Thermal Insulation
Energy savings in the operation of buildings are of particular importance as the cost of energy for heating and air conditioning in most cases represent the major cost factor in the operating cost of a building. The entrained air in the cellular structure of BILTEC AAC system gives the product excellent thermal insulation properties, as well as good heat retention characteristics. These characteristics contribute significantly to the energy saving performance of the building .
SLIDE 16

Fire Resistance
AAC has one of the highest hourly fire resistance ratings per millimetre of any building material. This makes it an ideal choice for fire protection around steel columns and steel beams, and in the construction of shaft walls, stairwells, corridors and firewalls. A 100mm and a 200 mm non-load bearing wall shall have fir resistance
- f 2 hours and 6 hours respectively .

Earthquake Resistance
AAC has been used for many years in areas subject to seismic action. Building which consist fully or partly of AAC have in general terms shown good resistance to earthquake forces in practice. The light weight of AAC reduces the seismic forces in common with some other materials. The non combustible and fire resistance nature of the AAC material is an advantage against fires commonly associated with earthquakes. The low weight of AAC in relation to its strength is an intrinsic advantage for earthquake design. AAC permits the designer to reduce the mass of the structure, limiting the impact of accelerations introduced in seismic situation.
