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.
