Water Resistance

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

Non-combustibility

Non-Combustable as per
BS 476 Part 4

Combustible

No Test Certificate available for tiles

Perforated metals will have poor light reflection

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.

0.10 to 0.7 (perforated with acoustic fleece)

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

Designer range ceilings
