Choosing Blackout Blinds: Blackout, Dimout and Light Gaps

What Is the Difference Between Blackout and Dimout?

Blackout describes fabrics designed to block light passing through them. Dimout refers to fabrics that reduce light without promising the same darkening performance as blackout. After reading the product name, check the light-transmission information in its description; do not infer a particular percentage from the term alone.

If a product page states a light-blocking percentage, ask whether it applies to the fabric or the complete blind system. A fabric specification should not be read as a guarantee of darkness throughout the room.

Why Can Light Enter Around Blackout Fabric?

Gaps between the fabric and the wall or frame can allow light through. Consider the fitting distance at the top, side gaps and the bottom edge together. A wider overlap or a suitable system that controls edge gaps may help in some installations; confirm compatibility with both your window and the product.

Before replacing an existing blind, observe where the light enters. If the middle of the fabric is bright, start with fabric choice; if only its edges are bright, start with positioning and gaps. Both situations can occur together.

Bedroom: Note When the Light Arrives

Is the problem morning sunshine or street lighting at night? Look at the window at the time that bothers you before replacing the blind. Sharing a photo and the direction of the light is more informative than simply asking for a thick blind. Explain your darkening expectations too: is less light enough, or do you want the room as dark as possible?

Study: Consider the Screen and Window Together

Note the times when you experience screen glare. You may want to close the blind then, but if natural light matters during the rest of the day, include that in your selection criteria. Do not judge a model only in its fully closed position.

Living Room: Think About Different Uses Throughout the Day

You may want a bright living room during the day and a dimmer space for films in the evening. Deciding which use takes priority helps narrow your choices before shopping. Rather than assuming one product meets every need equally, check how it opens, closes and adjusts the light.

Separate Colour Choice from Fabric Performance

A dark-looking fabric is not necessarily blackout. A light-coloured product may also have blackout properties. Read the description for the particular colour and fabric code you choose instead of deciding by the colour name.

If samples are available, view them alongside your room’s walls and furniture. A sample helps with colour and texture; it does not show the light gaps around an installed blind. Treat fabric choice and fitting assessment as separate steps.

Five Questions to Ask Before Ordering

Keep the answers with the details of your chosen product. Two models that look identical in photos may differ in fabric or fitting details.

• Is my chosen fabric blackout or dimout, and what property does the description specify?
• Does the stated blackout property apply to the fabric or the installed system?
• Where will gaps remain around the window with this fitting method?
• Will I be able to operate the window and handle comfortably once the blind is fitted?
• What are the care and cleaning instructions for my chosen fabric?

Will a Blackout Blind Make the Room Completely Dark?

Blackout fabric alone does not guarantee this. Edge gaps, fitting and other light sources in the room affect the result.

Can Dimout Blinds Be Used in a Bedroom?

It depends on how dark you want the room. Dimout may be worth considering if you want to reduce light; if you expect strong darkening, check whether the product can meet that need.

Does a Blackout Blind Also Provide Thermal Insulation?

A blackout property does not establish a particular thermal-insulation or energy-saving result. If that matters to you, request technical information for the selected product separately.

Narrow Down Your Options in the Kidmex Collections

Start comparing models in the roller blind collection or the light-blocking pleated blind range. For a glazed balcony, also consult the balcony blind selection checklist. Make your final decision using current fabric information, fitting compatibility and the room’s light requirements together.
