Syndego Phase Change Materials: Insulating in the 21st Century
- Heat energy only flows from a warmer place to a cooler place.
- The amount of heat flow depends on the temperature difference and the conductivity of the heat flow path.
- Traditionally, we limit heat flow by adding more “R” Value, usually in the form of fiberglass, cellulose or foam, between the temperature differences.
- The Syndego Phase Change Material approach is totally different. It controls the temperature differential across the “R”-value.
- When temperature differences are kept low, then the heat flow across any “R”-value is also kept low.
- If the temperature difference, sometimes referred to as Delta T, equaled zero then zero heat flow would occur.
- Using the Syndego Phase Change Material approach, zero heat flow conditions have been witnessed even when large temperature differences exist.

Smarter Building Insulation
Operating costs for commercial and residential buildings are on the upswing. Rising energy costs, poor construction practices and a fundamental misunderstanding of insulating, are the primary reasons. Syndego’s Solution is a combination of Phase Change Materials (PCM’s) and traditional “R” Value. This combination is proven to save up to 50% in total energy costs related to heating, cooling, and ventilation, and can have a positive return on the investment beginning the 1st month!
By removing the heat above the indoor set point, PCM’s dramatically reduces the AC loading on the structure. Where normal wall and ceiling temperatures might be 90 or even 100 degrees in summer, it will be limited to the melt point of the PCM’s chosen, making the building much more comfortable and reducing the AC loading from what could be a 25 degree delta T (thermostat set at 75 and 100 radiating through the ceiling) to 5 degrees or less!
The object is to choose your PCM melt point just above the ideal temperature for your application (such as your thermostat set point) The difference then between the desired temperature and the PCM melt point (sometimes called Delta T) is reduced to as close to zero as possible
What are PCMs and why do we use them?
Phase Change Materials (PCM’s) do a strange and amazing thing. They do not change temperature during the change of phase from a solid to a liquid or vice versa. Water is a common Phase Change Material (PCM). Water has the ability to hold one BTU of heat energy per pound per degree F. Water in the solid phase (ICE) also has the same ability to hold one BTU of heat energy per pound per degree F.
The strange and wonderful thing is that during the phase change from liquid to solid, water gives up 144 BTUs before it can pass from 32°F liquid to 31°F ice. This is 143 times the amount of BTUs it takes to change the temperature of water or ice by one degree F at other than 32°F temperatures. It works the same in the other direction from a solid phase melting into the liquid phase. This massive amount of heat storage capacity only occurs at 32° F and is called “Latent Heat Capacity”. Unlike Sensible Heat, Latent Heat does not cause a change in temperature of the substance.
Sensible and Latent Heat
Sensible Heat is ordinary heat and it determines the temperature of a material. If you add thermal energy the temperature increases, if you remove the thermal energy the temperature falls.
Latent Heat is harder to understand. It is the heat that is released when a PCM changes phase from a liquid to a solid. To melt the PCM and change it back to a liquid requires the same amount of extra Latent Heat energy. The total amount of energy required varies with different PCM’s. In the case of water/ice it is 143 times as much to Phase Change than to raise the temperature outside of the phase change temperature range. This means a small amount of PCM at the phase change temperature can control a relatively large amount of heat energy.
The temperature difference across the internal “R” Value of a wall or a ceiling has never been challenged and was long thought to be immutable.
However, by using Phase Change Materials (PCM’s) it is possible to control this temperature difference for a time. The length of the time period is determined by the amount of PCM, the temperature difference, and the “R” Values on both sides of the PCM. A small amount of PCM to control the temperature difference across a wall for 24 hours is all that is necessary. During daylight hours the PCM is melting and each night it will refreeze. The PCM changes to solid at night and to liquid during the day. THE PCM REMAINS AT A CONSTANT TEMPERATURE! And the interior of the wall space stays at or near the Phase Change Temperature.
