Solar Innovations, Inc. plans to release a new sliding door system that will separate us from our competitors. The SI8600 sliding door system will work in both dual track and multi-track configurations, allowing receipt of up to 1½” insulated glass units. This allows the pursuit of jobs with high STC (sound transmission class) requirements. This system will also have excellent thermal performance due to its thermal break design. The ramped sill design should also perform well for water when vented properly.
