Mayr-Melnhof Holz MM crosslam is a solid cross-laminated timber panel that can be used for structural and partitioning purposes alike. Three to nine layers of selected softwood lamellas are permanently cross-laminated. This structure produces lightweight yet strong, slim, and dimensionally stable building components with excellent structural and physical properties. Using our modern CNC machining stations we can  create fully finished panels readied for installation and assembly on site. This high degree of prefabrication and the wide variety of panel formats allows for fast, low-dust installation at the construction site. 

MM crosslam, like all Mayr-Melnhof Holz structural timber products, is PEFC-certified. As a natural, regrowing building material that stores CO2, the use of MM crosslam cross-laminated timber makes an important contribution to active climate protection.
