Architraves are used to cover the gaps between the door frame and the door itself, and can also be used as mouldings. SIA Mars manufactures and sells pine wood architraves of various sizes. The branchless, glued in length, architrave N4 is made of high-quality pine saw logs. Architraves are industrially dried and contain 12% (+/- 2%) moisture.
