FAQsView More

What is camber?

Camber is a "crown" purposely built into a glulam at the time of manufacture. It is most often desired in long span applications to counteract deflection. Camber does not affect the strength of the beam. Residential stock beams are normally made in either 5000' radius or zero camber, while other engineered wood products are zero camber. Most residential spans are less than 24', and the camber derived from a 5000' radius falls inside industry accepted manufacturing tolerances for zero camber beams. These glulams are increasingly popular because they contribute to a "flat" framing system without humps.

What effect does mold have on plywood?

A warm, wet, or humid environment provides ideal conditions for the development of mold and mildew on a variety of surfaces, including wood structural panels. Mold and mildew are terms commonly used interchangeably, although mold is often described as black, blue, green, and red fungal growths, while mildew is described as whitish growths. The color depends on the infecting organism and the type and moisture condition of the nutrient. For example, white mold is commonly found on water-saturated laboratory test samples of wood stored at room temperatures overnight. Mold and mildew alone do not deteriorate wood, but decay may occur under similar high-moisture conditions. These conditions normally do not include humid air, which may produce mold and mildew, but not the degree of moisture content that causes wood decay. As a general rule, wood will not decay if it is kept air dry. Allowing the wood to dry to a moisture content not exceeding 20 percent stops further growth of mold or mildew fungi. The surface growth often can be easily brushed or surfaced off. Additionally, a chemical spray solution of 10 percent household bleach and water will kill the fungi. However, under renewed moist conditions, new infestation may occur.
