the diffrence between fiberglass and asbestas are the lettlers firgl sence the word asbestas does not have those specific letters.
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.
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.
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.
Closed-cell foam has tightly packed, sealed cells, making it dense, rigid, and water-resistant with a higher R-value per inch. Open-cell foam has interconnected, unsealed cells, making it softer, more flexible, and breathable with better sound absorption.
difference between cro and powerscope?
The difference between the two is that an asbestos gasket uses asbestos as a reinforcing fiber while a non-asbestos gasket does not.
Several companies used asbestos in various kinds of insulation form 1950 -1985. An answer to this question, listing brand names, would be excessively long.
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.
If there is no air circulation between the insulation and the roof, it could get condensation, which ultimately could cause rotting.
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.
Energy-Miser Buildings in Omaha,NE has huge fiberglass blanket insulation between the sidewall columns.
Fiberglass shingles are lighter and thiner with there base being made out of fiberglass. The fiberglass shingles will cost more but wear better.
Lexan is a polycarbonate plastic. Fiberglass is exactly that, fibers of glass bound together with a resin.
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.
Rockwool and fiberglass are both sound insulation materials, but they have some differences. Rockwool is made from volcanic rock and is denser than fiberglass, providing better sound absorption. Fiberglass is made from glass fibers and is lighter and more flexible, making it easier to install. Rockwool is more fire-resistant than fiberglass and can withstand higher temperatures. Fiberglass is generally cheaper than rockwool but may not be as effective in blocking sound.
Hot insulation is designed to prevent heat transfer and maintain temperature in a system, while cold insulation is used to prevent condensation and maintain cooler temperatures. Hot insulation typically uses materials like fiberglass or mineral wool, while cold insulation often uses materials like foam or rubber. The choice of insulation depends on the specific temperature requirements of the system.
Rock wool is made from natural basalt rock and is denser than fiberglass insulation, making it better at soundproofing and fire resistance. Fiberglass is made from molten glass fibers and is lighter and more flexible, making it easier to handle and install. Fiberglass insulation typically has a higher R-value than rock wool, providing better thermal insulation.
