Selecting the Best Thermal Protection Solution

When deciding on the best thermal protection solution for your application, there are a number of different factors that must be taken into account. Below, we will explore key selection criteria.

Materials

When choosing a thermal protection material, you will want to answer some key questions, such as:

  • What is the continuous operating temperature? What about maximum or minimum temperatures?
  • Will the material be exposed to any chemicals or other environmental factors?
  • How important is durability?
  • Do you care about the aesthetics of the product?
  • What are the desired thermal properties?
  • What is the target cost?

Our Davlyn and Darco facilities work with a wide variety of materials (e.g. fiberglass, silica, ceramic, basalt) and enhancements (e.g. silicone, graphite, vermiculite, acrylic saturant, foils). This flexibility allows us to provide the optimal solution for your specific application. Many times, there is no “one size fits all” solution.

Construction

Mechanical and thermal properties can vary greatly, depending on the construction.

  • Expandability
  • Flexibility
  • Thermal conductivity
  • Durability
  • Aesthetics

Woven products offer a denser construction and are used for products such as tapes, cloths, and blankets. Different weave patterns are available to enhance aesthetics as well as the physical characteristics of the fabrics.

Braided ropes and sleeves have a dense structure with more flexibility than woven or knitted products due to their angled braid design. This characteristic makes braided products an excellent choice for creating thermal gaskets that must accommodate corners or curves.

Knitted construction is typically the most economical option. It has a less dense and more open structure compared to braided or woven, while still providing excellent heat resistance for many applications. Both circular and flat products can be created by knitting.

Function

Next, it is important to define the functional requirements. What are your primary objectives?

  • Life safety
  • Aesthetics
  • Thermal performance
  • Physical characteristics
  • Keeping heat in or out?
  • Conductive vs. convective vs. radiant?

Installation

How important is ease of installation for your application? This answer can lead to certain product decisions, including:

  • Integrated installation features (hook & loop closure, mechanical fasteners, zippers, etc)
  • Coatings or additional layers to improve durability during installation and transport
  • Packaging – bulk, boxes, or reels
  • Custom kitting

Economics

Lastly, you must consider the complete life cycle cost. The thermal protection solution with the lowest total cost of ownership may not always be the most obvious! Key variables that can impact cost include:

  • Materials and methods of construction
  • Product design complexity
  • Packaging
  • Scope of work
  • Long-term commitments

As you can see, there are many options when it comes to selecting the right material to use for thermal protection. As specialists in thermal protection solutions, our team will work with you to select the highest-performing, cost-effective solution for your heat application. Contact us today!
