ISOLIERSTRUKTUR.

摘要

An insulating structure is provided for which comprises: (1) insulating material comprising one or more high-density, thermal/acoustical layers of highly bonded fibers; and (2) a chemically resistant, impermeable envelope enclosing said insulating material. Preferably, the insulating material also comprises one or more acoustical layers of loosely woven fiber cloth having openings correlated to the wavelength of the sound to be attenuated. Preferably the insulating structures of the subject invention comprise sealed mounting flanges extending from the edges of the envelope and means for removably attaching the insulation to the surface to be insulated.
