High-temperature thermal insulation protects workers and equipment in environments with high heat generation. At Firwin we are here to help you select the right high-temperature insulation materials that can help you maintain safe operations while maximizing equipment longevity and efficiency.
High-Quality Insulation Material Options
Regardless of the material selected, your insulation solution should match the given component’s dimensions. Well-fitting material will be easier to use and will better prevent heat loss.
At Firwin Corporation, we offer several types of high-temperature thermal insulation materials to meet your equipment’s unique requirements. Our liners and covers consist of quality, reliable materials with custom options available for each application.
The following are the specific types of high-temperature insulation products available from Firwin Corporation:
- Firwin Plus. This high-heat insulation material consists of high-temperature, low bio-persistence insulation wool. This material boasts superior thermal stability, thermal shock resistance, low heat storage, and sound absorption.
- Firwin SW1800 Insulation. Firwin SW1800 is ideal for high-temperature applications requiring superior stability. Unique properties included with this material include thermal shock resistance, chemical resistance, and improved solubility when exposed to bodily fluids.
- Aerogel. This ultra-lightweight, high-porosity insulation delivers exceptional thermal performance in a thin profile, making it ideal for space-constrained applications and equipment operating up to 1,100°F. Its low-density structure and hydrophobic properties also make it well-suited for protecting fragile components in tight mechanical compartments.
- Board Insulation 15080 RHF™40. These materials comprise non-combustible ROXUL® mineral wool with a melting point of about 2150 F (1177 C), making it ideal for use in applications requiring reliable fire resistance. This lightweight mineral wool innately repels water and permeates vapor.
- Rockwool Board Insulation 8LB. Made of slag and basalt rock, this non-combustible insulation material is also highly resistant to fire with a melting point of approximately 2150 F (1177 C). It’s also highly water-repellant while allowing vapor through.
- Firwin Vermiculite-Coated Fiberglass Fabric. This high-temperature fiberglass insulation material consists of a plain weave with a vermiculite compound coating for superior temperature resistance. It can substitute ceramic fabrics and silica materials.
- Firwin 1200 Insulation Mat. With the ability to resist temperatures of up to 1200 F, this mechanically bonded glass fiber material works in many high-heat applications requiring uniform insulation. Its superior drapability allows the material to conform to many types of surfaces.

When Space Is Limited: Aerogel Insulation
In applications where clearance is tight but thermal performance can’t be compromised, Aerogel is often the best-fit solution among our high-temperature materials. A thin 10 mm layer of Aerogel can deliver thermal effectiveness comparable to a standard 1-inch fiberglass insulation blanket, making it a strong option for power generation, data center, and marine equipment operating in confined spaces. Aerogel also performs reliably in cryogenic and sub-zero conditions, extending its usefulness beyond high-heat environments alone.
