Values
made to last
We have always had a very precise philosophy that dictates we keep our standards of product quality and customer service at the level of excellence our customers deserve.
With over thirty years of experience in the doors and windows sector, Dieffelegno specialises in creations built around MORTISE AND TENON joints that are the direct result of centuries of working with wood. These joints give our doors and windows superb mechanical resistance and prevent structural failure.
The use of new technologies has also enabled us to obtain Energy Performance Certification for out mortise and tenon joints in full compliance with very rigid protocols and standards as a result of which our products provide extremely high performance characteristics.
