Below is a testimonial from Boban M who lives on Burke Mtn.
" When i first moved to Burke 5 years ago... i was literally scorching in our home because of all the south facing windows. Had to spend a fortune on A/C machines and had them cranked all the time for the entire summer. I complained to Al from Shatter Safe about the heat and for a relatively small amount of money Shatter Safe was able to install the UV film on the inside of the windows and it's literally been 3 years and i haven't had the A/C on since... " " Its the real deal... I think i only had my AC on once since and it was when it hit 98.6f (37c) and that was only in the upstairs bedroom"
