Developing from the family craft business founded in 1929, the Jacob Group specialises in the manufacture of wooden components for the construction industry. Its manufacturing activities are concentrated around two distinct areas:
- The manufacture of “Roof Trusses”: JACOB Structures Bois, a subsidiary, manufactures industrialised roof trusses and traditional, digitally cut roof timbers
- The manufacture of “Pre-fabricated framework, walls and coverings for buildings”:
POBI, another subsidiary, offers a complete range of manufactured pre-fabricated components (floors, walls and roof parts) finished in the factory and destined for professionals working in the construction of private houses, social housing, professional premises and collective buildings.

Glulam has been called the grandfather of engineering wood, because the first glulam engineered timber was produced over a century ago....log before I Joists of LVL.
Today, glulam is still a fresh choice for designers because of its strength, economy and ambiance. Straight, tapered or curved, it can be ordered in a range of sizes for all types of applications. Its strength for long spans can provide unobstructed view with minimal need for columns or posts.
Glued laminated wood arches, beams and trusses are also a renewable resource, because US foresters plant 5 million trees each day to insure a future supply of wood. this contrasts with steel and concrete, which deplete natural resources.
The combination of high strength and large sizes makes glulam timbers ideal as main load carrying members which can span over 100 feet. In residential construction, glulam beams are commonly used for headers and beams supporting large portions of floor and roof systems.
When glulam materials arrive at the jobsite prefinished or pre-drilled , the delivered product is the finished product. this makes glulam unique as a structural component for many kinds of buildings. other types of framing members arrive on site in raw form, and require additional cladding to create the final production.
Glulam timbers are available in four appearance grades; premium, architectural, industrial and framing.

ven the most difficult shapes are not a problem and this opens up unlimited design possibilities. Curves, bends, angles and slopes of all types mean you can give free rein to your imagination. We can handle any shape with our know-how and sophisticated technology.
All types of arches and cambers
Long lengths (up to 32.5 m)
Even 3-dimensional bends are possible
Lamella thicknesses are adapted to the shape and intended use
Continuous testing by in-house laboratory and external institutions
Finger-jointing of the smallest cross-sections to large-scale constructions
Finger-joints executed in line with architectural and static requirements
On request, Kaufmann can also provide you with valuable support by means of expert advice and ready to install execution.

Standard glulam beams are glued-timber crosssections of various strength classes: GL24 (BS11), GL28 (BS14), GL32 (BS16), GL36 (BS18), in two surface qualities: Visual or industrial quality. They are without camber and have a lamella thickness of up to 45 mm.
|
|
|
To complement our Glulam product range, we can also supply all types of curved beams and supports from our partners. The appropriate shape can be freely selected to suit the architectural application. Because a combination of various lamella thicknesses can be used, all radii from approx. 2 m upwards are possible. Radii < 6.50 m, however may be subject to longer lead-times.

Our 1.9E BoozerBeam-IJC%u2122 is a high strength structural glulam beam that is made of Southern Yellow Pine lumber and waterproof adhesive. It is clearly stronger and stiffer
than 1.7E TimberStrand, 1.8E LVL and 1.8E/24F glulam beams. Made of the finest southern yellow pine lumber and waterproof adhesive available. It can be seamlessly integrated into any engineered wood system. Substituted for LVL and PSL in I-joist systems, the
1.9E BoozerBeam%u2122 is much more cost effective because it is both stronger and lower in cost.

Our BoozerLam is a high strength structural glulam beam that is made from the finest E-rated dense southern yellow pine lamstock and waterproof adhesives. Since it's rated to be at least as strong and as stiff as is PSL and LVL and also l-joist compatible in all its dimensions, it can be seamlessly integrated into any engineered wood system.
Exceptional value in cost vs. performance.
I-Joist compatible depths for seamless substitution.
Available in any length up to 52'.
Individual wrapping with water resistant paper available.
Wax coated with LiquiSeal%u2122.
As strong and as stiff as is PSL and LVL.
Made of the finest E-rated dense southern yellow pine lumber and waterproof adhesive available.
Quality inspected by the American Institute of Timber Construction (AITC).
2.1E BoozerLam%u2122 is available in widths of:
3 1/2" 5 1/4" 5 1/2" 7" 7 1/4"
and depths that are compatible with l-joists, conventional framing and traditional glulam.
