Josh Flagg likes setting records. Within the first four years of his career, Josh participated in four record sales, three of which were in Beverly Hills. He grew up on the Westside and graduated from Beverly Hills High School in 2004, jumping right into high-end residential real estate. Josh had the choice to either join the family business, which owns and develops shopping centers, or go a different direction. He chose a different direction Josh is also one of the stars of Bravo TV’s Million Dollar Listing

“He pampers his clients…” said one local Realtor, “In a way I have never seen beforeand I’ve been in the business for 25 years. I’ve seen Josh send chauffeured cars to his clients’ homes and send his clients up in helicopters to view properties. The best thing I have seen Josh do, though, was wrap an entire house in a big red bow before delivering the keys to the new owners. He is very creative, and that is why he is so successful. In Josh’s mind, there are no limitations.” 

 

Introducing LoĒ-366 Glass for windows

Double-pane windows become triple-pane performers

Introducing Loå-i89™, our new energy-saving 4th surface coated glass. It offers more light transmittance and less reflectance than Loå-i81. And it’s now available in annealed making it less expensive. Yet it still delivers a center of glass U-Factor of just 0.20 when coupled with our Loå³ or Loå² glass and argon fill in a double-pane unit.

"The advantages are more than clear."

Meets today’s strictest energy efficiency guidelines.

With a center of glass U-Factor of only 0.20 (0.23 without argon) and SHGC of just 0.25, an insulating glass unit with Loå³-366 and Loå-i89 meets the most stringent energy standards – without going to a triple-pane unit. This allows you to offer more double-pane window options that can meet the proposed ENERGY STAR guidelines everywhere in the country.

Our enhanced performance glass …is even more enhanced.

There’s no need to go to triple-pane windows to meet the various energy-saving guidelines. No need to invest in redesigning your windows and altering your manufacturing processes either. A double-pane IG unit with LoĒ-i89 can meet the guidelines.

Read a Review of Gravina’s Window Center

Great people to work with.  We recently did a full frame replacement of all the windows in our home with Infinity from Marvin Ultrex Fiberglass windows.  The windows are wonderful, the installation was  efficient and well done and the final finish (stained) was nicely done.  Gravina’s Window Center was recommended to us by friends and we can easily recommend to others. M & M, Littleton
