Specify Extol of Ohio, Inc Mechanical Joint Insulation Systems and Covers that Fit!

Extol of Ohio, Inc., in business since 1962, has specialized in providing quality fabricated insulation systems for all types of applications. We use cellular, rigid materials to supply constant thermal performance plus moisture and corrosion resistance.

EXTOL Advantages

Our quality, precision cut 2-piece insulation mechanical joint covers fit the contour of the most complex shapes. This reduces installation time and saves you money. To provide a USDA accepted system for indoor insulation, we have teamed with manufactures to provide heavy duty (.030in.) white PVC fitting covers.

Colors are also available

Through our continuing development efforts we now provide custom matching PVC covers for 90’s, 45’s, Y’s and couplings that fit. Until recently these had presented the insulator with time consuming field fabrication. This also provides a more consistent and thermally efficient insulation system when compared to fibrous insulations.

Meeting Demanding Deadlines

Each pre-formed cover is custom fabricated to meet your demanding project requirements and schedule. Experience Extol’s on-time performance!

Installation Practices

A full set of Extol Recommended Installation Practices are available to insure the optimum in performance and service life.

Reduced Energy Expenditures

Un-insulated fittings, valves and couplings create excessive heat gains or loss. Extol’s Mechanical Joints Insulation will equip your system with continuous process control. Call us for assistance with an Energy Analysis of your specific application. The return on investment data may aid in the justification of expenditures for insulation upgrades to your facility or for your client.

Other Capabilities

At Extol of Ohio, we have gone one step further than just the fitting component. We furnish an “Entire Insulation System for your project” utilizing Styrofoam, Isocyanurate, Cellular Glass, and Phenolic.

Our recommended insulation applications incorporate appropriate accessories, such as; weather and vapor barrier jackets and cladding, mastics, caulking and joint sealers which are compatible with each insulation product.Mechanical components of the system, such as; vapor stops, expansion/contraction joints, supports and slip-joints are detailed.Worst case scenario recommended insulation thickness charts suggested by the manufacturers are provided. And, there is an Inspection Check List provided for your project managers.

Compatible Systems

Extol has formed alliances with the most recognizable manufacturers of mechanical joint pipe systems. These include but are not limited to Victaulic, Gruvlok, Grinnell and Viking. Our capabilities extend from the smallest tube size to the largest pipe diameters found on your major projects.

We fabricate insulation to fit the following mechanical joint items:

  • 90’s
  • 45’s
  • Y’s & Tee’s
  • Valves
  • Unions
  • Pipe covering

Fabrication Notes:

All insulation; Styrofoam, Isocyanurate, Cellular Glass, and Phenolic conforms to the exacting tolerances of ASTM C450 and C585. Some fittings may have as little as 5/8″ thickness of insulation on the back of the couplings. Please specify when requiring additional thickness.
