Air Barrier / Vapor Barrier

Spray Foam Air Barrier

Using spray foam to get a air seal on commercial, residential, and industrial will be crucial. Using foam as an air barrier will not only create an air and vapor barrier it will also create a seem less insulation system.

Air Barrier

What is an air barrier? The new codes call for an air barrier on all the future projects so whether it is residential, commercial, or even industrial. Air barriers are a complete seal of the building envelope. This means all seams in the building system will have to be sealed. The reason spray foam works as the very best air seal is due to two factors. First it is liquid applied. This means that if applied by professionals it will be sprayed onto every part of the substrate gluing and embedding itself into each and every imperfection. Second is the expansion, Once on the substrate it will form around anything that come through the substrate thus insuring that the air on the exterior stays on the exterior.

With every build there are different challenges that we will face. With over 4 decades in the air barrier field we are able to draw on the things we have learned in the past to ensure that your project is done effectively and efficiently as possible.

Air Barriers In Construction

Every project should have an air barrier plan. From residential air barriers to industrial and commercial, there should be a way to ensure that air that is meant to stay out will stay out.

By spraying foam in place of using other air barrier methods the entire building can be sealed using the same material that is insulating the building.  With multiple different types of foam it can be applied on the interior or exterior. It also can be applied on all construction substrates with no preparation needed. Using either high and low density any project can receive the proper seal whether on residential, commercial or industrial. We will help find you the most effective system for your needs.

Vapor Barrier

A vapor barrier on the exterior substrate. In the past a exterior vapor barrier has been applied to a building that in will have a brick veneer. This is done by applying the spray foam after the framing or block wall has been installed with the hangers. After this is done foam will be applied with the before the veneer. In the past this has been mainly done with brick veneers. This system could also work with any type of siding. The spray foam can act as a air/vapor barrier along side of the insulation. This would mean that an entire building with have a continuous envelope thus ensuring that neither vapor or air could penetrate into the living/working areas.

Decrease Liability

As an architect, you’re liable for the building you design. With a 3/4″ by 3/4″ air leak in your siding, as much as 7.92 gallons of water can penetrate your building within a year. This can damage the integrity of the structure. With this in mind it is imperative to use the best air barrier. Spray foam can be applied to all substrates found in building construction making it easy to implement. On top of this it can be applied from the exterior as well as from the interior making it easy to use with every design.
