Random coefficient mixed models were developed to predict vertical and horizontal density variations in stems of Scots pine and Norway spruce. Modeling and validation were based on investigations of 132 …
Liquid water absorption in small specimens of acrylic coated cladding was investigated before and after one year of outdoor exposure, and before and after 3000 h of exposure in a …
The influence of wood properties on cracking, blistering, and flaking of a 3-layer acrylic coating system was investigated in a natural weathering test from autumn 2007 to spring 2011. The …

Wooden facades without coatings have become popular in Norway, especially for large buildings like multi-story houses (Hundhausen, 2013). To obtain a quick and even greying, a one-off treatment with iron …
Hygrothermal materials change their moisture content (MC) dependent on the ambient climate. This material property to absorb and desorb moisture and thereby to moderate the indoor variations in relative humidity …
The term knot yellowing, also known as knot bleeding, describes the spotty, yellow-brownish discolorationof coated softwood surfaces. Scots pine wood (Pinus sylvestris L.) is particularly susceptible. Knotyellowing is ascribed to …
Measuring the dry film thickness of wood coatings is of great importance in quality control. The dry film thickness is negatively cor-related with the formation of coating defects like cracking …
Wood has been experiencing a recent renaissance as construction material mainly due to its environmental assets. However, wood has the reputation of being prone to contamination and difficult to clean, …
Fire retardant treatments facilitate wood-based products to reach the highest classification for combustible products, class B-s1,d0 (Östman et al. 2010). The drawback of several fire retardants (FR) is their poor …
