Crystal Lake has schools and a community college, county offices, manufacturers and corporate offices, banks, medical and eye care offices, and stores and restaurants along Route 14, Randall Road and downtown. Their window problems are familiar ones: heat and glare in classrooms, atriums and offices, privacy in offices and patient areas, and security at entrances.
Every project starts on site. David Johnson, the owner, or one of our field technicians looks at the glass type, sun exposure, framing and how the space is used, and recommends the film that fits that building. Our own crews do the installation, and our headquarters is in nearby Elgin.
