Benefits of Prolam LVL 15
Prolam LVL 15 has a number of advantages over other solid woodbased
The Prolam LVL 15 strength is optimised by grading and selecting veneer for different parts of the LVL cross section and making a very high strength to weight ratio product. Higher strength can mean a smaller section size is required.
Structural properties of LVL are very uniform because the randomised layers of thin veneers are pre-graded for stiffness (coefficient of variation for modulus of elasticity less than 5%).
LVL members have high strength because of the low variability and randomised wood properties in thin layers.
Prolam LVL 15 (wood in general) has a definite advantage over steel members when exposed to corrosive environments. Timber and wood products are able to withstand mild acid conditions and are more resistant to degradation.
