Abstract
Abstract An insulating support for supporting and protecting a pipe from ambient temperatures having a high density polyurethane insulation member which is semicircular in cross section and adapted to be positioned under the bottom of the pipe and which is bonded to a metal load-bearing semicircular member which is adapted to be supported from a support member, and a second insulation member being semicircular in cross section and adapted to be positioned over the top of the pipe and coact with the first member to insulate the pipe. The first member having a density of at least 7 pounds per cubic foot. The second member being polyurethane having a density of approximately 2 pounds per cubic foot. A vapor cover surrounding and bonded to the first and second members and the load bearing member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
An insulation support for supporting and protecting a pipe from ambient temperatures comprising: a first foamed plastic rigid load-bearing insulation member, said member being semicircular in cross section and adapted to be positioned under the bottom of the pipe and having a density of at least 7 pounds per cubic foot, a metal load-bearing member being arcuate in cross section and positioned against the bottom of the first plastic insulation member and bonded to the first member along the contacting surfaces between the metal member and the first member and spaced from the pipe and adapted to be supported from a pipe support, the length of the metal member being longer than the width of the pipe support; and a second foamed plastic insulation member, said second member being semicircular in cross section and adapted to be positioned over the top of the pipe and coact with the first member to enclose the pipe, said second member being of a less expensive material than the first member.
Claim 2
Dependent Claim
167 words
An insulation support for supporting and protecting a pipe from ambient temperatures comprising: a first foamed plastic rigid load-bearing insulation member, said member being semicircular in cross section and adapted to be positioned under the bottom of the pipe and having a density of at least 7 pounds per cubic foot, a metal load-bearing member being arcuate in cross section and positioned against the bottom of the first plastic insulation member and bonded to the first member along the contacting surfaces between the metal member and the first member and spaced from the pipe and adapted to be supported from a pipe support, the length of the metal member being longer than the width of the pipe support; and a second foamed plastic insulation member, said second member being semicircular in cross section and adapted to be positioned over the top of the pipe and coact with the first member to enclose the pipe, said second member being of a less expensive material than the first member.
Claim 3
Dependent Claim
23 words
