Foster® C.I. Wrap™ 30 Vapor Retarder Sheet Membrane



Vapor Retarder Sheet Membrane

Foster C.I. Wrap 30 is a 30 mil flexible vapor retarder sheet membrane. It is comprised of synthetic rubber modified asphalt laminated to a tough polymer film and a treated peel and stick release liner. It is available in 4" and 35.5" widths.

C.I. Wrap 30 is used to provide a moisture retarder and vapor retarder film over cold and cryogenic piping and equipment insulation. It may be used over thermal insulation including cellular glass, polyurethane, polyisocyanurate, polystyrene, rigid fiberglass and others.

C.I. Wrap 30 provides a factory controlled film thickness and fast, labor saving application. The membrane is elastomeric allowing for expansion and contraction of the insulation system. It is self-healing and forms a strong bond to the substrate and the sheet overlaps.

C.I. Wrap 30 has a Class 1 flame spread when tested by ASTM E-84.

LIMITATIONS
Apply below 125ºF (52ºC). Sheet should be stored at 70 ° F for at least 24 hours before applying in temperatures below 60 ° F. Keep rolls warm until used. See application guide for applying in temperatures below 50ºF (10ºC).

Not for use below grade in direct contact with the earth. If used below grade it must be jacketed.

Do not apply to damp, frosty or contaminated surfaces.

Membrane should not be left exposed to UV for more than 14 days. Cover with jacketing as specified. If jacketing is not to be applied for longer than 14 days, cover temporarily with black plastic sheeting.

Membrane is not to be used for banding or mechanical fastening. Standard fastening of insulation is required.

Over polystyrene insulation on exterior applications, the membrane should be jacketed immediately with a white or light reflective jacket. If left exposed to sun, C.I. Wrap 30's black color may heat up enough to melt insulation.

For application by skilled professionals only.
