Motorized screens live or die by one property: rollability. This page explains why material choice decides it, and how we test it.

The daily cycle problem

A motorized screen rolls up and down every day. Each cycle bends the screen surface around a roller. Over the life of the product, that adds up to thousands of bends — and the roll-cycle life of the screen material decides the life of the whole screen.

Why only silicone rolls repeatedly

Fresnel optics are built from fine concentric microstructures. In most materials, those microstructures fatigue under repeated rolling: they crack, and the screen loses gain. That limited roll life is why other Fresnel materials ship as rigid panels or as bare films.

Silicone behaves differently. Its flexible molecular structure absorbs repeated bending without fatiguing the optical surface. Only a silicone Fresnel screen can be rolled again and again and keep performing — which is what makes a finished, motorized Fresnel screen possible at all.

How we test: PROSILEX-QTP-ROLL-001

We test roll-cycle durability under our own protocol, PROSILEX-QTP-ROLL-001. Samples are rolled repeatedly around mandrels and inspected at checkpoints through the test, with optical performance tracked as the cycles accumulate.

Testing is in progress. Results are published as checkpoints complete — no claims are made ahead of measured data. If you would like the test summary when it is published, send us an inquiry and we will share it with you.
