“…The furfuryl alcohol, which has a sufficiently small molecular size, can impregnate wood cell walls and polymerize within the wood structure using a catalyst, heat or penetrating radiation [88]. Furfuryl alcohol originates from biomass waste [87] and is a renewable and natural material with no added metals or halogens [89]. It has been proven that furfurylated wood is an environmentally acceptable product [89,90].…”

“…Comparable property change results were also observed in other woods that had been furfurylated. The dimensional stability of furfurylated wood increased more significantly, and with higher modification levels, with the higher retention of polymerized furfuryl alcohol [49,87]. A 70 % furfuryl alcohol mixture was used to treat Pinus pinaster.…”

This paper comprehensively reviews the relevant literature and presents the methods and processes used to investigate the dimensional stabilization of wood using various modification techniques, including (a) hydrophobization of wood surfaces to block the entrance and exit of water; (b) impregnation treatment with bulking agents, such as resin and wax, to maintain wood in a swollen state and diminish dimensional changes caused by moisture; (c) chemical treatment with different chemical agents to reduce the hygroscopicity of the wood; and (d) high temperature heat treatment, which modifies wood components, reducing accessible hydroxyl groups and decreasing the possibility of water absorption. The results of dimensionally stabilizing wood via different treatments are interpreted and compared, and the effects of treating conditions and parameters on the dimensional changes of wood are analyzed.

“…The degradation processes are also influenced by the fact that wood is an anisotropic and nonhomogeneous material. Preservative treatment, impregnation, modification (Fojutowski et al, 2009;Welzbacher et al, 2009) and surface paintings deter the wood biodegradation processes and help to increase the durability and service life of wooden components (Lande et al, 2008). Heavy-duty preservatives that are used to treat wood materials for outdoor exposure have been dominated by chromated copper arsenate (CCA), creosote, coal tar, borates, pentachlorophenol and azole-based preservatives (TRADA, 2005).…”

Claddings or façades are the outer part of building envelopes. In this study, wooden claddings are exposed to natural and accelerated weathering. The natural climate exposure was performed at a field test site located in Trondheim,Norway. Accelerated climate exposure was performed in the laboratory in an Atlas SC600 MHG solar simulator.Attenuated total reflectance -Fourier transform infrared (ATR-FTIR) spectroscopy was used to characterise surfaces.The objective was to assess degradation by use of FTIR and thereby see how this may be applied to evaluate the service life of wood. Four types of wooden materials were studied; three untreated and one treated with chromated copper arsenate. Surface concentrated cellulose and lignin are the primary wood components used to determine the quality and durability of wood during ageing. It was found that treatment with preservative chemicals and surface roughness has definitive impacts on cladding surfaces and change to the chemical properties of the materials during ageing. The acceleration factor deduced from the Arrhenius equation shows that an increase in temperature lowers the service life of cellulose at a higher rate than the other wood components.

“…Since successful preservatives such as chromated copper arsenate (CCA), creosote, coal tar and chromium-based preservatives have been barred from use at places of human skin contact as specified by the American Wood Protection Association (AWPA), Health and Safety Executive (HSE) of United Kingdom and European standards (EN 351-1;CEN, 2007). Innovative methods like furfurylation have become an alternative for the wood preservative industries (Lande et al, 2004;Lande et al, 2008). Furfuryl alcohol is a bio-based product that is used to impregnate wood to impart toxicity against bio-organisms (Pilgard et al, 2010).…”
