Form

|
| ||
| Your choices are... | |||
| Blanket | The blanket form of a vapor barrier are materials that are sold in a roll or batt. An example is fiberglass insulation with a foil face. | ||
| Coating | Coating form vapor barriers are materials that are sold in a liquid form and are applied after curing to create a vapor barrier. The barrier can be a paint, spray, or foam that comes in various materials. | ||
| Membrane/Sheeting | The membrane/sheeting form of vapor barrier is a solid, flexible material designed for building wraps, foundations, and other applications. | ||
| Rigid Board | Rigid board form vapor barriers are materials that are sold as a rigid board. An example is foam boards that are used for concrete/masonry applications. | ||
| Other | The vapor barrier form is other/specialty. | ||

Material

|
|
| ||
| Your choices are... | |||
| Aluminum | Aluminum is a bluish, silver-white, malleable, ductile, light trivalent, metallic element with good electrical and thermal conductivity, high reflectivity, and resistance to oxidation. | ||
| Asphalt Emulsion | Asphalt emulsions contain up to 70% asphalt and typically less than 1.5% chemical additives. | ||
| Polyethylene | Polyethylene is a semi-crystalline (typically around 50%), whitish, semi-opaque commodity thermoplastic that is soft, flexible and tough—even at low temperatures—with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance, but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water. | ||
| Polypropylene | Polypropylene is a thermoplastic material exhibiting excellent cold flow, bi-axial strength, and yield elongation properties. It is similar to PVC, but can be used in exposed applications because of its resistance to UV, weathering, and ozone. | ||
| Rubber | Rubber is an elastomer that can be mixed with other materials to create a synthetic rubber. | ||
| Other | Material is specialty/other type. | ||

|
|
| ||
| Your choices are... | |||
| Attics | An attic is a space found directly below the pitched roof of a house or building. | ||
| Brick and Pavers | A brick is a block of ceramic material that can be used in many applications. Pavers are pre-cast pieces of concrete or brick used in landscaping applications. | ||
| Building Wrap | A building wrap is made from different types of material and are designed to surround an entire buildings exterior. | ||
| Concrete | Concrete is a material used in construction that is composed of cement and other aggregates to strengthen the concrete. | ||
| Crawl Spaces | A crawl space is a type of basement that allows access to plumbing, electrical, and ventilation with a height much less than an average basement. | ||
| Ducting | Ducts are used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air from areas. | ||
| Floors | Floors are walking surfaces that are constructed of many different types of materials. | ||
| Foundations | Foundations are usually concrete forms that are used to anchor/support a structure to and from the ground. | ||
| Piping | Piping refers to a system of pipes that moves fluids from one location to another. | ||
| Stone (Granite) | Granite is a type of stone/rock that is used in applications such as countertops. | ||
| Tile & Grout | Tile is a ceramic that is used in flooring. Grout is used to fill voids and seal joints between tiles. | ||
| Walls | Walls are solid structures that are used to support roofs and ceilings. | ||
| Windows | Windows are transparent openings that allow the passage of light into rooms. | ||
