2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS

2.2.7 Renovation applications

In renovation, old floors can be reinforced with LVL without

increasing the loading of old supporting structures significant-

ly. LVL-P joists can be fixed to the sides of old joists. This is

practical because LVL beams are light to lift and fit into the cav-

ities between the joists. Another alternative is to install LVL-C

panels on top of old joists. This method provides a rigid struc-

ture and can be used to improve the overall bracing of a build-

ing. Structural gluing in on-site conditions is demanding, but

gluing can be used to reduce deflections. Another connection

method is inclined screwing, which gives good stiffness to the

connections between old and new components.
