Solutions

How can PENNGUARD help you?

New Construction


Pennguard Block provides cost effective corrosion protection on steel flues, but did you know you can save time and money installing Pennguard directly to the concrete windshield? Ask us how.

New Construction

Retrofit


When real estate is tight, consider investigating the feasibility of converting your existing stack to a wet stack, and avoid building a new chimney to serve your new FGD system. Ask about Pennguard’s successful application inside existing flues.

Retrofit

Ducts


The Pennguard Block Lining System provides cost effective corrosion protection for FGD absorber outlet ductwork. Ask about its 40-year track record.

Ducts

Wet Stacks


For wet stacks with excess moisture from the scrubbing process in the flue gas, Pennguard offers full chemical resistance and improved gas buoyancy and velocity. Ask about Pennguard’s proven performance in wet stacks.

Wet Stacks

Reheat/bypass


Pennguard withstands widely varying thermal conditions including wet stack, reheat and bypass. Ask how you can obtain highly desirable operating flexibility with Pennguard.

Reheat/Bypass

Spitting


The Pennguard Block’s unique surface texture keeps moisture from flowing up the liner, offering the chimney designer the most effective way to prevent wet stack spitting while maximizing gas velocity.

Spitting

Seismic zones


Pennguard lined chimneys have been documented to have survived significant earthquake events without sustaining damage, making Pennguard an obvious chimney lining candidate in seismically active zones. Inquire for details.

Seismic Zones

Leaking brick liners


Is flue gas leaking through the mortar joints in your ceramic brick liner, threatening the integrity of the reinforcing bands or concrete windshield? Ask how Pennguard applied directly to the inside of the ceramic brick liner can stop leaks.

Leaks

Fire protection


Pennguard protects chimneys from fire damage, reducing downtime after such an unfortunate event to get your plant back up and running quickly. Ask about Pennguard Block Lining Systems with FM Approval.

Fiberglass


Block the heat.

Apply PENNGUARD Block Lining over FRP chimneys and flues to extend temperature resistance and provide fire resistance. Ask how PENNGUARD handles the heat.

Fiberglass

Brick


Stop condensate leaks.

Retrofit leaking, structurally sound ceramic brick liners with PENNGUARD Block Lining System. Ask how PENNGUARD sticks to old bricks.

Brick

Steel


Prevent wet stack corrosion.

Line steel flues with time-tested PENNGUARD Block Lining System. Ask about FM Approval.

Steel

Concrete


Save construction time.

Skip the flues and apply PENNGUARD Block Lining System directly to the concrete windshield. Ask about cost advantages for seismic zones.
