You can definitely ask the question : ‘Why use glulam made from larch and Douglas fir?’
The answer is:
The HASSLACHER Group offers glulam made from larch and Douglas fir, two wood species characterized by high natural durability, aesthetically pleasing surfaces, and sustainability. Both wood species are ideal for use as garden timber and for load-bearing structures both indoors and, especially, outdoors. Glulam of both wood species is produced and quality-controlled according to the harmonized product standard EN 14080.
Larch – elegant, robust and weather-resistant
Properties: Hardest European softwood species, high natural durability.
Areas of application: Terraces, balconies, carports, supports, use for attractive interiors and round columns
Technical data:
Strength classes: GL24c and GL24h
Cross-sections: Heights: from 80 to 1,280 mm, other heights available as special components.
Widths: from 80 mm to 200 mm in 20 mm increments, special widths up to 280 mm available on request or through composite components (block bonding) or rod lamella technology.
Usage classes: Usage classes 1 to 3; in usage class 3, slats with a maximum thickness of 35 mm are used.
Durability class: 3 to 4 according to EN 350
Use class: GC 3.1 according to EN 335 with reduced sapwood content
Surface qualities: visual quality, industrial quality
Special feature: Ideal for structures exposed to the elements and outdoor areas
Intense color variation from reddish to brown.
HASSLACHER glulam made of larch wood for modern railway station construction
Some of the noteworthy projects that HASSLACHER has executed with their glulam :
HASSLACHER glulam made of larch wood for modern railway station construction
Cambridge South Station is a showcase project for sustainable and modern timber construction in the infrastructure sector. The building and platform canopies are constructed from glulam and cross-laminated timber (CLT) made of European larch, manufactured at the HASSLACHER Group’s sites in Kleinheubach and Stall im Mölltal (HASSLACHER Holzbauteile GmbH & Co. KG and NORITEC Holzindustrie GmbH).
Shell EV Hub in Fulham, London
The Shell EV Hub is a prime example of sustainable architecture and the use of high-quality glulam. For the exposed roof structures of this innovative charging hub, approximately 50 m³ of larch glulam, produced and highly prefabricated by the HASSLACHER Group, was used.
Douglas fir – load-bearing capacity paired with cost-efficiency and durability
Properties: High load-bearing capacity, dimensionally stable, reddish-brown colour
Areas of application: Canopies and pergolas, carports, premium wood for outdoor areas and gardens, for distinctive surfaces in other buildings.
Technical data:
Strength class: GL24h
Cross-sections: Heights from 80 mm to 1,280 mm
Widths from 100 mm to 200 mm in 20 mm increments (80 mm also available on request, billing unit 100 mm)
Lengths up to 24 meters
Special features: High fire resistance and chemical resistance; durability class of the heartwood against fungi: 3-4 according to EN 350
Sustainability in focus
Both types of wood bind carbon during their growth. Wood, a renewable raw material, comes from controlled sources, is harvested in strictly managed forests in compliance with all legal requirements, is fully utilized, and is suitable for circular economy use at the end of its service life as a load-bearing building material.
