The process of manufacturing fiberglass insulation gives it the ability to resist heat flow. First, a mixture is prepared with the proper amount of raw ingredients and melted at a temperature of 2500 degrees F. The molten glass flows from the furnace into a cylindrical container with small holes. The most common types of materials used for loose-fill insulation include cellulose, fiberglass, and mineral (rock or slag) wool. All of these materials are produced using recycled waste materials. Cellulose is primarily made from recycled newsprint. Most fiberglass products contain 40% to 60% recycled glass. Modern cellulose insulation is made from either 75 to 85 percent ground up recycled paper or recycled denim. It is heavily treated – around 15 percent by volume – with boric acid, borax or ammonium sulfate. Fiberglass. Fiberglass Insulation. Fiberglass is the most common insulation used in modern times. Mineral Wool. Mineral Wool. Mineral wool actually refers to several different types of insulation. Cellulose. Cellulose Insulation Material. Polyurethane Foam. Polyurethane Insulation. Polystyrene. Polystyrene (Styrofoam). This principle is used industrially in building and piping insulation such as (glass wool), cellulose, rock wool, polystyrene foam (styrofoam), urethane foam, vermiculite, perlite, and cork. Trapping air is also the principle in all highly insulating clothing materials such as wool, down feathers and fleece.

Fiberglass, invented in 1938 by Russell Games Slayter for Owens-Corning, is the typical referent when the generic term “fiberglass” is used, and it is well known across America as the pink, fluffy material resembling cotton candy that is used as insulation in 90 percent of buildings in the country.

What Insulation is Best for Exterior Walls? Fiberglass has been used as a home insulation material for decades. It's affordable and effective, making it the go-to choice for many homebuilders and contractors. Cellulose is a great choice for insulating an enclosed existing wall with minimal demolition. Spray foam is applied wet and expands into thick, hard foam.

Cellulose. Mainly made from recycled newspaper, cellulose is arguably the granddaddy of green insulation. With an R-value similar to fiberglass (near 3. 5 per inch), cellulose-—either blown or sprayed—features the same benefits as fiberglass without the cons such as formaldehyde and potentially harmful fire retardants.

Foam board insulation is a great alternative to the very common fiberglass batt insulation that is in most of our homes. It has a higher R-Value per inch of thickness, it's resistant to moisture and is easy to work with.

A roll of insulation costs about $0. 80 to $1. 00 per square foot. The price fluctuates depending on the brand, material, thickness and R-value of the insulation.

Loose-Fill Fiberglass If you have loose-fill insulation that is white and fluffy and has a little shine, it is probably fiberglass fill. Because it is a glass product, fiberglass has a slight shine when subjected to bright light. It is very soft, almost like cotton candy, and is composed on very fine fibers.

The insulation in your attic should be at least 12" thick. The thicker the better. It is not uncommon to see 15" to 20" of insulation in a well insulated attic. If your attic insulation is only a few inches thick or if you can see the ceiling joists, you're wasting money on your heating and cooling bills.

How Fiberglass Insulation Works. Fiberglass as an insulator slows the spread of heat, cold, and sound in structures. The material does this by trapping pockets of air, keeping rooms warm in the winter and cooler in the summer, according to the International Association of Certified Home Inspectors (InterNACHI).

How Is Air an Insulator? Air is a collection of gases, and it is not a good conductor or radiator. Air is excellent at convection, but the amount of heat that can be transferred is minimal because the low mass of the substance cannot store a great deal of heat. Air is used as an insulator in coolers and building walls.

Measure the length and width of the area you need to insulate. Multiply the length times the width to determine the square footage of the space. Decide the type of insulation to use. Cellulose insulation is calculated based on the depth of the blown-in insulation.

Bubble wrap is an excellent insulator thanks to small pockets of air trapped within the bubbles. After applying bubble wrap insulation to your windowpane from the inside, tiny bubbles serve as a network of many insulating pockets filled with air.

Fiberglass batts are typically the cheapest insulation, but a loose corner or tear can diminish the insulation quality.

The fabric that proved to be the best insulator was between terry cloth and fleece. Both fabrics kept the water hot for the longest amount of time. Next was wool and then velvet. If you want to be insulated against the cold, you should wear terry cloth or fleece.

An insulating material's resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. Installing more insulation in your home increases the R-value and the resistance to heat flow.
