1. Core Value of Tab-Tension Screens
In a middle school lecture hall, the teacher presses the remote, and the electric tab-tension screen descends smoothly. The 150-inch surface remains perfectly flat—this is its key advantage: dual tension from side wires and bottom weight bar eliminates curling and V-shaped wrinkles that plague regular electric screens over time.
This design balances flexibility and flatness: ideal for commercial/educational settings with frequent use, and home theaters demanding immersion. For screens over 130 inches, tab-tension structure is critical to prevent deformation.
2. Material Selection Comparison Table
| Material Type | Structure | Flatness | Application | Customization Notes |
|---|---|---|---|---|
| PVC Soft Screen | Flexible base | ★★★★★ | Home theaters, premium meeting rooms | Must pair with tension wires; curved customization available |
| Fiberglass Screen | Glass fiber weave + PVC coating | ★★★★☆ | Small classrooms, offices | Tension-free for ≤120 inches; moisture-proof required |
| Vinyl Screen | Plastic fiber + PVC film | ★★★☆☆ | Temporary displays, budget projects | Not recommended for large sizes; temperature-sensitive |
Critical Note: Low-cost “fake tab-tension screens” use fiberglass/vinyl—their rigid base makes tension wires useless. Only PVC soft screens truly need tab-tension for flatness.
3. Installation & Maintenance (2025 Standards)
Pre-Installation Preparation
- Frame Allowance: Custom frames need 15-25mm extra width (updated from 10-20mm)
- Ceiling Space: Reserve ≥12cm for ceiling-mounted models (refer to curtain box standards)
- Wall Reinforcement: Use 12-16cm extended expansion screws for insulated walls; fixture spacing ≤50cm
Transportation & Inspection
- Packaging Check: Ensure fully enclosed cartons with pearl cotton and corner protectors
- Handling Rule: Always carry vertically; horizontal dragging causes deformation
- On-Site Inspection: Check for scratches immediately—PVC scratches cause image black spots
Daily Maintenance
- PVC Screens: Wipe with damp lint-free cloth; avoid alcohol
- Fiberglass/Vinyl: Washable but air-dry naturally; avoid direct sunlight
- General Rule: Keep sharp objects away; check wire tension monthly
4. FAQs for Customization
Q1: When is a tab-tension screen necessary?
A: Recommended for screens over 130 inches, especially 16:9 wide formats. Regular electric screens sag under their own weight. We customize based on your projection distance for optimal clarity.
Q2: What parameters are needed for customization?
A: ① Installation type (ceiling/wall/mobile); ② Projector brightness (affects gain selection); ③ Viewing distance (screen width = 0.6 × viewing distance); ④ Special needs (curved/anti-light/3D).
Q3: How long do tab-tension screens last?
A: High-quality PVC models last 8-10 years. Extend lifespan by: operating monthly to prevent wire aging, ventilating in humid areas, and fully retracting when stored.
