Tannin resin-boron for outdoor wood protection and fire retardancy
2011 - IRG/WP 11-30567
Boron in the form of boric acid is well known for its efficacy against wood destroying organisms, as well as for its high leachability from treated wood when in outside exposure. Moreover, due to the European directive 2008/58/EC, boric acid is only authorized at low levels. In order to keep considering boric acid as an interesting active ingredient for wood protection, the issue is now to fix it ...

Wood-leather panels – A biological, fire retardant building material
2012 - IRG/WP 12-40615
The poor flame retardant properties of wood-based products are among the severest obstacles, hindering its use in the commercial building sector. Recently, some attempts to improve the fire properties, relying on inflammable salts or reactive halogen compounds, have been presented, although they either cause problems with machining or embody harmful compounds (halogen derivates).
In this paper, ...

Laboratory investigation of fire protection coatings for creosote-treated timber railroad bridges
2014 - IRG/WP 14-30639
As the incidence of timber railroad bridge fires increases, so has the need to develop protective measures to reduce the risk from accidental ignitions primarily caused by hot metal objects. Of the six barrier treatments evaluated in the laboratory for their ability to protect timbers from fires sourced with ignition from hot metal objects only one intumescent coating provided adequate fire prote...

Fire protection of wooden facades in Norway
2015 - IRG/WP 15-40710
Wood products are experiencing a renaissance as construction material in Europe due to their environmental benefits. In Norwegian building design however, timber has always played an important role but has had its limitations in urban architecture. One of the reasons is a high demand to fire safety in dense house building and multi-story buildings. Though novel construction methods and fire safety...

Effects of wood protecting biofinish and linseed oil on fire behaviour and leachability of the fire retardant
2018 - IRG/WP 18-30728
A wood protecting biofinish is based on a protective and decorative fungal-based coating and a linseed oil impregnation (called Xyhlo biofinish). This biofinish enables the long-term use of wood in outdoor applications without using toxic chemicals.
The fire resistant properties of materials used in buildings are very important. Since Xyhlo biofinish is relatively new, only little information is ...

Yellow birch fire-protection using polyelectrolytes complexes
2020 - IRG/WP 20-30755
Fire protection has been a major challenge in wood construction for many years. The demand for high-performance, environmentally friendly treatments respecting the physical and chemical characteristics of the material has been accentuated in recent years. Halogenated fire-retardant (FR) compounds were commonly used from the 70’s for their low-cost and high efficiency. They are able to form radic...

Identifying compatible waterborne timber preservatives and fire retardants for use in a VPI system: a practical approach
2023 - IRG/WP 23-30796
To enhance the use and suitability of timber in all applications in both exterior and interior settings, timber typically needs to be treated with a preservative and/or a fire retardant chemical. Combining fire retardants with preservatives into a single treatment process has been a long-term aim of researchers in the timber preservative industry because of the significant logistic and economic ad...

Enhanced durability of bio-based materials for green building
2023 - IRG/WP 23-50382
Wood protection technologies provide tools to enhance the durability of bio-based materials for green building. Both wood and related bio-based material are regarded as eminent for green building. It allows to underpin several of the United Nations sustainable development goals and is regarded critical for the Green Deal objectives of the EU. Nevertheless, to enhance the potential it needs to be b...

Danish wood preservatives approval system with special focus on assessment of the environmental risks associated with industrial wood preservatives
2001 - IRG/WP 01-50166-01
The following is a description of the procedure used by the Danish Environmental Protection Agency to assess the environmental risks associated with preservatives used in the pressure impregnation of wood. The risk assessment covers issues considered to be of significance for the environment and which are adequately documented so as to allow an assessment. Such issues are persistence and mobility ...

Proposed method for out-of-ground contact trials of exterior joinery protection systems
1981 - IRG/WP 2157
Methods for testing the efficacy of preservative treatments for exterior joinery are described using the format of a European Standard. Commercially used treatments applied to jointed test units (L-joints) which are then protected by conventional finishes are exposed to normal outdoor hazards out of ground contact. Assessment is made a) by determining eventual failure through decay and b) by destr...

Granitgard used as a partial and perimeter barrier in the protection of buildings against subterranean termites
1995 - IRG/WP 95-10114
The graded granite subterranean termite physical barrier, commercially marketed as Granitgard, has a Certificate of National Accreditation issued by the Australian Building Codes Board, and is included in Australian Standards. After several years in developing the specifications and installation techniques for Granitgard, it may be used to protect almost all footing designs. Granitgard can be simp...

Fire resistance of preservative treated fence posts
1994 - IRG/WP 94-30033
Pine fence posts were pressure treated separately with CCA-C, CCA-wax, CCA-oil and creosote. Treated posts and untreated controls were planted in the ground in a randomised block design, weathered for six months and then subjected to a controlled burning test using two fuel loads. Creosote treatment increased the time that posts were alight whereas CCA treatment had no such effect. However, CCA tr...

Conservation of wooden cultural property
1994 - IRG/WP 94-30038
A survey of the conservation of wooden archtitectual monuments, art objects and archaeological finds is presented. Each of the three areas has typical conservation problems which reqire the use of selected wood preservatives and consolidation agents. Furthermore specific protection and consolidation methods are necessary. A precise damage diagnosis with non-destructive testing methods is the first...

Evidence supporting the use of termite baiting systems for long-term structural protection
2000 - IRG/WP 00-10377
The efficacy of the Sentricon Colony Elimination System containing Recruit II termite bait (0.5% hexaflumuron) in controlling active subterranean termite infestations has been demonstrated in numerous studies. This baiting system and other termite baiting systems are now widely used, and generally accepted, tools for remedial termite control in North America, Hawaii, and other parts of the world. ...

The biostatic effect of copper on decay of fire retardant-treated mining timber
1991 - IRG/WP 1507
Blocks of Eucalyptus grandis were treated with 20kg/m³ ammonium sulphate as fire retardant and challenged with Coriolus versicolor. Replicates were soil buried. A second set of blocks was treated with retardant and copper at 6.6 kg/m³ (ie 1% w/w), and challenged similarly. After 8 weeks weight losses produced by Coriolus versicolor in untreated, retardant treated and copper supplemented blocks w...

Termite and decay protection - A superficial barrier field test
1983 - IRG/WP 3257
Samples of Pinus radiata were given a superficial barrier treatment and installed in the ground at two sites for five years to observe termite and fungal attack. The three best treatments of the series were Denso petroleum tape, Koppers hot dip tar enamel, and Arquad 2C/75 alkyl ammonium compound. As new fungicides and insecticides become available they are being added to the test using the same s...

Efficacy of anhydrides as wood protection chemicals - II. Performance against soft rot fungi
1998 - IRG/WP 98-30174
Pine sapwood modified with various anhydrides and with butyl isocyanate was tested for its resistance to soft rot decay. Small stakes were exposed for 20 months in unsterile soil in a fungal cellar test.
Wood modified with butyl isocyanate performed better than any of the anhydrides tested, with a threshold level of protection (less than 3% weight loss) at 12% weight percent gain (WPG). Stakes ac...
