Treated to help inhibit mold on the lumber surface, and to resist fungal decay and wood-destroying insects, including Formosan termites. For qualifying protected framing.
Whole-frame protection begins before the first wall is raised.
Protection should not stop at one plate or one vulnerable detail. RezWood™ 2200 creates a broader material strategy for the ordinary framing members that make up a building, helping protect the wood during construction and long after the finishes go on.

The foundational green RezWood™ treatment for qualifying dimensional framing—factory-applied protection against mold growth, fungal decay, and subterranean termites, including Formosan termites. Installation, field cuts, fasteners, and exposure details must follow TER 1511-09.
01
Protect more of the frame
2200 is designed for a whole-frame approach—from plates and studs to joists and rafters—within the documented use conditions for the selected lumber and application.
02
Frame with familiar material
The current third-party evaluation states that qualifying products do not require incising and retain the source lumber’s listed dry-use design stresses. Request the report through RezWood’s controlled technical-document process.
03
Use the right exposure detail
2200 covers UC1, UC2, and protected UC3A conditions. Exterior use must be protected from direct wetting and detailed with the required coating, flashing, drainage, and maintenance.

What we protect againstProduct-specific protection
Protection built into 2200.
The protection below applies to the treated lumber—not every material in the building—and only within the selected product's documented scope.
01
Mold-growth inhibition
Helps inhibit mold growth on the treated lumber. Moisture management, drying, and jobsite housekeeping still matter. The public technical evaluation documents mold-growth-inhibition testing using ASTM D3273 and ASTM D5590 methods.
Resists decay fungi within the documented exposure conditions. It does not replace flashing, drainage, ventilation, or maintenance. The public technical evaluation documents fungal-decay resistance for the approved lumber, application, and above-ground exposure scope.
Subterranean-termite resistance, including Formosan termites
Resists subterranean termites, including Formosan termites, within the current product scope. Untreated wood and cellulose remain outside the protection package. The public technical evaluation documents subterranean-termite resistance for eligible treated lumber within the approved application and exposure scope.
Part of the documented factory treatment for the selected lumber, application, exposure, and installation. The exact product documentation and approved project conditions control the claim.
Important context
Conventional pressure-treated lumber can also provide decay and insect resistance, and some products are specifically tagged for ground contact. RezWood 2200 is differentiated by its documented whole-frame package of mold-growth inhibition, decay resistance, insect resistance, low-emissions certification, and familiar dry-use framing performance within its approved exposures.
TestingCertifications + fit
Public technical record
Testing behind the treatment.
Review the standards, certifications and application limits for the selected lumber and project.
01
GREENGUARD Certified for low emissions
The supplied certification covers the finished 2200 system tested with wood under UL 2818 for low chemical emissions.
02
Third-party evaluated applications
Independent technical evaluation supports approved building-code applications and the documented preservative-performance claims without exposing proprietary formulation details.
03
Reaction-with-metals testing
AWPA E12 testing is included in the technical evaluation. Fasteners and connectors must still follow the exposure, building code, and hardware manufacturer's requirements.
04
Defined use categories
Evaluated for UC1, UC2, and protected UC3A conditions. RezWood 2200 is not represented as a ground-contact treatment.
Important context
Technical fit: UC1, UC2, and protected UC3A conditions. The TechWood evaluation covers multiple solid-sawn and engineered substrates. Texas Wood Tech currently offers RezWood™ in common dimensional lumber sizes; panel products, large beams, and truss programs are not part of the present offering.

Current RezWood™ availability
The TechWood evaluation covers multiple solid-sawn and engineered substrates. Texas Wood Tech currently offers RezWood™ in common dimensional lumber sizes; panel products, large beams, and truss programs are not part of the present offering.
Fire role: No fire classification claimed. Exposure: UC1, UC2, and protected UC3A conditions.
Water-based, mineral-centered protection
Choose fasteners for the treatment, exposure, building code and connector manufacturer’s guidance. RezWood™ 2200 has supplied certification for a system tested with wood under UL 2818 for low chemical emissions.
Cutting any lumber creates wood dust. Use dust control, eye protection and job-specific PPE. Never burn treated wood; confirm local reuse and disposal requirements.
DocumentsReports and warranty text
The written record for TW2200.
Warranty terms, evaluation support, and protection topics stay on their existing pages. Figures in those documents are unchanged.
CTH will warrant the treatment of wood components delivered and stored at construction sites for (4) four months, subject to the treated wood being stored off the ground, covered in its protective cover and safeguarded from accumulation of snow or standing water or water runoff.
02
Vertical framing · Up to 6 months · Unprotected framed state
CTH warrants the treatment of wood components of a covered structure for up to six (6) months in an unprotected vertical framed state, subject to proper documentation indicating completion of structure exterior wrapping or dry-in process.
03
Cured film surface · 5 years · Mold
The CTH Wood Treated Component is warranted to inhibit mold fungus growth/mycotoxin production on the cured surface of the film for 5 years.
04
Covered interior structures · 10 years · Decay and wood-ingesting insects
The CTH Wood Treated Component is warranted against wood-rot fungi decay and wood ingesting insects (including subterranean or Formosan termites) or carpenter ants, due to the failure of CTH WoodSurfaceFilm™ treatment while owned for 10 years. Such failure must render the CTH Wood Treated Component incapable of performing its intended purpose.
Important context
The Warranty Period begins on the date of purchase. This warranty is extended to the first owner after the original builder/general contractor purchases the material and is non-transferrable. Written notice is required within thirty (30) days. Conditions and exclusions apply.
