Galena Residence Huper Optik ESC 35 – The homeowner wanted to make energy efficient improvements to their Galena residence. Sierra Window tinting was called in to model the glass to determine the current energy efficiency versus a window film upgrade. Based on the client’s needs our recommendation was to install Huper Optik ESC 35 which increased the glass performance over 300! When the project was completed, over 100 sq ft of film was installed and the homeowner was delighted with the end result. So were we!
