Air and Vapor Barrier Sealing Systems
Why is airtightness in buildings important?
Air barriers are essential for a high-performing building envelope. They dramatically improve building energy efficiency, indoor comfort, and longevity.
The airproofing layer protects the insulation from moisture and condensation from the inside, ensuring that the insulation works effectively and provides a healthy indoor living environment.
Jaeger USA's private label air, water, and vapor barrier sealing systems are made to industry standards and collaboration with your team allow personalization of your products for your brand.
What is an Air Barrier?
Air barriers are systems of materials designed and constructed to control airflow between a conditioned (indoor) space and an unconditioned (outdoor) space.
Air barriers can be mechanically fastened building wraps, adhesive membranes, fluid-applied materials, insulating board stock, non-insulating board stock, spray polyurethane foam, poured concrete, metal, glass, and a host of other materials.
Airtight homes, small businesses, and skyscrapers provide better indoor air quality because an effective air barrier blocks dust, pollen, smoke, and other outdoor pollutants.
In tight buildings, the ventilation system and not air leakage provides virtually all of the building's fresh air.
The airproofing layer protects the insulation from moisture and condensation from the inside, ensures that the insulation works effectively and provides a healthy indoor living environment.
What is a Vapor Barrier
Vapor barriers (or vapor retarders) are materials used to slow or reduce the movement of water vapor through a material. Vapor barrier materials are installed on the warm side of the insulation in a building assembly, as determined by climatic conditions. In warm climates, it will be on the exterior and in cold climates, it will be on the interior.
The thermal insulation separates the indoor from the outdoor climate. The temperature difference between the two climates attempts to become equalised through the flow of air.
This means in winter the warm air from the building transfers through the structural elements to the outside. The airproofing layer prevents this airflow, and therefore the loss of hot air to the outside.
The interior space is here not hermetically sealed off – like using a plastic bag – from the outside air. Instead, the exchange of air from the inside to the outside continues via diffusion.
If indoor air were to flow unrestricted through the thermal insulation, it would increasingly become cooler the farther it penetrates towards the outside until it finally emerges as condensation.
Condensation may cause considerable damage to the building and its components. Load-bearing structural elements may rot and lose their strength.
