  2. 1. Norway spruce heartwood : properties related to outdoor use

    Author : Karin Sandberg; Lars-Olof Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Degradation of wood is a complex problem dependent on many parameters, but especially the presence of excessive amounts of water causes many problems.The objective of this work was to study the influence of various parameters on water absorption and desorption in Norway spruce (Picea abies (L.) Karst). READ MORE

  6. 4. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability

    Author : Tinh Sjökvist; Åsa Blom; Carsten Mai; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. READ MORE

  7. 5. Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

    Author : Maria Fredriksson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; moisture; durability; service life; microclimate; surface moisture; mositure content; Norway spruce; Picea abies; pressure plate; decay; growth ring width; heartwood;

    Abstract : This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. READ MORE
