The Functions of Flannelette Blackout Fabric

Blackout fabric and drapery linings are used to create a dark and private environment, particularly in bedrooms. They also block out light and heat from the sun, reducing air conditioning costs.

They also have insulating and noise-dampening properties, depending on the fabric. This is especially beneficial if you live in an urban area or work at night.
Light Control

Blackout fabrics are most often used in curtain fabrics for a variety of reasons, including blocking light from entering a room while still maintaining the functionality of a fabric. This is particularly useful for people who spend a lot of time in rooms with little to no natural light.

Typical blackout fabrics are coated with a light-blocking layer or have a special finish applied to them. A few of these fabrics also contain other beneficial functions, such as a noise-reducing coating or thermal insulation.

For the best results, consider choosing heavyweight polyester fabric or poly/cotton blends. These fabrics are generally more tightly woven than their lighter counterparts and will have the best chance of blocking out as much light as possible.
Thermal Insulation

Thermal insulation reduces the flow of heat between objects of different temperatures. Objects are naturally prone to heat transfer through contact, convection and radiation.

The effectiveness of a material at blocking the flow of heat is largely determined by its thickness and R-value. Materials with a higher R-value generally have more resistance to the flow of heat and are therefore more effective at insulating.

Many different types of thermal insulators are available, and the best choice for a specific application will depend on the specific needs of the building. Some of the most popular options include cellulose, fiberglass batting, and spray foam. Others are made from renewable resources, such as wool and cork.
Sound Insulation

A blackout lining fabric that blocks all light is also an excellent sound absorber. It can be used in draperies, upholstery, and film production work.

The fabric is commonly used in theaters and in video environments. It is soft and has a matte finish.

In addition, it is fire retardant and 98% opaque.

Acoustic fabrics reduce reverberation levels within venues, and improve speech intelligibility by shortening reverberation times. Many acoustic fabrics are fade and mildew resistant, and available in a wide variety of colors, patterns, and textures.

Fiberglass sound blankets and ceiling banners help reduce reverberation at the ceiling. These are similar to acoustic baffles but are covered in Guilford sound transparent cloth. These are ideal for reducing echo and reverberation in offices, schools, churches, and other large spaces. They are typically 4' x 20' and 2" or 4" thick. They can be mounted on frames or tracks to create air gaps between the blankets and walls to enhance sound control.
Comfort

Using the right fabrics in the right quantities can make or break a home decor project. This is especially true of the ills in the bedroom. The trick is to find the etiquette amongst the plethora of options. This is the most important part of the decision making process. The best place to start is with the room you intend to furnish. The ensuing planning will help you achieve the aforementioned goals without the dreaded adolescence. The resulting design is functional, stylish and most importantly, free of blemishes. This is also the best place to shop for the latest in window fashions.
