Thermal Insulation

Reduce heating and cooling costs – Hebel AAC is the solution.

Thermal(1)

Buildings constructed of HEBEL AAC provide substantial energy savings in both hot and cold climates. The unique closed cellular structure and the thermal mass contribute to a high R-value and air-tightness which reduce heating and cooling costs and improve indoor air quality. Buildings have seen savings on air conditioning up to 35% by using HEBEL AAC.
 

Hebel AAC has exceptional thermal insulating qualities. In summer, the heat stored in the wall during the day is returned to the outside during the hours of the night. The interior remains cool and pleasant. In winter, the phenomenon is reversed and limits the heating periods and makes significant energy savings; Hebel AAC also removes the unpleasant sensation of cold wall.


Advantages of Thermal on Hebel AAC.
  ✓Operational life time energy savings.
  ✓Ability to store heat or cold.
  ✓Great performance in R-Value
  ✓No thermal bridging
  ✓Vapor control
  ✓Comfort-indoor air quality

 

AAC Out Performs CMU (concrete blocks) and Light Frame Construction in Thermal Performance via:

 

Energy Savings
+Significantly better R-equivalent value
+Monolithic construction, tighter envelope
