StoGuard Offers Seamless Protection
StoGuard air barriers control air leakage through the building envelope, helping you achieve the most efficient building design possible. Sto membranes not only lower energy costs but provide a more comfortable, healthy indoor environment, guarding against mold and mildew damage.
The StoGuard Air Barrier Products
Unlike building wrap barriers punctured by staples and fasteners, StoGuard fluid-applied air barriers provide seamless protection for any climate or wall-design. Choose from:
- Sto AirSeal
This vapor-permeable membrane is roller or spray applied. It is ideal for use in above-grade walls behind various claddings such as concrete, brick masonry, CMUs, gypsum, cement board, exterior plywood, OSB, metal panels, stucco, wood/vinyl/cement siding, and more. Sto AirSeal is also recommended for use in conjunction with StoTherm ci Systems.
- Sto VaporSeal
Sto VaporSeal is a ready-mixed, flexible, vapor-impermeable membrane that is water-resistant. It can be roller or spray applied. It is ideal for use in vertical above-grade wall applications behind cladding, including brick, concrete, masonry, CMUs, OSB, exterior plywood, gypsum, cement board, metal panels, stucco, stone and brick veneer with a cavity, and more.
- Sto ExtraSeal
This vapor-permeable membrane is specifically designed for use beneath direct applied stucco brown coats. It is applied via spray or trowel to vertical above-grade concrete, brick masonry, and CMU wall surfaces.

- StoGuard Emerald Coat
Sto Guard Emerald Coat is a fluid-applied vapor-permeable flexible waterproof air barrier membrane. It is ideal for guarding against moisture damage from rain during construction, later offering protection in the event of a cladding breach. StoGuard Emerald Coat is recommended for use behind Portland cement stucco with metal lath and a slip sheet or building paper/felt, or as a sheathing as part of the StoGuard membrane system. Also compatible for use with concrete, masonry, and sheathed walls, and beneath wood/vinyl/cement siding and brick veneer with a cavity.
- Sto Gold Coat Air Barrier System
Sto Gold Coat is a fluid-applied vapor-permeable air barrier and water-resistive barrier with built-in antifreeze properties. Like StoGuard Emerald Coast, it protects against moisture damage from rain during construction, later offering protection in the event of a cladding breach. It is designed for use beneath the StoTherm ci Mineral Wall System. It is also compatible for use on prepared vertical above grade concrete, concrete masonry, brick masonry, wood/vinyl/cement siding, behind Portland cement stucco with metal lath and a slip sheet or building paper/felt, and brick veneer with a cavity.
