Explain How Fungal Decay of Lumber Can Be Prevented
FSP or Fiber Saturation Point is the percentage of water content in a wood member when all free water water contained in cell cavities has evaporated but the cell fibers are fully saturated with water. If lumber is dried to 6-8 percent moisture content for indoor uses or 15-18 percent for outdoor uses it should not decay if the moisture content is maintained below 20 percent. Deterioration Of Timber Thermal Insulation Northern Architecture Explain how fungal decay may be prevented. . Most wood decay can be prevented by simply keeping the wood dry. If the wood is water-soaked the supply of air to the interior of a piece may not be adequate to support development of typi-. When dry rot occurs the fungi break down cellulose and hemicellulose the components which give the wood strength and resilience. Prevent buckling of studs in non-load-bearing walls. The wood is left weakened and brittle often with a blocky appearance. Soft...
