Power Preserved Glulam^® Beams & Columns (Treated Glulam)

The Power Preserved Glulam^® is durable, long-term solution for most exterior non-marine use structural applications.

Power Preserved Glulam® offers fast, easy, one-piece installation that’s more efficient than bolting or nailing multi-ply dimension or structural composite lumber members together.

Power Preserved Glulam® is offered in two preservative treatments: Clear-Guard™and Cop-Guard®

Clear-Guard™ is a colorless, solvent-based (low odor mineral spirits) preservative system containing Permethrin(insecticide) and IPBC (fungicide) which are active components in EPA-registered pesticides. Clear-Guard™ treated wood is effective against mildew, mold, decay organisms and various termites, including the Formosan Termite in above ground (UC3) applications.

Cop-Guard® (Copper Naphthenate preservative) has a green color. Cop-Guard® treated wood products are available in a range of retentions for above ground use (UC3), ground contact (UC4) and severe exposure (UC4). It is effective against mildew, mold, decay organisms and various termites, including the Formosan Termite.

Both preservatives are applied to Power Preserved Glulam® through vacuum pressure impregnation per American Wood Protection Associations (AWPA) Standards.

With a 25-year warranty from the treater, high strength-to-weight ratio, and long span capabilities, Power Preserved Glulam® is an excellent choice for decks, boardwalks, pergolas, covered porches and demanding environments such as bridges, highway sound barriers, railroad cross ties, and floating docks.

FEMA Fact Sheet #13 - Wood-Pile-to-Beam Connections - FEMA produced this series of 31 fact sheets to provide technical guidance and recommendations concerning the construction of coastal residential buildings. The fact sheets present information aimed at improving the performance of buildings subject to flood and wind forces in coastal environments. Photographs and drawings illustrate National Flood Insurance Program (NFIP) regulatory requirements, the proper sitting of coastal buildings, and recommended design and construction practices for building components, including structural connections, the building envelope, and utilities. Many of the fact sheets also include lists of FEMA and other resources that provide more information about the topics discussed. Where appropriate, resources are accompanied by active web links.
