Abstract
Thermal insulated structures such as walls, ceilings and floors are produced for use in thermo-insulated cargo vans, box trucks, trailers, and other vehicles and compartments. A frame is built a frame in an area, and polyurethane foam insulation is sprayed onto the frame. The polyurethane foam insulation is cut, and then covered with polypropylene panels. The polypropylene panels are secured to the frame, and seams between the polypropylene panels are welded together. Plates are optionally secured to the edges of the panels.
Claims20
A method comprising:
- building a frame in an area;
- spraying an insulating foam composed of a first material onto the frame;
- shaping the foam;
- covering the shaped foam with a plurality of panels composed of a second material, thereby forming at least one seam between the plurality of panels;
- securing the plurality of panels to the frame;
- and
- welding together the at least one seam between the plurality of panels.
A method comprising:
- building a frame in an area;
- spraying an insulating foam composed of a first material onto the frame;
- cutting the foam;
- covering the cut foam with a plurality of panels composed of a second material, thereby forming at least one seam between the plurality of panels;
- securing the plurality of panels to the frame;
- and
- welding together the at least one seam between the plurality of panels.
A structure constructed by a method comprising:
- building a frame in an area;
