Abstract
A non-woven sheet material for use in building construction and having acoustical thermal and waterproof properties is described. The sheet material comprises a non-woven felt having a polymeric film secured over a surface thereof. The polymeric film has an outer aluminized reflective surface coating adhered thereto. The sheet material has a weight density in the range of from about 30 to 1500 g/m.sup.2 and a homogeneous mechanical integrity resistance to fragmentation by the application of traction forces applied thereto during its intended use. The sheet material is capable of being used with the outer aluminum reflective surface facing upwardly or downwardly of an enclosure space to provide acoustical and/or thermal insulation to the space and to provide an impervious barrier.
