Covered and elevated
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.
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.
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.
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.
What this treatment protects against
Protection built into
2200EX.
Warranty coverage and technical performance are related, but they are not the same thing. This is the documented protection story for the treated lumber within the approved product, application, and exposure scope.
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.Explore this protection ↗
Fungal-decay resistance
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.Explore this protection ↗
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.Explore this protection ↗Exterior-focused water repellency
Adds exterior-focused water repellency for approved above-ground applications. It is not a ground-contact claim or a substitute for proper detailing.
The documented 2200EX scope pairs preservative performance with exterior-focused water repellency under the specified installation and exposure conditions.What coverage follows
The written warranty
controls the details.
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.
