The roof opening can optionally be covered with a flap, and is preferably overhung by an eve. The housing can be made of a cardboard or other foldable or readily cut panel, internally lined with fiberglass or other insulation. The insulation can advantageously extend below the bottom of the panel. Panels can be manufactured and shipped in a flattened shipping configuration. Assembly can use chemical, mechanical, or any other suitable mechanical connectors. Once installed, mats, bats, blown or any other type of insulation can be disposed about the housing. ## Claims ### Claim 1 A housing comprising: an open bottom when fully configured for use; at least first and second side walls; at least one of the side walls providing insulation with an R value of at least 0.1; and a tapered roof. ### Claim 2 (depends on 1) The housing of claim 1, further comprising a first opening and wherein the roof comprises a first eve portion that overhangs the first opening. ### Claim 3 (depends on 2) The housing of claim 2, wherein the roof comprises a second eve portion that overhangs a second opening. ### Claim 4 (depends on 1) The housing of claim 1, further comprising the panel having third and fourth side walls, wherein the roof is continuous with at least three of the first, second, third, and fourth side walls. ### Claim 5 (depends on 1) The housing of claim 1, further comprising a beveled edge disposed between the first and second side walls. ### Claim 6 (depends on 1) The housing of claim 1, wherein the first side wall comprises (a) a panel and (b) a sheet of insulation inside the panel, having an R-value of at least 0.25 ### Claim 7 (depends on 6) The housing of claim 6, wherein the sheet of insulation extends farther down the first side than the panel. ### Claim 8 (depends on 6) The housing of claim 6, further comprising at least one cutout in a bottom of the sheet of insulation. ### Claim 9 (depends on 6) The housing of claim 6, wherein the panel comprises a paper. ### Claim 10 (depends on 6) The housing of claim 6, wherein the panel has a spontaneous open air combustion temperature between 350° F. and 500° F. (about 177° C. and 260° C.), inclusive. ### Claim 11 (depends on 1) The housing of claim 1, further comprising a first opening and a flap disposed over the first opening. ### Claim 12 A method of insulating a ceiling can, comprising: providing a housing having an insulated first side wall, an open bottom, and a tapered roof; placing the housing over the can such that the first side wall is at least 3″ from the can; and ensuring that the roof has at least a first opening for egress of hot air. ### Claim 13 (depends on 12) The method of claim 12, further comprising ensuring that the roof has an overhang over the first opening. ### Claim 14 (depends on 12) The method of claim 12, further comprising ensuring that all portions of the housing are at least 3″ from the can. ### Claim 15 (depends on 12) The method of claim 12, further comprising folding back a bottom portion of the first side wall. ### Claim 16 (depends on 15) The method of claim 15, wherein the ceiling can is disposed near a joist, and further comprising attaching the folded back bottom portion to the joist using a fastener. ### Claim 17 (depends on 12) The method of claim 12, wherein the ceiling can is disposed near a joist, and further comprising attaching the housing to the joist using a tie strip. ### Claim 18 (depends on 12) The method of claim 12, wherein the ceiling can is powered by a wire, and the first side wall defines a passage, and further comprising running the wire through the passage. ### Claim 19 (depends on 12) The method of claim 12, further comprising shipping the housing in a flattened shipping configuration. ### Claim 20 (depends on 12) The method of claim 12, further comprising disposing a blown type of insulation about the housing.
