Complete Darkness Shades – Absolute Zero Light Leak

Standard blackout shades block light through the fabric, but light can still sneak around the edges. Complete Darkness Shades are engineered to eliminate every possible path of light—through the fabric, around the sides, under the bottom, and over the top. This is the ultimate solution for shift workers, parents of light‑sensitive infants, home theater enthusiasts, and anyone who demands absolute, verifiable darkness. The system combines our certified 100% blackout fabrics with precision‑engineered light‑sealing accessories: aluminum side channels with brush seals, magnetic bottom bars that adhere to the sill, and optional top seals that close the gap above the headrail. When fully deployed, the shade creates a light‑tight enclosure that meets the requirements of sleep disorder clinics, MRI suites, and commercial cinemas. Available on select roller, cellular, and roman blackout shades. Motorized operation required. Because darkness shouldn't have loopholes.

Perimeter Light Sealing System

Complete Darkness Shades use a three‑part perimeter sealing system that eliminates every common source of light leakage:

  1. Side Channels — 1.2mm aluminum channels mount to the window jambs and use nylon brush pile to contact the fabric edges, blocking side light. Each set is custom‑cut to the exact drop of your shade.

  2. Magnetic Bottom Seal — A continuous magnetic strip inside the bottom bar connects to a ferrous sill strip, creating a tight compression seal.

  3. Top Seal (optional) — A flexible PVC extrusion mounts to the top of the window frame and compresses against the headrail.

Together, these components eliminate edge, bottom, and top light leaks.

Certified 100% Blackout Fabric

Every Complete Darkness Shade begins with our certified 100% blackout fabric.

  • Roller & zebra shades use our TripleCell™ laminate (decorative face, black core, white backing).

  • Cellular shades use our TripleCell honeycomb construction.

  • Roman shades use a sewn‑in blackout liner behind the decorative fabric.

Independent testing confirms 0.00% light transmission through the fabric itself.

Styles Available

  • Complete Darkness Roller Shades — Sleek, minimalist, ideal for home theaters and bedrooms

  • Complete Darkness Cellular Shades — Insulating honeycomb cells, energy‑efficient, quiet

  • Complete Darkness Roman Shades — Soft fabric folds with a hidden blackout liner

Zebra and sheer shades are not available due to inherent light gaps in their mechanisms.

Motorization Required

Because of the added weight of the side channels, magnetic bottom bar, and the precision needed for a true blackout seal, Complete Darkness Shades are motorized only. High‑torque motors are calibrated for the resistance of brush seals and magnetic breakaway force. Battery (3–5 year life) and hardwired options are available.

Commercial & Medical Grades

Complete Darkness Shades meet the strict light‑tight requirements of:

  • Sleep disorder clinics and research labs

  • MRI suites and medical imaging facilities

  • Pharmaceutical research and cleanrooms

  • Commercial cinemas and screening rooms

Certification documentation is available for ASTM E283 (air leakage) and modified light transmission testing.

Custom Sizing with Light‑Tight Guarantee

We guarantee zero detectable light transmission when the shade is properly installed. If any light is visible around the perimeter, we will work with you to resolve the issue — including replacing components at no cost.
