Can my glulam be exposed to the elements?

Untreated glulam that is normally used in residential construction is not recommended for exposed conditions. Although waterproof adhesives are used in the manufacturing of the beams, Douglas Fir and Southern Yellow Pine wood react unfavorably without proper care. Pressure treatment to American Wood Preservers Association (AWPA) standards, use of naturally decay-resistant wood species such as Alaska Yellow Cedar, or maintaining a weather-resistant surface coating is required.

What’s the difference between “wet-use” and “dry-use” conditions?

"Wet-use" and "dry-use" are terms associated with end-use conditions and their applicable design stresses. Intermittent exposure to the elements, followed by drying, still refers to "dry-use" even though the glulam beam could be described as wet. The technical measure of "wet" is consistent moisture content within the beam of greater than 16 percent. It is important to emphasize that a moisture content of 16 percent is rarely reached unless the beam is submerged in water, subjected to an artificially humid moisture condition, or in direct contact with the ground. Even in a highly humid artificial moisture environment, moisture content of 16 percent is only reached under unique combinations of relative humidity and temperature. For example, even a beam in an environment having 80 percent relative humidity and a temperature above 70 degrees Fahrenheit will not reach equilibrium moisture content of 16 percent. Because this combination is rarely found in the U.S., ambient-air conditions rarely result in wet-use conditions. However, pockets of moisture may collect even though the wood is protected from decay hazards by pressure treatment.
