★★★★★
“Before partnering with Guardian Bastille, our campus struggled with extreme heat and glare issues that made large sections of the building uncomfortable for our employees. Their installation of 3M Prestige 40 completely transformed our workspace—dramatically improving comfort and reducing energy load without changing the building’s clean, modern appearance. It truly saved the day for our facility.”
