SIPs and Heat Transfer

SIPs and Heat Transfer | Energy Performance Building System

New Sage Homes starts with the top energy performance building system available – structural insulated panels with a polyurethane core or Sips for short. This is important to providing the best thermal barrier between the inside living area and outside elements of a building. Other forms of insulation, such as fiber-glass, cellulose, Icynene, and blue-jean material, have half the R-value, allow air-flow, and do not eliminate any of the six mechanisms of heat transfer.

Smart Green Building Strategy

Another significant factor in reducing heat transfer and increased performance is the amount of area of the building that is exposed to the elements. Buildings should be designed to create the most floor-space with the least amount of building materials, thus the least wall area. A circular building is most efficient, with an “efficiency ratio” of floor area to lineal feet of walls of 8.9. However, a circular building is more difficult to build than one with flat surfaces. An octagonal building, which has an efficiency ratio of 8.7, is much easier to build. A square building with a ratio of 7.9 is still very efficient. The more compact the design the better the performance. That is why using our energy performance building system reflects this smart green building strategy.
