Description:
Duro-Last®, Inc. specifies the use of concrete nails
for the mechanical fastening of the Duro-Last roofing
system on structural concrete decks. Duro-Last
Concrete Nails are Duro-Coated for protection against
the harsh roofing environment.
The concrete nails surpass the FM 4470 specification
and may be used to fasten both insulation and the
Duro-Last membrane to the deck.
Installation:
1. Duro-Last Concrete Nails are designed to be
installed into a pilot hole made by a 3/16-inch
(5 mm) masonry drill bit.
2. The depth of the pilot hole should be a minimum of
1.5 inch (38 mm).
3. Penetration into the concrete deck is 1 inch (25.4
mm), minimum, from the top surface of the deck.
4. A Duro-Last Plate is required for each fastener
used for membrane attachment.
Note:
•
Duro-Last, Inc. stocks concrete nails in the sizes
noted in the table to the right. Additional sizes
are available on a drop ship basis. Please allow
adequate time for ordering and delivery of special
orders.
