Wood can function as a capillary system due to its porous nature. Capillary action is the phenomenon where liquids move through narrow spaces, such as the tiny channels within wood. When wood comes into contact with water, whether through rain or moisture in the air, it absorbs the water through its fibers. The water then moves through the interconnected pore structure of the wood, spreading laterally and vertically. This capillary action enables wood to distribute moisture throughout its structure, which can affect its dimensional stability, strength, and durability.

Desiccation refers to the drying out or loss of moisture content within the wood fibers. This process can occur naturally over time due to exposure to air and environmental conditions, such as low humidity or prolonged sunlight. Desiccation can also result from human activities like kiln drying or air drying wood for various applications. As wood loses moisture, it may shrink, warp, crack, or become brittle, affecting its structural integrity and dimensional stability. While controlled desiccation is often necessary for manufacturing purposes, excessive or rapid drying can lead to defects and degradation in wood quality.

A type of plywood siding with vertical grooves that give it a wood-grain appearance. T1-11 is commonly used for exterior cladding on sheds, barns, and homes.
U
A type of electromagnetic radiation from the sun that can cause degradation of materials, especially paints and coatings, by breaking down their chemical bonds. UV protection is essential for materials exposed to sunlight to prevent fading and damage.
V
A large bee species native to the western United States that burrows into wood to create nests.
Volatile Organic Compounds (VOC)
Organic chemicals that evaporate at room temperature, often found in paints, adhesives, and sealants. VOCs can impact indoor air quality, so low-VOC or VOC-free products are preferred for healthier environments in construction.
W
The structural framework of a wall, typically composed of vertical studs, horizontal plates, and headers. Wall framing supports the building’s weight, provides shape, and creates cavities for insulation and utilities.
A gentle cleaning process that removes dirt, dust, and debris from surfaces. In painting, washing is often done to prepare surfaces for priming or painting.
A deck surface that is treated or constructed to prevent water penetration, protecting underlying materials from moisture damage. Waterproofing extends the deck’s lifespan and prevents water-related issues like mold and rot.
Watershed is the ability of flashing to divert water away from the home.
The quality of a material or structure to resist damage from weather elements like rain, wind, and sunlight. Weatherproofing protects materials and extends their lifespan.
A large bee species found in western North America, known for boring into wood to build nests.
The process by which water moves through porous materials by capillary action. In construction, wicking can cause moisture to rise in walls or foundations, potentially leading to damage.
Workers Compensation Insurance
Insurance providing wage replacement and medical benefits to employees injured on the job. In construction, it’s mandatory in most regions to protect both employers and workers.
X
A high-build, water-based primer designed to bond tightly to peeling or weathered surfaces, providing a smooth foundation for new paint.
The scientific genus name for carpenter bees, which are known for burrowing into wood.
A subfamily of bees that includes carpenter bees, known for their wood-boring habits.
Y
Z
A metal flashing shaped like the letter “Z” used to direct water away from joints in construction, particularly around doors, windows, and siding.
