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...

Binder-free, fire-resistant, light-weight fiberboard materials encrusted with expandable graphite and borax
2024 - IRG/WP 24-20714
Despite abundant data on innovative fire protection technologies tailored for wood and lignocellulosic materials, the prevailing approach revolves around the formulation of fire retardant solutions employing water-soluble salts, e.g., phosphorus or boron compounds. On the other hand, additives fostering the formation of a char layer during the combustion of lignocellulosic materials as a non-leach...

Manufacturing of bamboo hybrids with high strength, superior fire retardancy, and dimensional stability
2024 - IRG/WP 24-30808
Bamboo, renowned for its rapid growth, high strength-to-weight ratio, and eco-friendly attributes, has found extensive use in decorative building materials and glue-laminated beams. However, the inherent challenges of dimensional instability and flammability in natural bamboo restrict its broad application. This research introduces a range of environmentally friendly techniques aimed at producing ...

Towards eco-friendly fire retardant of wood - exploring fungal biomineralization
2025 - IRG/WP 25-11052
Timber is a strong, durable, aesthetically pleasing and sustainable building material but its combustibility represents a safety threat. Commonly used fire and flame retardants are often environmentally unfriendly, while safety cladding is labour intensive and covers the wood, decreasing the aesthetic appeal of the building. Mineralisation of wood with calcium carbonate has been shown to be a prom...

Enhancing the Fire Resistance of Spruce Wood through Treatment and Additive Application: Small Flame Test Method
2025 - IRG/WP 25-20737
Spruce panels treated by spraying with Burnblock® spray, were tested using “Small flame test method” according to EN ISO 11925-2:2011. The fire retardant product from Burnblock ApS is reported by the Danish company to be bioderived and non-toxic. The results for the untreated planed spruce showed moderate flammability whereas the Burn Block treated panels exhibited exceptional fire resistance...

CIOL Wood - Scientific Innovations in Wood Modification for Enhanced Performance and Usage
2025 - IRG/WP 25-20743
CIOL® is a wood modification technology designed as an environmentally friendly alternative to traditional wood preservatives. Utilising a biobased formulation based on sorbitol and citric acid, CIOL® enhances wood's chemical structure, improving its durability, stability, and resistance to decay. This paper provides an overview of the advancements made in CIOL® technology, including its improv...

Investigation of a commercial fire-retardant additive on particleboard properties
2025 - IRG/WP 25-20755
Fire resistance of wood-based panels is in addition to mechanical and sorption properties, an important property when considering its usability for construction applications. Increased fire resistance is achieved through fire retardant addition during panel production or by spraying fire-retardant on already finished panel. A potential downside of fire-retardant addition during panel production ca...

The impact of common fire retardancy salts and minerals on further properties of wood
2025 - IRG/WP 25-30821
Wood has become an increasingly important construction material. To ensure fire safety, fire retardants are widely applied. Recent research focuses on environmentally friendly fire retardants with strong fixation. Phosphate-based salts like diammonium hydrogen phosphate show high fire protection potential but are highly leachable due to their good water solubility. As a newer trend mineralisation ...

Mineral-wood composites with improved fire properties and durability prepared through MgCO3-based mineralization
2025 - IRG/WP 25-30823
New mineral-wood composites that demonstrate improved fire properties and higher resistance to selected fungi have been prepared using an environmentally-friendly mineralisation process involving impregnation with an aqueous magnesium acetoacetate solution. MgCO3-based compounds are formed in situ, deep within the wood’s structure. We show that the new mineralisation method overcomes wood’s lo...

Enhancing strength, fire and biological resistance of wood through structural and chemical modification
2025 - IRG/WP 25-30831
Wood, a renewable and versatile biopolymer, has been a fundamental material to construct traditional and advanced composites for building construction, furniture, transparent composites, and various other applications. Despite its many advantages, including its aesthetic appeal, workability, and relatively low cost, wood possesses inherent limitations such as susceptibility to biological, flame an...

Optimising properties of citric acid-sorbitol bonded particleboards with added ammonium dihydrogen phosphate as fire retardant
2025 - IRG/WP 25-41033
Due to the adverse health effects of formaldehyde-based adhesives and their fossil origin, there is an ongoing search for appropriate bio-based adhesives for particleboards. Although there are some possible solutions, their use in construction is limited partly due to their low moisture resistance and flammability. The latter can be improved by adding various fire retardants. A particleboard with ...

Analysis of A Wooden Structure Damaged in a Fire – The Wooden Granary at Zaprice, Kamnik
2025 - IRG/WP 25-41049
Zaprice Open-Air Museum in Kamnik, Slovenia, features several granaries dating to the early 19th century, forming part of the national Cultural Heritage Register (EID: 1-09881). One of the two-chamber wooden granaries, constructed in 1828, suffered significant fire damage in December 2024. The objective of this study was to evaluate the extent of the damage, assess the structural integrity, and id...
