We prefer to install loose lintels in the veneer whenever it works – even if it means using composite steel sections for longer lengths.  Typically, loose lintels can be used up to approximately 14’-0” spans, depending on project specific conditions. When veneer lintels are fastened to the back-up wall, they create differential movement in the veneer due to a portion of the veneer bearing on the fixed lintel, and adjacent veneer bearing on a different condition like a foundation. These differential bearing conditions can create cracks in the veneer if vertical movement joints are not strategically placed. Loose lintels provide designers more flexibility for the location of vertical movement joints aligned with opening jambs or even between openings.
