 R-value of 2.5 is significantly higher than roof

cover boards made of wood fiber or gypsum.

 Lightweight (11 lbs. per 4 ft. x 8 ft. panel).

 Easy to cut, handle and install.

 Manufactured with a blowing agent that has

zero ozone depletion potential (ODP) and

virtually no global warming potential (GWP).

 Recycled content > 8%.

 Compressive Strength > 90 psi.

 4 pcf density provides enhanced physical

properties.

 Passes ASTM Resistance to Mold Test.

 Refer to Table 1 for physical properties.

Recommended Uses:

 Mechanically attached Duro-Last

roof

systems.

 Adhered/Fully Bonded Duro-Last roof systems.

Installation:

 In steel deck applications, Duro-Guard ISO HD

insulation or as recover board over an existing

roof. It may be placed directly on flute filler in a

metal roof retrofit application assuming the

flutes are completely filled.

 Panels must be kept dry before, during and

after installation. Install only as much insulation

as can be covered the same day with

completed roofing.

 The use of multiple layers of insulation with

joints staggered a minimum of 6 inches

between layers is recommended to eliminate

thermal bridging.

 Abut panel edges together and stagger joints of

adjacent panels.

 Boards must be neatly fitted to roof deck and

around penetrations with no gaps greater than

¼ inch.

 Refer to the appropriate Duro-Last roof system

specification and detail drawings for deck

preparation and attachment requirements.
