The central focus of this specialized division is the manufacturing of glued structural timber. This covers beam-shaped products such as glued laminated timber, glued laminated solid timber, finger jointed structural timber and various beams used in timber engineering as well as planar products such as cross laminated timber. The duties and responsibilities range from product development through to the execution of tests for approvals and to the inspection of manufacturing processes.
At present a project is concerned with the development of a complete system for contact-free, process integrated online quality control for all quality and strength-related production parameters for the manufacturing of glued structural products.
The application of radiation based technologies can considerably accelerate the curing of adhesives. Holzforschung Austria has a laboratory scale microwave tunnel which allows this technology to be investigated in detail.
Within the framework of this division, testing and inspection according to international, European and national standards and regulations is carried out. In cooperation with the West Coast Lumber Inspection Bureau (WCLIB), tests for the approval of glued products for America are performed. Furthermore this division is recognised as a Third Testing Organisation (TTO) by the Norwegian Wood Research Institute NTI (Norsk Treteknisk Institutt) for the execution of regular monitoring according to Japanese standards.
The accreditation (e.g. notification of control equipment) comprising the following test procedures:
Product group glued laminated timber:
Product group finger jointed structural timber:
Product group double and triple laminated beams:
Product group cross laminated timber:
Expert´s reports are prepared on the analysis of damage in different timber engineering components which are designed with by glued members. This is carried out mainly by assessing the facts at the site and by performing tests in the laboratory.
Glue master´s course: Every year the “glue master´s course” (a training courses for wood bonding) is offered. During this one week advanced training course, the fundamentals of wood bonding techniques, of timber grading, of the requirements pertaining to the manufacturing of glued structural timber products and their compliance with product standards are explained in detail. This course is primarily aimed at personnel from the glulam industry as well as from companies which work with glulam components.
