Description
xZSTARR PVC Light Gap Blockers are adhesive L-shaped side tracks designed to reduce side light leakage for inside-mounted shades, sold as a 58" white 2-piece set.
Many blackout blinds and shades sit slightly narrower than the window opening to allow smooth movement, which creates thin side gaps that let light in. These ZSTARR PVC side blockers attach to the inside frame and help seal those edges so you get improved room darkening without changing your existing shades. They are made of rigid PVC, come in white to match typical trim, and arrive as two 58-inch strips that can be trimmed for a custom fit.
How do these side tracks reduce light coming in around shades?
The L-shaped design blocks the thin vertical space between the edge of the shade and the window jamb. By pressing close to the shade's edge, the strips interrupt the path light follows around the blind, producing a noticeably darker room when paired with blackout or room-darkening shades.
- Adhesive-backed PVC side strips create a tight edge seal.
- L-shaped profile overlaps the shade edge to minimize gaps.
- Works with roller, cellular, roman, and honeycomb shades.
Are ZSTARR light blockers easy to install and adjust?
Yes — installation is tool-free and uses peel-and-stick adhesive for quick placement. For best results, align the strip as close to the shade as possible and press firmly; if needed, standard household scissors or a utility knife can trim the PVC to match window height.
- No drilling or special tools required — peel, stick, and press.
- Trim-to-fit design: cut to exact window height with scissors.
- Two 58" pieces let you outfit both sides of a standard window.
Will these fit my windows and different shade types?
They are intended for inside-mounted shades with at least about 1 inch of flat jamb depth so the L-profile can adhere flush. The strips are compatible with many shade types but are not a substitute for a full blackout system; they improve edge sealing rather than replace a blind's blackout properties.
- Recommended for inside mounts with flat window frames and ≥1" depth.
- Compatible with cellular, roller, roman, and honeycomb shades.
- Returnable within 30 days if incompatible with your windows.
How durable and serviceable are these PVC light blockers?
The rigid PVC profile resists warping and maintains a straight edge over time, and the strong adhesive is made for interior use. ZSTARR offers after-sales support: contact them for replacements or refunds if parts are damaged or missing.
- Rigid PVC resists sagging and keeps a consistent seal.
- Adhesive designed for interior window jamb surfaces.
- Customer support and replacement options available through the seller.
Who is this for: Homeowners, renters, shift workers, or anyone seeking darker rooms for sleep, screen viewing, or privacy who already use inside-mounted shades will benefit most. These strips are best when you want an affordable, non-permanent upgrade to reduce side light without replacing existing blinds. If your window has an unusual frame profile, very shallow jamb depth, or requires professional mounting hardware, measure carefully or contact ZSTARR before purchasing to confirm compatibility.
