Crushed stone has continuously been used for a variety of construction needs because of its versatility. Crushed stone uses can vary from base material for pavers and bricks to being used to dress up areas for walking and driving. When it comes to crushed stone grades, it’s categorized by the size of the stone after it has been crushed.
Polyisocyanurate Rigid Insulation. Polyisocyanurate rigid insulation (isocyanurate or iso) is the most commonly used flat roof insulation, and can be used in any type of flat roof system.Isocyanurate rigid insulation has the highest R-value of any insulation product with an R-value of 6.0 per inch.

Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color. Solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total reflectance.

Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability.A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank.Water should move in and out from the ballast tank to balance the ship.

• Permit easy removal and re-installation of the ballast and insulation for making repairs or for constructing additional stories. In addition, a protected membrane roof provides an environmentally preferred option to reuse the insulation • Allow for a range of ballast options – stone, precast paving slabs, soil and plantings
Overall R value of steel stud walls are calculated using the Modified Zone Method from ASHRAE Handbook of Fundamentals 2013 Chapter 27. Note: There is a stud spacing parameter adjustment applied for walls with high framing fractions. Other methods for calculating R value of metal studs include IECC U-Factor tables and ANSI test results.
PMR systems offer unique possibilities for recycling. Since the XEPS is both water-resistant and is protected against UV degradation by the filter fabric and ballast/pavers, it can be reused. Warranties as to retained R-value are offered even when reinstalled on a new roof installation.
Crushed stone that ranges from 1 to 2 inches in diameter is used for drainage solutions, in dry wells, in septic systems and as ballast for railroad tracks. It consists of trap rock, granite, limestone and gneiss and is used to produce cement, lime and riprap stone.
The R-value of an uninsulated, 8-inch-thick basement wall built using normal-weight concrete is 1.35, based on data from the 1993 American Society of Heating, Refrigeration, and Air-Conditioning Engineers' Handbook. By doubling the thickness of the wall to 16 inches, the R-value only increases by 0.50.

Oct 11, 2009· I can't seem to find reference values for solid stone R-values. I have a 20" basement wall- and I would like to calculate the heat loss. Unfortunately, I can't find R-values for stone, only concrete and brick. I'm not sure what kind of stone it is (or if that matters). The house is 100 years old and in the midwest. Thanks!

A material’s R-value is the measure of its resistance to heat flow. It is important to know the R-value because many states or regions require that a roof system have a minimum amount of thermal resistance on commercial, industrial, and/or institutional buildings.
Naturally the weight of stone/rock varies according to the type of rock. But, on average, one cubic foot of rock weighs in the neighborhood of 200 pounds.
