Pressure Treated Wood in Residential Applications

Wood is our only renewable natural resource and provides thousands of products to improve our lives. Wood's advantages to the construction industry are many. It can be worked and fabricated on the job; it is strong; has a great insulation value and can be finished in a variety of ways; it has warmth and an eye-appealing tone. It has limitless possibilities for creative design inspirations, and is the most economical building material from the standpoint of both material and labor. Wood creates a congenial atmosphere in which to live and work. It is only natural that we preserve all these excellent characteristics for as long as possible, and above all, preserve wood to make it last as long, if not longer, than other building materials.

Fasteners and Wood Preservation

Residential Applications for Treated Wood

Fasteners, Connectors and Flashing for Pressure Treated Wood Treated wood is typically used in applications where it may be exposed to moisture for considerable periods so the fasteners and connectors must also be resistant to these conditions. In addition, most wood preservatives designed for exterior use contain copper that may react with the metals used to fabricate fasteners and connectors therefore, it is important to use the right type of fastener and/or connectors. Where treated wood is used in dry environments to prevent damage by wood-destroying insects, including termites, corrosion is of less concern. Users and specifiers should also be aware that corrosive industrial, or salt air, environments may also require the use of appropriate corrosion resistant metals.

Copper-based preservatives penetrate into and remain in pressure treated wood for a long time. However, some preservative may migrate from the preserved wood into surrounding soil over time and there may be incidental contact with skin during construction or use.

Follow the safe practices listed below when working with pressure treated wood. Specific work practices may vary depending on the environment and safety requirements of individual jobs.
