideal conditions, building materials such as metal and wood can last indefinitely. However, construction or building defects or lack of maintenance can cause the building materials to degrade under less than ideal conditions. Therefore, it is important to check these building materials for various aspects. 

Metal building products

Metal as a construction product is regulated according to the European Construction Products Regulation CPR and European harmonised specifications or national standards.

Building products made of wood

The certification of wood products guarantees that the product requirements of the building authorities and the fire safety regulations are fulfilled. Therefore, not only an initial test is required, but also continuous monitoring of the manufacturer. This must be carried out by an independent and accredited notified testing body. Kiwa helps you to make the high quality of your timber construction products visible.
