| 100% Blackout Membrane-Laminated Drapery (3-Ply Textile) | Decorative linen/velvet/jacquard face + internal black PU membrane + soft backing scrim | 340 – 520 g/m² (0.70 – 1.10 mm) | 100% Light Blockage (Tv = 0.00%) | Superior thermal insulation (gtot ≤ 0.28) and condensation resistance | Supple S-Wave drape compared to foam coatings plus high sound absorption (αw ≈ 0.65) | 5-Star hotel suites, luxury master bedrooms, and VIP projects without separate lining |
| 85%–98% Room Darkening (Triple-Weave Dimout Drapery) | Chemical-free 3-ply weave integrating high-density black weft/warp yarn sandwiched between two decorative faces | 220 – 350 g/m² (0.40 – 0.55 mm) | 92%–98% light reduction in dark tones; 80%–88% in ivory/beige tones (Tv = 2% – 15%) | Reduces solar heat gain by 30%–40%; 95%+ UV blockage | Fluid S-Wave drape, breathable, machine washable at 30°C, zero coating peel or cracking | Residential bedrooms, studies, hospital rooms • Pair with blackout lining if 100% pitch darkness is required |
| Solar Screen Roller Shade (1% – 3% Openness Factor) | 30% Polyester + 70% PVC-coated yarn or 36% Fiberglass + 64% PVC basketweave | 410 – 540 g/m² (0.55 – 0.75 mm) | Visible transmittance Tv = 1% – 3%; eliminates 97% of monitor glare | EN 14501 Indoor gtot = 0.32 – 0.42; Exterior Zip Screen gtot = 0.08 – 0.14; 97%–99% UV block | Zero sag/stretch dimensional stability; preserves daytime view out while blocking view in | South/West commercial glass facades, executive offices • Combine with drapery for nighttime privacy when indoor lights are on |
| Solar Screen Roller Shade (5% – 10% Openness Factor) | 30% PES + 70% PVC or Trevira CS (100% Halogen-Free IFR Screen) | 360 – 450 g/m² (0.45 – 0.60 mm) | Visible transmittance Tv = 5% – 10%; abundant natural daylight and clear outward panorama | EN 14501 gtot = 0.43 – 0.52; 90%–95% UV blockage | Ultrasonic sealed edges prevent fraying; antistatic dust-repellent finish | North/East offices, restaurants, hotel lobbies, and panoramic living rooms |
| Duette Honeycomb Cellular Pleated Shade (Translucent & Blackout) | Hexagonal double-wall air-pocket spunbond/woven polyester; blackout version features internal aluminum foil | 160 – 240 g/m² (20 mm / 25 mm cell size) | 65% light filtering in translucent; 99%–100% blackout in foil-lined Duette (zero visible cord holes) | Cellular air pockets reduce glazed balcony and skylight heat loss by up to 46% | Concealed internal lift cords; Top-Down / Bottom-Up dual operation | Folding glass balconies, winter gardens, skylights, and tilt-and-turn windows |
☀️ Total Solar Energy Transmittance (g_tot) Formula (EN 14501)
Total Solar Factor: g_tot = τ_e + α_e × G_i. Interior pearl/metallized-backed solar screens achieve g_tot ≤ 0.25–0.32, cutting HVAC cooling loads by 28%–38%, while exterior Zip Screens achieve g_tot ≤ 0.08–0.14.

❓ Frequently Asked Engineering & Tender Questions
❓ What is the difference between 3-Pass Blackout and Triple-Weave Dimout curtain fabrics?
3-Pass Blackout uses three layers of acrylic/PU foam coating to block 100% of light (0 Lux under AATCC TM203). Triple-Weave Dimout is uncoated, weaving a dense black core yarn between two faces to block 92%–98% light in dark colors and 80%–88% in light colors with a soft washable drape.
❓ How do I choose between 1%, 3%, and 5% Openness Factor (OF) Solar Screen blinds?
Specify 1% or 3% OF on south/west office facades for strict VDU glare control (EN 14501), and 5% OF on north/east facades for maximum outward view-through.
