In 1990, the opportunity to expand capacity for OEM work was pursued and Ciba-Geigy moved Heath Tecna's manufacuring operations to a new facility in Bellingham, Washington. In that same year, the company delivered over 200 shipsets of the Dash 8 interior to de Havilland Canada (a Boeing owned company at the time). By 1991, Heath Tecna supplied Boeing with over 1000 combined shipsets of the ATI (Advanced Technology Interiors) overhead stowage bin for B737s and B757s. Then finally in 1994, the majority of the engineering staff still located in Kent,  were relocated to the Bellingham facilities.

Starting in 1995, unique designs were being developed to take the company to the next level in the retrofit market. Heath Tecna was the first to invent and patent an innovative product called the bin extension. Installation of a complete shipset kit could be performed overnight, and when installed, the system would update the aesthetics of the interior while making the existing bins deeper. In the case of their most successful bin extension, called the ATIX (ATIX 1 shown above), passengers were able to stow roller bags transversely in the bin for the first time. So instead of just stowing two bags longitudinally, a bin could be modified overnight to hold four bags. The concept revolutionized the interior retrofit market and Heath Tecna installed hundreds of bin extension kits.

By 1996, Heath Tecna's ownership changed hands again. Hexcel Corporation merged with Ciba-Geigy and the Heath Tecna business was rebranded as Hexcel Interiors. Towards the end of the 90s, Hexcel Interiors began branching out into integration and reconfiguration programs. The list of capabilities continued to grow, and the company was evolving into a one-stop shop for customers.
