Home Improvements - Riverside Blown Insulation Increase the ...

In order to increase the energy efficiency, the blown insulation would be the best option to consider.

Riverside blown insulation is a loose-fill insulating material, typically fiberglass, rock wool, or cellulose. The insulation material is blown under pneumatic pressure into the spaces between joists and wall studs in an existing structure. Water vapor retarders are applied first and are available in the form of a moisture-resistant, spray-on paint. Blown-in insulation is most commonly used to insulate interior walls, especially in existing buildings. Blown insulation also can be used in new construction, but the wall cavities first must be covered with temporary containment sheeting to hold insulation in place. The insulation is then blown into the wall cavities, and the studs are covered with the appropriate finishing material.

For increasing the home's energy efficiency, increasing the R-value of insulation in the attic can be done with cither batting or blown-in insulation, and several materials are available for each method. Professional equipment is required to blow insulation into place. The homeowner can install batts or hire a commercial contractor for the work to be done. Blown fiberglass insulation could be blown into place over a layer of originally installed loose insulation. Either batts or blown insulation will deliver excellent results, but both require careful installation to perform well. Both types depend on their ability to trap and hold little pockets of air so that warm or cold air cannot pass through the insulation. Blown- in insulation creates a flawless blanket in an attic or within wall cavities. Careful installation is required to attain this similar outcome with batts.

Before deciding which insulation method to use, compare the cost. The cost of fiberglass insulation blown in by professionals could cost about 0.40 dollars per square foot. Fiberglass batts cost about 0.45 dollars per square foot for the material alone. Installation costs will be in addition to that. The homeowner will only save money by using batts and doing the work oneself if one can find fiberglass batts intensely discounted. When working with fiberglass or other batt insulation, wear a respirator in order to reduce throat irritation from particles and to prevent insulation particles from being inhaled into the lungs. Gloves, a long-sleeved shirt, and goggles are also recommended. If the existing insulation is batts placed between the ceiling joists, install the new batts across the joists at a right angle to the existing element. This would assist to cover any holes in the original installation. Don't worry if the original Riverside blown insulation has settled and doesn't come up to the tops of the joists. Lay the new insulation across the joists and leave an air space between the old and new insulation. It won't affect the R-value of either one.
