The PolarMax Aerie Tension from EPV Screens is a motorised "in-ceiling" projector screen using a specialty material able to reject the washout effects of ceiling lights, as well as off-axis ambient lighting.
EPV says the 1.3 Gain PolarStar ceiling and ambient light rejecting (CLR/ALR) material is durable enough for heavy use without degrading. It achieves off-axis light rejection by using a multi-layer matrix with reflective and absorbent micro-particles with high contrast diffusion layers to eliminate up to 85% of ambient light. It is ISF-certified and GREENGUARD/UL 2818 certified for safe indoor air quality emissions. A tab-tensioning system provides a flat, taut surface for optimal picture performance.
