Itlas has a system of certification and attestations to guarantee technical and environmental characteristics, and reduced home pollution. Only products made entirely in Italy can be so complete. Itlas products are recognisable because the bottom part is always finished with birch plywood for Legni del Doge and birch plywood, plus a layer of solid fir wood for Tavole del Piave and Assi del Cansiglio. The layers are glued together with Class D3 vinyl adhesive.
