SOUND AND THERMAL INSULATING NON-WOVEN SYNTHETIC SHEET MATERIAL |
摘要 |
A non-woven synthetic sheet material for use in sound insulation and/or thermal insulation is described. The sheet material is a felt or mat of substantially uniform synthetic fiber thickness and defines opposed flat surfaces. The sheet material is needle-punched from at least one of the opposed flat surfaces thereof to cause the synthetic fibers to intertwine to form a pliable sound and/or thermal insulating sheet. The insulating sheet has a density in the range of from about 100 to 1500 g/m2 and a homogeneous integrity resistant to fragmentation. Preferably a polymeric film is interconnected to a surface of the synthetic fiber sheet by a further needle punch step the polymeric film is preferably a metalized polyethylene film. The material has a multitude of uses in the construction industry. The felt may also be provided in strip form for use in the framing of wooden structures to sound insulate interconnected parts. |
