Blown Insulation in Attics: Installation, Tips and Best Practices If you're an environmentally conscious builder, you'll want to consider installing loose-fill insulation in an attic. Loose-fill insulation is available in a few options — fiberglass, cellulose and mineral wool — all of which contain recycled materials. Fiberglass consists of almost a third of recycled glass, spun into fibers.

Symbiosis Symbiosis and endosymbiosis. A popular theory often cited in reference to the origin of intracellular organelles is the principle of endosymbiosis. This hypothesis proposes that chloroplasts and mitochondria began as freeliving aerobic prokaryotic ancestors which were engulfed by an ancient prokaryotic cell.

Attic Fan Installation When installed properly, an attic fan can effectively cool the attic and draw fresh, cool air into the home. Attic fans work by drawing air from the rest of the house into the attic through an opening between the two spaces. It then ventilates this air to the outside of the house for an overall cooling effect.

Insulation Materials Fiberglass (or fiber glass) -- which consists of extremely fine glass fibers -- is one of the most ubiquitous insulation materials. It's commonly used in two different types of insulation: blanket (batts and rolls) and loose-fill and is also available as rigid boards and duct insulation. Manufacturers now produce medium- and high-density fiberglass batt insulation products that have slightly higher R-values than the standard batts.

The Right Way to Add More Insulation to Your Attic Fiberglass insulation usually comes with a paper moisture barrier. Always make sure the vapor barrier is facing the heated portion of your home. If this were an attic, the barrier would be on the bottom. When adding insulation, you'll first want to bring the fiberglass up to the tops of the joists. To do this, use an unfaced insulation with no paper moisture barrier. Once you're level with the joist tops, you can add more insulation by running it at right angles to the joists.

Types of Blown Insulation Materials There are three general types of blown insulation materials currently available: fiberglass, cellulose and rock wool. Fiberglass loose-fill insulation is made glass and sand that are spun or “blown” into fibers. This type of insulation is great for wall cavities and attics. It can properly insulate an area and protect it too from moisture which could lead to the formation of fungus and mildew. In this age or recycling, most manufacturers use 20% to 30% recycled glass.
