High Thermal Mass Building
What is thermal mass? And why is thermal mass an important thing to consider when building an energy efficient, environmentally friendly home?
Your Home, a green home building website developed by the Australian government, defines thermal mass as “the ability of a material to absorb and store heat energy.” If a material takes a lot of energy to heat up and cool off (like bricks and other types of masonry), it is said to have high thermal mass. On the other hand, if a material does not require much energy to go from hot to cold (like wood), it has low thermal mass.
If done correctly, thermal mass is an important principle in green building because it can help you increase your home’s energy efficiency and lower your energy bills. Products with high thermal mass absorb and release heat slowly, which is actually to your advantage. On cold days, you have a steady supply of warmth radiating into your home over a long period of time. On hot days, the building heats up really slowly and gradually dissipates that heat once it begins to cool off outdoors.
Faswall and thermal mass explained
Benefits of High Thermal Mass (plus High R-Value)
Easier & Cheaper to Heat & Cool
Insulation inserts within the Faswall® wall construction materials insulate the thermal mass into the living space. This harnesses the full benefit of a “thermal flywheel effect,” meaning that the wall construction material absorbs heat from the atmosphere in warm weather and releases it during cooler periods. Faswall® has lower temperature swings as compared to foam insulated concrete forms, which isolate the mass from the living space
Choose your Insulation
About Basement Insulation and why Faswall is a top choice for high R Value walls and Basements.
Faswall green building blocks are made with a natural insulation made of a mineralized wood product, which gives it a high thermal mass. Each block comes with an insulating insert, and once stacked, builders pour a pea gravel concrete aggregate mix down two cores in the center of each block. This makes the building’s thermal mass even higher. The end result is a home, office, or commercial center that will keep you cozy warm in the winter and nice and cool in the summer. The fact that Faswall green building blocks are made with recycled materials is an added benefit for people interested in green, environmentally friendly homes.
“We did a lot of research on various green building systems but settled on Faswall. Not only did it seem like the “greenest” technology, but the ease of building compared to other systems seemed like a good choice for an owner/builder. What we didn’t expect, but were totally delighted with, was how knowledgable and helpful the people at Faswall were. We couldn’t have done it without you!”
