CIC can be used as standalone insulation on building envelopes or, perhaps ideally, in conjunction with mass-based, conventional insulation. Conventional insulation works by creating a barrier that slows heat transfer through roofs and walls. But once conventional insulation becomes saturated with heat energy, it releases that heat into the building. Conventional mass-based insulation is very useful during the winter for the purpose of holding in heat and maintaining a warm envelope of heat around your home’s walls, ceiling, and floors. However, during a warm summer, the mass becomes a heat sink, absorbing energy during the day and slowly releasing through the night. CIC Heat Block, on the other hand, works by initially reflecting a very high percentage of solar gain away from the building! It also slows the transfer of the remaining energy with low-emissivity and low-transmittance properties.
