What Our Clients Say

We began working with SHIELDS in the fall of 2010, after several failed attempts with other potential vendors, at developing a windshield for our electric utility vehicle, the Firefly ESV. Other suppliers were not able to achieve satisfactory clarity of consistent shape with the radical curvature and size windshield that we needed. Not only has SHIELDS surpassed all our design specifications, they also developed a frit (border) application process (saving us labor cost), provided their SUPERCOAT coating which exceeds our scratch resistance requirements, and constantly delivers a quality product on time. Working with SHIELDS has been a distinct pleasure, and we wish all of our suppliers could perform as they do; they are a quality group of people!

James Emmons, President/CEO, Firefly ESV

After almost 10 years with Shields, service has been nothing but excellent. Not only are they a vendor to Intercontinental Trophy Cup but they have also become close personal friends. What sets them apart from other manufacturers is their eagerness to take on dynamic and different projects when others choose to stay inside the box. They have provided windshields, stock glass replacements, and trophies for us over the years and we look forward to continuing the relationship with our new racing series.

Dougie Livingston, Series Principal, Intercontinental Trophy Cup

Sandra Gawlik, Senior Buyer, Purchasing, Alamo Group Inc.

We have used SHIELDS Windscreens on our award winning offshore catamaran line for many years and now on our latest Center console line. SHIELDS has produced a product that can withstand the punishing environment of performance boating. We are also pleased with the customer support and knowledgeable staff that serves us well, meeting very demanding timing and design needs. I would freely recommend SHIELDS as a great source for all your windscreen needs.

Randy Scism, Owner, Marine Technology, Inc.

Our company wishes to give special recognition to SHIELDS for being a first class supplier for replacement tractor windows and doors that we install on our product line. We have found their product to be excellent in quality and they are very reliable in delivery time. They have also been helpful in supplying one of a kind applications. We shall be glad to recommend them at any time.

Roger Chambers, President, Chambers American Products, Inc.

SHIELDS Windshields was able to help us with a Thin Trapezoidal Part that had several facets on the edges. This was a difficult part and they produced it reliably from lot to lot with excellent quality. Deliveries were on time and communication was Top Notch!
