Unique Ultralam LVL™ properties afford to list it among the most prospective materials used for construction
One of the main LVL advantages is its strength characteristics achieved through manufacturing technique. Laminated structure makes LVL strong and durable.
Veneer graded against density is used for LVL production. Best veneer grades are put into the face layers; lower grades – in the middle. Such pattern provides for the stable mechanical properties of LVL. Heavy pressing used for veneers gluing results in densified structure of wood fibers; phenol-formaldehyde resin assures heavy-duty glue line. LVL has homogenous structure with constant physical-mechanical properties.
LVL properties do not change over its lifetime.
LVL maintains dimensional stability regardless of seasonal factors, environmental variations and climate conditions. This material is not subject to deformations caused by temperature and humidity variations; it doesn't crack and has low values of natural shrinkage. LVL moisture absorption is almost equal to zero, i.e. dead load of LVL beam will remain unchanged under humid environment. Dimensional stability assures high accuracy of adjacent elements.
LVL boasts better fire resistance compared to ordinary beams. This is achieved through multiple layers of veneer and less porosity of material. Phenol-formaldehyde resin is neutral to oxidation and doesn't support ignition. High density and absence of cracks prevent from fire propagation and thermal effects inside the material. LVL test results demonstrate the ability of the material to maintain its properties within 30-60 minutes at 300°C.
As opposed to metal and reinforced concrete, LVL has better resistance to corrosive environment. LVL application provides for more space and long-span structures, minimizing the number of beams and trusses. Solid wood is not suitable for such task since its beams are subject to deflection and vibration.
LVL beams characterized by high-strength and unlimited length allow to save on material, fasteners, delivery and installation costs.
