It can range from R30 000 for a very small, cheap house, to R30 million or more.

The R30 Series ThinkPad was first introduced in November 2001. Someone that would interested in this specific computer should contact their local IBM dealer.

This is the process commercial insulators use. It involves a large truck mounted blower and as much as 200 feet of hose to shred and blow insulation into an attic area. If you are a do-it-your-selfer, you may want to consider R30 batts.
R30 refers to the size and shape of a reflector light bulb. It has a diameter of 3.75 inches and is often used for directional lighting in recessed cans. The "R" stands for "reflector" while "30" is a measurement in eighths of an inch for the diameter of the bulb.
The higher the R-value, the better the insulation. Therefore, a material with an R38 insulation value will have less heat loss compared to a material with an R30 insulation value since it provides greater resistance to heat flow.
R20 000-r30 000
6% of R500 000 = R500 000*6/100 = R30 000
Everything is geared tward energy conservation. A R30 attic blanket is the standard. R38 is better.
