Light curtains are semi-translucent window treatments that weigh between 40 and 150 grams per square meter (GSM) and filter direct sunlight while maintaining interior privacy. Sarelli Interiors Textiles produces light curtains using fine linen, silk, and cotton blends to achieve a delicate drape and high light transmission rates.
Physical Characteristics And Weight Specifications Of Light Curtains
The defining characteristic of a light curtain is the fabric weight. Standard drapery fabrics weigh between 250 and 400 GSM, whereas light curtains fall strictly below the 150 GSM threshold to ensure proper light filtration and a delicate drape. Sarelli light curtains woven from 100 percent European flax linen typically weigh 85 GSM and feature a thread count of 60 threads per square centimeter. An 85 GSM linen construction allows exactly 45 percent of visible light to pass through the light curtain during peak daylight hours. The low weight of light curtains requires specialized handling during manufacturing. Sarelli artisans finish the hems of light curtains using a blind stitch technique that adds only 12 grams of additional weight per linear meter. The blind stitch finishing ensures the light curtain maintains a vertical drape without puckering at the base.
Material Composition And Light Transmission Rates For Light Curtains
The materials used in light curtains determine the exact light transmission percentage and the structural durability of the window treatment. Sarelli Interiors Textiles relies on three primary fibers for light curtains: silk, linen, and long-staple cotton. Silk light curtains feature organza or chiffon weaves measuring between 8 and 12 momme. An 8-momme silk light curtain transmits up to 65 percent of visible light. Linen light curtains offer higher durability and transmit between 35 and 50 percent of visible light depending on the weave density. Clients can review the exact fiber percentages on the Fabrics Composition page. Blending 70 percent linen with 30 percent cotton creates a light curtain that resists UV degradation for up to 15 years under direct southern exposure.
| Material Composition | Fabric Weight | Light Transmission | Estimated Lifespan (Direct Sun) |
|---|---|---|---|
| 100% European Flax Linen | 85 GSM | 45% | 12 Years |
| 100% Silk Organza | 8 Momme | 65% | 8 Years |
| 70% Linen / 30% Cotton | 110 GSM | 35% | 15 Years |
Production Methods For Sarelli Light Curtains
Manufacturing lightweight textiles requires specialized loom settings to prevent thread breakage. Sarelli uses rapier looms operating at a reduced speed of 250 picks per minute to weave light curtain fabrics without damaging the fine warp threads. The Sheer Fabrics Production process involves washing the raw fabric in water heated to exactly 40 degrees Celsius to remove natural sizing without shrinking the delicate fibers. A standard 3-meter by 3-meter light curtain requires approximately 4.5 hours of active loom time. After weaving, inspectors examine the light curtains over illuminated glass tables to identify any weaving flaws larger than 0.5 millimeters. Clients can explore the full catalog of light curtain textiles in the Fabrics Collection.
Cost And Lead Times For Custom Light Curtains
Custom light curtains require precise measurements and tailored production schedules. Sarelli light curtains cost between 120 EUR and 280 EUR per linear meter depending on the specific fiber composition and the required loom time. Silk organza light curtains represent the higher end of the pricing tier because the raw silk material costs significantly more than flax. The standard lead time for a custom light curtain order is 4 to 6 weeks from the date of final measurement approval. Shipping delicate light curtains requires rolling the fabric on rigid cardboard tubes measuring 10 centimeters in diameter to prevent permanent creasing during transit.
