is there a way to tile over plywood on a bathroom floor?
You would be better of removing the plywood floor completely - and tiling over the original surface.
What is the r value of plywood?
¼-inch plywood 0.31 3/8 inch plywood 0.47 ½-inch plywood 0.62 5/8 inch plywood 0.78 This is taken from http://www.sizes.com/units/rvalue.htm, which also has some other materials that could/would commonly be used alongside with plywood to increase the R Value such as building paper and insulation... if both sides of the frame are ply then you must also include the void.
What has infinite length but width no thickness and no endpoints?
This would be a line, which has no width, no thickness and no endpoints, but has infinite length.
What two instruments would you use to measure the diameter and thickness of a material?
Micrometer and Vernier
How thick is the standard floor and sub floor of pier and beam house?
It would usually be 1 1/8" plywood or 2 x 6 tongue and groove boards which would be 1 1/2".
What units would you measure the thickness of a glass pane?
Millimetres
What would be a good material for insulating electrical wire for safety purposes?
It really depends on what gauge (Thickness) of wire were talking about, but plastic and rubber are the most common ones.
What is the standard floor thickness?
I think you mean sub-floor. There are a few standards. 3/4 plywood or osb. 1 1/8 Plywood. 2 x 6 tounge and groove pine. Each has its advantages. I would consider the 1 1/8 T&G plywood to be the minimum standard.
Does electricity pass through camera lens?
Assuming the lens of the camera is made of glass, the answer is no. Glass is a very good insulator and it would an extremely large current (along the order of lightning) to overcome the insulating properties inherent in glass.
What unit would you use to measure the thickness of a cup Why?
Thickness is measured in units of length. You'd have to choose the one that gives a reasonable number corresponding to whatever you're measuring the thickness of. If it's the thickness of a hair, you'd probably select a sub-multiple of a meter. If it's the thickness of the atmosphere, you might select the kilometer. If it's the thickness of country gravy, that's a whole different story.
What is the unit measurement of plywood?
The answer depends on what characteristic you wish to measure: its length, width, thickness, density, rigidity, etc.The answer depends on what characteristic you wish to measure: its length, width, thickness, density, rigidity, etc.The answer depends on what characteristic you wish to measure: its length, width, thickness, density, rigidity, etc.The answer depends on what characteristic you wish to measure: its length, width, thickness, density, rigidity, etc.
4' x 8' x 18mm thick plywood weight?
It depends on the density of the plywood. This site shows some plywood densities in kg/m^3. Let's say your plywood is 500 kg/m^3 (which is at the low end of the plywood densities isted on that page). Converting the dimensions of the plywood to meters gives the following: height: 4 ft = 4 ft * (12 in/ft) * (2.54 cm/in) * (1m/100cm) = 1.22 m width: 8 ft = 8 ft * (12 in/ft) * (2.54 cm/in) * (1m/100cm) = 2.44 m thickness: 18 mm * (1m/1000mm) = .018 m The volume of the plywood is height * weight * thickness = 1.22 * 2.44 * .018 = .0535 m^3. Weight is density * volume. So, at 500 kg/m^3, the plywood would weigh: 500*.0535 = 26.8 kg. 1 kg is approximately 2.2 pounds, so 26.8 kg is 26.8 kg * (2.2 lb/kg) = 58.9 pounds. If, however for example, your plywood is 700 kg/m^3, it would weigh 40% more, or 82.5 pounds.
What temperature would plywood combust?
There is no definite temperature that plywood would combust at. Since plywood contains various chemicals, it will depend on what type those are, its size, etc.
What distance does light travel in glass during the time that it travels 1.0 meters in vacuum?
That would depend on the density, thickness and composition of the glass. It's a little less, but not a whole lot less.
What is the thickness of a windowpane in millimeters?
A plane of glass would be measured in millimetres.
What is the R value of attic insulation covered with plywood decking?
Every insulation has a different R value. It ultimately is determined by which insulation you will be using. Now lets do rough estimate. 4" thick, regular fiberglass mat has R-value of 13. Assuming that plywood has the same to half the insulating value of fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that 4" mat. Roughly R-1.6 to R-0.8
Would the tight packing of more insulation such as glass wool in an enclosed space increase or decrease the insulation value?
Answer nr. 2 Contrary to the logic expressed in the first answer, packing more tightly, glass wool would insulate slightly better, According to Izi, (sales person at Golmat ltd.). Doubling the thickness of glass wool insulation will double the insulating ratio, while doubling the density will increase the insulation ratio by about 15%. Mic602 most likely decrease. most insulation materials are based on trapping air which is a great insulator, by compressing them you would be pussing the air out and reducing insulation value.
