Flexible and low permeable vapor retardants for facing products

A vapor retarder material, comprising:

• a first face material;
• a second face material;
• a non-halogenated flame retardant;
• and an non-halogenated latex;
• wherein the non-halogenated flame retardant and the non-halogenated latex are both located between the first face material and the second face material.

A process for making a foil-scrim-kraft (“FSK”) or an all-service-jacket (“ASJ”) product, comprising:

• coating an inner surface of a first face material with a non-halogenated flame retardant adhesive composition;
• coating an inner surface of a second face material with said non-halogenated flame retardant adhesive composition;
• positioning a reinforcing scrim between the coated inner surface of the first face material and the coated inner surface of the second face material;
• combining the coated inner surface of the first face material with the coated inner surface of the second face material with the reinforcing scrim in between to form a combined layer structure;
• curing the non-halogenated flame retardant adhesive composition;
• winding the combined layer structure to form a finished roll of FSK or ASJ product.
