Ultralam advantages

Unique LVL Ultralamโ„ข properties afford to list it among the most prospective materials used for construction.
The application of LVL Ultralamโ„ข covers a wide range of construction and not construction areas.

ฬŒโœ“ Environmentally friendly engineered wood material with unique performance.

โ€‹

โœ“ Durability and long lasting appeal of Ultralamโ„ข -based structures.

โ€‹

โœ“ Unchangeable performance over the entire service life.

โ€‹

โœ“ Homogenous material with unchangeable mechanical properties lengthwise.

โ€‹

โœ“ Consistent geometry and physical properties regardless of seasonal factors, environmental variations and climatic conditions.

โœ“ High accuracy of adjacent elements.

โ€‹

โœ“ High bearing capacity.

โ€‹

โœ“ Resistance to corrosive agents.

โ€‹

โœ“ Optimal performance/weight ratio.

โ€‹

โœ“ High bio and fire resistance.

โ€‹

โœ“ High thermal and sound insulating properties.

โ€‹

โœ“ Material is easy to process with any cutting instruments.

โ€‹

โœ“ Material is not subject to deformations caused by humidity variations and has low values of natural shrinkage.

โ€‹

โœ“ There are almost no service costs related to LVL usage.

โ€‹

โœ“ Convenient, easy and fast installation of LVL products.

โ€‹

โœ“ With an adequate strength reserve, reinforced foundations and bearing structures are not required.

โ€‹

โœ“ Price of Ultralamโ„ข products do not depend on their length and cross sections.

โ€‹

โœ“ Easy mechanical processing and preservative treatment.

โ€‹

โœ“ Besides its high physical and mechanical properties, laminated veneer lumber fully retains the appearance

of natural wood which allows to use LVL-based products and structures in interior applications without

additional finishing.
