Ultrafab Extruded Seals (Ultra Cell / Multi Hollow Bulb / UCx)
TPV bulb and closed-cell foam window sash seals — Ultra Cell, Multi Hollow Bulb, and UCx profiles. AAMA 701/702-23 Class A rated.
Extruded bulb seals are ideal for applications that require frequent compression between the sash and the frame, delivering a reliable seal that springs back. The family covers three seal types: Ultra Cell microcellular closed-cell TPV foam, dual-bulb Multi Hollow Bulb, and general-purpose UCx with a TPV bulb on a coextruded polypropylene base.
All seals deliver excellent physical stability with superior adhesion between the TPV bulb and polypropylene base, industry-leading resistance to compression set, and minimal closing force.
