Under the brand name MM blockdeck, Mayr-Melnhof Holz offers profiled glulam cross-sections for the construction of log cabin walls, ceilings, and roofs. Made of high quality, strength-graded spruce lamellas, these glulam profiles can be used for both modern and traditional wooden homes where the visual and textural quality of spruce timber creates cosy and individual living spaces.

MM blockdeck glulam floor and wall beams, like all structural timber products from Mayr-Melnhof Holz, are PEFC-certified. As a natural, regrowing building material that stores CO2, the use of MM blockdeck makes an important contribution to active climate protection.
