AIR BARRIER DESIGN COMPATIBILITY: *The Air Barrier Association of America (ABAA) uses 75 Pascals as the pressure level at which to measure permeability of an air barrier component, assembly or the entire building. The ABAA allows compliance with their recommended permeability limits in ANY of three ways. SEISMIC COLORSEAL complies in ALL three ways: ABAA COMPLIANCE ALTERNATIVE: a) Materials: (0.02
L/s.m2 @ 75 Pa) b) Assemblies: (0.2 L/s.m2 @ 75 Pa) c) The entire building: (2.0 L/s.m2 @ 75
Pa) Bottom Line: SEISMIC COLORSEAL as a component by itself or measured as part of either a wall assembly or the entire building will not compromise the permeability of the entire air barrier assembly designed for the building. |

HURRICANE WINDS **Miami-Dade County Florida (the toughest standard for hurricane building code) requires windows tested to 150 mph winds. SEISMIC COLORSEAL has been tested to 200 mph.
The Saffir-Simpson Hurricane Scale is a
rating from 1 - 5 based on the hurricanes intensity. Wind
speed is the determining factor in the scale and winds are measured
using a one-minute average:
SEISMIC COLORSEAL has been tested to 200 mph positive and negative wind loading with essentially no (1/2 of a mm) deflection of the product either way. In addition SEISMIC COLORSEAL has been tested to 200mph wind-driven rain with no leakage. |

Expansion Joint Resists Hurricane-Force Winds & Water--and Has Air Permeability 2 1/2-Times Lower Than ABAA Requirements
--Testing SEISMIC COLORSEAL to ASTM E-283, E-330, and E-331
EMSEAL’s SEISMIC COLORSEAL has proved itself a workhorse in the sealing of building expansion joints in virtually any substrate material or building design.
Particularly in curtain walls but relevant to any wall the ASTM tests E-283, E330, and E331 define the performance ability of a wall assembly in regard to air leakage, water penetration, and static air pressure difference.
All wall and window assemblies contain joints--either to seal the assembly to the rest of the wall or to seal movement joints within the assembly.
It makes sense then to have data on how the building sealant or expansion joint material that will seal these penetrations will perform.
Why not test the expansion joint sealant to the same three tests?
The results would provide performance data that ensures that the sealant does not compromise the performance of the wall assembly.
20 years ago, EMSEAL applied this standard to its precompressed joint sealants COLORSEAL and BACKERSEAL.
We have recently had an independent laboratory run the same tests on SEISMIC COLORSEAL.
In short, SEISMIC COLORSEAL:
1) Has air permeability that is 2 1/2-times lower than the required by ABAA (ASTM E-283-04)
2) Shows no water leakage at well beyond hurricane force, wind driven rain--500, 1000, or 5000 Pascals (ASTM E331-00 (2009)
3) Resists well-beyond hurricane-force wind loading with essentially no deflection at both positive and negative pressures up to 4954 Pascals--equal to 200 mph winds (ASTM E330-02-procedure A)

Proposal No.: 09-006-7677
Date: November 12, 2009
1.0 INTRODUCTION
At the request of Emseal Corporation, Exova was retained to conduct a performance evaluation of the air leakage resistance, water penetration resistance and the structural performance properties of a specimen identified as “Seismic Colorseal (2")” expansion joint material as outlined in Exova Proposal Number 09-006-7677.
Upon receipt, the specimen was assigned the following Exova Specimen Number:
Client Specimen Description Exova Specimen No.
Seismic Colorseal (2" Thickness) 09-06-M0379
2.0 PROCEDURE
| Test Description | Test Method |
| Standard Test Method for Determining Rate of Air Leakage Through Exterior Windows, Curtain Walls, and Doors Under Specified Pressure Differences Across the Specimen | ASTM E283-04 |
| Standard Test Method for Water Penetration of Exterior Windows, Skylights, Doors, and Curtain Walls by Uniform Static Air Pressure Difference | ASTM E331-00(2009) |
| Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylights and Curtain Walls by Uniform Static Air Pressure Difference | ASTM E330-02 (Procedure A) |
Testing Outline:
As outlined in Exova proposal number 09-006-7677, a steel test fixture was constructed which comprised of a 51 mm (wide) x 152 mm (deep) x 1000 mm (long) gap for the installation of the specimen. A fabrication detail of the test fixture is located in Figure 1.
The expansion joint material (Exova Specimen: 09-06-M0379) was installed in the test fixture’s gap by a representative from Emseal at Exova’s Mississauga testing facility on November 2, 2009. Photographs of the specimen’s installation are located in Appendix A.
Upon installation, the specimen was allowed to cure in the test fixture for five (5) days at ambient laboratory conditions prior to any testing.
Testing was conducted on November 9, 2009 and the following testing protocol was requested by Emseal:
i. Initial air leakage measurements taken at 25, 50, 75,
100, 150, 250 & 300 Pa (ASTM E238); Infiltration case.
ii. Water penetration resistance at 500 & 1000 Pa (ASTM E331)
iii. Structural performance testing at ±500, ±1213, ±2730, ±4854 Pa (ASTM
E330-02)
iv. Water penetration resistance at 5000 Pa (ASTM E331)
