When it comes to pressure treated wood, we do it right. Our inspectors examine every incoming load of lumber for bright, fresh, smooth appearance as well as for grade and moisture content. To eliminate rusting and scarring, we reband every bundle with color coded synthetic straps, positioned uniformly along the wood.
After treatment, we take boring samples from every charge and analyze them in our quality control laboratory to ensure they meet the standards of the American Wood Protection Association and the International Code Council. In addition a third party inspection agency, Timber Products Inspection Inc., certifies that we meet or exceed those standards. Not only do we store most of our pressure treated lumber under roof, but we have paved our yards and installed steel runners to help keep our stacks of lumber orderly and clean. The result: Our pressure treated lumber looks as bright when it leaves our plant as when it first arrived. Culpeper Wood Preservers is proud to partner with KOPPERS to supply you with the latest advancements in treated lumber. We treat wtih Micropro, CCA, and Borate.
Culpeper Aqua Shield is our optional built-in water repellent.
MCA (micronized copper azole) MicroPro®
MicroPro Revolutionary Technology
MicroPro® technology is a revolutionary way to pressure treat wood for decks, fences, landscaping and general construction uses. MicroPro pressure treated wood is treated with micronized copper preservatives, which help protect against termite damage and fungal decay. MicroPro offers many benefits including significantly improved corrosion performance. MicroPro treated wood products are US building code compliant.
Features & Benefits
- Lighter “Natural” color
- More natural wood appearance
- Better paint & stainability
- Better corrosion protection for exterior code-approved fasteners and hardware
- Approved for aluminum contact
- Building code compliant. ICC-ES Report, ESR-2240
- End uses include interior and exterior above ground, ground contact, and fresh water immersion
The KOPPERS MicroPro technology is the first treated wood process to be certified under Scientific Certification Systems Environmentally Preferable Product (EPP) program based on Life-Cycle Assessment.
Borate – Advance Guard® treated wood
Termites, decay fungi and other wood destroying organisms cause billions of dollars in damage to homes every year. However wood structural systems built with Advance Guard® Borate Pressure Treated Wood Products have long-term built-in protection against termites, including Formosan termites, fungal decay and many other wood destroying organisms. An additional benefit is that walls built with borate pressure treated wood limit populations of cockroaches and ants that may live in the wall system.
It is not suitable for applications exposed to the weather or in ground contact, and must be protected from exposure to liquid water.
