Glulam structures

Rubner Holzbau Solutions Glulam structures

Glued laminated timber, or glulam, is the beating heart of timber engineering. Several layers of spruce wood are glued together in the direction of the grain and processed into customised glulam elements. Our glued laminated timber offers excellent statics qualities. It is light-weight and retains its shape.

From simple load-bearing systems to major timber-frame structures and complete wood structure solutions: we offer the full range from CAD planning to production, delivery, and assembly. Alternatively, we manufacture glulam kits based on your planning documents.

Roof support structures including rooftop configurations

Cost-efficient commercial buildings with a special touch

Native wood types from ecologically managed forests Our group runs its own saw mill, thus making sure that we are present every step of the value chain: from the raw material all the way to the completion of the project.

Our glulam structures, façade profiles, and roof and wall elements absorb carbon dioxide from the atmosphere and help to protect our environment and our climate, thus preserving the world we live in.

Wooden elements have a positive impact on the overall atmosphere in the room. They regulate humidity and surface temperature and have a calming effect.

More than 50 m wide? Trusses of more than 4 m? Our glulam structures are manufactured to order with an efficient use of material in mind and offer top load-bearing capacities.

Parallel chords, ridged roof trusses, fishbelly, bowstring truss, timber frames, and single-pitch trusses: glulam support systems are prime examples of the unique character of timber engineering.

Your construction elements are accurately measured, produced to measure down to the very millimetre, equipped for assembly, delivered reliably and on time, and assembled on site.

Our Ober-Grafendorf facility is a state-of-the-art production facility for special-purpose glulam components and perfectly reconciles industry and individuality. Our two production facilities make it possible to deliver all across Europe.

Using glulam allows for large-range constructions without thermal bridges, offers excellent resistance in chemically aggressive environments, and offers a number of other, lesser known benefits: The material offers a naturally high resistance to fire. The charred layer on the outside of the material caused by fire slows down or even prevents more substantial fire damage to the carrier material. As a result, timber structures never fail spontaneously. Burning speed and retention of load-bearing capacity can be calculated.

Salt storage facility in Donauwörth, Germany. For maximum resistance capacity, no metal joiners were used, and all salt-touching surfaces are made from wood.

The risk of earthquakes had been grossly neglected in Central Europe until some years ago. Now, a dedicated European Standard has been developed to complement national regulations. A crucial factor to be taken into consideration when dimensioning a building’s load-bearing system is the horizontal forces unleashed by an earthquake that set entire buildings in motion. The weight of glulam structures compared to the weight of solid timber constructions is highly beneficial against this background. Rubner Holzbau’s experts analyse all relevant situational factors during the planning stage, and gather and perfectly reconcile all relevant aspects for conceptual design: floor plan, height of building, type of load-bearing system, bracing concept, selection of construction materials, mass distribution, and ductility of the load-bearing structures.
