Boeing Museum of Flight – Tukwila, WA

Overview

The Boeing Museum of Flight is the largest independent, non-profit air and space museum in the world. It’s quickly gaining traction as a Seattle landmark. Housing over 175 aircraft and aviation exhibits, the museum offers a breathtaking look into our nation’s history of flight.

Scope

The Boeing Museum is essentially a gigantic glass hangar. When a building is made of glass, leaks can be a serious issue. The museum was no exception – it suffered from leaks since opening day due to poor sealant application. The project called for a full sealant replacement to stop the leaks.

Lacey Glass (Lacey, WA) was the installer for the project and Colorado Steel Sash provided product distribution. CSS is one of Pecora’s many trusted distributors; they supplied 3600 black sausages of Pecora 890NST and 5200 lineal ft. of Sil-Span. The material was applied to the entire building’s glass and aluminum structure. 

The deciding factor for specification was the strength of Pecora 890NST silicone sealant. According to Pecora Northwest rep Steve Swim, 890NST holds exceptional adhesion when applied to metal, with good bond and elongation. In this particular application, there was no need for priming.

Pecora 890NST does more than protect a structure from weathering. All buildings that utilize Pecora 890NST are safe from sealant staining and residue rundown that ruins the building aesthetic. Since the museum’s walls consist of glass panels, it will be looking crystal clear for years to come.

Pecora 890NST is a one-part, neutral-curing, ultra low-modulus silicone sealant. It reacts with atmospheric moisture to form a durable, flexible building sealant. Pecora 890NST performs exceptionally well under dynamic conditions.

Installers from Lacey Glass applied the product successfully. The application simply involved installing the sealant beads up and down the glass panel joints. The installers gave positive feedback about Pecora 890NST, praising its usability.

The museum itself, however, proved to be a slight challenge for the installers. The product was applied during the warmer months when the exterior temperatures of glass are elevated. As a result, the installers had to work around the weather, starting early in the morning and finishing by early afternoon.

Workers also couldn’t kneel on the glass, so they had to strenuously bend and twist their bodies to correctly apply the product.
