Cellulose Insulation

All Around Roofing: Honest Roofers Denver

Homeowners who decide to make their home more energy efficient might consider improving the insulating properties of the structure. One method of doing so involves adding insulation in the walls, floors, ceilings, attic or roof. There are a few types of insulation that can improve the insulating properties of these areas, but many Denver roofing and home improvement contractors suggest loose fill or blown in insulation with cellulose. Before going along with this suggestion, however, homeowners may want to consider all their options.

Most contractors recommend loose fill and blown in insulation types for existing constructions. These products are ideal for hard to reach areas. This is because it’s easy to install and conforms to open spaces without damaging the finishes or structures. Contractors typically install this type of insulation by pouring it in or using special equipment that blows it in.

Although mineral wool and fiberglass are materials that can be used for loose fill and blown in insulation, cellulose is a more popular option. This material is derived from recycled paper products, mainly newspaper. Due to this, cellulose typically consists of 82 to 85 percent of recycled material.

First, the paper is shredded into small pieces and fiberized. This creates not only a product that is environmentally friendly, but also insulation that can be packed tightly into open spaces, inhibit airflow and deliver moderate thermal resistance at R 3.

2 to R 3.8 per inch. In addition to having excellent insulating properties, cellulose does well to prevent the transfer of sound through walls. To provide insect and fire resistance, cellulose manufacturers add mineral borate or ammonium sulfate, the latter of which costs less. Compared with other insulation materials, numerous testing shows that cellulose insulation offers superior performance at preventing fires from spreading in homes. Other types of insulation can pose a threat to the property by acting as fire hazards, on the other hand.

The installation process for existing walls involves removing a strip of siding from the exterior of the house and drilling a three inch hole into each stud bay through the sheathing. Contractors will insert special filler tubes and blow in the cellulose insulation until it reaches a density of about 3.5 pounds per cubic foot. At this density, the material does not settle in the wall cavity. The contractors finish the job by sealing the holes with plugs and replacing the strip of siding. A moisture barrier is typically not necessary.
