Unbelievable product. We wanted green technology. Low U Factor / Super insulating properties and sound dampening as our facilty is within two miles of a major airport and on the north approach flight path. Your proprietary Nano Insulgel – silica aerogel filled polycarbonate panels, does the job. These 55″ x 55″ aluminum double wall insulated, thermal break, skylights are beautiful and high performance. Thanks for a job well done Bristolite! We’ll be back on our next project!
