If
You're building or buying a home, consider the contemporary
basement alternative-a permanent wood Foundation, or PWF. Just What exactly is a
Permanent Wood Foundation? It's a load-bearing Lumber-framed foundation wall
sheathed with plywood. All lumber and plywood components are pressure-treated to
withstand decay from moisture and damage by termites. Southern Pine dimension
lumber is the strongest structural species, the ideal material for PWF
construction. Southern Pine is also the preferred species when
pressure-treatment with preservatives is required, because of it's treatability.
The unique
cellular structure of Southern Pine permits deep, uniform penetration
of the preservative, rendering the wood useless as a food source for
termites. |

| A
Proven, Practical System: |

| Durability
of the PWF system is demonstrated by long-term ground tests conducted by the
USDA's Forest Service. In these tests, pressure-treated wood has withstood
severe decay and termite conditions over decades of exposure. PWF walls are
designedto resist and distribute earth, wind and seismic loads and stresses that
may crack other types of foundations. The Permanent Wood Foundation is accepted
by the major model building codes, by federal agencies, and by lending, home
warranty, and fire insurance institutions. And it has been proven by years of
success in more than 300,000 homes and other structures throughout the U.S. Like
conventional wood frame walls, the wood foundation is adaptable to virtually any
design. The PWF fits a variety of floor plans and can be used for both level and
sloping sites. |

|
| All
lumber and plywood is pressure treated with a waterborne preservative to
withstand severe decay conditions. Specific treating industry standards and
quality control for PWF materials are established. Southern Pine is the
preferred wood species for the pressure treatment process. |

|
 |
PWF
wall panels can be prefabricated or built at the site. Installation is fast and
simple, using the same framing crew that builds the rest of the house. |

| A
complete PWF basement, ready for first floor framing. Basement wall framing
easily accepts insulation to meet the new energy codes now enforced in many
states. |

|
 |
A
treated wood floor is the ideal partner for the PWF, enhancing the comfort of
below-ground living areas. |
|
Virtually
any home design-traditional or contemporary- can benefit from the many
advantages of a PWF. Room additions are simplified too.
