High temperature seal

A seal for use in high temperature environments of a boiler assembly to remedy cracks and air leaks, said seal comprising:

• a high temperature silicone adhesive sealant layer;
• a first non-ceramic layer of high density fibers mounted to said silicone adhesive sealant layer;
• a first expanded metal layer mounted to said first non-ceramic layer;
• a first silicone cloth layer mounted to said first expanded metal layer;
• a metal reinforcement layer mounted to said first silicone cloth layer to provide structural integrity without the use of ceramic materials;
• a second expanded metal layer mounted to said metal reinforcement layer;
• a second non-ceramic layer of high density fibers mounted to said second expanded metal layer;
• a turbine mesh layer mounted to said second non-ceramic layer;
• a second silicone cloth layer mounted to said turbine mesh layer;
• a sealing castable applied over said second silicone cloth layer to provide a covering;
• and
• a high temperature bonding adhesive disposed between each layer following said first non-ceramic layer to bind the layers together.
