What are USG ceiling tiles made of?

Radar acoustical ceiling panels are economical, medium textured panels that feature a unique, non-directional pattern. They are made with a water felted manufacturing process that provides excellent ceiling attenuation class (CAC) performance.

What is CAC ceiling tile?

Ceiling Attenuation Class (CAC): CAC indicates a suspended acoustic ceiling’s ability to block sound traveling through a plenum when the wall does not extend full height. High CAC values indicate higher levels of sound insulation between rooms. Suspended acoustic ceilings typically have CAC ratings between 20 and 35.

What are commercial ceiling tiles made of?

These are the most commonly used tiles in commercial suspended ceiling applications and are typically made from a mixture of waste paper, mineral fiber (which may include slag, a waste product from steel-making), cornstarch, and various other mineral-based components.

Can you paint USG ceiling tiles?

Typically, for ceiling tiles, you will use spray paint or flat-latex paint. Except for wood tiles. It is also easier to apply your paint with a sprayer rather than a brush or roller. However, a good brush and roller are great options too.

Is there asbestos in USG ceiling tiles?

Some USG containing ceiling tiles contain asbestos: Some but not all older US Gypsum Corporation ceiling tiles contain asbestos.

What is the difference between STC and NRC?

NRC is only the average of the mid-frequency sound absorption coefficients (250, 500, 1000 and 2,000 hertz) rounded to the nearest 5%. The Sound Transmission Class (STC) measures the sound transmission between spaces. A single number rating is used to measure the assembly’s barrier effect.

Is PVC ceiling tile safe?

Polyvinyl chloride is often used in moisture-resistant ceiling tiles. But PVC manufacturing releases many toxic chemicals, including harmful dioxin compounds. Vinyl chloride, used in PVC production, also poses a serious risk to workers.

Do USG ceiling tiles contain asbestos?

When did USG stop using asbestos?

Some products manufactured and sold by USG from 1920-1978 contained asbestos.

What happened to USG?

Buildings materials giant USG has agreed to be acquired by Knauf for $7 billion, in a deal which requires shareholder and regulatory approval. German manufacturer Knauf has agreed to buy Chicago-based USG for $7 billion, the companies announced Monday.

What is NRC ceiling?

The acoustic ceiling tile NRC rating refers to how much sound the ceiling material can reduce noise by absorbing sound. A higher number indicates more absorption.

What is a STC rating ceiling tile?

Overview. Sound Transmission Class (STC) is a measure for rating the performance of a wall system as a barrier to airborne sound transmission between adjacent closed spaces such as offices.

What is STC and IIC?

STC (Sound Transmission Class) is a measurement that indicates how much noise is stopped (absorbed) by the wall or floor ceiling assembly. ( airborne or voice noise) IIC (Impact Insulation Class) is a measurement that indicates how much impact noise is stopped in a floor/ceiling assembly.

What is the highest STC rating?

The STC rating goes all the way up to 65. Most products don’t promise anything above 55 and even at a rating of 60, it still doesn’t guarantee complete soundproofing. Nothing is completely soundproof. You cannot stop outside noise completely from entering your space.
