Stainless Steel Liners
05 / COMBUSTION ISOLATION

STAINLESS STEEL LINERS & UL 1777 certified flue relining

UL 1777 listed, heavy-gauge stainless steel chimney relining systems engineered to contain intense thermal shock, isolate lethal flue gases, and restore damaged venting shafts.

COMBUSTION ISOLATION
“The liner is the cardiovascular heart of the chimney. When clay tile liners crack, lethal carbon monoxide and extreme heat penetrate directly into home framing.”

Historic homes across New Jersey and Pennsylvania often feature unlined brick chimneys or terra-cotta clay tile flues fractured by chimney fires, thermal cycling, or acidic furnace condensation.

We install custom-sized, corrugated or smooth-wall 316Ti / 304 alloy stainless steel liner systems wrapped in ceramic insulation blankets, delivering airtight combustion isolation and optimal fireplace draft.

SAFETY STANDARD
UL 1777 LISTED RELINING

Certified for zero-clearance installations against combustible framing, rated for continuous 1,000°F operation and brief 2,100°F chimney fire spikes.

316Ti TITANIUM ALLOY CERAMIC INSULATION BLANKET
STANDARDIZED PROTOCOL

RELINING INSTALLATION PROTOCOL

01

Camera Flue Assessment

Level 2 camera inspection to measure flue clearances and remove fractured tile fragments.

02

Ceramic Wrap Insulation

Liner is blanket-wrapped in 1/2-inch high-density ceramic insulation to meet UL 1777 standards.

03

Vertical Stack Pull

Liner is carefully drawn through the chimney stack and locked to the appliance or firebox throat.

04

Top Plate & Termination

Stainless top plate sealed to the crown with a full-flue clamp and spark-arresting cap.

TECHNICAL INQUIRIES

FREQUENTLY ADDRESSED QUESTIONS

Clay tiles are brittle and cannot flex. Sudden chimney fires or rapid temperature shifts cause thermal shock fractures. Acidic moisture from high-efficiency gas furnaces also dissolves clay joints.
Stainless liners are insulated and sized specifically to the heating appliance or firebox opening, keeping flue gases warmer and moving upward faster without downdrafts.
Yes. To achieve the UL 1777 safety rating and comply with manufacturer warranties, stainless chimney liners must be wrapped in approved ceramic insulation blankets or cast in place with insulation mix.
