Wood is a widely used construction material. Wood is mainly 4 types according to heartwood, density and strength. All woods have different properties. The properties are important when selecting a wood. Wood should be treated to extend timber life and prevent insect attacks and fungal decays. Mainly wood is used for furniture and roof. The usage of the wood is varied with the strength and workability of the wood. Wood defects can reduce the quality and strength of the wood. It can be damaged by human, animal and environmental activities. But it can protect using coatings and sealants. <\/p>\n\n\n\n

Wood is mainly 4 types. Those are softwood, hardwood, engineered wood and exotic wood. Wood has categorised into main 4 types according to the heartwood, density and strength of the wood. The denser area of the wood is named as heartwood. The lower dense area is sapwood. Denser woods are less workable but more durable, with less damage and defects. <\/p>\n\n\n\n

Wood is processed to lumbers in mainly 4 methods. Those are live-sawn, plain-sawn, quarter sawn and rift sawn. Live-sawn is the lowest waste-generated method. Plain sawn is the most used method for lumber cutting. Rift sawn is a complicated method of lumber cutting. Quarter-sawn provides stronger lumbers but it is more expensive. <\/p>\n\n\n\n

Wood characteristics and behaviours are based on the wood’s properties. The main 10 properties of the wood are wood strength, structure, density, specific gravity, knots, grain, colour, growth rings and water content. Each of these properties directly affects the strength, stability and quality of the wood. Therefore these properties are useful in wood selection.<\/p>\n\n\n\n

Wood should be treated before using it. Wood treatments can improve mainly these 03 things such as durability, insect resistance, and strength. The main 3 types of treatments are pressure treatment, chemical treatment, and heat treatment. Pressure-treated and chemically treated wood is long lasting about 10-40 years, and heat-treated wood will last long about 15-30 years.  The usage of the wood varied with the hardness of the wood. Softwood is used for furniture, packaging, paper and pulps and door and windows mainly. Hardwood is used for furniture, flooring, and musical instruments mainly.<\/p>\n\n\n\n

Wood has defects. Those defects are considered as any abnormality or irregularity found in the structure or appearance of wood. The main 5 wood defects are knots, checks, splits, warping, and rotting. Defects are formed during the tree growth period and various environmental conditions. Defects can reduce the strength and stability of the wood. Small defects can be fixed by using fillers or epoxy resins easily. But larger defects need more filling, cutting and sanding processes.<\/p>\n\n\n\n

Due to the defects and user behaviours, wood damage are occurred. Mainly wood is damaged by insects, environments, physical impacts, radiation and chemical damage. You can protect the wood mainly by doing regular cleaning, moisture control, pest prevention, and regular maintenance.<\/p>\n\n\n\n
