Owens Corning - Ceiling Batt Insulation

this is the owens-corning ceiling that insulation module this program will guide you through everything you need to know for professional installation of owens corning batt insulation and ceilings we will cover understanding ceiling types the installation process for ceilings under attics bats for attic floors and cathedral ceilings and best installation practices and techniques for each there are a few important steps to insulating a ceiling properly first there are two basic types of ceilings that you will insulate flat ceilings and cathedral ceilings you should also understand that most of the energy leaking from a home is through the ceiling of the top floor so it's especially important to do a great job of insulating here let's begin with flat ceilings under an adding in new construction where attics are to be insulated with batts you will typically install the insulation from below before the drywall is put up but before you begin insulating you'll have to protect the homes ventilation path a home needs to be well ventilated so it can breathe out excess heat and moisture failing to allow for proper ventilation can result in moisture damage to the homes roof to prevent this you will start by installing baffles like these rafter mates in every eve space to prevent the vents from being blocked by the insulation once the rafter mates are in place you can begin installing insulation simply push the bat straight up through the ceiling joists then pull it back down so the bat fits evenly in the space and is flush with a bottom of a joist it is important to install the bat properly so it recovers to the full label thickness and will deliver the full r-value if you are using faced bags make sure the facing goes toward the inside or the warm in witters side of the house also be certain the insulation covers the top plate where the ceiling meets the wall below and but separate pieces of insulation snug together so there are no gaps or spaces if local regulations call for stapling of faced insulation simply open the flange of the facing and staple it to the inside of the joist or the face of the stud every eight to twelve inches there usually will be some areas next to a wall for example with narrower than normal joist facing where you will need to cut the back to fit cut the bat about one inch wider than the cavity to make certain the bat fills the space completely and installs easily lighting fixtures and other elements that produce heat call for special treatment this is very important for fire safety install insulation at least three inches away from unrated recessed lighting fixtures depending on local building codes you may need to baffle around these lighting fixtures as well just cut and fit the baffle material around the fixture leaving at least three inches of space then fit the insulation snugly around the outside of the battle cutting the bat if necessary for a customized fit check each fixture carefully before you insulate around it if the fixture has the letters IC on it which stands for insulated ceiling you can insulate right up to and above the fixture making our job even easier if you have to work around metal chimneys gas water heater flus or other elements that produce heat give the insulation at least one inch of clearance at around Maestri chimneys or other areas that have small openings stop the space with pieces of unphased insulation you may also encounter other obstacles and flat ceilings such as electrical wiring junction boxes and ventilation fans if wiring protrudes into the cavity space you'll have to cut or split the back to fit around the wire if the wire runs near the top of the joist simply place your bat right over it for junction boxes and fans cut out of pinks of the bat for a custom fit around the obstruction following these simple guidelines you will have a flat ceiling insulated quickly and easily the second attic option is to install bats or rolls in the attic itself if you're working in the Attic be very careful as the drywall is thin and won't support your weight it's often a good idea to place a sturdy piece of plywood across the joists to have a place to stand or kneel while you work from up here you'll place the faced side of the insulation down toward the warm living area of the room below follow the same guidelines you just learn for fitting insulation around lighting fixtures heat sources and other obstructions finally before you leave the attic insulate the back of the access cover by stapling or gluing a custom cut piece of insulation to the back of the board let's move on to an increasingly popular ceiling style that doesn't have an attic above it the cathedral ceiling this peak design gives a room an open spacious Airy field but it also has special insulation needs for this lofty job you will need lots of safe secure scaffolding rafters and cathedral ceilings are usually made of two by tens or two by twelves owens corning makes two types of pink fiberglass bats especially for these types of rafters there's the eight and a quarter thick are 30c for two by tens and the ten and a quarter thick are a 38 C for two by twelves before you begin insulating install rafter mate baffles at the eve of every joist to make certain the vent space doesn't get blocked by the insulation if multiple baffles are needed install them one to two inches apart now push the bats up between the rafters until they are flush with a rafters edge do not push the bat up against the roof deck as this would block the necessary airflow our 30 C and our 38th C are designed to leave the standard 1 inch vent space when you install the bats flush with a face of the rafters be sure to but separate bats tightly together leaving no gaps between them make sure there is at least one inch of ventilation space between the entire bat and the roof deck for the full cavity run some local codes call for even more ventilation space so check out the requirements in your area if you're using something other than a cathedral bat or if your local codes call for more than one inch of vent space you will need to install baffles along the entire run of each rafter cavity where it is specified a poly vapor retarder can be installed over unfazed bags stretch the poly over the rafters and staple it in place overlap separate pieces of poly one full rafter space and staple securely for craft based our 30 C and our 38th C Cathedral Pat's face staple the flanges every eight to twelve inches installing owens-corning ceiling vents is really quite easy if you follow the guidelines we've given in this video our goal is the same as yours to make you and your company true insulation professions you
