First, some temporary flooring should be laid across
the joists to provide some footing, and a temporary work light should be installed. Next, install attic vents, such as Owens Corning Raft-R-Mate®
attic rafter vents, to ensure proper air flow in your attic. This helps prevent ice dams in the winter and
heat build up in the summer. |
 |
Lay the insulation blanket at the outer edge of the attic space and work toward
the center. This allows for more headroom in the center of the space, where cutting and fitting
can be done. It's also a good idea not to get "insulated into a corner" where it will be hard to
get back to the attic entryway. |
 |
If the joist cavities are completely filled, lay the new insulation in long runs
perpendicular to the direction of the joists, and use leftover pieces for small spaces. If the
cavity is not completely filled, use the appropriate thickness of insulation to fill it to the top of the joist cavities,
then add an additional layer of insulation in the perpendicular direction. |
 |
The insulation should extend far enough to cover the tops of the exterior walls,
but should not block the flow of air from the eave vents. To make sure the eave vents aren't blocked,
Owens Corning Raft-R-Mate® attic vents or baffles should be installed to provide unrestricted air
flow from the eave vents to the other attic vents. |
 |
Insulation should be kept three inches away from recessed lighting fixtures unless the fixture is
marked "I.C." (Insulated Ceiling), which is designed for direct contact with the insulation. If insulation is placed
over an unrated fixture, it may cause the fixture to overheat and perhaps start a fire. Also, the insulation should
always be installed at least three inches away from any metal chimneys, gas water heater flues or other heat-producing
devices. |
 |
Around masonry chimneys or other areas that have small openings, stuff these spaces with small
pieces of unfaced insulation, which will not burn. |
