Commercial Roofing Insulation Board: 


ARDEX Polyiso Insulation Closed-cell PIR Foam Insulation Board 

ARDEX POLYISO flat board roofing insulation consists of a closed-cell polyiso foam core laminated to black glass reinforced mat facer on both surfaces. ARDEX POLYISO insulation provides outstanding thermal performance on commercial roofing applications.

All ARDEX POLYISO insulation boards incorporate a HCFC-free blowing agent that does not contribute to the depletion of the ozone (ODP-free).

The ARDEX POLYISO is suitable for adhered, ballasted and mechanically fastened single-ply roofing systems. It provides outstanding thermal resistance, dimensional and compressive strength. 

FEATURES and BENEFITS

  • Compatible with ballasted, fully adhered, and mechanically attached single-ply systems
  • Available in flat boards of 1.22m x 2.25m and in thicknesses ranging from 25.4mm to 101.6mm.
  • Provides outstanding thermal resistance, dimensional and compressive strength
  • Compatible with ARDEX recommended water based bonding adhesives
  • ARDEX TPO roofing systems installed over ARDEX POLYISO obtain BROOF(t1) fire rating  

R-values have been determined using the calculation method described in EN ISO 6946 standard based on the use of the ARDEX ISO 95+ insulation board waterproofed using a single-ply membrane and taking into account the surface resistances, both inside and outside.

If you require a more detailed R or U-value calculation, please contact the ARDEX Technical Department.

Code Compliance

ARDEX POLYISO bears a variety of code body compliances noted below:

  • CE marked according to EN 13165
  • ASTM C-1289, Type II, Class 1
  • UL Classified
  • FM Class 1 Approved (insulated steel deck construction)
  • Manufactured in an ISO 9002 Registered Facility  

Packaging, storage and precautions

  1. Tuff-wrap packaging provides a durable protective covering to the top and four sides of the bundle, as well as a portion of the bottom board.
  2. Keep insulation dry at all times. Insulation bundles need to be elevated above the water line to prevent moisture infiltration from the bottom side.
  3. Combustible. Refer to MSDS for more information.
  4. Before insulation is placed on the roof deck, the substrate must be clean, dry, free of debris, water, ice or snow, and suitably prepared by removing all defects that might affect the quality of the application. Any unusual deck conditions or defects should be brought to the architect or building owner’s attention prior to installation.
  5. No more insulation shall be installed than can be covered with membrane and completed before the end of each day's work or before the onset of inclement weather.
  6. ARDEX POLYISO is non-structural, non-load-bearing material. The finished roof assembly should be protected from excessive roof traffic with proper walkway materials.  

Method of application

ARDEX POLYISO insulation boards must be installed using fasteners and plates, hot bitumen or ARDEX approved insulation adhesives. Insulation shall be neatly fitted to all roof perimeters, penetrations and abutments. The ARDEX POLYISO board is suitable for adhered, ballasted and mechanically fastened single-ply roofing systems.

Mechanical attached single-ply systems Fasten the insulation with a minimum of 5 approved fasteners and plates per 1.22m x 2.25m board. Additional fasteners may be required in areas of high wind loads or around the perimeter of the roof. Please refer to local wind uplift requirements and/or contact the ARDEX Technical Department.

Ballasted single-ply systems For ballasted systems, the top layer of ARDEX insulation may be loose laid or adhered. If mechanical attachment is specified, contact ARDEX Building Products for specific guidelines.  

Fully adhered single-ply systems Number of fasteners per board needs to be determined based on a wind uplift calculation in accordance with local building codes and taking into account the following minimum requirements:

  • Thicknesses less than 38.1 mm: Fasten insulation with minimum 16 fasteners per 1.22m x 2.25m board.
  • Thicknesses less than 50.8 mm: Fasten insulation with minimum 12 fasteners per 1.22m x 2.25m board.
  • Thicknesses less than 101.4 mm: Fasten insulation with minimum 8 fasteners per 1.22m x 2.25m board.
