The primary seal is polyisobutylene (PIB), the most effective barrier to moisture vapor and water. Our secondary seal consists of polysulfide for conventionally glazed applications, or silicone for structural-glazed applications.

Insulated glazing may be framed in a sash or frame or in a curtain wall. IGUs are also commonly used for replacement windows.

AGI offers a number of glass options such as clear, tinted and Low-E to name a few. In addition to glass options we also produce IGUs with muntins. Muntins are available in a variety of colors.

What sets AGI apart from its' competition is that our IGUs are meticulously fabricated and they are clearned prior to leaving the shop so that they are ready to install when they arrive to our customers. Because we use a high grade PIB you will never have that sticky and tacky feeling on the outside of the unit after it is dry. To view our warranty, click on the link below.
