Regular Solar Screens normally have 1 crossbar or none at all depending on the actual window. Your window will dictate the proper “crossbar” or lack thereof in order to give the screen the support it needs while keeping the full view through the window without seeing the solar screen’s support bar.

Operational windows will normally have 1 crossbar, usually horizontal, on windows that open. The bar is placed on the solar screen where the natural break of the window is. Some windows that open “side to side” will have a vertical bar at the natural break unless the window has a duel track system. Then there will be two individual solar screens made to fit in its tracks.

Non-operational windows, windows that do not open, will normally not have any cross bars to keep the full view out of the window. The window itself always dictates the proper amount of support bars needed and where they go

GRIDWORK Solar Screens


Our Custom Gridwork is where we match the panes in  your windows. giving your screen the mullioned look that matches your window. Or if you don't have panes in your glass, some of our customers add the Custom Gridwork to give their windows that appearance. Each section of our gridwork is blind riveted in the back, keeping it from sight but also securing and stabilizing your solar screen. Any gridwork that claims to be adjustable will also move out of place and therefore, easily damaged.  

Solar Screen Fabric

Vertishield Solar Sun screens

Although Lone Star Solar Screens offers all major brands of solar screening, we only offer top of the line PVC coated woven Polyester fabrics. No fiberglass is used in any of our exterior solar screening. Our products are available in 80% and 90% woven patterns. Available colors include: Beige, Black, Brown, Buffalo, Desert Sand (or Stucco – depending on the Brand), and Gray.

All of our solar screen products are the most energy efficient solar screening on the market today, excelling in durability as well as fade and mildew resistant. All of our solar screening fabrics have an antifungal additive that extends its mildew resistance and is environmentally safe for your entire family, including pets.

Again, Lone Star offers all major brands of solar screen, but its brand of choice is Vertishield, supplied by Vertilux.

Lone Star lent its expert experience along with its decades of knowledge, including feedback of its 100,000s of satisfied retail customers, its wholesale customers and other contractors on what the end users wanted and expected from a premier solar screen. Such as, family (including pets) safe, performance, durability, appearance and visibility. Lone Star also advised along with others the need to make the product more workable, making the rolling process as easy as possible while still retaining the stability, shape and durability with the least amount of defects possible. It also needed to be held to the same or surpass the standards as the other brands, Vertishield matched or exceeded these standards in every area. The low sheen, streak free finish allows for the ultimate in visibility all with an even color finish.

Our rivets guarantee that your grid-work will not become an eye sore by moving and creating double lines while looking out of your windows.We carry only .024 heavy gauge roll form aluminum frame, available in 5/16” x 3/4”, 5/16” x 1”, and 3/8” x 3/4”.  We have this frame especially made for us by the Manufacturer to our specifications.Available in 5 different colors: Mill, Bronze, White, Almond, and Champagne

Solar Screen Corners


We mainly use Solid External Corners made from Acrylonitrile-Butadiene-Stryene* (Description of ABS is below.)

These solid corners are guaranteed to never break, rot, or become brittle. Although a corner is one of the least expensive components to a solar screen, it is one of the most important to keep your solar screen structurally sound through the years.

Since the cut required for these corner pieces is a straight cut, it ensures a tight fit in each corner of the solar screens, allowing “Zero give,” guaranteeing that your solar screens will remain wrinkle free for as long as you live in your home. An interior metal corner requires an angle cut and will always allow “play” at the corner making it vulnerable to causing wrinkles. Although the interior metal corners are cheaper it is never a good idea to use them with a heavy polyester solar screen.

 *Acrylonitrile-Butadiene-Styrene, or ABS as it’s known in the industry, is a engineering plastic that is easy to machine and fabricate. ABS is characterized by resistance to chemicals, heat and impact. Typical applications for ABS include appliance housings, luggage, camera bodies, power tool housings, battery cases, tool boxes, packing crates, radio cases and various furniture components. ABS is an ideal material for structural applications when impact resistance, strength, and stiffness are required. It is widely used for machining pre-production prototypes since it has excellent dimensional stability and is easy to paint and glue. Natural (beige) ABS and black ABS are FDA compliant for use in food processing applications.

The following physical property information is based on typical values of the base acrylonitrile-butadiene-styrene resin.


 -Excellent impact resistance

-Good machinability

-Excellent aesthetic qualities

-Easy to paint and glue

-Good strength and stiffness

-Relatively low cost


-Machined prototypes

-Structural components

-Support blocks Housings



We only use serrated rubber spline. This long lasting spline is the same rubber material used on 50,000 mile tires and will stand up to the intense Texas Summer Heat. This spline will last for years and years.

The serrated spline catches under the J hook in the spline groove, ensuring the screen will remain secure in the track for years.
