Good quality wood is just the beginning of manufacturing of good quality product. Therefore, Drewexim has always been supervising the production process and thoroughly testing all the most important parameters of the scantlings. Only by using good quality components it is possible to manufacture good quality windows and doors. Only good quality windows can be covered with full guarantee. Only good quality windows can fully satisfy the customer.
Basic stages of testing:
1. Inspection of the tightness of finger jointing.
2. Inspection of the gluing.
3. Inspection of the durability of the gluing after being exposed to water.
4. Gluing is perfect only if the scantling splits along the solid wood and not along the glue line.
5. Inspection of the quality of gluing in the the finger jointing.
