Site Preparation:

Safety glasses with side shields are recommended to keep dust out of the eyes. Use ear protection

(earplugs, hood or earmuffs) to prevent airborne dust or ﬁbers from entering the ear, if necessary.

Leather or cotton gloves should be worn to protect against mechanical abrasion. Optional: wear a

NIOSH-certiﬁed disposable or reusable particulate respirator with efﬁciency rating of N95 or higher

(per 42 CFR 84) except required when dust or ﬁber concentrations exceed the applicable exposure

limits of dust 15 mg/m

(*OSHA 1910.1000 Table Z-3). Wear a cap, a loose-ﬁtting, long-sleeved shirt

and long pants to protect skin from irritation. Exposed skin areas should be washed with soap and

water after handling or working with mineral ﬁber insulation.

Other trades, including but not limited to, electrical, plumbing, and mechanical should have already

installed their required materials prior to the mineral ﬁber batts being installed. Proper air sealing

should be completed prior to mineral ﬁber batt installation to insure full performance of the mineral

ﬁber batts. The insulation must be keep clean and dry during transport, storage and installation.

CEILINGS AND ATTICS Insulating Ceilings: Ceiling insulation provides essential sound control and thermal performance between floors in your home. Insulating the ceiling above the top story is the most important area to control heat loss, and insulating the ceilings between stories will make your home a more peaceful and quiet place because it will ensure that footsteps and other sounds do not migrate to other rooms. How to Install Insulation In Ceilings 1. Seal around all penetrations in band joists.

WALLS Insulating Exterior Walls: An exterior wall is any wall that faces outside or otherwise separates conditioned spaces from unconditioned spaces. These walls should be thoroughly insulated in order to create the all-important thermal envelope around your living space. Properly insulated exterior walls make all the difference between a comfortable, energy-efficient home and a drafty one. Take time to fit the insulation carefully so heat cannot escape in the winter and the inside stays cool in the summer.

FLOORS Floor Insulation: Under floor means the floor above an unheated crawl space or basement. Once the under floors are properly insulated, you will increase the overall comfort of your home because under floor insulation provides valuable sound control and thermal control. The procedure for installing insulation in under floor applications is similar to installing ceiling insulation. Follow the installation tips below to ensure that you do a professional job. How to Install Underfloor Insulation 1.

SPECIAL CONSIDERATIONS, CRITICAL DETAILS & TIPS: Keep all insulation at least 3 inches (75 mm) away from combustible sources such as chimneys, non-IC fixtures and heated (furnace, water heater, etc.) flue pipes. Insulating Around Electrical: Installing insulation around junction boxes that house electrical receptacles and switches, and around wiring in walls and ceilings requires some special techniques. When cutting insulation around wiring, be sure to keep your utility knife clear of the wires.

SPECIAL CONSIDERATIONS, CRITICAL DETAILS & TIPS: Insulating Around Windows (continued): Use small scraps of insulation to fill in the cracks around windows and doors. Separate the insulation from the facing and use a putty knife or screwdriver to work it into spaces between studs or anywhere you can see daylight. This is an important quality step on every job. Basement Windows – If there are windows in your basement wall, you can make a metal window frame and attach it to the walls around the window.
