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

C = pi * 2 * r30 = 3.14159 * 2 * r30 = 6.28318 * rr = 30/6.28318r = 4.77465233 cm

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.
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.
R 13 for 3.5" wall cavities, R19 for 5.5". R30 for blown in insulation and batts in ceilings.
57% gain. A R30 would be the same as a R19 + a R11 batt.
