Patent number: 5356446Abstract: The present invention relates to a method of providing thermal insulation and fire-resistance to buildings, by filling voids or spaces in and around structural members with a low density thermally insulating and fire-resistant cementitious composition containing a high proportion of a relatively smooth-surfaced, vesicular, expanded perlite. The method includes placing a flexible, woven, fire-resistant bag in the space to be filled, so as to act as a containment vessel, pumping a cementitious composition into the bag to fill a space by conforming to the shape of the space, while the bag simultaneously contains the cementitious composition in the desired position, and allowing the composition to cure into a lightweight, fire-resistant, and thermally insulating concrete. The method is particularly useful in and directed to remedial, post-construction applications in occupied buildings.Type: GrantFiled: July 7, 1993Date of Patent: October 18, 1994Inventors: David A. Smetana, Alfonzo L. Wilson, Richard J. Lenczewski, Said Dimitry
