product-ls36

  • Description
  • Advantages & Attributes
  • CF Roof – Material Specifications
  • Load Span Tables

The LS-36™ insulated metal roof and wall panel is versatile, offering many design options. The overlapping, through fastened joint allows for quick installation in roof or wall applications that results in reduced labor costs and earlier business starts. Owners will also appreciate the energy cost savings that an insulated metal panel provides.

Superior Insulating Value across the entire wall and roof area is assured with Robertson 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.

Insulated metal panels are Lightweight, yet very strong and durable attributing to reduced costs for erection and structural support.

  1. Live/Press: Allowable loads applicable to downloads such as roof live, snow, and positive wind pressure.
  2. Allowable values are based on a 36″ wide panel with a 26 Ga. fascia and 26 Ga. liner with 3-1/4″-14 SDS in a 3′ wide panel at each supporting structural member.
  3. Connection for Walls: Screws located at the middle of the low pan centered between the high ribs of the fascia panel. Attach fascia sidelaps with 1/4″ Lap Teks at 24″ o.c. max. spacing between main panel connections.
  4. Connection for Roof: Screws located at the middle of the high ribs of the fascia panel with an HW-355 bonded washer under the screw head. Attach fascia sidelaps with 1/4″ Lap Teks at 18″ o.c. max. spacing between main panel connections.
  5. Pullout of the self-drilling screws from the supporting structural member must be checked separately.
  6. Allowable values have been derived from tests conducted in accordance with the ASTM E72 and ASTM E1592 test specifications.
  7. Allowable face buckling, shear, and panel pullover loads have been calculated using a 1.875 safety factor derived from test data scatter.
  8. Allowable values include a deflection check against an L/240 limit for Live/Press loading, and an L/240 limit for 10-year wind pressures for Wind Suction loading.
  9. Allowable values shown are intended to be compared against factored loads from ASCE 7-based load combinations.
  10. Allowable loads are given for equally-spaced supports.
