What are phase change materials?

Phase change materials (PCM) are substances that absorb and release large amounts of thermal energy while melting and freezing.

When freezing, they release energy as latent heat at a relatively constant temperature. When melting, heat is absorbed. PCMs recharge as they fluctuate, making them ideal for temperature control. 

Increased thermal mass delivers energy savings

When phase change materials reach the temperature at which they melt, they absorb large amounts of heat at an almost constant temperature. The PCM continues to absorb heat without a significant rise in temperature until all the material is transformed to the liquid phase. When the ambient temperature falls, the PCM solidifies and releases the stored latent heat. 

PCMs manage internal temperatures effectively and efficiently, reducing the load on HVAC systems and providing a comfortable and consistent working environment. PCMs also provide an efficient means of bulk thermal storage, reducing energy use during peak demand periods, reducing or shaving peak demand charges.

  • Increasing thermal mass Phase Change Materials are a lightweight solution for thermal mass that can be up to 9 x lighter than heavy density concrete.
  • A comfortable working temperature PCMs smooth out temperature peaks of a building resulting in an improved working environment.

Infinite R™ Phase Change Mats

Energy Savings that Pay For Your Roof

  • Reduce Energy Costs, Increase Comfort
  • Thin, Lightweight & Easy to Install
  • Store “Off-Peak” for daytime use!
  • Fast Payback: Heating & Cooling Savings

Phase Change Materials work like ice inside a cooler. As they melt, they absorb heat without changing temperature until completely melted. As they freeze, they release that heat back again.

Infinite R™ can be located within your roofing system to shield your building from hot roof temperatures in summer, while stabilizing interior heating temperatures in winter and stopping drastic temperature drops overnight during “un-occupied” cycles.

Our Advantage

Attractive Pay-Back Period
Depending on location, savings from Infinite R™ can pay back its fully-installed cost in two to five years.

No Operating Cost, Long Lifetime
Infinite R™ requires no power and no maintenance to deliver its savings.

Reduces Carbon Footprint
Reduces carbon footprint as less power is consumed
