PENNGUARD 55 Block is a closed-cell borosilicate glass block. It is offered in 6- and 9-inch (150 and 225 mm) modules, with standard thicknesses of 1.5 or 2 inches (38 or 51 mm).
Centerpiece component of the PENNGUARD Block Lining System. Normally used with a substrate primer and PENNGUARD Adhesive/Membrane.
Offers a unique approach to protect flue gas handling equipment such as ductwork, chimneys and scrubber inlets and outlets found in coal fired power plants and other industrial facilities.
Used in hot process vessel applications. Low thermal conductivity reduces heat transfer to the underlying substrate. A 1-inch (25 mm) thickness may replace up to 10 inches (250 mm) of dense acid brick components in reducing the heat transfer to the substrate.
Protects from acid condensate corrosion
Excellent insulation even in saturated flue gas
Suitable for scrubbed, reheat and bypass gas conditions
Apply to steel, concrete, gunite, ceramic brick, fiber and glass reinforced plastic (FRP/GRP), and rubber membranes
Low thermal expansion
Low thermal conductivity
The system is capable of bridging cracks in concrete and ceramic brick substrates.
Suitable for vertical and overhead application
Lightweight, easy to cut
Factory Mutual (FM) test and approved for use in chimney flues
