Abstract

The joint is formed from a flexible sheet of the material to which is applied a coating of silicone resin, the sheet being held tightly by at least two edges on the elements to be joined, the silicone-layer being applied to the side of the sheet not exposed to the flue gases. The sheet may be held in position by bolting it to the walls using P.T.F.E. washers. The edge of the sheet may be folded back surrounding a flexible cord, and joint is flexible, resistant to temps. up to 250 degrees C, smoke tight and long lasting.
