Frequently Asked Questions
symbol What is NRC?
The Noise Reduction Coefficient (commonly abbreviated NRC) is a scalar representation of the amount of sound energy absorbed upon striking a particular surface. An NRC of 0 indicates perfect reflection; an NRC of 1 indicates perfect absorption.

In particular, it is the average of four sound absorption coefficients of the particular surface at frequencies of 250 Hz, 500 Hz, 1000 Hz, and 2000 Hz. These frequencies encompass the fundamental frequencies and first few overtones of typical human speech, and, therefore, the NRC provides a decent and simple quantification of how well the particular surface will absorb the human voice. A more broad frequency range should be considered for applications such as music or controlling mechanical noise.
symbol What are CAC ratings?
Ceiling Attenuation Class (CAC) ratings are used to determine the sound transmission loss through an acoustical or dropped ceiling. A CAC rating is determined by ASTM test method E 1414 "Standard Test Method for Airborne Sound Attenuation between Rooms Sharing a Common Ceiling Plenum" and provides a value that is equivalent to an STC value.
symbol How do me estimating that how Many Cartons I'll Need?
It's very simple three step process
1. Measure the length and width of your room. Round up to the next whole number of feet.
2. Multiply the length of the room in feet by the width of the room in feet and divide by the number of square feet of ceiling in each carton.
3. Round your answer to the next whole number to determine how many cartons you'll need.

symbol How much will a new ceiling cost?

Not as much as you may think. Techno Acoustic Ceiling is a very cost effective system, Pre Painted GI Ceiling Systems costs around Rs.80 Per sqft and Aluminum Ceiling System cost around Rs.100 per sqft (approx) however price will vary according to product design and performance features. We can provide ceiling system for various budget which starts from Rupees 80 per square feet.

symbol Can I paint my Techno ceiling tile or suspended ceiling?

All Techno Acoustic™ ceiling tiles and panels can be painted with latex paints. However repainting must be done on both sides of the panels. We cannot guarantee that the original specified surface burning characteristics, fire resistance ratings, acoustical performance, dimensional stability/sag or light reflectance after repainting.

symbol How many fluorescent lighting fixtures will I need?

Rule of thumb: Use two four-foot fluorescent tubes for every 75 square feet of suspended ceiling. Also, many Techno Acoustic™ ceilings provide good light reflectance which saves energy.
