SunTerra EnergyBlock is a new innovative concrete block wall system that has the ability to absorb and release natural heat in a home or building providing for an even and comfortable living and/or working environment with a major reduction in heating and cooling expense.

SunTerra EnergyBlock is an 8" x 8" x 16" concrete masonry unit “CMU" that can be produced at any block manufacturer licensed to sell Sunterra EnergyBlock.

These blocks are assembled by a mason/contractor in the same manner per the same building codes as historically done, with the added benefit, to install insulation and choice of siding to the exterior or interior wall surfaces. This provides the option for choice of insulation and siding to the exterior or insulation and wallboard to the interior, creating a highly energy efficient, durable wall system.

With exterior insulation, the interior decorative wall surface produces a natural thermal battery that reacts beneficially to the living space of the building.  It absorbs heat, stores heat, and gives it back as you need it for warmth in the winter. And, it absorbs unwanted heat when you want to stay cool in the summer.
