As timber P. radiata is suitable for a wide variety of uses, [42] and has a resinous fragrance while being worked. [43] It holds screws and nails well and takes paint and stain without difficulty, and modern kiln dried timber is very easy to work. [44] It is about 1/3 heavier than dried western red cedar.
Acetylated wood is a type of modified wood that is produced through a chemical modification process. [1] It produced from a chemical reaction (named as acetylation), involving acetic anhydride and a modification process to make wood highly resistant to biological attacks by fungi and wood-boring insects and durable to environmental conditions.
Cross-laminated timber (CLT) is a subcategory of engineered wood panel product made from gluing together at least three layers of solid-sawn lumber at angles to each other. [ 1 ] [ 2 ] It is similar to plywood but with distinctively thicker laminations (or lamellae).
Both naturally and artificially occurring pine species can hybridize, combining their genetic material and sometimes creating hybrids that can be more or less vigorous than their parent species.
A sample of MDF. Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [1]
The Janka hardness test (English: / ˈ dʒ æ ŋ k ə /; [1] German:), created by Austrian-born American researcher Gabriel Janka (1864–1932), measures the resistance of a sample of wood to denting and wear.
For firewood, this is not an issue but for woodworking purposes, high stresses will cause the wood to crack and be unusable. Normal drying times to obtain minimal seasoning checks (cracks) in 25 mm (1 inch or 4/4 lumber) Red Oak ranges from 22 to 30 days, and in 8/4, (50 mm or 2 inch) it will range from 65 to 90 days.
Pinus elliottii, commonly known as slash pine, [2] [3] is a conifer tree native to the Southeastern United States.Slash pine is named after the "slashes" – swampy ground overgrown with trees and bushes – that constitute its habitat.
