Bertolotto Internal Door – CL V
The CLV collection combines the elegance of a hand-lacquered door with the brightness of a vertical glass insert: a 230 mm strip of 8 mm tempered glass (standard Extra-Clear Frosted, optional Bronze/Grey or with double-sided mirrors) that lightens rooms and enhances clean, modern lines. The door leaf features a "big" hollow core structure with a 50 mm frame in solid finger-jointed wood, a 100% recycled kraft paper honeycomb core, and 5 mm MDF skins (IDRO, CARB, FSC®), edged on 4 sides with IPER4BOARD ABS 10/10. Standard features include 3 concealed hinges and a magnetic lock; TR/L8 frames or, upon request, TKT L9/P85 and TKS L9/P100; low-impact water-based lacquers.
