Hess-timber Glued Laminated Timber
GLUED LAMINATED TIMBER
GLUED LAMINATED TIMBER
The Engineered Wood Beam
High-quality glued laminated timber (GLT) is characterized by a high structural capacity, aesthetic aspects and the free shaping possibilities of the timber construction parts.
Glued laminated timber is available in straight, curved and turned variants and thus presents almost unlimited design flexibilities for timber construction.
We develop individual and project-specific product solutions to meet the complex requirements of modern timber construction architecture and regularly explore the limits of what is feasible.
The access to the broad and innovative product portfolio of the entire HASSLACHER Group enables us to use the ideal product solution for every project requirement.

DETAILS
ADVANCED
With the manifold possibilities of our advanced glulam components, we are in a position to realise extraordinarily high-quality, complex and highly resilient as well as combined and hybrid glulam components.
CUSTOM
We have many years of experience in the development of projects with special and extraordinary wood species such as acetylated Pinus Radiata, Oak, Beech, Chestnut, Iroko, Padouk or American Tulipwood. In addition to the use as full cross section, many wood species can also be combined as hybrid components.
