Why Smoothcore® Triple Lock® liner is superior to other liners
The Triple Lock® Smoothcore® construction is a two-ply exhaust pipe. The corrugated outer wall is very crush resistant during installation. The inner wall is smooth, which improves draft flow rate by eliminating turbulence inherent with other corrugated liners.
• Resists corrosion by reducing the drag on the flow of condensate through the liner
• Less soot accumulation
• Greater flex radius
• Exceptional strength
• Air-tight and leakproof
• Deadens noise from vibration
• Lightweight, easily to handle and easily flexed
• Very resistant to puncture
• High air pressure rating
