Carlisle’s VapAir Seal 725TR Air

Carlisle’s VapAir Seal 725TR Air

Carlisle’s VapAir Seal 725TR Air and Vapor Barrier/Temporary Roof is a 
40-mil composite consisting of 35 mils of self-adhering rubberized asphalt 
laminated to a 5-mil woven polypropylene film. A one-piece silicone poly 
release liner is applied to the SBS adhesive to prevent the material from 
bonding to itself. VapAir Seal 725TR is available in a 325-square-foot 
roll with dimensions of 39" x 100'. The factory-controlled thickness of 
the membrane ensures uniform barrier properties on the job; the woven 
polypropylene film increases strength and has a non-skid surface suitable 
for the bonding of subsequent layers. Approved Carlisle adhesives for 
attaching insulation to VapAir Seal 725TR are:
» Flexible FAST™ Adhesive
» OlyBond 500™
VapAir Seal 725TR can be used on concrete, plywood, exterior gypsum, 
DensDeck® Prime, SECUROCK® or other approved substrates in 
conjunction with Carlisle SynTec roofing systems. Gypsum decks may 
require additional securement with mechanical fasteners. Use of CAV-
GRIP™ III Low-VOC Adhesive/Primer, CCW-702 or CCW-702LV is required 
on all substrates. VapAir Seal 725TR may be installed directly over a nailed 
Carlisle Modified Base Sheet when primed with CAV-GRIP III.
VapAir Seal 725TR must be covered with roofing membrane within 180 
days. T-joints must be sealed with an internal bead of Carlisle Lap Sealant. 
Carlisle does not accept responsibility for the watertight integrity of the 
VapAir Seal 725TR related to workmanship issues or physical damage.
