Abstract
Abstract Fibrous insulating bodies are joined and sealed to each other by tabs extending from their margins and having precoated, nontackey and activatable adhesive coatings which can be activated when convenient, upon installation of the bodies in the position and condition of ultimate use, the adhesive is activated by localized application of activator fluid to the precoated tab areas and engagement of the tackey tab surfaces with the surface of the adjacent body with which the seal is to be made. Augmenting seals can be made by separate sheet or tape elements having a face precoated with the activatable adhesive.
