Scope of work

What we bid and what we install

Seven offerings, taken from PFAFF's own description of its services.

  1. Mechanical insulation installation

    Pipe, duct, vessel and equipment insulation for commercial and institutional mechanical systems.

  2. Removable insulation jackets

    Custom-fabricated, strapped and re-usable covers for valves, flanges and vessel heads that have to be opened for service.

  3. HVAC insulation

    Supply and return ductwork, plenums and air-handling equipment, including vapour-sealed and weatherproofed assemblies.

  4. Thermal analysis

    Thickness and material selection worked against the operating conditions of the system rather than a default specification.

  5. Moisture and condensation control

    Vapour retarders and sealed systems on chilled and below-ambient lines, where a failure shows up as corrosion rather than heat loss.

  6. Energy audits

    Survey of uninsulated and failed insulation on existing plant, with the heat loss quantified.

  7. Maintenance and repairs

    Replacement of damaged, stripped or water-logged insulation and jacketing on systems already in service.
