<p>An expandable insulation blanket (10) includes a body of insulation material (12) having a first edge (14) and a second edge (16) wherein the first and second edges are opposite one another. A first slit (18) defines a first hinge point (20) between a first end (21) of the first slit and the first edge, a second hinge point (22) between a second end (23) of the first slit and the second edge and a third hinge point (24) between a third end (43) of the first slit and the first edge. A first hinge body (26) is outlined by the first slit, the first hinge point and the third hinge point. A second slit (28) extends across the first hinge body and defines a fourth hinge point (30) between the second slit and the first slit. When expanded the insulation body includes a substantially triangular shaped opening (62).</p> |
