Effect of bio-resin from cashew nut shell liquid (CNSL) on decay resistance properties of wood
2013 - IRG/WP 13-40649
This study assesses the decay resistance properties of bio-resin modified wood against decay fungi of the Basidiomycota according to the EN 113 protocol. A bio-resin system was developed by ozonolysis process from cashew nut shell liquid (CNSL), a naturally occurring mixture of phenolics. Small wood blocks from sapwood of Scots pine (Pinus sylvestris), Obeche (Triplochiton scleroxylon) and Gmelina...

Applicability of wood durability testing methods to bio-based building materials
2015 - IRG/WP 15-20561
It is well known that organic materials may be susceptible to attack from a range of fungal organisms and any bio-based material used in locations where there is the possibility of microbiological activity must be expected to be able to withstand or prevent such attack. There are a wide range of test methods and standards in place to test susceptibility although most of these test individual compo...

Development of a rapid screening method to determine the susceptibility to mould growth of novel construction and insulation products
2015 - IRG/WP 15-20562
Wood-based materials are commonly used in building construction/insulation as a replacement for solid timber. However, these materials are susceptible to microbiological growth and different environmental conditions influence the vulnerability of wood-based materials. Moulds are a common problem found within homes and cause aesthetic damage, health problems and can increase material vulnerability ...

Introduction of the COST FP 1303 Cooperative Performance Test
2015 - IRG/WP 15-20567
COST Action FP 1303 “Performance of bio-based building materials” successfully started in October 2013 and an ambitious program was set up for the four year programme. COST Actions provide an excellent opportunity for collaborative research, e.g. in the frame of Round Robin tests. The idea of this respective test was to distribute a fairly simple test set up to as many places in Europe as poss...

Laboratory test to determine the effect on durability of combining biobased building materials with timber in construction
2017 - IRG/WP 17-20604
The use of Structural Insulated panels is a construction approach that is seeing more abundant use and is becoming a widely available method. Preformed units are usually a composite structure which often include a range of bio-based materials such as timber, wool or straw. Traditional laboratory based wood decay tests do not take into account this combination of biobased materials and it may be po...

Observed and projected changes in the climate based decay hazard of timber in the United Kingdom
2020 - IRG/WP 20-20665
The risk of microbiological attack on wood is determined by both material and climatic factors and indeed the hazard for a component is based on its intrinsic durability and the conditions in which it is used. The use of wood and organic materials in construction is increasing but ultimately all these materials will be susceptible to microbiological attack. The Scheffer Climate index applies clima...
