Fiberglass Snap-On Pipe Insulation – A preformed high-density resin-bonded Fiberglass insulation, molded in one meter lengths. A single longitudinal seam enables the sections to open and encircle the pipe and to snap closed after placement.

Technical Data

Snap on pipe insulation is specifically designed for application to both hot and cold service piping systems operating at temperatures from -20°C up to 450°C . Suitable for application on chilled water and refrigerated lines, hot water, steam & condensate lines, in domestic, commercial & industrial applications.

Available in a wide range of standard nominal bore steel and copper pipe diameters over a range of insulation thickness.

  • Lifelong energy savings
  • Excellent thermal & acoustic properties
  • Maintenance free
  • Available in a wide range of pipe bore and insulation thickness
  • Long product life
  • Ease of installation
  • Ease of fabrication – on site modifications is easy

OdourlessOdourless, inert & fully compatible with all standard building materials & components.
Vermin ProofWill not sustain vermin
Acoustic PropertiesExcellent thermal & acoustic properties
Life Long SavingsContributes to indoor comfort and contributes to life long savings by reducing heat loss/gain due to the inherent thermal insulation properties.
Non-CombustibleNon-combustible and Conforms to SABS. 0177 Part V
Fire PropertiesFire index conforms to SABS 0177 Part III (Class 1)
  • Will not breed or promote fungi, mould or bacteria
  • Will not promote corrosion of steel, copper or aluminium
  • Non-hygroscopic

Fiberglass pipe sections are manufactured according to ISO 9001 : 2008

Significantly reduces heat gains & losses – refer to nomograph for relevant thermal performance at various hot and cold face temperatures.

Install rigid non-combustible light weight “Snap on Pipe” Glasswool insulation with a nominal inside diameter of (15/20/25/32/40/50/65/80/100/125/150/200/250/300)mm and a wall thickness of (15/20/25/40/50)mm with (plain/canvas/M-Foil vapor barrier) facing for hot/cold service piping.


Excellent acoustic insulation.

Class 1 fire index – tested to SANS 10177 Part 3
Conforms to ASTM C547 for punking (fire) using ASTM C411 test
