The construction industry is changing and future

homeowners are looking for the most cost effective and

energy efficient ways to build new homes. While builders

are trying to insulate the home envelope better, using

windows that dont lose heat and creating barriers to

heating/cooling loss, there has been no breakthrough in

the capacity to store heat within the building itself until

now.

Thermal mass is a term used to describe the ability of

building materials to store heat, or thermal storagecapacity. The basic characteristic of materials with thermal

mass is their ability to absorb heat, store it, and at a later

time, release it.

Thermal Mass

In winter, thermal mass can store the heat from the sun or aheating source to release it at night, helping the home staywarm.

Appropriate use of thermal mass throughout your home can

make a big difference in comfort and to heating and cooling

bills.

Thermal Mass

Thermal mass acts as a storage unit, absorbing hot air in thesummer to keep the house cooler and more comfortable.

Building materials that are heavyweight store a lot of

heat so are said to have high thermal mass. Materials

that are lightweight do not store much heat and have

low thermal mass. Most residential construction today is

built using light-weight materials.

The use of heavyweight construction materials with high

thermal mass, i.e., concrete slab floors and

EnergyBlock walls, can reduce total heating and cooling

energy requirements by up to 35% compared to a home

built of lightweight construction materials with a low

thermal mass.

For maximum effectiveness, thermal mass should be

left exposed internally allowing it to interact with the

buildings interior. For this reason, Insulating Concrete

Forms (ICF) offer little thermal mass benefit.

Insulation must be on the exterior surface only.

External Insulation

SunTerra EnergyBlock is a

patented new system poised

to take advantage of high

thermal mass with exterior

insulation. This new systemis made up of a specially

designed concrete block with

dovetail grooves and a

masonry-insulation

connector strip to retain rigid

foam insulation, making it

ready to attach your choice

of siding.

SunTerra EnergyBlock exceeds the International

Energy Conservation Code (IECC) insulationrequirements for wood and ICF walls with comparable

insulation Rvalue in all climate zones.

SunTerra EnergyBlock allows architects, builders andhomeowners to design and construct a home with a

versatile look that can either feature the aesthetic

masonry interior surfaces or conceal them for a

traditional plaster wall appearance. EnergyBlock comes

in multiple colors and finishes.
