A GLT Products company



Uniquely designed for ease of application over large diameter tanks, vessels, and pipes or any curved surface requiring the benefits of Stone Wool, Polyisocyanurate, Foamglas® or extruded Polystyrene. Ideally manufactured with a variety of facings, these products offer excellent thermal properties while providing the contractor low installation costs.

Foamglas® Fabricated Pipe and Fitting Insulation

Foamglas® insulation can be fabricated for pipes, equipment, vessels, and tanks. These fabricated pieces can be found in chemical processing lines, above and underground steam piping along with chilled water piping. Cellular glass insulation has operating temperatures from -268° to 482°C.

  • Zero water vapor permeability and moisture resistant
  • Easy installation
  • Long-term dimensional stability
  • Fire resistant
  • High compressive strength
  • Fitting types include: 90º and 45º Elbows, tees, pipe covering and segmented
Stone Wool Fabricated Pipe and Fittings Insulation

Stone wool pipe insulation is fabricated from felted stone wool bonded with a high-temperature binder.  Our stone wool pipe fittings can be fabricated from ProRox® SL 460 NA, ProRox® PS 960 NA or ProRox® PS 980 NA. The ProRox® PS line offers an innovative water repellent binder called WR-Tach. The resulting product is precisely fabricated to fit NPS and tube sizes for both commercial and industrial applications. The temperature range is from -20ºF (-29ºC) to 1200ºF (649ºC). GLT Fabricator stone wool fabricated pipe insulation is a water repellent yet vapor permeable material. All fabricated stone wool pipe insulation is made to order. Please consult your GLT Fabricators sales rep for custom ordering details.

  • Dimensionally (thermally) stable
  • High impact resistance
  • Low moisture absorption
  • Fire resistant and chemically inert
  • Excellent sound properties
  • Excellent thermal resistance
  • Non-corrosive
Extruded Polystyrene Fabricated Pipe and Fittings Insulation

Extruded Polystyrene Pipe Insulation (XPS) is a rigid, closed cell insulation offering excellent resistance to water and water absorption from freeze-thaw cycling. XPS Extruded Polystyrene Pipe Insulation has a service temperature range of -297°F to 165°F.

  • Does not soften or lose its strength at elevated temperatures
  • Excellent insulator
  • Lightweight and easy to install
  • Minimum compressive strength of 25 psi
  • Fitting types include: 90º and 45º Elbows, tees, pipe covering and segmented
Polyisocyanurate Fabricated Pipe and Fittings Insulation

Polyisocyanurate pipe insulation is a closed cell, high-performance insulation for pipe, vessel, equipment and duct applications. Can be used within the service range of -297°F to 300°F. GLT Fabricators also uses foam material manufactured by Duna Group USA for our fabrication processes. Please discuss with your sales rep if you have any special needs.

  • Greater dimensional stability over a wider service temperature range
  • Low thermal conductivity
  • Lightweight and easy to install
  • Wide choice of adhesives and coatings can be used for bonding
  • Excellent moisture resistance
Phenolic Fabricated Pipe and Fittings Insulation

Phenolic foam insulation is a closed-cell rigid phenolic foam insulation, fabricated in a variety of shapes and sizes to meet your exact specifications. This rigid insulation is supplied in the form of large buns for fabrication into pipe, curved segments, sheets, tank and vessel coverings, and other shapes for a variety of thermal insulation applications. It has a service temperature range of -297°F to 257°F.

  • Excellent thermal conductivity
  • Exceptionally low flammability
  • Superior compressive strength
  • low flammability
Calcium Silicate Fabricated Pipe and Fittings Insulation

Calcium Silicate pipe and block insulation is the product of choice for high-temperature pipe and equipment due to its high strength and durability, low thermal conductivity and corrosion inhibiting performance. Calcium Silicate insulation is especially recommended for use in the petrochemical, power generation and process industries where piping and equipment operating up to 1,200°F.

  • Excellent resistance to damage
  • Noncombustible insulation
  • Structural strength protects against damage to lagging
  • Asbestos, mercury, and lead-free
  • No organic binders


Choosing the correct insulation type will dramatically improve thermal efficiency and energy consumption in Commercial and Industrial piping, equipment and underground piping applications.

These products are ideal for tanks, spheres, and vessels. Fabricated insulation products are made to order for the desired fit and require minimal labor and provide zero waste.

Extruded Polystyrene, Polyisocyanurate, Stone Wool and Foamglas® provide insulation for temperatures ranging from -300ºF to 1200ºF. Lightweight, easily installed, low moisture absorption, excellent thermal resistance, high strength and non-corrosive qualities make fabricated insulation the perfect choice for off the shelf alternatives.
