Do you remember back in the 70’s when there was a fad of putting shrink wrap over windows? Seems the technology has made significant leaps in improvement and may now be a potential method to allow homeowners to put off having to do a major window retrofit!

You may not need to do that window retrofit. A new California building code underscores the benefits of using ever-so-humble window film.
Faced with the second-highest total energy usage in the country (Texas is first), California has become the first state to recognize window film as bona fide energy-efficient (http://www.houselogic.com/green-living/saving-energy/) building materials.
By adding them to its state building codes (http://www.reedconstructiondata.com/building-codes/), California will require window films to meet certain criteria, similar to windows and roofing (http://www.houselogic.com/maintenance-repair/preventative-home-maintenance/roofing-gutters-siding/). Window films must:
•Carry a certification label from the National Fenestration Rating Council (http://www.nfrc.org/) (NFRC)
•Include the manufacturer’s name
•Have a 10-year warranty
•Be in compliance with the visual quality standards set by the International Window Film Association (http://www.iwfa.com/Home.aspx) (IWFA)
The new codes take effect in January 2014.
If you don’t know much about window films, they’re worth checking out. Different types can:
•Cut UV exposure (preventing your fabrics from fading)
•Strengthen glass for added security (http://www.houselogic.com/protect-your-home/home-security/)
•Create privacy (http://www.houselogic.com/home-topics/home-privacy/)
They’re relatively inexpensive, running $1.50 to $8 per square foot, and they’re a good DIY project (http://www.houselogic.com/home-topics/do-it-yourself/).
And they save energy (http://www.houselogic.com/home-advice/windows-doors/save-money-energy-efficient-window-coverings/). Some reduce radiant heat transfer through glass by as much as 50%, making them good choices for colder climes. Others block sunlight – great for west-facing windows and homes in sunny regions, such as the Southwest.
Window films are smart for retrofitting, too. Instead of swapping out older windows for new ones at $700 a pop, you can install a top-of-the-line film (and maybe a little weatherstripping) on your existing windows and get virtually the same benefits for $150.
Plus, you’ll help reduce waste when you keep used building materials (those older windows) out of the landfill.
So which would you rather have? New replacement windows or window films?
