Buying Guide
- Privacy needs: If daytime privacy is the priority, choose one-way mirror styles (daytime privacy). For continuous privacy, consider films with stronger reflected effects and nighttime curtains.
- UV protection: Prioritize films that advertise high UV rejection (e.g., 80–99% range) to protect skin and furnishings.
- Heat control: For cooling or heating savings, select films with high infrared rejection and reflective properties that bounce heat away from interiors.
- Application method: Glue vs. glue-free (static cling) affects installation and removal, especially in rentals. Static cling products are easier to remove with no residue.
- Window type and safety: For multi-pane or tempered glass, confirm compatibility and consider explosion-proof or safety-enhanced options if impact is a concern.
- Light transmission: Visible Light Transmittance (VLT) influences how bright rooms stay. Higher VLT means more natural light but potentially less privacy.
