The world of prefab and modular homes. |

Popular Science recently featured a project using a new type of prefab panel frame by 
kama Energy Efficient Building Systems.
These aren't your conventional structural insulating panels. Instead of foam and strand board, Kama...custom-makes the rigid panels out of light-gauge metal studs and a special type of expanded polystyrene called Neopor that's non-toxic, fully recyclable and blended with graphite to lock out heat, moisture and mold.
According to John B. Carnett, the Popular Science staff photographer who is building the house:
They cost me about 5 percent less than a stick frame would have, but they're 60 percent more energy-efficient and can cut heating and cooling bills in half.
The price listed in his specs for the prefab panel box installation is $7.04 per sf.
Carnett claims to be "the first in the U.S to incorporate Kama's new panels."
