Abstract
Various insulations that employ magnetic clasps are disclosed herein. Insulation is formed as a panel of an insulation material. A magnetic clasp is attached to the panel. The magnetic clasp has a magnetic component that is substantially flush with a face of the panel. The magnetic component comprises a mixture of a ferromagnetic material and the insulation material.
Claims16
Insulation comprising:
- a panel having a face and a plurality of edges, the panel comprising polyisocyanurate;
- a magnetic strip set in the panel that extends across a length of the panel, wherein a face of the magnetic strip is flush with the face of the panel, and the magnetic strip comprises a ferromagnetic material and polyurea;
- a wedge that extends along the magnetic strip between the magnetic strip and the panel to aid attachment of the magnetic strip to the panel, wherein the wedge has a trapezoidal cross section, a top of the wedge is attached to the magnetic strip and a base of the wedge is wider than the magnetic strip;
- and
- an edge of the panel comprising a first shape that interlocks with a second shape of an edge of another panel, each of the first shape and the second shape being part of a tongue-and-groove or a ship-lap design.

An apparatus comprising:
- a panel comprising an insulation material;
- a magnetic clasp that is attached to the panel, the magnetic clasp comprising a plurality of layers;
- a first layer of the plurality of layers of the magnetic clasp, the first layer being a magnetic strip that is flush with a first face of the panel and extends across a length of the panel, wherein the first layer comprises polyurea and neodymium;
- a second layer that is attached to the first layer and the panel, and is embedded in the panel, the second layer comprising a trapezoidal cross section, a top of the second layer being attached to the magnetic strip and a base of the second layer being wider than the magnetic strip, wherein the second layer comprises polyurea;
- and
- an edge of the panel comprising a tongue-and-groove or a ship-lap design, wherein the edge of the panel is complementary with another edge of another panel.
