WALTHAM, Mass. – SPRI, the association representing sheet membrane
and component suppliers to the commercial roofing industry, announced that
three of its roofing standards have been approved by the American National
Standards Institute (ANSI).
The three key standards
approved by ANSI include:
ANSI/SPRI RP-14 2010Wind Design Standard for Vegetative Roofing
Systems– produced in partnership with Green Roofs for Healthy
Cities; ANSI/SPRI/FM 4435-ES-1 2010Wind Design Standard for Edge Systems Used with Low Slope Roofing
Systems; and, ANSI/SPRI IA-1 2010Standard Field Test Procedure for Determining the Mechanical Uplift
Resistance of Insulation Adhesives over Various Substrates. All
three standards will be posted on SPRI’s website (www.spri.org)
and may be downloaded free of charge.
ANSI/SPRI RP-14 2010Wind Design Standard for Vegetative Roofing
Systems provides design
guidelines associated with wind uplift and stone scour; defines items such as
set backs from the edges of roofs in areas with high winds, use of wind erosion
mats, as well as edging details. There is also a discussion of the various
types of materials and their behavior under varying wind conditions.
ANSI/SPRI/FM 4435-ES-1 2010Wind Design Standard for Edge Systems Used
with Low Slope Roofing Systems provides the basic requirements
for wind-load resistance testing and design for roof-edge securement, flashing
systems and nailers. It also provides minimum fascia thicknesses that lead to
satisfactory flatness, and designs to minimize corrosion. It is intended for
use with the specifications and requirements of the manufacturers of the
specific roofing materials and the edge systems used in the roofing assembly,
excluding gutters. The latest revision to ES-1 combines the performance
requirements included in the current version of ES-1, and has been expanded to
include requirements addressed in FM4435.
ANSI/SPRI IA-1 2010Standard Field Test Procedure for
Determining the Mechanical Uplift Resistance of Insulation Adhesives over
Various Substrateswas developed to provide a uniform field
testing procedure for determining the suitability of using an insulation
adhesive for insulation or cover board attachment to a substrate. This standard
is intended primarily for situations when an existing roofing system is being
replaced or recovered and the general condition of the substrate is in doubt.
This procedure, however, is also applicable to new
construction. The uplift data obtained provides the roof system manufacturer,
adhesive manufacturer and design professional with pull resistance values that
will assist in verifying the suitability of the intended design. The standard
was first approved as an American National Standard in 2005. It has been
revised and has been re-approved by ANSI. For more information, visit www.spri.org.
