Fastening systems are an important part of any insulation system. They secure the insulation, which is essential for preventing air leakage and maintaining thermal performance. Let’s look at the different fastening features and benefits.

Fastening Options

There are various ways to fasten removable insulation blankets, but the most common fastener is stainless steel lacing wire and rivets. This type of fastening is also often used for heavier blankets because it’s strong and durable. Other common fastening options include snaps, straps, Velcro, and springs. The best option will largely be influenced by your application type and budget, as each choice comes with its own set of benefits and disadvantages.

Fastening Features & Benefits

Rivets & Stainless Steel Lacing Wire

Rivets and stainless steel lacing wire provide extra-secure fastening capabilities due to their durability and flexibility. The material is corrosion-resistant and less likely to snap under tension, so it can be shaped and tied into any complex configuration.

Straps

Our straps are made of Teflon or silicone and facilitate quick, easy installation. Their benefits include:

  • Easy tightening
  • Weather resistance
  • Abrasion resistance
  • High strength
  • Low stretch
  • Fits in a variety of locations

Springs

Our patented springs were specifically developed to fasten insulation blankets. Their advantages include:

  • Corrosion resistance
  • Quick and easy installation and removal
  • Maintains strength over time
  • Works well at high temperatures

You can browse and purchase springs in our accessories store.

Snaps

Snaps are an easy-to-install alternative for simple geometry insulation blankets. They may not be the best solution for blankets with complicated geometries. The benefits of snaps include:

  • Good shear strength
  • Easy installation and removal
  • Durable and long-lasting

Velcro

Velcro can be made of various materials, including nylon, stainless steel, and polyester. The best type of Velcro depends on the application. This fastener is best for securing blankets quickly. Other benefits include:

  • Easy removal and installation
  • Suitable for low-temperature applications
  • Affordable (note: some Velcro types like stainless steel or Nomex are higher-priced)
