Firwin designs and manufactures removable blankets taking into consideration the end use and operating conditions under which they will be used. It is critical we understand the heat and environmental situation you are faced with. We can then design the best insulation solution for you.

Safety in the work environment is important to all of us, both from a human and business perspective. This means personnel protection from burns, reduction of ambient heat levels, fire hazard reduction and protection of sensitive sensors /cabling and fire sprinklers.

Firwin's removable insulation products meet ULC, Lloyds, GNV, NFPA, Coast Guard and MIL, Standards and Requirements.

Benefits

• All our removable blankets are designed to be retrofitted, installed OEM and fasten for easy installation and removal.
• Various practical alternative methods of fastening are available for different end uses including lacing, buckle fastening and Velcro.
• This means that they are maintenance and inspection friendly.

Firwin offers a range of different removable/reusable insulation blankets tailored to your special needs and requirements.

Materials

Due to the wide range of heat and environmental situations, we design our blankets taking into consideration the end use and operating conditions under which they will be used.

Once we understand your specific needs, we will determine the best materials to use. Our design process includes selecting the best material for:

1. Outer Cover Material (“The Cold Face”)

We select the most suitable outer cover material, given the environmental, wear, heat demands and economic considerations of the installation. Usually materials selected are coated or impregnated fibreglass fabrics with various finishes best suited for the particular high temperature range, chemical exposure, and liquid/oil resistance required.

2. Insulation Material

Different insulation blanket materials have specific temperature limitations so we select the insulation material most suited to the identified temperature conditions. We keep in mind bearing the material's maximum temperature resistance, thermal conductivity [“k”], it’s environmental acceptability, and vibration resistance.

3. The Inner Liner Material (“The Hot Face”)

Knitted SS wire mesh, which contracts and expands with heat is used, to hold the insulation material in place. Different qualities of SS mesh are used for Diesel and Gas engines. Specially coated fabrics are used for temperature ranges below 450°F (250°C).

Where oil build up is a concern, oil resistant inner liners can be used. If dust is a concern, silica liners can be added to the hot surface while being mindful of the limitations of high temperature products.

4. Fastening Systems

Depending on end use and temperature ranges, a variety of fastening systems are available, including capstan rivets with lacing wires, buckles and straps and high temperature velcro and snaps.
