  • Description
  • Advantages & Attributes
  • 7.2 Insul-Rib® – Material Specifications
  • Load Span Tables

The 7.2 Insul-Rib™ insulated metal wall panel combines a traditional 7.2 rib panel design with a polyurethane foam core. This widely used profile is available as an insulated panel in various thicknesses.

The 7.2 Insul-Rib™ panel has a standard FM Approved Class 1 foam core and offers excellent insulating values. The metal and foam composite construction creates a rigid panel far stronger than the individual parts. This increases the span capability of the panel and reduces the need for secondary structural components.

Superior Insulating Value across the entire wall and roof area is assured with 7.2 Insul-Rib™ panels. The advanced polyurethane core provides enhanced insulation values that significantly lowers heating and cooling costs.

One-Piece Construction process assures rapid completion of the wall and roof system. Factory fabricated composite panels are attached directly to the supporting structure and multiple steps to construct the insulated wall and roof are eliminated. Faster building completion means reduced construction and interim financing costs.

Lightweight yet Structurally Strong panels weigh only 2 ½ to 3 ½ pounds per square foot, but are structurally strong enough for long spans that can significantly reduce costs for frame support.

Impermeable Faces & Built-in Thermal Breaks ensure the highest insulating values are maintained for the life of the building. Panels are manufactured with impermeable faces and when installed the insulation is completely encapsulated by metal trim that creates an impermeable membrane on all sides of the panel. The aged “R” values are comparable to the initial “R” values many years after the buildings original completion. Assured thermal values mean lower heating and cooling costs.

Class 1 Polyurethane Foam meets the requirements of the major model building codes for many types of construction. Unlike panels with expanded polystyrene cores they will not produce a self-propagating fire. Local building codes may require automatic fire suppression systems for most installations.

Concealed Attachment with clips and fasteners at the side joint of the panel offers a clean high profile appearance. No more barn like metal building looks.

Robertson Buildings are Lightweight, yet very strong and durable attributing to reduced costs for erection and structural support.

Notes:

  1. Allowable positive load is the lowest value of the panel bending and shear strength or deflection limit.
  2. Allowable suction load is the lowest value of the panel bending and shear strength, deflection limited and
    connection strength for each fastener pattern. The numbers have been reduced to reflect the lowest value.
  3. Loads based on panel stress, deflection and connection design criteria are derived from ASTM E-72 testing.
  4. Allowable loads are calculated with a factor of safety of 2.5 for bending, 3.0 for shear and 2.0 for connection.
  5. Pattern FP1 is based on clip with (2) 1/4″-14 Tek III’s in minimum 14 gage steel.
  6. Pattern FP11 is based on five (7.2″ on center, low cell of product), 1/4-14″ Tek III’s with 5/8″
    neoprene bonded washer in minmum 14 gage steel.
  7. The structural capacity of the girs are not considered and must be examined independently.

Panel Thickness Includes Rib Height

Notes:

  1. Allowable positive load is the lowest value of the panel bending and shear strength or deflection limit.
  2. Allowable suction load is the lowest value of the panel bending and shear strength, deflection limited and connection strength for each fastener pattern. The numbers have been reduced to reflect the lowest value.
  3. Loads based on panel stress, deflection and connection design criteria are derived from ASTM E-72 testing.
  4. Allowable loads are calculated with a factor of safety of 2.5 for bending, 3.0 for shear and 2.0 for connection.
  5. Pattern FP1 is based on clip with (2) 1/4″-14 Tek III’s in minimum 14 gage steel.
  6. Pattern FP11 is based on five (7.2″ on center, low cell of product), 1/4-14″ Tek III’s with 5/8″ neoprene bonded washer in minmum 14 gage steel.
  7. The structural capacity of the girs are not considered and must be examined independently.
