It is open 6:00 am - 9:00 pm today (Monday). This store principally serves people from the locales of Menominee, Porterfield and Peshtigo. We do not want to add rafter ties because the vertical walls are only 7' tall and we need the headroom. You will find Menards situated at a convenient location at 2080 Old Peshtigo Road, within the south-west region of Marinette ( not far from Pine Tree Mall ). My question is, what size LVL beam do we need? The supplier near me offers microlam LVL 1 3/4" thick beams in 14", 18" tall, and other heights, in any length, that are supposed to be sandwiched to make any width like 3.5" or 5.25". We are not looking to remove anything existing, just slide in a supplemental beam as described here: The video shows roof trusses being cut, but we have no trusses - it just describes the method of lifting we'd like to use. The walls are concrete block except for the triangular gable ends which are framed. We would like to drywall the underside of the "cathedral" type ceiling. The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (glulam). It's got 2x8 rafters, 4/12 pitch, and just a 2x8 ridge board with no rafter ties and just a few collar ties. With LVL now being offered with pressure treatment, it is approved for outdoor decks. Laminated veneered lumber provides uniform widths and strength, as well as the elimination of shrinkage and twisting typically found in traditionally milled, forest-grown wood lumber. I am seeking to add a supplemental structural ridge beam under a ridge board in an old garage, which has some roof sagging (3-4"). The beauty of LVL is it is built to engineered specifications in a factory.
