Dealers, manufacturers and localities nationwide are preparing for National Window Film Day, to be held tomorrow, April 30.

In addition to Virginia and St. Petersburg, Fla., the city of Chicago, Fort Myers, Fla., Henry County, Va., (home to Eastman’s film manufacturing plants) and Hawaii have all made proclamations that April 30 be recognized as National Window Film Day.

Tommy Silva being presented with Hawaii’s National Window Film Day proclamation.

“Window film is installed by hundreds of small businesses in the state of Hawaii,” says Governor David Ige. “[It offers] significant economic benefits at all levels—from employment to energy savings to improved health to the reduction of outdated glass in our landfills.”

Hawaii’s proclamation was presented to Tommy Silva, CEO of T&T Tinting Specialists, which released a video offering 20 percent off an installation in honor of the day.

Also arming consumers with information will be the International Window Film Association (IWFA), which will host a live chat on twitter on the use of window film. According to a press release, from 2:00 – 2:30 p.m. EST, consumers are invited to use and follow the hashtag #WindowFilmDay “for answers and insights into making their home more comfortable and more protected from UV damage.”

Tune in with your #windowfilm questions Thurs. 4/30 @ 2pm EST and remember to tweet using #WindowFilmDay!
