The installation process for dry cellulose insulation looks like this: There are a number of advantages to using cellulose insulation over other types: There are also a few drawbacks to cellulose insulation: With cellulose, eco-friendliness is a debatable issue. It is pulverized into a fine powder that adheres and remains a part of the insulation. It is mechanically blown into or onto empty spaces in the structural part of a house to slow down the transmission of heat or cold. Temperatures in living spaces are warmer than the unconditioned attic, therefore rising heat transfers out of rooms through the ceiling. Get daily tips and tricks for making your best home. With closed walls, you have few other choices but to blow in insulation. While settling is one of blown-in cellulose insulation's advantages, this can also be a problem, mostly with walls. The most common types of insulation are fibreglass, cellulose and foam. It can be used by itself to fill in joist cavities that have no insulation or laid as a thick layer over the top of existing batts of fiberglass insulation. Loose-fill cellulose is relatively inexpensive, yet still has an R-value of about 3.5 per inch of thickness, compared to fiberglass' R-value between R3 to R4 per inch. SOPRA-CELLULOSE Calculator Use the appropriate calculation tool below depending on the type of application to determine how many bags of thermal insulating cellulose you will need to perform your insulation … Click the button to calculate the approximate R-value for this job.

The total R-value of installed insulation is calculated by multiplying its baseline R-value times the depth of the insulation in inches. Unlike fiberglass insulation installed in roll-out batts on the attic floor, cellulose is blown into the attic under air pressure through large diameter hoses. But with enclosed walls, blowing in loose-fill cellulose insulation is still by far the most practical and cost-effective method. Our current demonstration house will be a pre-fab wall system insulated with cellulose. To evaluate sprayed or blown-in types of insulation, measure the depth of the insulation and check for gaps in coverage. In addition, inspect insulation for a tight fit around building components that penetrate the insulation, such as electrical boxes. Contrary to popular belief, insulation has minimal effect on the movement of air between spaces and is of little value to seal air leaks in the house that also allow heat energy in or out. Class I refers to ordinary combustibles such as wood and paper, as opposed to Class II combustibles, such as flammable liquids, grease, gasoline, oil, etc. Loose-fill cellulose is relatively inexpensive, yet still has an, When walls are already finished, injecting loose-fill cellulose insulation is one of the few ways of adding insulation. So the green advantage of cellulose insulation may be less significant than it is sometimes portrayed. These pockets become thermal bridges, which transmit heat or cold into the house. 25 – 50 years. Blown and batt insulation have different r-values based on depth. Dense-packed cellulose insulation in double stud walls offers high performance while maintaining a low carbon footprint. Fibreglass is perhaps the most common product available in the market for insulation outpacing its close competitor cellulose by 50-1. Here, the traditional favorite is blow-in cellulose insulation, although spray-in foam is becoming steadily more common. A Princeton University study shows, a group of homes with blown in cellulose insulation in the walls had an average of 24.5% reduction of air infiltration compared to fiberglass insulation, with only the walls insulated. It’s fairly common for cold-climate builders to install a very thick layer of cellulose on an attic floor (that is, above the drywall ceiling of the floor below). Cellulose insulation with density of 1.6 pcf, 51/2 inches thick was used. – Is it o.k to use 3″ thick cellulose insulation in 6″ or 8″ metal stud wall? Not only does the cellulose remain unaffected even while the penny begins to melt, but the insulating value of the cellulose is such that no heat is felt by the hand holding the experiment. With open walls, you can install fiberglass roll insulation, although spray-applied foam insulation is also possible. As a demonstration of cellulose insulation's fire-retarding capacity, it is possible to use a blowtorch to warp a penny resting on a bed of cellulose insulation held in your hand. On the one hand, it can be considered green because it uses up to 85 percent recycled materials. Along the way, Gus earned a Bachelor of Arts in communications. We are not filling cavity to reduce cost and reduce R value inside cavity to locate condensing point outside of metal stud. Cellulose insulation offers the greatest energy savings, the highest recycled content and the lowest embodied energy of any insulation product. Shop GreenFiber Cellulose Blown-In Insulation at Lowe's Canada online store. Annual savings from cellulose insulation is dependent on many factors, including: insulation thickness, local climate, heating and cooling use, original wall performance, and more. However, during manufacturing, cellulose insulation is treated with borates, which are Class I fire retardants. The Department of Energy publishes current recommendations for the total R-value of residential insulation according to the location of the home on the DOE climate zone map. Insulation is rated by its R-value. Efficient and environmentally friendly, SOPRA-CELLULOSE AB reduces energy consumption and improves indoor comfort in a … No pressure is placed on the cellulose; it is allowed to settle over time. Cellulose insulation has a baseline R-value of 3.8 per inch. Fiberglass insulation: 21 sq. Cellulose is not unusual in this regard. These types of insulation are available in a number of different forms depending on the location and R-value you intend to add. Moisture dramatically cuts R-value and may lead to the formation of mold and mildew. Many green builders aim for a ceiling rated at R-60, R-70, or even R-100. In most homes, attics are unconditioned zones of acute temperatures that act, depending on the season, as either a heat source or a heat sink. Second, when. The properties of insulation simply slow down the transfer of energy through solid materials to prevent heat gain or loss at a rate that offsets the effect of your air conditioner or furnace. The cellulose product Home Comfort Insulation uses is treated with 100% Borate Fire Retardant Formula. Settling in attics is less problematic for two reasons. It can come from any plant-based material such as wood or sisal, but commercial cellulose insulation comes primarily from recycled paper, which is why it is regarded as eco-friendly. This heat conducts down through your ceiling and into cooler rooms below, causing your air conditioner to run longer to meet thermostat settings, increasing utility costs. With an attic, this type of insulation is just one option along with the other popular alternatives, fiberglass batts or blown-in fiberglass. This is slightly different from another type of cellulose insulation, which is designed to be blown onto open walls, much like spray foam. Durability. The most common type that homeowners will encounter is called loose-fill cellulose insulation. ft. of R-14 wall per cu. Cellulose insulation is blown by trained personnel into walls and ceilings using a pressurized installation system which ensures complete filling of cavities to the correct density. For loose-fill cellulose, this translates to a total depth ranging from 8 inches up to 16 inches. Weathershield is a cellulose insulation product made from cellulose fibre, a processed paper material treated with harmless, naturally-occurring chemicals. It seems that cavity wall should be filled with cellulose insulation on your instruction. Over time, the insulation can pack down and form pockets above the settled areas. Spray Foam Insulation. In comparison, an inch of blown fiberglass insulation has an R-value of 3.1 - 3.4 and an inch of blown cellulose in an attic has an R-value of 3.2 - 3.7. By today’s standards, most homes built more than 10 years ago can be considered under-insulated. Cellulose insulation is a clumpy, thick, and dense material that will cover up the empty places in your attic to slow down the movement of air in and out of your living space via the ceiling. An R-38 fiberglass batt should be approximately 12 inches thick, while the thickness of cellulose insulation of a finished, fitted product will larger. The mounds of loose material fill every odd-sized nook and cranny in the attic floor, thus providing better coverage than fiberglass batts. Cellulose insulation's source paper in its raw state is combustible. Studies comparing Blown in cellulose insulation Vs fiberglass insulation show that cellulose insulation was 38% tighter and required 26% less energy. Cellulose insulation technically can come from any cellular plant source, such as corncobs or sisal. Resilient channels of 24-gauge galvanized steel placed 16 inches on center and attached to … Find Blown-In Insulation at lowest price guarantee. This calculator is to be used as an estimating tool ONLY. Video: Fire Resistant Properties of Cellulose Insulation Fortunately, attic insulation can be upgraded simply by adding more to achieve the recommended total depth in inches, without removing existing insulation.

Cellulose insulation is not new to the contruction industry, loose-blown cellulose has long been used as attic insulation, and Dense-packed cellulose insulation is an excellent way to insulate walls. Cellulose insulation is not only the right choice but a performance choice. The paper used in Weathershield is 100% recycled material and the finished product contains extremely low volatile organic compounds (VOC). The Spruce uses cookies to provide you with a great user experience. R-3.7 up to R-6.5. Heat energy naturally moves from a warm zone to a cooler zone. Cellulose attains an R-38 rating with approximately 10-inches of thickness, whereas fiberglass needs be about 12-inches thick to achieve the same performance, this makes cellulose far more effective per inch. Having the correct amount of attic insulation can help you maintain a comfortable temperature throughout your home and help save money on your energy bills*—plus, prevent major issues like ice dams in the winter. In attics, Cellulose insulation stands up reasonably well against insects and vermin because it is treated with borates. Cellulose Insulation. However, because of obstructions such as wires (and just because of its sheer ease), cellulose insulation is often blown into attics, as well. When cellulose soaks up moisture in enclosed areas, it can take a long time to dry out. Insulation R-values vary based on the type, thickness and density of the insulation material. Cellulose is made from reconstituted wood fiber product, which includes newspaper, cardboard and other wood related products. Also Know, what is the R value of 12 inches of blown insulation? Input depth of existing blown-in insulation (in inches). His articles have appeared in major print outlets such as "Popular Mechanics" and "Invention & Technology." 80 – 100 years. The simple, cost-effective alternative to spray foam. Here we bust some of the unfortunate myths and misunderstandings surrounding this type of wall construction. R-Value (per inch of Thickness) R-2.2 up to R-4.3. Insulation works by retarding the flow of heat energy moving through walls and ceilings by conduction or radiation. Cellulose Insulation Manufacturers Association of Canada Page 5 of 22 General Installation Guidelines for Cellulose Fibre Insulation (CFI) MAY 2009 isolate heat sources in attics, it is important to ensure that its height exceeds the intended thickness of insulation to be applied. Reduce of energy bills (by) 20%. R-3.1 up to R-3.7. Cellulose generally retards heat transfer slightly more efficiently but is associated with higher installation costs. However, the remaining 15 percent, which includes the borate treatment, is less-than-green because it is a chemical treatment. Loose-fill cellulose insulation can settle around and conform to most of the obstructions found in walls and attics. SOPRA-CELLULOSE AB is a thermal and acoustic cellulose insulation made of 85% recycled newspaper and used in interior and exterior walls, attics, floors, and ceilings. Typically, a higher insulation R rating means better climate control and better energy efficiency for your home.
