In case of contact with water,Aerolite does not loose its physical integrity |
In case of contact with water,the ceiling starts disintegrating |
In case of contact with water,Board does not loose its physical integrity. But the painting done at the site starts peeling off |
In case of contact with water,the ceiling starts disintegrating. The PVC films if pasted, would get peeled out. |
Might result in rusting. If the perforated metal tile is backed with acoustic wool/mat, then it would emit bad smell when it comes in contact with water |

Sound Absorption (NRC) |
0.10 to 0.75 depending on product |
0.10 to 0.70 depending on product |
High density product, hence very poor Sound absorption. Perforated tiles backed with acoustic mat might have sound absorption. |
High density product, hence very poor Sound absorption. Perforated tiles backed with acoustic mat might have sound absorption. |

Thermal conductivity |
≤0.05 W/m°K |
0.052 - 0.057 W/m°K |
0.18 W/m°K - Air conditioning cost is very high (more than 3 times) in comparison to Aerolite ceiling |
0.16 W/m°K - Air Conditioning running cost is high in comparison to Aerolite Ceilings (almost three times) |
Being Metal, Thermal Conductivty is very high,hence the Air Conditioning running cost is very high |
|
Termite Resistance |
Inorganic material. Hence no termite attacks |
Organic binders used, hence prone to termite attacks |
Inorganic material, hence prone not termite attacks |
Prone to termite attacks |
Not prone to termite attacks |
