Summum Pro 6" Insulated Wall Thimble
Telescopic Airtight Pass-Through for Combustible Walls (8" to 15 ½") — Model SC-6IWT-2-P
Safely pass your chimney through exterior framed walls while protecting your building envelope from sub-zero drafts and moisture leaks with the official Summum Pro 6" Insulated Wall Thimble (Model #SC-6IWT-2-P). Precision-engineered in Canada, this heavy-duty telescoping assembly is mandatory whenever a Summum Pro 6" insulated chimney pipe penetrates a combustible framed wall horizontally. Designed with a smooth telescoping sleeve that adjusts to wall thicknesses from 8 inches to 15 ½ inches, it incorporates factory-engineered insulation and airtight vapor seals—ensuring code-compliant 2-inch airspace clearance while completely stopping cold outdoor air infiltration, wall cavity heat loss, and interior condensation in modern energy-efficient homes and winterized cabins.
Summum Pro 6" Telescoping Wall Thimble Framing Profile, Flanges & Airspace Dimensions
- Telescopic 8" to 15 ½" Wall Adjustability: Two-piece telescoping sleeve slides smoothly to fit standard 2x4, 2x6, and 2x8 framed walls, including exterior wall assemblies with thick rigid foam insulation, rain-screen strapping, or brick veneer.
- Built-In Energy-Efficient Thermal Barrier: Packed with factory non-combustible ceramic insulation and precision vapor seals that stop cold drafts from migrating into wall cavities, preventing interior drywall condensation in Canadian winter weather.
- Guaranteed 2" Code Clearance to Combustibles: Built-in structural standoffs ensure the mandatory 2-inch airspace clearance between the outer chimney casing and combustible wall framing is automatically and permanently maintained.
- Heavy Stainless & Galvanized Construction: Fabricated from durable 430 stainless steel on the interior pass-through and corrosion-resistant galvanized steel on the exterior sleeve for lifetime structural longevity.
- Precision Snug Fit on 6" Chimneys: Tailored specifically to encase the 9-inch outer casing diameter of Summum Pro 6" insulated chimney pipe connecting directly to the exterior cleanout tee.
- CAN/ULC-S629 Certified System Component: Fully tested and certified by OMNI Laboratories to meet strict 2100°F (1150°C) factory-built chimney standards across Canada.
- Limited Lifetime Warranty: Backed by Summum Pro's generous 10-year 100% component replacement warranty and 50% replacement coverage thereafter when installed by a certified WETT or APC technician.
