Sealtite™ The Most Complete Line of Pre-compressed Sealants
Sealtite Airstop FR
is a flexible, compressible, open
cell polyurethane foam with at least 80% open cell structure. Material is
designed to provide sound control characteristics in a wide range of
applications. Sealtite Airstop FR is ideal for use as an air infiltration
barrier in stationary or moving joints, such as those in curtain wall to masonry
studs plates to concrete slabs. Material can be coated with a neoprene coating
for use in high wear or exposed applications. Sound joints with 100% movement
capability may be constructed by gluing Sealtite Airstop to both side walls of a
Typical ApplicationsGenerally used
for filling, sealing, and insulating of joints, cracks, and cavities. Examples include the following:
Structural space between window and door frames
Seams between chimneys, roof protection, roof panels, and wall panels
Through penetrations around cables and pipes
Elongation must be at least 325% with a tensile strength of not less than 53 psi.
Material must provide a minimum of 25 dB reduction in noise and transference.
Material must be compressible to 10% of original thickness when compressed in one dimension.
Must not bleed, stain, or degrade beyond use under exposure to
10-year ultraviolet simulation by Weatherometer. (ASTM G53)
Joint faces shall be smooth and free of loose debris prior to application of Sealtite
AirStop. Material shall be a minimum of two times the width of the predicted
maximum joint opening. When used in conjunction with adhesive, Sealtite
Flexible Seal or Gel-Loc 25 is required. When used as a waterstop in conjunction
with polyurethane grout, consult the respective manufacturer for installation procedures.
