Insulated Glass Units
- We manufacture IGUs that are classified as “dual sealed.” The two seals are the primary and secondary. The primary seal is a poly-isobutylene material, also known as PIB or butyl. The secondary seal used will be either silicone or polyurethane. The size, shape, and make-up of the IGU will determine which type of secondary seal is used. Here are the guidelines that will determine which secondary seal will be used.

Aluminum and Glass Maintenance
- Solid Wall Panels – Clean with a soft, damp cloth and mild cleanser. Do not use abrasive cleaners.
- Aluminum Frames – Clean with a soft cloth and a dishwashing soap/water mixture. Do not clean with abrasive cleaners. Strong chemicals can damage aluminum.
- Glass Panels – Clean with a soft cloth and mild glass cleaner. When cleaning windows with glass cleaning ingredients containing ammonia, take caution, because the formula can mottle and pit the surface of the windows’ aluminum frames.
- Glass Marker Boards – Clean with a basic glass cleaner 2-3 times per week for heavy use.
