This product may help earn points under the following checklist item:ħ.1.4 Products used for home are manufactured within 800 km (1 point for each 2 products-maximum of 5 points). Flexible: forms readily around corners and curved surfaces.
Resilient: bonded glass fibres will not pull apart during normal applications and resist settling, breakdown, and sagging from vibration. Durable: will not rot, mildew, or otherwise deteriorate. Non-corrosive: does not accelerate corrosion of pipes, wiring, or metal studs. Johns Manville is an American corporation based in Denver, Colorado that manufactures insulation, roofing materials, and engineered products.For much of the 20th century, the then-titled Johns-Manville Corporation was the global leader in the manufacture of asbestos-containing products, including asbestos pipe insulation, asbestos shingles, asbestos roofing materials and asbestos cement pipe.
Fire resistant and non-combustible (see specification compliance). Sound Control: reduces transmission of sound through exterior and interior walls and floor or ceiling assemblies. Formaldehyde-free: will not off-gas formaldehyde in the indoor environment. The fibreglass batts are made to fit standard spacing and thickness of wood frame or steel stud construction in residential, commercial, institutional, and industrial construction. Used in conjunction with the caulking of joints and resilient channels for drywall attachment, insulation can increase STC ratings by 8 to 10 points. In floor/ceiling assemblies, sound control batts may also help reduce transmission of impact-generated sounds between adjacent areas. Sound-SHIELD batts help provide a more comfortable interior environment by reducing transmission of conversations and the sounds of televisions, stereos and ventilation systems. interior 2 x 4 wood stud wallsĢ4" on center 8 ft.JM Sound-SHIELD Formaldehyde-free batts are lightweight, sound-absorbent insulation made of long, resilient glass fibres bonded with a thermosetting resin. exterior 2 x 6 wood stud wallsġ6" on center 8 ft. interior or exterior 2 x 4 wood stud wallsġ6" on center 8 ft.

If it takes more than one batt to fill the height of a wall cavity, make sure the two pieces are butted snugly together.ġ6" on center 8 ft. Compression changes the R-value of the insulation.ħ. For shorter spaces, cut the insulation to fit properly. Always cut on the unfaced side of the batt.Ħ. Cut insulation about an inch wider than the space using a sharp utility knife against a safe backstop, such as an unfinished floor or other smooth, flat surface. Space the fasteners at least six inches from each end of the batt and 12" - 24" apart.ĥ. Secure floor insulation with wire fasteners, sometimes called "lightning rods." Press the fasteners so they bow up gently against the subflooring without compressing it. Allow friction to hold the batts in place.Ĥ.

Then, fluff it to its full expansion by pulling it forward to fill the depth of the cavity. Gently push batts into the cavity so that it sits all the way in, especially at the corner and edges.
The insulation will quickly expand to its full volume when the bag is opened.Ģ. Open the packages by cutting lengthwise through the side panel. Unfaced batts are installed between framing members but not attached, allowing friction to hold them in place.ġ. In exterior walls R-13 to R-21 is commonly used, while in interior walls where insulation is used for sound control, R-11-13 is used most frequently. For ceiling and attic spaces, use batts of R-30 or R-38. Batt insulation is made to fit within most regular wall framing, which are usually spaced 12", 16", or 24" on center, and for either 8-ft. Johns Manville Unfaced Batts Installationīatts are pre-cut panels of insulation and are available in a variety of lengths, widths and R-values. See Flash demo for product images and multimedia.
