Solutions for Air Leakage in Buildings

Blog 28 Leak

With more people than ever concerned about implementing green building practices in commercial construction, making sure there are no air leaks in buildings (air leakage) is an important factor in construction planning. Here are some ways to make sure a building is tighter and more energy efficient.

When Air Leakage in Buildings Is Most Likely to Occur

During building construction, there are many points at which small gaps can be left that can lead to air leaks. Caulk and other sealants take a lot of time to apply so it is best to minimize leaks with a good air barrier in order to reduce the future use of other more hard-to-apply sealants. Taking this step will help avoid extra costs in labor as well as heating and cooling costs.

Air and Moisture Membranes

It is important that a building be able to let moisture vapor out but not let liquid water in. This is not hard to accomplish if the proper air and moisture membrane is used. Customers can drastically reduce heating and cooling costs by using moisture and air barrier membranes. This provides an added incentive for using a high quality barrier during construction.


The DELTA®-VENT SA membrane is highly permeable so that vapor is allowed out but surfaces are sealed from water and air intrusion. Since DELTA®-VENT SA is self-adhesive, it is very easy to install, so less labor is required. This can save your client a lot of money over the course of their construction project.

Cosella-Dorken can provide you with a wide range of vapor and air barriers. No matter how small or large your project, it is important that you take measures to control air and moisture leaks. When you do this, you are contributing to the longevity of the building and the comfort level of those that use the structure on a daily basis.
