Effects of intumescent formulation of vinyl acetate-based coating on flame-retardancy of thin painted red lauan (Parashorea spp.) plywood
2011 - IRG/WP 10-40537
Using intumescent coatings on wood-based materials is an effective method for fire safety. The intumescent coatings consist of four major components: (1) binder resin (BR), (2) carbonizing substance (CS), (3) foam producing substance (FPS) and (4) dehydrating agent (DA). Previous studies have demonstrated that the formulation of the four components strongly influences the performance of coatings. ...

Fire performance of the wood treated with retardant
2012 - IRG/WP 12-40591
To prepare the eco-friendly fire retardant wood, Japanese red pine (Pinus Densiflora), hemlock (Tsuga Heterophylla), and radiate pine (Pinus Radiata) were treated with inorganic chemicals, such as sodium silicate, ammonium phosphate, and ammonium boric acid. Different combination and concentration of those chemicals were injected by pressure treatment methods. The electron-beam treatment was used ...

Effects of nano-wollastonite impregnation on fire resistance and dimensional stability of Poplar wood
2012 - IRG/WP 12-40595
The fire-retardant properties of Nano-Wollastonite (NW) in poplar wood (Populus nigra) were determined in this study. Some physical properties such as water absorption, volumetric swelling and Anti-Swelling Efficiency (ASE) were also measured. Specimens were prepared according to the ISO 11925 standard for the fire-retarding properties, and ASTM D4446-2002 standard for the physical properties. Imp...

Mould growth on wood-based materials – a simulated in-service study
2012 - IRG/WP 12-20503
Ten different wood-based materials including preservative-treated wood, fire retardant-treated wood, modified wood, WPCs and untreated references of pine sapwood and spruce were placed in three different environments (an attic and two crawl spaces) for a period of 26 months. Mould growth was analysed at five to seven month intervals in an effort to map the growth development. The relative humidit...

Effect of electron beam irradiation on the fire retardant penetration into wood
2013 - IRG/WP 13-40642
Electron beam processing which can fast and easy change the nature of the material has received considerable attention recently. Studies using electron beam has been conducted in various fields and it has been applied in many industrial sectors. Electron beam has higher energy than other electromagnetic waves. It has excellent object permeability. It affects degradation of intermolecular cross-lin...

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 resistance of wood treated with potassium carbonate and silanes
2014 - IRG/WP 14-30657
This paper reports on the effect that organosilicon compounds and potassium carbonate and urea (PCU) have on wood flammability. The study focus on reducing wood flammability by promoting char formation through manipulation of the condensed phase decomposition chemistry. Potassium carbonate is known as an effective fire retardant, however it is easily leached out from wood and increases its hygrosc...

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...

Fire retardant treated wood products – Properties and uses
2016 - IRG/WP 16-30701
Wood is combustible, but can still perform very well in fire, especially for load bearing structures. However, visible wood surface may not fulfil the fire requirements in building codes and fire retardant treatments may be an option. The highest reaction to fire classification for combustible products may then be reached. However, the excellent fire performance of the virgin fire retardant treate...

Decay Resistance of MDF Manufactured with Huntite- Hydromagnesite and Zinc borate
2017 - IRG/WP 17-30710
The objective of this study was to evaluate the effectiveness of some mineral based fire retardants on decay resistance of Medium density fiberboard (MDF). Two mineral based chemicals containing (Huntite/Hydromagnesite) and zinc borate (ZB) were used at two different concentrations for panel manufacturing. Decay test of samples was performed according to EN 113 standard method. At the end of the t...

Thermal stability of a wood protective biofinish and the influence of flame retardants on Aureobasidium cells
2017 - IRG/WP 17-30716
In general there is an increasing need for sustainable resources, including sustainable building materials. Wood is one of these sustainable resources and is more used as an outdoor building material. Since unprotected wood will usually be degraded during outdoor exposure, many different protection systems are available on the market. Protection systems containing biocides however might create obs...

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 ...

The development of a suitable fire retardant for Radiata pine and other species
2019 - IRG/WP 19-30744
The use of fire retardant chemicals, with the overarching aim of creating a safer environment is not a new one, however it is generally under-developed and is often afflicted with an image of environmental and health issues and misperceived high costs. There is an ever-increasing need and desire for effective fire retardancy in timbers to inhibit or suppress the combustion process. This is paramou...

An overview of recent studies involving the thermal modification of hardwood species
2019 - IRG/WP 19-40869
This paper outlines recent activities related to the thermal modification of hardwood species, and particularly to tropical hardwood species. Timber demand is ever increasing, but this is being limited by the necessity to protect virgin forest stands. As such, the majority of supply of popular species is being met from juvenile short rotation stands. The limited age from these stands often plays a...

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...
