TimberStrand® LSL Floor Joists

For floor performance and code requirements

TimberStrand® LSL is an ideal solution, providing an alternative to solid sawn floor joists, especially where longer lengths and greater stability are required. Floors work harder these days, supporting heavy kitchen islands and great rooms. Rely on TimberStrand LSL joists to deliver the loads you require.  

TimberStrand LSL floor joists also deliver 2 x 10 fire equivalent performance required by 2012 and 2015 IBC.
