Knotted wood is any wood which contains a high proportion of knots. Knots occur in wood where branches are present in the source tree. Knots negatively affect the strength of wood and make it more difficult to work with. Wood with many knots is therefore generally graded lower than a comparable species with less knots. The resulting irregular pattern within the grain is a desirable product for some, and hence is used commonly in architecture and construction. Wood products containing knots can be polished, weathered, or smoothed, and can be stained to create a variety of finishes. Knotted timber is used in cladding, facades, flooring, landscape decking, and interior design.
A seamless wood texture with a knotted timber surface. Seamless textures can be tiled repeatedly across a surface without visible seams making them useful for architectural drawings and 3D models. This image can be used as a SketchUp texture, Revit material or imported into Photoshop for use in 2D illustrations. A high resolution version of this texture is available, as well as CAD hatches and PBR maps with Architextures Pro.
