Which is Which?
One of these windscreens is brand new; the other is eight years old. The old screen was borrowed from a first customer, sold back in November of 1999 for a BMW Z3. The used windscreen has been in active use since. The customer estimate he drives top-down 140 days per year. He leaves the windscreen in the car about ten months a year, taking it out and storing it during the raining months of December and January. Can you tell which windscreen has a thousand days top-down use and 3000+ days mounted in the car, and which windscreen is brand new?
Comparing the strength of Windblox’s material, three patio bricks are placed across a 36 inch span upon materials used by other manufactures:
#1) This is a sheet of ordinary 1/4 inch (635 mm) acrylic. The deflection bottoms out, more than three inches (7.6 cm).; This is the windblocker material used by other vendors.
#2) This is a sheet of 3/8 inch (953 mm) of polycarbonate acrylic. Despite being thicker than Windblox, this wind deflector still deflects 50% more; the deflection is just over 1.5 inches (3.8 cm).
#3) Windblox’s material deflects less than 7/8 inch (2.2 cm) under the same weight.
Edging Cut The Right Way To Cut
#1) A customer traded in this particular windblocker, purchased from another vendor. This windscreen was fabricated upon a shop table router. The cut and workmanship is inconsistent, with nicks and gouges.
#2) This wind deflector was cut upon double sided AR Polycarbonate acrylic, using a CNC router. While the cut is smooth, machinery marks are prominent.
#3) Windblox’s windscreens are cut using a five thousand watt laser, ensuring a crystal clear cut with a polished finish.
A customer experienced this fracturing with a wind deflector purchased from another vendor. From the continual movement and stresses, combined with inferior material, micro-stress cracks emerged. These cracks grew over time, until the windscreen became unstable.
This picture is a close-up from of a slot from a customer’s Windblox BMW Z3 windstop, continually mounted on his car since November 2002. Since Windblox uses the best available material, it wears well over time, remaining crisp and clear. (Photo taken June 2009.)
