Loose fill insulation is a popular choice for older homes and newer structures alike. Composed primarily of recycled newsprint and cellulose laced with pest and fire retardants, this kind of insulation is also environmentally friendly. Homeowners who are interested in boosting their home's R value can work with trustworthy Somerset County roofers to have the underside of the roof, attic ceilings and walls thoroughly insulated with this environmentally friendly material.

Blown in insulation is installed with the use of large, pressurized sprayers. This equipment uses electricity and a pressure gradient to push tiny bits of insulation into the cavities of a wall. To get these little pieces to stay along the underside of the roof, many roofers first put up gypsum boards or drywall, leave an opening for the sprayer's nozzle and then spray the insulation into the newly created wall cavity. This process makes loose fill an ideal type of insulation if the attic is going to be finished. No surfaces need to be laid over loose fill that is applied to an attic's floor. If the homeowner does intend to use the space, most will choose a material that does not take up as much room, such as foam core boards.

After the loose cellulose insulation is installed, some natural settling will occur.

The roofers from Peter W Smith Construction of Somerset County NJ would be happy to answer any question you have about residential roofing or roof repair.

Natural settling is just the process of the individual cellulose fibers coming together through the effects of gravity. It is a normal occurrence and does not suggest any errors or mistakes in the installation. If 16 inches of loose fill were blown into place to create an R value of 60, natural settlement of the material may cause the finished result to only be 14 inches in height. If more compression takes place, property owners should contact the roofers or installers, as the attic could have a ventilation issue or the ratio of pressurized air to cellulose fibers may have been incorrectly calculated when the loose fill was installed.

Achieving the U.S. Department of Energy's recommended thermal resistance value is the goal for installing this type of ventilation in a home. There is no need to surpass that recommendation. If installers put in too much insulation, it could cause problems with air flow and boost the attic's humidity level, which could cause the roof's wooden support structure to deteriorate. The loose fill must also be kept at least 3 inches away from any furnace flues, chimneys and vent openings. None of the insulation should be blown in around electrical wires or panels.
