Fastener Recommendations for
 naturewood®  firepro™ advanceguard® osmose®

 

and Fastener Information:

Osmose® has recommended stainless steel or hot-dipped galvanized fasteners and hardware for use with CCA pressure treated wood products used in outdoor applications.  Like CCA, NatureWood pressure treated wood products are designed for long-term performance in outdoor applications and require the same high quality, corrosion-resistant nails, screws and hardware.  Due to the numerous types of hardware on the market, performance results may vary.  Direct contact of NatureWood preserved wood with aluminum is not recommended and should be avoided.  When using NatureWood preserved wood in close proximity to aluminum products, such as aluminum siding, flashing, furniture, and door and window frames, a 1/4" minimum space must be allowed between the NatureWood and the aluminum products.  Polyethylene or nylon spacers can be used to maintain the 1/4" spacing.  Another option is to use a polyethylene barrier, with a minimum thickness of 10 mils between the NatureWood preserved wood and the aluminum product to prevent direct contact of the wood and the aluminum.  For best results, use hot-dipped galvanized, stainless steel, or other fasteners and hardware as recommended by the hardware manufacturer.
