Duro-Last EPS Flute Fill Combo User Manual

DURO-GUARD® EPS FLUTE FILL COMBO

Description:

Duro-Guard insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS). It meets or exceeds the requirements of ASTM C 578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.

EPS Flute Fill Combo can be cut to fit virtually all types of steel deck and metal roof profiles, thus elimimating any need for a separate flute filler. It can be ordered with a polyester facer or fire rated (FR) coated-glass fiber mat facer.

Benefits:

 FR facer helps to achieve UL class A roof

assembly over noncombustible decks. Refer to UL listings for maximum incline.

 Both facer types eliminate the need for a

slip sheet.

 Shiplap joints help prevent thermal bridging.

 High thermal efficiency and maximum durability.

 Reduces inter-ply adhesive and saves labor.

 Provides long-term thermal insulation value.

 Does not contain CFCs or HCFCs.

 Superior moisture resistance.

 100% recyclable.

 Available in three densities per ASTM C 578:

o Type I, 1.00 pcf. o Type VIII, 1.25 pcf. o Type II, 1.50 pcf.

 Refer to Table 2 for physical properties.

Recommended Uses:

 Mechanically attached Duro-Last

 Duro-Bond

 Metal retrofit roof systems.

Refer to the appropriate installation specification for the above uses.

Flat Panels:

 Typical sizes:

o 4 ft. x 8 ft. (1,220 mm x 2,440 mm). o Thickness (overall): Up to 8 inches (203 mm). o Thickness (above top flute): 1-1/2 inches

(38 mm) minimum.

Installation:

 Duro-Guard EPS Flute Fill Combo may be

used directly under the Duro-Last membrane with either polyester or FR facer. Care should be taken to ensure that “bare” EPS is never in direct contact with the membrane. Refer to the appropriate Duro-Last specification for slip sheet and cover board requirements.

 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.

DURO-GUARD® EPS FLUTE FILL COMBO

 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.

Panel Attachment:

 Panels may be attached to the roof deck using

mechanical fasteners only.

Mechanical Attachment

 When installing multiple layers (which may

include insulation, cover boards and thermal barriers) it is acceptable to mechanically secure through all layers.

 Only use fasteners and plates supplied by, or

approved by, Duro-Last, Inc.

Storage:

 Insulation must be protected from open flame and

kept dry at all times.

 Factory applied packaging is intended only for

protection during transit. Slit or remove the packaging to prevent accumulation of condensation.

 Store elevated (at least 3 inches) and completely

covered with a weatherproof covering such as a tarpaulin.

 Do not use panels which are wet or damaged.

Limitations:

 Duro-Last, Inc. will not be responsible or liable for

any defects or problems related to building or roof design by others, to deficiencies in construction, to dangerous conditions on the job site, or to improper storage, handling or installation by others.
