Local preservation with difluoride pills: Life-time of preservative
1998 - IRG/WP 98-40127
A brief history of the situation in the Netherlands with respect to the preservation of joinery is given. Already in the eighties in the Netherlands many spruce window frames were treated with difluoride pills. One of the possible disadvantages of this kind of diffusing preservatives is the high leaching rate found in laboratory situations. The leaching rate in practice is influenced by many facto...

The use of bifluorides-diffusion in remedial treatments
1983 - IRG/WP 3256
A description is given about the experience to date of a 14 years' development to bring bifluorides-diffusion from laboratory evaluation to commercial service application. The described treatment is an adjunct to good design and not a replacement for it. The process is also used with an injection method for the remedial treatment of premature decayed external joinery....

Wooden windows, avoidance of damage via constructional measures
1990 - IRG/WP 3591
Increasing awareness of the environment reinforces the trend to use wood as a building material for windows in modern building constructions. Wood is a natural building and construction material. Under certain circumstances such as persistent humidity exceeding 30%, wood is rapidly degraded by decay fungi into CO2 and inorganic salts. The cost caused by damage (e.g. replacement of windows) represe...

Fluoride woodpill
1987 - IRG/WP 3431
Decay problems of spruce joinery in the Netherlands in the 1960's and 1970's led to the introduction of preservative treatment. Because of the known penetration difficulties with Spruce, the results of the treatments were not always successful. The fact that the decay was found only in the joints led to development of the philosophy of "local preservation" of the joints in remedi...

The efficacy of remedial treatments for controlling fungal decay in window millwork used in the United States
1987 - IRG/WP 3432
Conventional window millwork was subjected to basidiomycete decay by inoculation and sampled for active growth of the decay fungus before and eight months after remedial preservative treatment with fused disodium octaborate rods (IMPEL) at boric acid levels of 1.5 and 4.0 kg/m³ or liquid bifluoride injections (IMPROSOL) at 1 kg/m³. The elimination of decay fungus after remedial treatment was nea...

A chemical and mycological evaluation of fused borate rods and a borate/glycol solution for remedial treatment of window joinery
1983 - IRG/WP 3225
The possibility of using fused borate rods (Impel Borpatron) and a borate/glycol solution (Boracol-40) for depot impregnation of window joinery has been examined in a co-operative project between The Swedish Forest Products Research Laboratory, The Swedish University of Agricultural Sciences and Prolignum AB. The fused Impel rod is a glassy rod composed of disodium octaborate which readily dissolv...

Raising of the grain and deformation of Scots pine (Pinus sylvestris) treated with water-borne preservatives
1987 - IRG/WP 3456
In Sweden partial impregnation to 10 mm depth of the pine sapwood (class B in the Nordic preservation standard) of joineries was introduced during the seventies. To avoid product quality problems, organic solvent-based systems have been used. However, the Swedish industry today has problems with organic solvents, mainly for environmental reasons. We have studied raising of the grain and deformatio...

Decay in window joinery in Sweden
1977 - IRG/WP 390
Systematic investigations of decay in window joinery in Sweden have not been undertaken until very recently. One might guess that one of the reasons for the minor interest is that this type of joinery did not rot strikingly faster than people expected. In the last 10-15 years, however, house owners, tenantowners, building societies and others have repeatedly argued that windows do rot more than in...

Window test. Direct testing of wood resistance to decay: A study of its fitness, its reliability and its accelerating factor
1984 - IRG/WP 2219
This is the results of an experiment using the window-test specimens, exposing the specimens to three different types of testing procedure: 1. Natural infestation in the open air; 2. Artificial infestation and exposure in the open air; 3. Artificial infestation in a green-house. The results show good similiraties of the three parallel tests in term of decay, and assess the reliability of the windo...

Chemical and biological investigations of double-vacuum treated windows after 5 years in service
1983 - IRG/WP 3219
In 1980 The Swedish Wood Preservation Institute initiated an investigation to study the degradation of TBTO and possible fungal attack in double-vacuum treated window joinery in service during 5 years. A hospital in Gothenburg was chosen that was built during 1969 to 1976. Both untreated and double-vacuum treated windows of Pinus sylvestris were used. A brown alkyl oil type paint (Nordsjö system ...

Chemical and biological investigations of double-vacuum treated windows after 7½ years in service
1985 - IRG/WP 3339
Earlier investigations of double-vacuum treated windows after five years in service have shown that tributyltin oxide (TBTO) degrades to di- and monobutyltin compounds and that the resistance of the wood against decay decreases. An investigation 2.5 years later of the same windows shows that the degradation of TBTO proceeds fast. After 7.5 years in service only 15-35% of the remaining organotin co...

Whitewood - An external joinery timber?
1975 - IRG/WP 253
The timber used traditionally for softwood joinery in the UK is redwood (Pinus sylvestris). In the past its ready availability in the desired sizes and quality and its durability in service encouraged little competition. However, the past decade has seen some erosion of this position, particularly through the increased proportion of sapwood in redwood supplies. Since the sapwood is less durable th...

Frequency of fungal decay in softwood windows in Germany
2010 - IRG/WP 10-10725
Knowing how often fungal decay occurs is a fundamental basis for general recommendations of preservative measures. To optimize the German recommendations for chemical wood preservation of windows made out of pine or spruce more than 2000 windows have been inspected. All windows had an opaque coating and were between 2 and 17 years old. The selection of the inspected windows was kept as randomly as...

In-service performance of wood claddings and windows – a Norwegian survey
2018 - IRG/WP 18-20632
The overall aim of the study was to strengthen the empirical data on decay frequency and in-service performance of claddings and windows in Norway. Data from a survey of claddings and windows from 38 Norwegian houses is presented. The main findings for wooden claddings: 1) predominance of decay was detected in east facing claddings, while the largest decayed areas were located on south facing clad...

Reuse of discarded wood and alternative wood species to replace spruce in the development of wooden windows for complete disassembly – REWINNUSE
2023 - IRG/WP 23-30785
The REWINNUSE project focuses on the reuse of discarded wood and alternative wood species and on the development of wooden windows that can be easily disassembled into their basic components. In cooperation with the project partners (M Sora, the University of Ljubljana Biotechnical Faculty (BF), the Norwegian Institute of Bioeconomy - NIBIO and the Slovenian Forestry Institute (GIS)), the project ...
