What is the perimeter in inches using the conversion factor of 2.54 cm?
25.4 cm = 10 inches
How many is 4 by 6 inches in cm?
4 by 6 inches = 24 inches = 60.96 cm.This is not the same as 4 inches x 6 inches, which is a measure of area and, therefore, has a different conversion factor.
How much is 6.1 feet in cm?
The conversion factor is 1 inch = 2.5 cm So first you would need to convert the feet with which you are beginning into inches. There are 12 inches in a foot, so multiply 6.1 feet by 12 inches which will give you 73.2 inches. Then multiply 73.2 inches by 2.5 cm (see conversion factor above) which gives you 183 centimeters.
What is the scale factor of the scale 1 inch equals 6 inches?
6
What is the scale factor if the scale is 8 inches equals 1 foot?
2:3
10 of fiberglass insulation provide how many R?
10 inches corresponds to about R-38.
What is the r value of 8 inches of fiberglass insulation?
technically unfaced fiberglass insulation has an r value of 21 for 6 inches but that's if its perfectly installed, no gaps, no crushes, no air moving through it, no moisture, and its completely in contact with the interior heated surface. Since its unfaced, we assume it will have moisture and air moving through it and an average installation, it's likely R-13 or less.
How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch
If attic has five-inches of loose-fill fiberglass . how many inchea of TAP insulation shouldbe added to obtain an R-38?
In the U K 250 millimeters /10 inches is the required limit so if you 5 inches just now you will have to add 5 inches on top the nearest size to that is 150 mm/ 6 inches
What value does 10 insulation give?
If you are referring to the R value of insulation, then 10 would be the 'thermal resistance' value of the insulation. A value of 10 is about what 3 1/2 inches of fiberglass batt insulation would give you. That is what you might put within your exterior walls if you are using wood studs. The higher the R value the better insulation you will have. When you add up all of the R values of the materials that make up your exterior wall you will get your total value. Depending on where your building is located, and the climate in that area, you will need to adjust your insulation accordingly.
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.
What is the recommended insulation thicknesses and densities for rigid polyurethane insulation for hot water piping application?
A contractor build two houses with 2 by 6 walls. He sprayed 1.5 inches of foam into the walls of one house and used standard fiberglass insulation for the other house. The house with polyurethane insulation always had lower electric bills. They believe this is do to the fact that the foam is the worlds best insulation and it seals all air leaks.
How many inches of ISO insulation board is required on a flat roof?
12 inches
What is the conversion factor from 700c wheels to inches?
The conversion factor from 700c wheels to inches is approximately 27.56 inches.
Why is rockwool insulation used?
Rock wool or mineral wool is a more compacted less friable type of molten silica (glass) wool for use as insulation it usually comes in boards or sheets of insulation from 1 to 6 inches thick. It is fairly stiff but slightly bendable it is easy to cut and shape and can be nailed or tacked into place. The heat rating and melting temperatures of rock wool are higher than fiberglass. It is usually used in industrial settings for kilns, industrial boilers, ovens and furnaces.
How thick is R's 38 insulation?
From everything I have seen it would be about 12 inches for conventional fiber glass insulation available from Home Depot or Lowes. Polyiso insulation can give up to r-6 per inch. That equates to 7 inches for r-42.
How thick is R's insulation?
From everything I have seen it would be about 12 inches for conventional fiber glass insulation available from Home Depot or Lowes. Polyiso insulation can give up to r-6 per inch. That equates to 7 inches for r-42.
