Sound Attenuation Solutions

Diesel-powered equipment offers some tremendous advantages, but it does come with one consistently difficult challenge: Noise. The ambient noise levels caused by diesel equipment can be deafening, which can pose a substantial safety risk to operators and personnel. Decreasing this risk requires a careful sound attenuation strategy.

While insulation blankets may help to dampen sound, they are often far more effective when combined with specialized sound attenuation material like barriers, panels, or curtains. Firwin’s experts draw on decades of experience in sound management to engineer a solution customized to meet the needs of your facility.

Background: What is Sound?

Understanding sound attenuation technologies requires a bit of background on what sound actually is. At its simplest, sound is a vibration that the ear can interpret based on changes in atmospheric pressure. The level of perceived sound pressure depends not only on what causes this initial vibration but also on the acoustic traits of the surroundings. Some rooms will naturally amplify sound waves while others are specifically designed to absorb and minimize the disturbance before it reaches the ear.

Sound can be quantified in Decibels (dBs), which is especially useful when discussing personnel safety. The human ear can only tolerate certain noise levels without sustaining damage, up to and including permanent hearing loss. OSHA standard 29 CFR 1910.95 dictates the upper limit of tolerable noise as being 85 dBs.

Sound can also be classified by frequency levels, which are interpreted to the ear as different pitches. These vibration frequencies are measured in Hertz (Hz). Isolating and addressing a noise problem requires careful attention to both frequency and volume.

To do this, analysts will break down all present frequencies into eight or nine octave bands. They will then analyze the resulting octave band frequency report in combination with a report of dB ratings in the same room. This provides a full picture of the acoustic situation in the room, allowing an engineer to develop a solution that addresses the specific problem in context of any physical constraints.

Sound Attenuation Materials

Insulation solutions typically combine several materials, each intended to either absorb or block sound. Providing physical barriers in this way can prevent sound leakage and decrease the overall level of sound in a room.

Different materials are better suited to noises of different frequencies. For instance, fiberglass and mineral wool are known to be very effective against high-frequency sounds. Lower frequency sounds are more complicated because they consist of longer wavelengths that are harder to absorb. In these cases, thicker materials and barriers must be used to absorb as much of the wavelength as possible.

Safety is another key consideration for material selection. Sound attenuation is typically necessary in hazardous industrial environments, meaning that any solution must be able to withstand intense heat and other harsh environmental factors. At Firwin, we construct our blankets using only non-combustible materials that conform to MIL and UL fire standards, ensuring that all our products can hold up to extreme temperatures.

Firwin Solutions

Firwin takes pride in offering custom solutions for every client we work with, selecting the most appropriate materials and structures to match the layout and operating conditions of every facility.

Industrial Sound InsulationFor engine rooms, we typically choose to insulate the walls with tightly packed fibrous glass, mineral wool, or open-cell foam panels, providing effective absorption of high-frequency noise. In other situations, we might opt for a composite such as Firwin BTMM14C. Composites are advantageous when there is a fuller octave spectrum of noise pollution present.

We’ll also consider whether your equipment requires regular maintenance or inspection. If so, we might include removable sound blankets as a part of your solution, making it easy to remove and replace as needed.

We understand that sound attenuation can be complicated, so we’ve created a whitepaper that simplifies material selection for facilities working with diesel equipment. This resource breaks down the most common absorption materials, including comparison charts and tables. It also presents transmission loss and STC information for our composite absorber/barriers used in engine rooms and containers.

Insulation & Underground Mining: How to Increase Mining Equipment Safety with the Right Insulation

Underground mining operations may differ around the world, but they pose similar risks to worker health and safety. Different techniques are used to extract metals, gems, coal, and other materials, but the hazards are similar for most of these applications. According to the United States Department of Labor, Mining Health, and Safety Administration (MHSA), 70% of mining accidents in the U.S. involve using heavy machinery and other equipment at worksites.

Mining Safety Challenges and Worker Risks

According to the MHSA, the following are among the top causes contributing to accidents in 2012:

  • A lack of safety training
  • Poor hazard communication
  • Insufficient lockout/tagout precautions
  • Faulty electrical wiring
  • Improper machine guards
  • Hydraulic oil spills igniting on hot engine surfaces
  • Oil seeping into insulation covers, which poses a potential fire hazard
  • Operators burned in confined mine tunnels
  • Insulation failing to meet machine-guarding requirements

How Insulation Meets These Challenges

At Firwin, we offer insulation solutions that help to address the safety challenges posed by mining applications. These include:

  • Our MineWrap™ removable insulation blanket, which features an inner lining fabricated from stainless steel, prevents oil from being absorbed into the insulation. MineWrap’s™ exterior can be reinforced with a stainless steel mesh cover to make the blanket more resistant to punctures and the rugged underground mining environment.
  • Firwin’s Hard Coat™ composite insulation, a permanent insulation solution applied directly to the component that is being insulated. This is in contrast to MineWrap™, which is wrapped and fastened around the engine or exhaust components and can be removed and reinstalled.

Whether mining operations choose permanent or removable insulation solutions, insulation from Firwin ensures that the insulation material will be completely enclosed and shielded from exterior elements. This mitigates the dangers posed by equipment oil and fluid leaks that could otherwise seep into the insulation and pose fire hazards.

In addition, proper insulation reduces the ambient heat of diesel-powered equipment, and shields workers from burns. Using proper insulation also helps catalysts burn exhaust pollutants more effectively by maintaining the optimal high exhaust temperature as the exhaust travels along the piping.

Improved Mining Safety with Firwin

Underground mining operations inherently pose health and safety risks to the workers in the mine. Among the biggest causes of mining accidents are electrical wiring, machine-guarding, and oil seeping into insulation covers. Proper insulation is critical to safe operation, especially when used for machine-guarding.

Insulating exposed hot exhaust components is important in underground mines, but will only be effective if users select the correct insulation system. Failing to do so may add new safety concerns in the mine. Firwin’s MineWrap Removable Blankets and Hard Coat Composite Insulation are specifically designed to effectively insulate exhaust components used in mining operations in a way that addresses many of the safety hazards common among underground mining operations.

Firwin is a leading manufacturer of custom insulation products for exhaust systems, combustion engines, and an expansive range of other industrial purposes. Our main product lines include removable insulation blankets and permanent Hard Coat™ composite insulation. We are an experienced company that has been providing safe and effective insulation solutions to a wide range of industries since 1982.

In addition to providing high-quality insulation products, we are committed to offering superior customer service through product selection, sales, installation, and beyond.

Fasteners 101

Firwin’s removable insulation blankets are generally fastened with stainless steel lacing wire, which we supply with most of our insulation orders. Occasionally, a customer requires an alternate fastening system. Sometimes, the customer’s application may require quick installation or frequent installation and removal of the insulation blankets.

To suit the needs of these customers, we also carry several types of fasteners. Our versatile range of insulation blankets can also be fastened with straps, snaps, springs, and Velcro. These options provide alternative fastening systems and more accessible ways of opening and closing insulation blankets.

Every fastening method has benefits and idiosyncrasies, making it is important to consider which one is right for your application. While choosing a fastener type for your insulation blanket, you should ask yourself the following questions.

  • How often will the insulation blanket be accessed?
  • Are there any environmental factors, such as temperature, potential water exposure, or corrosive elements, that need to be accounted for?
  • What will the installation process look like?
  • How much give do you require from your insulation blankets?
  • Is this a self-install or will you use a professional contractor?

With answers to those questions, you can go about choosing the fastener that is right for your specific application.

Applications and Benefits of Each Fastener Type

As outlined below, each fastener type is suited for specific applications:

Stainless Steel Lacing Wire

stainless steel lacing wireOur most common insulation blanket fastener is stainless steel lacing wire. Stainless steel lacing wire provides an extra secure fit and durability.

Benefits provided by stainless steel lacing wire include:

  • It can be bent or tied into any configuration necessary.
  • Stainless steel is highly corrosion resistant.
  • It is highly durable, and so you will not need to maintain or repair it.


 Our silicone or Teflon straps can be used to fasten insulation blankets for a speedy installation. The benefits of straps include:

  • Can be pulled taught for snug fit
  • Straps are strong, weather-resistant, non-abrasive, and low-stretch
  • Straps can be fitted into a variety of locations.
  • Easier and more intuitive than lacing wire


spring fastenerFirwin created our own proprietary spring system for attaching insulation blankets. Unimpressed with other spring fastener solutions, we worked with a local manufacturer to develop a spring fastener that was simple to use with a long service life. Some of the benefits of springs include:

  • Springs are corrosion resistant, making them ideal for applications with corrosive environmental factors.
  • They can be taken on and off easily for temporary applications or uses that require frequent removal and reinstallation.
  • Springs maintain their integrity over time; they do not degrade.
  • Springs can operate at high temperatures.


snap fastenerWe also offer snap closures to our insulation blankets, a cost-effective alternative. The benefits of snaps include:

  • Excellent shear strength.
  • Can be released quickly and easily when pulled at from an angle, making them great for quick-removal applications.

Snaps may not be an appropriate fastening solution for blanket setups that have complex geometries, or in applications that require give when fastening the blankets.


velcro fastenerVelcro offers an ideal solution for fastening blankets quickly and easily. The applications vary widely for Velcro, as it can be used on its own or as a supporting fastener in conjunction with other fasteners.

Velcro is made of a variety of materials, such as stainless steels, nylon, and polyester Which type of Velcro should be used will depend entirely on the application. As the tiny Velcro hooks are vulnerable to damage, it’s critical to ensure that the Velcro material can handle environmental factors of the operation. For example, high temperature applications may require more expensive Nomex or stainless-steel Velcro.

The benefits of Velcro as a fastener for insulation blankets include:

  • Easy installation and removal
  • Good for low temperature applications
  • Affordable (though certain Velcro types such as Nomex or stainless steel come at a premium)

Fasteners from Firwin

There are many different fastening methods  available; the most appropriate method for a given application depends on a number of variables – cost, temperature, frequency of removal, speed of installation, and others.  At Firwin, we work together with our customers to arrive at the best fastening method for their particular situation.

To learn more about the types of fasteners that Firwin offers, or with questions about fasteners for your specific application, please contact us today.

Case Studies

For a better illustration of how Firwin helps our customers, a couple of case studies are outlined below.

Ship Lagging Overhaul: A Marine Application

  • Problem — A fleet of drill ships was experiencing torn exhaust lagging, or insulation. The customer wanted Firwin to construct removable insulation blankets that would meet specific size and thickness specifications set by the customer. Rather than just produce blankets to a specific spec without knowledge of the components they were meant to cover, Firwin encouraged the customer to share more of their product details and allow Firwin’s engineers to determine the most appropriate blanket design that would best meet the customer’s needs; the customer agreed.
  • Solution — Firwin’s design team prepared two options for the customer, both elegant solutions that would cover both the exhaust flex and upper/lower flanges while meeting the customer’s specifications: 1) a single blanket that would cover the flex and the flanges (similar to the client’s original solution), and 2) a three-blanket solution, in which separate blankets would be made for the flex and flanges. The customer chose the three-blanket solution, as it would provide more flexibility and greater ease of use.

Heat Flow Analysis and Containment: A Non-OEM Application

  • Problem — A company needed to insulate a silencer located in their in-house testing room as they were concerned about its high heat generation within the limited space. To assess how much insulation would be required to properly protect the equipment, Firwin conducted a heat flow analysis.
  • Solution — Using new flow simulation software, a dramatic improvement over past technology, the Firwin team was able to use accurate data validation to inform the client’s insulation decision. Firwin’s heat flow analysis indicated that only the top of the silencer needed to be insulated to achieve the desired heat containment. The client moved forward with insulating the recommended portion of the equipment and successfully reduced the silencer’s heat generation, without needlessly spending money on blankets for the entire silencer body.

Find the Custom Solution You’ve Been Looking For

Beginning as a small family business, Firwin has grown to become an industry leader in custom insulation products for wide-ranging industrial applications across the world.

Gimme Some Space – How Much Clearance is Necessary for an Insulation Blanket?

Insulation Blankets – Thicknesses and Clearances

It is important that there is enough room around any component being insulated to allow enough space not only for the insulation blanket, but also for sufficient air space between the insulation blanket and any nearby surfaces. A lack of air space between the outer surface of an insulation blanket and another object can cause a heat build up on the blanket’s outer surface and possible deterioration of the blanket material.
With the typical blanket thickness of one inch, the question arises as to what to do with applications that require removable insulation, but have low clearances around all or part of the components to be covered?
“Insulating areas with low clearances can be an issue, but it often depends on the particulars of an application and what the client is

wishing to achieve”, said Brett Herman, Firwin’s VP of Sales & Engineering. “For instance, sometimes just thinning out the insulation in areas of low clearance will still give the client sufficient insulation performance for the needs of his particular application. If, on the other hand, we are dealing with a relatively high temperature application, and the client has a particular temperature reduction goal that he wishes to achieve – this could be for personnel protection, or to ensure that nearby heat sensitive components are shielded from overheating – Whatever the reason, a lack of clearance means we are limited in the thickness of insulation that we can apply, which in turn can limit the amount of heat reduction that results”.

Solutions for Low Clearance Issues

So what solutions are available for situations where clearances restrictions would seem to limit the use of insulation blankets? “In situations where the client needs to achieve a certain temperature reduction, and there is insufficient room for the thickness that would be needed with standard fiberglass insulation, we have other solutions that we can offer to help the client achieve his goals”, said Brett.
“The first possibility we would look at is upgrading to a higher temperature insulation, such as MW1800 or FW2000+. These insulations have a higher temperature rating than our standard fiberglass FW1200, and sometimes when all that is needed is a small increase in insulation performance at a given thickness, these insulations will do the trick, with the price premium being relatively small “, notes Brett.
“If however, these do not suffice, the next step is to look at a high performance insulation such as Aerogel. It does carry a price premium, but it is one of the most effective insulators on the market, and will allow a client to achieve larger temperature reductions with a thin layer of insulation”.

High Performance Insulators

Insulation blankets are made up of 3 parts: The outer cover, also known as the `cold face`, the middle layer of insulation material, and the inner cover, or `hot face`. For most applications, the `standard` insulation blanket makeup of a silicone outer cover, 1 inch thick fiberglass, and a mesh inner liner, works fine. But certain applications demand alternative materials, be it because of very high temperatures, the environment where the insulation blankets will be operating, or in the case here, because of a combination of space constraints and desired insulation performance.

“Space constraints alone do not necessarily demand the use of an alternative insulator such as Aerogel”, said Brett. “It is possible that the customer`s needs can be met with a thin layer of fiberglass or superwool. An insulator like Aerogel is brought into the picture when the project needs insulation performance that typically could only be achieved with thicker insulation than the space allows.”

The chart below gives an indication of what kind of insulation effectiveness can be achieved even with a very thin layer of Aerogel insulation, compared to other insulations at standard 1″ thickness. As can be seen, even a thin 10 mm (approximately .4 inches) layer of Aerogel gives an insulation effectiveness near that of a 1″ thick fiberglass blanket.

Can removable insulation blankets keep pipe contents from freezing ?

Removable insulation blankets are great at managing heat. Be it by lowering the ambient heat in an engine room, protecting workers from hot surfaces, or shielding pipe contents from cold external temperatures, removable insulation covers are often the solution of choice where heat must be managed, but permanent insulation is not feasible.

Gate Valve with Glycol Tracing,,
wrapped with Removable Insulation Blanket

But there is one thing that removable insulation blankets cannot do – they cannot add heat. “We often get asked, particularly in cold weather applications, if our blankets can keep pipe contents or components from freezing”, said Brett Herman, Firwin`s VP of Sales & Engineering. “The answer is that while we can contain heat and delay heat loss by sheltering pipe components from cold external temperatures, our insulation blankets can`t add any heat that isn`t already there.”

Where insulation blankets can help, however, is where companies have some sort of heat tracing on their piping, and they want to minimize the amount of heat lost to the environment, and thus maximize the efficiency of their heat tracing.

Heat Tracing Challenges

“Companies, particularly in the oil and gas industry, and often in other industries such as mining, chemical, and food processing, use heat tracing to keep pipe or container contents from freezing. In cold temperatures, this heat tracing, if left un-insulated, becomes much less effective. Firwin has done a number of applications in this area, covering the component and the heat tracing, increasing efficiency and lowering the heat that escapes to the environment”, added Brett.

Like other removable insulation blanket applications, a properly designed blanket is key to ensuring that the heat tracing is properly insulated. “There are various type of heat tracing in the marketplace today – steam, glycol, hot oil, and electric”, said Rael Herman, Firwin’s VP of Production & New Product Development.

“In some instances, the entire component in covered by a ‘bolt-on heat jacket, changing the entire geometry of the part”. What they all have in common is the need to be wrapped tightly, so as to minimize the amount of heat that is lost to the environment. The challenge, when it comes to insulation blankets, is to design a blanket that will account for the sometime difficult geometries and penetration access points that often come hand in hand with heat tracing”, said Rael.

Firwin Blanket custom designed to fit glycol penetrations

Other Solutions

What about situations where the customer is not familiar with heat tracing, or where heat tracing is not a viable option ? “We have done applications where we have incorporated a heat source into the insulation cover (see previous article on “pizza blankets“)”, notes Brett. “Regardless of who supplies the heat tracing, what’s important is ensuring that the the insulation blankets are designed in such a way as to tightly cover the components in question, while allowing for penetration points that typically accompany tracing of valves and similar components”.

Firwin FireBlanket 2000 Can Take the Heat: It’s Proven to Withstand Temperatures as High as 2000-Degrees-Fahrenheit!

In our last blog post, we reviewed how the Firwin FireBlanket 2000 protects industrial safety valves and actuators.
We explained how a removable insulation blanket designed to protect safety valves is different from the standard insulation blankets you’ll find in industrial settings. In this blog post, we’ll talk more about the design of this type of fire blanket and explain how strong and durable it is (and why it needs to be this way!).

The Firwin FireBlanket 2000 is designed to keep the heat and fire away from the part. Typically, removable insulation blankets are composed of three layers:

1. the inner surface
2. the insulation material that rests on the inner surface
3. the outer protective cover.

In most cases, the removable insulation blanket’s inner surface is the “hot face” that comes in direct contact with the hot component. However, the Firwin FireBlanket 2000’s outer protective cover is the “hot face” and it needs to withstand extremely high temperatures. The FireBlanket is working “in reverse,” in layman’s terms: The outer surface and insulation are protecting the part from the heat, and the outer protective cover needs to withstand the very high heat of a fire.

There are also other variables that come into play in a fire safety situation at an industrial plant, and time is a critical factor. The valve or actuator being protected by the FireBlanket will need to function and operate properly to allow enough time for the operator to shut down a line. In situations like this, a FireBlanket’s outer cover may deteriorate too quickly if it’s not manufactured to meet certain fire standards. It’s also important to install the FireBlanket so that the component is properly protected – an improperly installed FireBlanket could impede the blanket’s ability to protect the component in case of fire.

The Firwin FireBlanket 2000 easily passed the UL rapid rise fire standard test (UL1709) where it was placed in a special compartment and blasted with 2000-degrees-Fahrenheit temperatures for 30 minutes. The fire blanket – including its outer protective – remained fully intact throughout the test, with no signs of deterioration at all. This proves that the Firwin FireBlanket 2000 can definitely take the heat!

A Fire Blanket Designed to Protect Industrial Safety Valves is Definitely Worth the Investment

You’ve probably heard about fire blankets that are designed to protect people in their homes or in their workplaces. These types of fire blankets are commonly used to extinguish and smother fires or as portable safety devices to wrap around people as they run for safety. But, have you heard about fire blankets that are designed to protect industrial safety valves and equipment?

Fire blankets designed to protect industrial safety valves are a type of insulation blanket, but they differ from standard insulation blankets used in industrial settings. Standard blankets are meant to insulate a part to maintain a high level of heat inside the part, or to keep heat away from the outside environment. For instance, in many industries, machine and equipment parts must be kept at the right temperature for the part to function properly; conversely, heat must be contained and kept away from the surrounding area, be it for personnel protection or protecting nearby heat sensitive components. However, fire blankets designed to go over a part – typically a safety-related part, such as a gate valve or an actuator – are designed to keep the heat and fire away from the part. These types of fire blankets are needed in many industries, including the oil and gas industry.

A fire blanket that protects a valve, an actuator or another part from fire and heat is a critical industrial safety tool. Gate valves and actuators function as safety mechanisms in industrial settings. In the event of any type of fire, including chemical fires, these actuators perform a safety shutdown to reduce fire spread and prevent or minimize disaster. The fire blanket is designed to go over a valve or part to protect its covering long enough for safety procedures to function properly. Designed to withstand a fire for up to 30 minutes, this allows enough time for an operator to actuate the safety function on a line and to perform a shutdown to keep the fire under control and to minimize potential damage.

The fire blanket we offer at Firwin works to protect industrial valves and actuators so that they can do their job in a critical safety situation, and they’re proven to work: Our fire blanket for industrial safety valves and parts was tested in a UL rapid rise fire standard test (UL1709) where it was placed in a special compartment and blasted with 2000-degrees-Fahrenheit temperatures for 30 minutes. The fire blanket remained intact throughout the test.

A fire blanket designed to protect industrial safety valves and equipment is definitely worth the investment! To learn more about the fire blanket, read the article Firwin FireBlanket 2000 in our e-newsletter.
