Stainless Steel Chimneys
SpetsGroup NVP manufactures three types of chimneys: single-wall, double-wall (sandwich) and coaxial — from stainless steel AISI 430, AISI 304 or AISI 316. In-house production, 2-year warranty, turnkey installation.
Single-wall chimneys
Designed for use inside existing brick or stone flue channels. A thin stainless steel liner protects the inner surface from aggressive condensate. Wall thickness: 0.5–0.6 mm for gas boilers, 0.8–1 mm for other fuels. Supplied in 1 m modular sections.
Double-wall (sandwich) chimneys
Three-layer construction: inner stainless steel pipe, 32 mm mineral wool insulation, outer stainless steel casing. Prevents heat loss and condensate formation. Recommended for freestanding installation outside the building or in unheated spaces.
Get a priceCoaxial chimneys
"Pipe-in-pipe" system for boilers with sealed combustion chambers. Simultaneously extracts flue gases and supplies fresh air to the burner. Compact design can be installed horizontally or vertically. Manufactured from AISI 304 and AISI 316 steel.
Components and accessories
We manufacture a full set of components for every chimney type: adapters, tees with condensate drain, inspection hatches, brackets, decorative covers and roof penetrations. All elements are made from matching materials with the same wall thickness.
