MOTORIZED SCREEN COMPARISON GUIDE
Magnetic vs. Spring vs. Zipper Screens: Which Screen Type Is Best for Colorado?
Not all motorized outdoor screens are built the same. The technology inside the side track, magnetic, spring, or zipper, decides how well your screens hold up to Colorado wind and how often they jam or need service. Here's how the three compare.
The Short Answer
Zipper systems hold the screen edge in a fixed track with a zipper-style edge, the most basic and jam-prone design. Spring systems use mechanical compression to hold tension, better than zipper but the springs fatigue over time. Magnetic systems like the MagnaTrack screens OSC installs use a free-floating track held by strong neodymium magnets that flexes under wind and self-corrects, eliminating the vast majority of common service issues. For Colorado's wind and weather, magnetic is the most durable and reliable of the three.
When you're investing in motorized screens, the fabric and motor get most of the attention, but the real difference in long-term performance comes down to how the screen is held in its side track. That single engineering choice determines how the system handles wind, how often it jams, and how long it lasts.
The Three Screen Technologie
Zipper Track Systems
Zipper systems use a zipper-style edge that runs in a fixed channel to keep the screen in place. It's the most basic retention method. The weakness is that the edge is locked into a rigid track, so when wind pushes the screen, that force concentrates along the fabric edge and the fasteners. Many zipper systems also have a real vulnerability: damage one zipper tooth, say by walking into the screen, and it can compromise the whole screen. They tend to be the most prone to jamming and wear of the three.
Spring Track Systems
Spring systems improve on zipper by using mechanical compression to create side tension, the spring pushes outward against the screen edge to hold it in the track. This gives better retention than a basic zipper edge. The catch is that springs are mechanical parts that fatigue. Every open-and-close cycle gradually changes the spring's tension, and like zipper systems, a spring track holds the screen rigidly, so wind load still transfers into the fabric and hardware rather than being absorbed. Spring force is also relatively light, averaging only around 3 to 5 pounds.
Magnetic Track Systems (MagnaTrack)
Magnetic systems take a different approach. OSC installs MagnaTrack motorized screens by Progressive Screens, which use a free-floating inner track held in place by strong rare-earth neodymium magnets, no zippers, no springs. Each magnet set delivers around 75 pounds of pulling force, averaging roughly 375 pounds per track, far more than a spring's few pounds. Crucially, the magnetic track is designed to flex and move with pressure rather than resist it: when wind pushes the screen, the track self-adjusts and distributes the stress instead of concentrating it, then self-corrects back into alignment. Progressive Screens reports this design eliminates about 98% of the service issues common to fixed-track and zipper systems.
Side-by-Side Comparison
Why This Matters in Colorado
Colorado's wind is the deciding factor. Along the Front Range, gusts and sudden storms put real force on any exterior screen, and that's exactly where the retention technology earns its keep. A rigid zipper or spring track fights the wind, and because it holds the screen in a fixed position, that pressure has nowhere to go but into the fabric edge, the welds, and the fasteners, which is what leads to tears, pull-outs, and track failures over time.
A magnetic track is engineered to do the opposite. Because the inner track floats on magnetic tension, it flexes when the wind pushes and then snaps back into alignment, absorbing and redistributing the energy instead of concentrating it. For large patio openings and exposed Colorado yards, that difference translates directly into fewer service calls, longer screen life, and screens that keep working through the conditions that cause lesser systems to fail.
