Why Home Glass Needs Switchable Privacy
Bathrooms: blinds mildew in humidity, frosted glass eliminates the clear view permanently, curtains reduce daylight and gather dust. Bedrooms: curtains block morning light or sacrifice privacy — you choose one or the other, never both. Home offices: glass partitions need privacy for video calls without permanent frosting that kills the open-plan feel.
The mechanism is always the same: physical window treatments are binary — open or closed — they cannot serve both states simultaneously. Smart film resolves this at the molecular level through PDLC liquid crystal orientation. When 48/65V AC is applied, molecules align and the film becomes transparent. When power is removed, molecules scatter randomly and the film becomes frosted. The transition completes in ≤ 20 ms (PRO) or ≤ 60 ms (standard) — effectively instantaneous. No moving parts, no dust path, no mechanical wear.

Installation for Residential Glass
| Step | Detail |
|---|---|
| Film application | Dry install self-adhesive film directly onto existing glass after cleaning with isopropyl alcohol and lint-free cloth. |
| Edge clearance | Size film 2–3 mm shorter than visible glass edge on all sides to avoid edge stress. |
| Busbar position | Busbar on top edge. Must not touch metal trim or frame. |
| Edge seal | Neutral-cure silicone mandatory — DOWSIL 895/795 or Tosseal 381. Especially critical in bathrooms where humidity attacks unsealed edges. |
| Transformer mount | Install in adjacent wall cavity or closet. Wire 48/65V AC output to film busbar. Qualified electrician required for mains connection. |
Control Methods for Home
Wall switch
Simplest — toggle privacy with a physical switch. Ideal for bathrooms.
RF remote
Guest-friendly — no app needed. Handheld remote controls one or multiple zones.
Wi-Fi app
HomeKit, Alexa, Google Home integration. Scheduled automations and voice control.
Door sensor
Automatic — close door → privacy, open door → clear. No manual interaction needed.

Procurement Guide — Residential
Understanding residential cost drivers before requesting a quote shortens the proposal cycle and ensures accurate landed cost for your home project.
- 01
Model tier
EL-L2-PRO is recommended for bathroom enclosures where the 165° viewing angle and 2.36% ON-haze deliver the best residential aesthetics. EL-L2 is best value for bedrooms. EL-X1 suits home offices where high clarity matters for video calls.
- 02
Format — self-adhesive sheet recommended
Self-adhesive sheet is the recommended format for homes — it arrives ready to install with no professional processing required. Roll film requires buyer-side cutting and electrode processing, which adds in-house labor not typical for residential projects.
- 03
Width surcharge
Standard residential glass widths (600–1,200 mm) fall within standard capacity. If any pane exceeds 1,500 mm width, a capacity surcharge applies due to narrower production lanes for wider film.
- 04
Control add-ons
Budget 15–25% of film cost for the transformer and your preferred control method. A basic wall switch adds minimal cost; a Wi-Fi smart-home bridge (HomeKit/Alexa/Google Home) adds more but enables scheduled automations and voice control.
- 05
Volume — multiple rooms
Multiple rooms in a single order qualify for tiered pricing — unit cost decreases as total area increases. Combine bathroom, bedroom, and home office partitions in one order for the best per-square-meter rate.
- 06
Shipping and lead time
FOB and EXW terms supported. Standard self-adhesive sheet orders ship in 5–10 business days. OEM/ODM available for custom sizes. Neutral-cure silicone sealant (DOWSIL 895/795, Tosseal 381) should be ordered simultaneously for edge sealing.
Frequently Asked Questions
Residential-specific questions about smart film for homes. See the full FAQ for cross-product questions.
Yes, with proper sealant. Neutral-cure non-solvent silicone (DOWSIL 895/795) prevents moisture ingress at the busbar. Operating temperature -20°C to 70°C covers bathroom humidity cycles. Power at 48/65V AC via a dedicated transformer ensures no mains voltage exposure at the glass surface. The film itself contains no hazardous materials and is safe for residential environments including homes with children.
Yes. The Wi-Fi bridge integrates with HomeKit, Google Home, and Alexa. App-based switching, scheduled automations (e.g., bathroom privacy at night), and voice control are all supported. Multiple zones can be grouped — one tap switches all home partitions simultaneously. The bridge communicates with the 48/65V AC transformer channel controller, so no additional relays are needed in most residential installations.
PDLC switches in ≤ 60 ms standard (EL-L2) or ≤ 20 ms PRO models (EL-L2-PRO). Both are instantaneous to human perception — there is no noticeable delay between pressing the switch and the glass changing state. The transition is an electro-optical molecular alignment change, not a mechanical motion, so it is repeatable and consistent over the > 100,000 hour rated lifespan.
Skilled DIY is possible for the self-adhesive film application on straightforward glass surfaces. However, the 48/65V AC transformer must be wired by a qualified electrician to ensure code compliance and proper grounding. Transformer sizing is based on total film area — our engineering team provides specifications with every order. For bathroom installations, professional sealing with neutral-cure silicone (DOWSIL 895/795) is strongly recommended to protect against humidity ingress.
