When you consider adding insulation to your house, the picture that generally comes to mind is long strips of fiberglass insulation in unfaced rolls. Batts of encountered fiberglass insulation is the standard material utilized to protect wall and joist cavities throughout new construction, and improving the insulation in attic rooms commonly involves laying a “blanket” of unfaced fiberglass rolls throughout the attic room flooring.
But fiberglass batts and rolls have constraints for retrofit applications, homeowners are wise to take into consideration blow-in insulation as a choice for boosting the house’s insulation R-value. R-value is the market standard for determining the resistance value of particular shielding products; the higher the R-value, the better the product insulates.
The term blow-in insulation (or loose-fill insulation) refers to the procedure of filling up stud or joist voids or covering attic room flooring, with any type of loosened material that has a great insulating R-value. While there are a range of products that can be made use of, including styrofoam pellets or loosened fiberglass fibers, the most common product made use of for blow-in applications is cellulose material.
Made from recycled paper, cardboard, and various other wood-based materials, blow-in cellulose is treated with boric acid and other substances that make it fire and mold-resistant. It is then packaged in securely packed bales or bags. Installation involves the use of a mechanical blower/hopper that churns up the cellulose product with paddles to loosen it as well as mix it with air, then distributes the cosy insulation with hoses to anywhere that it is required.
Blow-in insulation is commonly considered the very best way of adding insulation in existing buildings and construction, both for attic areas and also in wall cavities.
Adding insulation in an attic room can be done by carrying unfaced rolls of fiberglass insulation right into an attic and also unrolling them to create an undisturbed blanket across the attic floor, yet this can be a tiring procedure, particularly if you only have a little accessibility hatch. Blow-in insulation supplies a much faster way to dramatically improve your attic insulation. In an matter of an hour or 2, a Master Ech insulation specialist can blow a thick blanket of loosened insulation across the flooring of the attic using a single hose pipe add with the attic hatch. For wall voids, blow-in insulation is the only sensible way to boost the R-value of stud cavities, except removing entire wall surface areas to install faced fiberglass batts.
Blow-in cellulose insulation is a favorite among property owners who like green products, considering that the material is made totally from recycled paper as well as wood products, with very few artificial processes or chemicals included.
How It Is Done for Attic Spaces
When attic rooms are shielded with blow-in insulation, the setup team commonly consists of two individuals. One worker navigates around the attic with the blower hose pipe, spraying fluffed-up insulation throughout the flooring as well as right into cavities; the insulation quickly settles around any type of attic room blockages. The other employee runs the blower unit from an indoor room or outside the house, feeding bags or bales of cellulose right into the receptacle and managing the air mixture to maintain the pipes. Together, the employees will blow in a layer of insulation to a density thickness that attains the preferred R-value. Where a fiberglass blanket currently exists in the attic room, the additional blow-in insulation is usually spread out right on top of the fiberglass.
