Pennguard
Protecting power plant chimneys
What is Pennguard?
The Pennguard Block Lining System uses inorganic closed-cell borosilicate glass blocks to provide complete protection against aggressive flue gas and condensates. It is widely used in chimneys, ducts, and flue gas cleaning installations. Pennguard linings last virtually maintenance-free for over 50 years.

Design
Pennguard is available in a variety of grades and thicknesses to meet the requirements of different chimney operations like FGD Wet stacks or highly corrosive SO3 condensates.
Closed-cell borosilicate glass Blocks are the cornerstone of the Pennguard Block Lining system, manufactured in the United States under stringent QC standards to provide long-term resistance to heavy corrosion.
The Borosilicate Blocks are set in our elastomeric Pennguard Adhesive Membrane, creating an impermeable acid resistant barrier.
With its unmatched long-term service life, Pennguard linings offer the best life cycle cost compared to any other chimney lining option.
Features
Chemically Resistant:
Completely resistant to corrosive gas and condensate, even with high SO₃ concentration.
Temperature Resistance:
Suitable for temperatures up to 300ºC.
Thermal Shock Resistance:
Tolerates heat cycling and frequent starts/stops without limits.
Low Weight:
Lightweight at 9-15 kg/m2, no anchors required.
Inorganic:
Virtually no maintenance, with a design life of 50+ years.

Applications
Steel
Pennguard is frequently applied on steel flues and ducts carrying flue gas in fossil fuel burning power plants.
Concrete
Pennguard is uniquely suitable to be applied directly to the concrete windshield, eliminating the requirement for internal steel flues.
Ceramic/fire Bricks
Ideal for rejuvenating old brick flues. Pennguard can be applied over uneven or leaking brick flues creating a liquid and gas-tight seal.
Organic coatings
Organic coatings are not suitable for long-term FGD operation in chimneys. Pennguard is compatible with most organic coatings, including Epoxy, Vinyl Ester, and glass flakes.
FRP
At the end of the life of FRP, Pennguard can extend the service life of Structurally sound FRP by an additional 25 years.
Performance
Pennguard is renowned as the world’s leading chimney lining, with a proven track record spanning over 40 years. It currently protects hundreds of chimneys across more than 35 countries.
Whether dealing with wet environments in Wet Limestone FGD stacks in coal-fired power plants or high-temperature, high-SO₃ conditions downstream of HFO boilers, Pennguard provides exceptional protection for your assets against the most aggressive environments.
