MIRAFOAM Λ(LAMBDA) is a high-performance thermal insulation material that meets the performance requirements of the next generation. By adding special technology to MIRAFOAM we were able to achieve thermal conductivity of 0.022W/m-K, which exceeds the limit of thermal insulation performance of extruded polystyrene foam. With the growing demand for carbon neutrality and the further raising of insulation standards for houses there are high expectations for MIRAFOAM Λ.

MIRAFOAM is an extruded polystyrene foam used for thermal insulation of homes and buildings. CFC gas is not used as a foaming agent.　Its thermal conductivity is approximately 1/50 that of concrete making it an excellent energy-saving heat insulator. It also has excellent waterproofing and toughness.
MIRAFOAM can be easily cut with a saw or cutter knife, making it easy to install and work with.

JSP can provide pre-cut insulation materials if the pre-cut drawings are provided to us. This eliminates the need for processing insulation materials at the construction site, thereby reducing waste, construction period, and labor costs.

The world's only low-density foamed polycarbonate, MIRAPOLYCAFOAM combines the excellent mechanical properties of a tough engineering plastic with lightweight properties. It can be molded or composited with other materials and performs over a wide temperature range (-40°C to 120°C). It also exhibits outstanding termite resistance and is used as a heat insulator for housing foundations. It is a human- and environment-friendly product as no chemicals are used.
