How can you tell the difference between asbestos roofing or other roofing?
Check the roof for asbestos marking or the packing that it came in. If you are still trying to figure out if there is asbestos, call the manufacturer and they can give you details.
What is the difference between closed cell foam insulation and open cell foam insulation?
Closed-cell foam insulation differs from open cell foam insulation in the fact that closed-cell foam insulation has tiny foams cells that are closed and packed together. They are filled with gas that helps the foam rise. Open cell foam does not have this characteristic.
How does air insulate?
Air insulates heat transfer as well as (lower voltages of) electricity basically by just being there. Heat takes time to transfer between media. Consider a house's wall cavity without added insulation. There is a layer of drywall on the inside, followed by a layer of air, followed by a layer of wood on the outside. So for heat to travel from the inside to the outside it has to start vibrating the drywall molecules faster first (which is what we do when we heat anything up). Then it has to vibrate the molecules of air faster (and those buggers move around pretty easily). Then it has to vibrate the wood molecules faster, then the siding even. So air is just another layer that has to be passed through. The longer we make the heat take to transfer, the better insulated it is. Now add some fiberglass insulation to your house's wall cavity. Do you know that it is counterproductive to stuff as much insulation in as possible? Know why? Because air helps the insulation pass heat through more slowly! Imagine it... if there are thousands of layers of fiberglass, and air.... it's going to take that poor heat energy a while to vibrate all those molecules. But if you stuff that air space full of insulation.... the 'insulation' starts to behave like a solid chunk of fiberglass, which doesn't insulate as well as thousands of layers of fiberglass and air.
How many inches of Cellulose Insulation equals r49?
R49 is equal to 13 settled inches of cellulose insulation. If the insulation has not settled yet then it should be between 15-16" deep.

Difference between asbestos and non asbestos gasket?
The difference between the two is that an asbestos gasket uses asbestos as a reinforcing fiber while a non-asbestos gasket does not.
Which company used asbestos in their insulation between 1950 -1985 and what was the name of the insulation?
Several companies used asbestos in various kinds of insulation form 1950 -1985. An answer to this question, listing brand names, would be excessively long.
If you have fiberglass insulation in the floor of your attic what problems may you encounter if you apply additional fiberglass blanket insulation to the underside of your clear span attic roof?
If there is no air circulation between the insulation and the roof, it could get condensation, which ultimately could cause rotting.
Difference between plaster and fiberglass pools?
One of the differences between plaster and fiberglass pools is that fiberglass stays smooth. Plaster can become rough. Another difference is that unlike plaster, fiberglass does not chip, and crack.
What is the difference between a foam and fiberglass surfboard?
The main difference between a foam and a fiberglass surfboard is in their strength. Fiberglass has many layers which give it increased durability without increasing weight significantly.
What is the difference between corrugated asbestos roofing and asbestos cement flat sheet?
The difference between corrugated asbestos roofing and flat asbestos cement sheet is the form in which it was cast and, perhaps, the thickness of the finished product. Asbestos was merely an additive to cement. Both products are basically cement with a fiber strengthener that happens to be asbestos.
What is that building in Omaha, NE with the huge fiberglass columns?
Energy-Miser Buildings in Omaha,NE has huge fiberglass blanket insulation between the sidewall columns.
What is the difference between a fiberglass roof and a shingled roof?
Fiberglass shingles are lighter and thiner with there base being made out of fiberglass. The fiberglass shingles will cost more but wear better.
What is the difference between fiberglass and lexan?
Lexan is a polycarbonate plastic. Fiberglass is exactly that, fibers of glass bound together with a resin.
The Differences Between Foam Insulation Boards And Fiberglass Batting?
Fiberglass batting that comes in large rolls or strips has been one of the most widely used forms of insulation. Developments over the last two decades have introduced a much wider range of options for homeowners. One of the most popular alternatives is foam insulation board. These are thin and rigid boards made from materials like polyurethane or polystyrene. Homeowners who are installing insulation in an attic will want to understand the differences between fiberglass batting and foam insulation boards. The most noticeable difference is the thickness of the two types of insulation. Fiberglass batting can be a foot or more thick. Foam insulation board can be less than a single inch in thickness. Additionally, foam boards have a higher insulating value for the thickness than fiberglass batting. The thin boards allow homeowners to install the boards in locations where batting would be impractical or cumbersome. Foam insulation boards will last longer than fiberglass batting in an average attic. Fiberglass batting is vulnerable to moisture. Moisture in the attic will cause the fiberglass to compress over time. This reduces the amount of pockets in the batting to trap air. The result is a reduction in insulating power. The batting is also vulnerable to pests that make homes in the fibers. Foam insulation boards are more durable and more resistant to moisture and pests in the home. Fiberglass insulation contains very small particles of actual glass within the fibers. Handling and installing fiberglass insulation requires wearing gloves, respirators and other protective gear to prevent the glass from create hundreds of small cuts on the skin or even in the lungs. Foam insulation board can be handled casually. Installation is as simple as gluing or tacking the panels into place as opposed to stuffing and spreading batting. Fiberglass batting is frequently used in one area in the attic by itself. Foam insulation board can be combined with other modern types of insulation in order to increase the amount of protection in an attic. Foam insulation boards can be used with vapor barriers, radiant heat barriers and spray foams that seal small gaps along the edges. This improves the insulation in an attic without creating a complex jumble of materials.
