Firwin Corporation is a premier manufacturer of custom insulation products for gas/diesel engines and exhaust systems as well as industrial applications. We invest heavily in R&D to ensure that Firwin is at the forefront of the latest developments in the insulation industry. Our goal remains to offer our customers the best possible insulation solutions for their unique applications.
Here are some examples of products that have resulted from our R&D efforts over the years.

MineWrap™ Mark I and Mark III

If equipment malfunctions in underground mining sites, it can have disastrous consequences for workers and facilities. In the event of an engine oil leak or a leak from a burst hydraulic line, there is a danger of the oil seeping into the insulation material and catching fire. To prevent these hazards, our R&D team developed MineWrap™—a unique line of insulation blankets for wrapping underground mining equipment.
MineWrap™ Mark I and Mark III feature a foil and mesh inner liner that isolates the insulation material, as well as extra rigidity to withstand wear and tear in harsh environments. On the Mark III, we designed the outer liner with reinforced stainless steel foil and mesh for extra puncture resistance.

Permanent Hard Coat Insulation™

Click to ExpandResearch and Development

Our Permanent Composite Hard Coat™ is more durable and compact than most conventional insulation products. It can withstand extremely high temperatures and fit in tight spaces. This product is ideal for heat-prone applications like engines, exhaust systems, elbows, and turbochargers, where space is at a premium and removable insulation is not required. Clients in the automotive, mining, marine, and defense industries currently use the Permanent Composite Hard Coat™ to manage their heat-related issues.

Metal Foil Insulation

Firwin MFI Metal Foil Insulation is ideal for exhaust system parts (tubing, piping, elbows) that require pre-installed installation. The insulation is encased by an outer foil that is permanently welded to the part. It provides a visually appealing insulation cover that offers excellent durability, can withstand steam washing and solvents, and keeps fluids from seeping into the insulation material.

Fire Blankets

Our removable fire blankets are designed to protect heat-sensitive components from chemical fires. The blanket slips over the valve or other part to protect it from fires for up to 30 minutes. This gives the operator enough time to initiate safety procedures by shutting down the line, controlling the fire, and minimizing damage.
Our fire blankets have been applied successfully in the oil and gas and chemical industries.

Remote Scanning

In situations where it is impractical for clients or Firwin to take manual measurements at the client’s facility, we employ remote scanning technology to create digital replicas around which we design our insulation products. Some machines have complex geometries, making it challenging to get accurate, reliable measurements by hand. With remote scanning technology, the customer can scan their machinery and send the 3D models to Firwin. We use these models to develop accurate insulation products that fit the customer’s application and save on travel costs and time.

3D Printing

Firwin’s in-house 3D printing technology allows us to accommodate more complex designs and streamline the production process, ultimately saving our customers time and money. Our ability to 3D print exhaust component prototypes allows us to test fit our blankets in house, which is especially important when developing insulation blankets for new customer applications.


Firwin takes pride in innovation and excellence. We encourage our people to embrace an entrepreneurial spirit and provide cutting-edge solutions for demanding applications across diverse industries. Our research and development teams focus on continually improving existing products and adding new ones to benefit our customers.
