Lumber Treating Terms
Lumber is used in so many applications, from construction to landscaping. This material, made up of timber cut into planks or boards, can be cut down to size or ground to a pulp, such as in the case of paper. A part of the forestry industry, lumber can also be treated at the mill to withstand the elements, which is crucial when used as decks, fencing, walls, and flooring. From pine and oak to cedar and plywood, lumber is an important resource and must be protected to provide the longest life. Wood can be sold in natural form or pressure treated, finished form from the lumber yard, timber mill or distributor. When you buy it from the yard or store, timber is usually pressure treated to combat fungi, mold, moisture, decay, and insects. Here are some top terms for lumber treating.
Plywood – Thin yet strong wooden board consisting of two or more layers that have been glued and pressed together. It is desirable because it resists cracking and warping. It’s also quite flexible.
Stain – A typical application for wood, stain consists of a colorant suspended or dissolved in a solvent. Polyurethane is an example of a colored finish, which does not penetrate the wood pores.
Non-toxic – Not harmful to humans and animals. Some treatments are not used anymore due to toxic qualities, while others are used for their harmless benefits.
Fire Retardant – Meant to guard against the spread of flames, fire retardant treated wood features a chemical application that forces the wood to remain stable within extremely high temperatures. It can be applied at the surface or under pressure.
Creosote – Typically seen on utility poles, pier posts, and railroad ties, this tar-based preservative is one of the oldest around but is not sold to the general public.
