One of the disadvantages of modern lightweight construction is its lack of thermal mass, which means this type of building can overheat in the summer and can’t retain heat in the winter. Often, heating and cooling systems are installed to maintain temperatures within the comfort zone. However, it is also possible to replicate the effect of thermal mass of the building using phase change materials (PCM).

Thermal energy storage through PCM is capable of storing and releasing large amounts of energy. The system depends on the shift in phase of the material for holding and releasing the energy. For instance, processes such as melting, solidifying or evaporation require energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa. Therefore, PCMs readily and predictably change their phase with a certain input of energy and release this energy at a later time.

ENRG Blanket encloses a natural, non-toxic and non-corrosive phase change material, BioPCM^®, between two rugged, multi-layer films (polymer and /or aluminum). The resulting "blanket" is tear-resistant, long-lasting, and will maintain its thermal performance for over 100 years.

ENRG Blanket actively absorbs heat when room temperature exceeds the desired set point. In summer, this action delays the need for mechanical cooling. In winter, this action absorbs and stores heat that would have otherwise been lost.

ENRG Blanket releases stored heat when room temperature drops below the desired set point. In summer, the daytime heat is now moved more efficiently into cooler evening air. In winter, the stored heat is given back to the occupied space, helping maintain warmth for hours.

ENRG Blanket is easy to install above drop ceilings, behind sheet-rock, or under roofing. In both retrofit and new construction applications, installation can often be completed in a single evening, avoiding disruption to business operations.
