Have you ever encountered the problem of dealing with an abundance of light entering a hotel room, disrupting guest sleep and causing discomfort?
Blackout curtains are the definitive solution.
A blackout curtain, when correctly manufactured and installed, completely obscures external light. It is an essential component in bedrooms, screening rooms, and any high-end hospitality setting where total light control is critical to the guest experience.
This article delves into blackout curtains and fabrics to provide a comprehensive understanding of their benefits and technical applications in commercial projects.
5 Fail-Proof Steps To Choosing The Right Fabric
Choosing the right base fabric is the first step to achieving effective light control:
- Prioritise Naturally Opaque Fabrics: Opting for naturally dense and opaque fabrics aids the initial light-blocking capability.
- Density and Thickness: These physical properties significantly contribute to a fabric’s light-blocking performance.
- Tight-Woven Fabrics: Fabrics with a tight weave are far more effective at preventing light penetration.
- Lining Integration: Optimal light control and privacy are best achieved when a naturally opaque fabric is combined with a dedicated blackout lining.
- Focus on Performance: Always choose fabrics based on their proven light-blocking specifications rather than just aesthetic appeal.
3 Types of Fabric for Blackout Curtains
As a manufacturer, we classify light-blocking solutions based on performance:
- Dimout Fabric (Approx. 75% Blackout):
- Designed for partial light blocking to reduce incoming sunlight and glare.
- Ideal for spaces where you want to significantly reduce light but not necessarily achieve complete darkness (e.g., meeting rooms or hotel corridors).
- 100% Blackout Fabric (Integrated):
- Designed to block out all external light, achieving complete darkness without a separate lining layer.
- Commonly manufactured using integrated technologies such as laminated fabric or coated fabric.
- Ideal for high-priority areas like bedrooms and screening facilities.
- Additional Blackout Lining (To Enhance Blackout):
- A separate, thick layer of fabric attached to the back of the main curtain to enhance light-blocking abilities.
- Ensures a 100% blackout when paired with a dense, non-blackout face fabric.
- Note on cost: This method requires additional sewing and material cost due to the double layer of fabric.
Ever Wondered How 100% Blackout Curtains Are Made?

The main fabric is typically made from tightly woven, dense synthetic fibres like polyester or nylon. The key to 100% blackout lies in the manufacturing method.
There are three primary methods we use to ensure a complete blackout finish:
- Blackout-coated: The reverse side of the fabric is treated with a three-layer coated acrylic suede (often called ‘three-pass’ coating). This method is highly effective at both blocking light and providing thermal insulation.
- Blackout Lamination: Metallised films or other opaque layers are laminated to the base fabric to achieve a complete light barrier.
- Sewn-in Blackout Lining: The simplest method, involving stitching a separate, opaque or thick fabric (often pre-coated) onto the back of the curtain’s main fabric.
To prevent light leakage around the edges, manufacturing techniques often include sealed edges, overlapping layers, and a weighted bottom hem to ensure a tight, precise fit when hung.
Top Merits of Blackout Curtains for Hospitality Projects
Blackout curtains offer guests and proprietors four key advantages:
- Controls Light: Provides complete darkness by obstructing natural and artificial light sources, directly contributing to superior, restful guest sleep.
- Saves Energy: Blackout curtains help insulate windows, significantly reducing heat gain in the summer and heat loss in the winter, which lowers cooling and heating costs.
- Maintains Privacy: Due to their density, they provide absolute visual privacy, preventing people on the outside from seeing inside the space.
- Reduces Noise: The thick, dense nature of blackout fabrics helps dampen outside noise, resulting in a quieter, more tranquil guest environment.
Decoding the Magic of Blackout Fabrics
Choosing the right blackout fabric is critical for achieving the desired light control, privacy, and comfort level of your space. By considering factors such as density, thickness, and the specific coating or lining method, you can select the suitable material. Adding a dedicated blackout lining can enhance light control even more.
