Since 2004 our company has started here in Italy the production of 3-layer wood elements for window and door building. We have been gaining a lot of experience during these years and we can now offer them in several wood species, such as: Okoumé, Ozigo, Slavonjan Oak, Tulipier and Lime. All elements are glued employing a vinylic glue pvac – d4 – en 205 only.
