SIREWALL has more than three times the thermal resistance of an insulated 2x6 wood frame wall.
Passive solar storage in mass essentially equals free heat and consistent, even comfort.
Higher R-values and thermal mass work together to lower overall operating costs and allow much smaller heating systems.
In many cases, cooling systems can be eliminated entirely.
The highest level of thermal comfort is attained with thermal mass.
Lower energy bills save money every month.
Less expensive mechanical systems save money during construction.
Timeless distinction.
