ZSTARR PVC Light Blockers For Side Tracks
ZSTARR light blockers are designed to reduce side light leakage by installing along the sides of inside window frames. The L-shaped PVC strips block light from the edges of blackout blinds and shades, helping to create a darker room without replacing existing shades. Best for: renters or anyone wanting a quick, adhesive-only solution that doesn’t require tools. Limitation: not a replacement for blackout shades; it enhances darkness by addressing gaps rather than blocking all light.
Bliwans Light Blocking Strips For Side Tracks
Bliwans offers 58″ long, 1.65″ wide, 1″ tall PVC side tracks designed to block light leaks from the sides of various shades, including cellular and roller shades. Best for: a budget-conscious setup that still aims for substantial darkness in bedrooms and media rooms. Caution: trimming requires careful measurement; use sharp scissors or a utility knife to preserve clean edges.
WINSMAR 100% Blackout Strips, Dual-Side Tracks
WINSMAR’s 58.5″ long strips are designed for easy at‑home cutting and flexible installation. Best for: those who want a wide compatibility with different shade types and a simple cut-to-fit approach. Use caution when cutting with a saw to ensure straight, clean edges. Not ideal if you need screw-based permanence in a high-traffic area.
DRSART 100% Light Blocking Strips With Dual Coverage
DRSART provides dual-side coverage from side leaks, aiming for total darkness along the edges. Best for: bedrooms and media rooms where complete side-light control is desired. Caution: installation notes indicate the need for careful measurement and alignment; improper placement can reduce effectiveness.
Miideayin U Channel Light Blocking Strips
Miideayin’s U-channel design provides a robust, two-sided barrier against light, with options for screw fixation or peel-and-stick installation. Best for: homeowners seeking strong, semi-permanent installation and extra durability on uneven walls. Limitation: some users may prefer screw-on installation for permanent setups; adhesive-only may loosen over time on textured surfaces.
Buying Guide: Key Purchase Considerations
- Coverage and fit: Measure window width and decide if you need one or two strips per side. Look for lengths around 58″ with options to trim.
- Installation method: Choose between peel-and-stick, screw-on, or a hybrid approach based on wall surface and permanence needs.
- Material and color: PVC is common and effective for light blocking; white is typical to match most blinds, but check for room-specific aesthetics.
- Compatibility: Ensure the strips work with your shade type (cellular, roller, blackout shades, etc.).
- Reliability: Thicker adhesive and non-slip designs help on uneven walls; some kits include magnets or adjustable fittings for easier positioning.
