TUFFINSUL LAMELLA

Product : Up to 750 °C
At temperatures in excess of 230 °C a limited migration of binder may occur in the insulation in contact with the hot face. This does not impair the insulation performance.

Applications

TUFFINSUL Lamella is used for thermal and acoustic insulation where high compressive strength is required. It is commonly used in heavy loaded sandwich panels, floors and roofs.

How to use Lamella?

Check the fiber orientation of the TUFFINSUL Lamella before sandwiching in between two metal surfaces with glue. Utmost care should be taken to ensure that the fibers are oriented perpendicular to the width of the two metal surfaces, in order to achieve optimum compression strength.

Installation Procedures

Before installing TUFFINSUL Lamella, make sure to clear away any dust or grease and dry the surface, and then place carefully over the surface to be insulated. Care should be taken to ensure that the Lamella fits properly and no gaps are left at the joints. Depending on the surface and equipment, pins or spacers should be used to fix the Lamella in place.

HOT & COLD INSULATION

Rockinsul and Tuffinsul exhibit excellent thermal insulation properties. The thermal performance of a product is indicated by R value and K value. R value is a measure of thermal resistance. Higher the R value, greater is the insulation efficiency.

An R-Value (thermal resistance) indicates the insulating power of an insulation material. The higher the R-value, the greater the insulating power i.e more energy savings.

ACOUSTIC INSULATION

As commonly defined, Noise is a sound that is loud or unpleasant or that causes disturbance. Sound is measured in a unit called the ‘decibel’ (dB). Our hearing range starts at 10 decibels (dB) and is considered safe up to 70 dB. Any prolonged exposure of sound of around 90 dB will lead to permanent damage to human ears. Extensive destruction and pain to the auditory nerves occurs at 140 dB. and destruction and
persistent ringing in ears will occur immediately at 150-160 dB.

There are two types noise control in buildings.

Air Born Sound – sound coming from air when the sound is produced directly to the air, like speech, sound from radio, TV, airplane.

Structure born are the sounds created when someone walks on a floor close to the flat, objects falling on the floor, house hold appliances etc.

Reverberation time is the time taken for the sound pressure level to drop by 60 dB after the generated noise has been stopped.

Areas with a long reverberation time are referred to as being ‘live’, e.g. cathedrals and churches. Those with a short reverberation time are referred to as being ‘dead’, e.g. offices with thick carpets and absorbent ceilings.

A reduction of 60 dB in the sound pressure level is equivalent to the reduction of acoustic energy by a factor of one million. As a rough guide, the reverberation time of a room is approximately equal to the time it takes for loud clapping to become inaudible.

STC (Sound Transmission Class) value is a single number rating to specify the reduction in sound levels that the partition provides. The sound transmission loss performance of a partition is measured using ASTM E 90 “Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements” and calculated according to ASTM E 413 “Classification for Rating Sound Insulation.” As a general rule, the higher the STC rating, the better the partition’s acoustical performance.

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

An IIC (Impact Isolation Class) rating describes the impact noise that is transmitted through a floor/ceiling assembly. The rating is determined by ASTM E 492 “Standard Test Method for Laboratory Measurement of Impact Sound transmission Through Floor-Ceiling Assemblies Using the Tapping Machine.” High ratings indicate that impact noise is reduced substantially.

Resilient channels are strips of metal with an offset that spaces the drywall approximately ½” away from the framing. They are typically installed 24 inches on center perpendicular to the studs. The use of resilient channels dramatically reduces the amount of sound that is conducted though the structure.

Q: Are there advantages to using steel studs over wood studs?
Twenty five gauge steel studs provide superior sound control performance to wood studs with the same dimensions. The flexibility of the studs allows the partition to provide performance equivalent to a wood stud construction with resilient channels.

FIRE SAFE

Insulation for Building or for Industrial application will help to save energy when installed correctly; but selecting the right type of insulation material is very critical when it comes to fire safety and for insurance claim in case fire accident. Non combustible insulation products will prevent the spread of fire, reduce the emission toxic smoke and more importantly it will provide vital extra minutes to save lives and prosperities.

Rockinsul and Tuffinsul product are approved by globally recognized testing agency like FM, UL and Warrington for exhibiting higher fire rating.

Rockinsul and Tuffinsul insulation products is made up of Basalt rock, therefore it resists temperatures upto 1000’C and will not burn
It acts as a fire barrier and minimizes the fire spread
Reduces the environmental damage
Does not emit toxic smoke
Provides valuable extra minutes to save life and property.

SUSTAINABLE

All the products produced by us have always been free from gases that are harmful to the environment such as CFC’s, HCFC’s , HFC’s pentane or any gases. Rockinsul and Tuffinsul insulation products is one of few products that can save more than 100 times the energy used for its manufacture. It conserves scarce energy resources and reduces air pollution, CO2 emission and Sound pollution.

We can contribute towards sustaining this mother earth from any further irreversible damages. Power plants contribute to nearly half the world’s man-made Co2 output. In India 67% of the total electricity produced are from thermal plants. Over 65% of total install capacity are coal fires, 10% gas based and less than one percent other fuels. Power plants emit nearly 1kg of Co2 for kWh.
