  • Rigid foam insulation cutting system and method of use
    Patent number: 8656819
    Abstract: A cutting system and method of use for manually cutting rigid foam insulation panels; the present cutting system is operated manually and requires no electric power whatsoever; the cutting system includes a fully adjustable carriage assembly whereon a cutting blade is mounted for traversing the limits of its working surface; the cutting system provides a measuring scale having graduated indicia inscribed thereon for conveniently changing blade settings to accommodate different foam panel dimensions; the cutting system produces a uniformly accurate cut surface comparable to a factory-made surface without damaging the foil moisture barrier on the rigid foam panel; the cutting system completely eliminates the health and safety hazards created by airborne foam particulates that are produced by powered cutting of such rigid foam materials and thereby provides an environmentally-friendly building practice; and the present cutting system is completely portable enabling its setup and use at any construction site or l
