Weather Barriers

4specs has separated weather barriers into vapor resistive and vapor permeable barriers and into sheet applied and fluid applied systems.

Vapor Resistive Barriers

• Sheet Applied
• Fluid Applied

Vapor Permeable Barriers

• Sheet Applied
• Fluid Applied

In addition, 4specs classifies other vapor retarding systems into different groups by use methodology:

Concrete Admixtures/Additives - Vapor retarder products added to the concrete mix

Under-slab Vapor Retarder Membranes - Sheet membranes applied under the concrete slab

Vapor Control for Flooring - Materials applied over a completed slab to reduce vapor transmission, other than as a component of a fluid applied floor system.

Fluid Applied Flooring - For vapor retarding materials applied as part of the fluid applied flooring system.
