Infinite R™: The #1 Phase Change Material for buildings and energy storage

A revolutionary solution that the building & energy industry has been looking for.

Global Leader in Thermal Energy Storage

We are proud to be Malaysia’s exclusive distributor for the most advanced PHASE CHANGE MATERIAL technology developed for the building industry

Green Castle Innovation is a global leader in the development and deployment of innovative energy-efficiency and thermal storage solutions that harness the power of phase change materials. There have been millions of square feet of Infinite R™ installed with proven results.

The Problem

The price of energy and peak use demand charges are near all-time highs and demand for power is on the rise. Business operators are seeking new, cost-effective technologies to reduce power use, manage operating expenses and reduce impact on the environment.

The Solution

Our suite of energy-efficiency products is powered by Infinite R™, a trademarked and proprietary phase change material. When installed within a structure, Infinite R™ actively stabilizes interior temperature, absorbing heat when temperature exceeds a desired target and releasing heat when temperature drops below that target.

The Benefits

HVAC power consumption is reduced by up to 35%, producing energy savings that rapidly pay back the installed cost of our products. Our products install quickly without business disruption and require no maintenance over their useful life of over 100 years

Infinite R™ is a phase change building material that stores energy when you don’t need it, releasing it when you do.

It works the same as ice inside a cooler, slowly melting or thawing to maintain a target temperature using the process of phase change. It drastically increases the resiliency of buildings and communities, slashes energy costs by as much as half and increases the capacity for a more comfortable world.

Using Infinite R™ for new energy capacity is equivalent to:

315 Watts

Energy Per Square Metre

18 Inches

Concrete Mass Per Square Foot


Less £ to Develop Than Solar Power


Less £ to Develop Than Biomass


Less £ to Develop Than Natural Gas

And that’s just the beginning… Infinite R™ has even greater benefits
