primolam® – Cross laminated beam system for walls & ceilings
The primolam cross laminated beam system is the logical further development of the successful Weinberger product Bilam forte. It combines the relevant advantages of both cross laminated boards as well as brettstapel systems and laminated beams in an innovative wall and ceiling system.
primolam à la Weinberger
- Smaller cross-sections due to a higher share of lengthwise timber
- Combines the advantages of cross laminated boards glued along the narrow side and those not glued along the narrow side
- Extremely high dimensional stability thanks to cross-glued timber
- Can be used even for thin-walled, multi-storey timber structures
- For panel constructions in the popular log cabin look for walls and ceilings
- Non-settling
- Can be used for load-bearing walls both vertically and horizontally

Assembly made easy
The primolam cross laminated beam system doesn’t just look good, it is also very easy, quick and cheap to assemble, no matter whether it is built with panels or boards.
The cross laminated beam elements can be finished on site or pre-assembled in the carpenter’s workshop to wall size.
