Many buildings can be easily retrofitted by simply placing our ENRG BlanketTM products into the ceiling cavity, on-top of existing ceiling tiles. You can install the product today and start seeing the energy savings tomorrow.
Unlike insulation, where a continuous barrier is required to resist thermal change, phase change materials work very effectively even if they only cover sixty to seventy percent of the ceiling area. Thus you can avoid areas with heating ducts, light fixtures, speakers, etc. This allows for rapid product installation that can be performed by the building occupants or facility maintenance technicians.
Ideal for spaces that have large internal loads from people, lights and equipment or have discomfort issues, we typically recommend our ENRG BlanketTM M27/Q25 Class C fire/Class product because of its low cost and light weight.
In new and retrofit BioPCMTM ceiling tile installations we consistently see significant savings on HVAC energy and maintenance expenditures while enhancing occupant comfort.
Metal roofing & re-roofing over existing roofs
ENRG Blanket installed in new or retrofit metal panel roofs will greatly reduce roof heat flux, cooling loads, and both cooling and heating energy use. The BioPCMTM Cool Roof technology creates significant savings in a wide range of climate zones. More information about a specific product being marketed through our Fabral PCES partnership can be found at this link.
Three experimental attics utilizing different roof retrofit technologies were constructed at the Oak Ridge National Laboratory Field Exposure Testing Facility. The first test attic represents the traditional way of roof retrofit, where the old roofing materials are totally removed for disposal in landfills, and replaced with a new roof cover. The two other installations utilized roof-over-the-roof technologies that do not require removal of the old materials.
The metal panel roofs contained a cool-roof coating to minimize solar heat gains.
In the third test attic, roof-integrated PV laminate and PCM heat sink were utilized. The test data demonstrated that roof-over-the-roof re-roofing can be a very effective way of not only refurbishing the old aged roofing surface, but also improving energy performance. Over the winter and spring, the PV-PCM attic showed a 30% reduction in heating load compared to the conventional shingle attic. On average, the maximum day time temperatures were lower by about 15% in the PV-PCM attic compared to the shingle attic. This difference was even higher in the late-spring and summer months.

BioPCMTM Stud Walls
The most common means of installation in new construction is to secure the ENRG BlanketTM to the studs of the wall placing it between the insulation and the wallboard.
Recommended ENRG BlanketTM M values per orientation (Northern Hemisphere):
- South - M51
- West - M51
- East - M27
- North - M 27 (or No PCM in moderate climates)
These recommendations are based on modeling and account for the effects of solar radiation on building envelopes. For spaces with large internal gains, north orientations may be useful, however north orientations are recommended only when other orientations are not available. BioPCMTM wall applications are generally recommended after BioPCMTM roof applications because roof applications tend to provide greater benefits.
ENRG BlanketTM goes beyond insulation by providing thermal energy storage at the source of the load, greatly reducing wall heat flux entering a building. Storing daytime solar loads for nighttime usage allows your building to recycle energy. This cycling of thermal energy reduces HVAC system run-time, maintenance, size requirement and energy consumption while enhancing human comfort.
