The wood technology team within BRE-CTTC has been particularly keen over recent months to promote the wider use of wet gluing, having evaluated the potential for two different adhesive systems (see case study, p14). It is also collaborating with five other European partners on a project aimed at enhancing the efficiency and competitiveness of wood based panel products used in the construction industry, and has been examining enhanced panel applications for agricultural fibres such as hemp, jute and flax. A door manufacturer is said to have registered an interest in the latter project on both cost and environmental grounds.
Within the BRE-CTTC’s timber engineering team, meanwhile, the current work schedule includes evaluation of new timber grading technologies.
The centre has played a leading role in developing and implementing methods for grading structural timber by visual and mechanical means. Last year, for example, it issued a review of current developments and presented latest information on the grading of timber in accordance with BS 5268 Part 2.
Finally, wood durability is an area in which BRE-CTTC has built a formidable reputation over many years. A key project, according to the section’s project manager Ed Suttie, is the search for more consistent and effective means of improving preservative penetration of spruce. It is also investigating – along with 17 industry and research partners across Europe – improved ways of stabilising wood surfaces against light-induced degradation.
Some key factors surrounding the photodegradation of woods have already been identified, he said, although the involvement of commercial sponsors prevents disclosure of any further details at present.
