Frequently Asked Questions
What is a tensioned projection screen and why is it better?
A tensioned projection screen uses mechanical tension to keep the screen surface perfectly flat and wrinkle-free. Unlike non-tensioned screens that can sag over time, tensioned screens maintain consistent image quality, eliminate hot-spotting, and provide superior picture uniformity across the entire projection area—essential for professional presentations and high-stakes environments.
Can the Da-Lite Tensioned Advantage Electrol be installed in existing buildings?
Yes. The Tensioned Advantage Electrol is specifically designed for retrofit installations where the recessed case is installed during construction and the electric screen mechanism is added later. This flexibility makes it ideal for renovations and upgrades to existing commercial spaces without major structural modifications.
Is the plenum-rated case important for my installation?
Absolutely. The plenum-rated case meets fire safety codes required in commercial HVAC plenums (air handling spaces above drop ceilings). If your installation includes a plenum space, plenum-rating is mandatory for code compliance and safety—the Da-Lite Tensioned Advantage Electrol meets these critical requirements.
What screen surfaces are compatible with the 21806LS model?
The Tensioned Advantage Electrol supports multiple screen surface options to match your projection needs and ambient lighting conditions. Available surfaces include high-contrast, standard white, and specialty finishes. Consult with your AV integrator to select the optimal surface for your specific application and projector type.
