Pipe insulation system
A modular shell system of a hard insulation material fabricated in a geometric shape that encapsulates a pipe in insulation is provided. In an attic installation for example, the entire insulation component is inserted over a pipe and into the space between the building structural wood framing members resting on the interior sheathing below. By placing a series of these interlocking insulating modules along a pipe that is run perpendicular to the building construction members, the piping is encapsulated in a continuous insulating system along its entire length. This design facilitates natural heat flow into the pipe with an open pipe slot cavity in the insulating module that allows natural convection heat to pass up through the elongated piping slot, allowing it to come into contact with this piping.
1. An insulation system for insulating piping contained in a ceiling structure having a plurality of adjacent framing members supporting interior sheathing on a lower surface thereof and at least one pipe on an upper surface thereof, said plurality of adjacent framing members and interior sheathing forming a space therebetween, said space having a warm side adjacent said interior sheathing the insulation system comprising:
at least one rigid insulation block having a proximal end, a distal end and front and rear surfaces extending along a length of said insulation block between said proximal and distal ends said length corresponding to a spacing between said plurality of adjacent framing members;
a cavity formed within said insulation block spaced at a distance from said front surface corresponding to a height of said plurality of adjacent framing members and extending along the length of said block from said proximal end to said distal end; and
a wedge shaped slot having a wider opening at said front surface and extending to a narrower opening at said cavity, wherein said cavity receives said at least one pipe therein such that a portion of said at least one pipe is exposed adjacent said front surface of said insulation block, wherein heat passing through said ceiling structure is focused through said slot onto said at least one pipe.
2. The insulation system of claim 1 , said space having a cold side, said insulation system being received within said space with said rear surface adjacent said cold side and said front surface adjacent said warm side.
3. The insulation system of claim 1 , further comprising:
a continuous thermally conductive layer covering an interior surface of said cavity, said slot and at least a portion of said front surface of said block proximate said slot, said thermally conductive layer being in thermal communication with said interior sheathing.
4. The insulation system of claim 1 , said at least one block further comprising a plurality of blocks having interfitting mating formations extending from said proximal and distal ends that interfit with corresponding formations on adjacent blocks and extend over said upper surface of said plurality of adjacent framing members when received in an installed position.
5. The insulation system of claim 1 , further comprising a layer of insulation installed in said cavity beneath said at least one pipe to prevent condensation. b 666
