INSTALLATION INSTRUCTIONS FOR FIBER GLASS BATTS AND ROLLS

A Berkshire Hathaway Company

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

. 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 ﬁber glass.

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

installed their required materials prior to the ﬁber glass being installed. Proper air sealing should

be complete prior to ﬁber glass batt installation to insure full performance of the ﬁber glass batts.

Verify all holes and seams between sheet goods such as drywall, sheathing, and subﬂooring at the

building envelope are sealed with durable caulk, tape, and/or foam sealants.

Energy Star Certiﬁcation for Products

Order #6881100

Project #12CA35908

Johns Manville ﬁber glass batt and roll insulation is easy to install and does not require a certiﬁed

installer. Wherever insulation is installed in a building, it is very important that it ﬁts snugly on all

sides. If the insulation is too long for a space, cut it to the correct size. If it is too short, cut a piece

to ﬁll the void. For unfaced batts, friction ﬁt it into the cavities. If using faced batts, they may in

friction ﬁt or the ﬂanges may be stapled to the wood studs. Use a Bostitch, Arrow or similar manual

staple gun and

" or

" staples, using enough staples to hold the insulation ﬁrmly in place and

avoid gaps and ﬁshmouths.

CEILINGS AND ATTICS Insulating Ceilings: Ceiling insulation provides essential sound control between floors in your home. Properly insulating the ceilings 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. Any walls that leak water must be repaired before insulating. 2.

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.

WALLS Insulating Basements: Basement walls and walls in unvented crawl spaces should be insulated to help prevent substantial heat loss. (A crawl space is an unfinished, accessible area below the first floor of a building. An unvented crawl space is part of the basement while a vented crawl space opens to the outside.) Unframed, exterior basement walls should be insulated with blanket insulation, which can be installed horizontally or vertically.

CRAWL SPACES How to Insulate a Vented Crawl Space If the sub-floor is already in place, the insulation is installed from below, much as it is installed in ceilings. 1. C over the ground with sheets of six-mil plastic film. The sheets should overlap each other by approximately twelve inches, and extend a few inches up the walls. 2. T ape the film in place at the walls and hold the seams in place with tape, scrap lumber, or rocks. After the ground is covered, you’re ready to install the insulation. 3.

FLOORS Floor Insulation: Underfloor means the floor above an unheated crawl space or basement. Once the underfloors are properly insulated, you will increase the overall comfort of your home because underfloor insulation provides valuable sound control and thermal control. The procedure for installing insulation in underfloors 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 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 Ductwork: To insulate around heat ducts in ceilings or floors, cover ducts with insulation so the air temperature in the ducts can be maintained more efficiently. In basement ceilings, whenever possible, pull the insulation behind any ductwork. Insulating Non-standard Size Spaces and Narrow Cavities: You will need to trim and piece the insulation. 1.
