The study tour to Norway and Sweden was planned and coordinated by Russell C. Moody and Anton TenWolde from the U.S. Forest Products Laboratory. Forintek Canada Corp. was invited to participate on the tour with them with a view to beginning cooperative planning and research in areas of environmental concern, specifically moisture management in wood framed structures. The tour took place from August 17 to September 1, 1983. The author also stopped off in England to visit the British Research Establishment Laboratory in Princes Risborough and the TRADA laboratory in the same vicinity. Special appreciation is accorded to Mr. Torbjorn Schmidt at the Swedish Forest Products Laboratory in Stockholm and Mr. Erik Aasheim at the Norwegian Institute of Wood Technology. Their recommendations and assistance in setting up visits and tours was of great help. Mr. Schmidt also accompanied us in some of our journeys in Sweden and joined us in Norway for some of our meetings there.
