See Tips to Lighten, Ventilate and Decorate Windowless Room

Is there a solution for a windowless room? Yes, and today’s post will tell you how to solve the problem of lighting and ventilation, two of the main negative aspects that affect a windowless room.

Come and see!

What is the problem, after all, of a windowless room?

Maybe deep down you are still asking yourself: what is the problem with a windowless room?

The answer is simple: healthiness. And do you know what this means? In architecture, the term salubrity is used to indicate environments with little or no healthy conditions for hygiene and human well-being.

In other words, a room without a window interferes with the health and quality of life of its residents.

Without ventilation and illumination, the room can become a propitious place for the appearance of mould and mildew, besides being a perfect source for dust mites.

Not to mention that closed environments still generate discomfort and a feeling of tightness, which can lead to cases of claustrophobia.

The good news is that even without windows it is possible to get around the problem of lack of light and ventilation with some measures, some very simple, others a little more complex, but still worth your attention. Keep following.

Check out how to increase the natural (or artificial) ventilation of a windowless room below:


One of the first things you might think of doing to ventilate a windowless room is to integrate the room with some other room in the house.

Yes, you’ll need to break down walls for this, but the end result is worth it. The room will gain ventilation and lighting.

But what about privacy? We will talk about it next:


One of the possible solutions to integrate a windowless room without losing privacy is to bet on a wall of cobogós.

The cobogós guarantee a good passage of light and ventilation without leaving the room totally open.

In other words, you can remove one of the walls creating the integration mentioned above without any damage.

Fans and air conditioners

A ceiling or wall fan helps a lot in the ventilation of the room. And although this is a form of artificial ventilation, it is one of the most effective, simple and cheapest that exist.

If you choose a wall fan, it should ideally be installed at the back of the room so that the air can circulate evenly throughout the room.

Turn on the fan every day (yes, even in winter) for at least half an hour. This time is more than enough to renew and ventilate the whole room.

Another option is to install an air conditioner in the windowless room. Although it is a more expensive alternative and requires specialized labour to install, the air conditioner has the advantage of also working as an environment climatizer.

Remember to choose a model of air conditioner with a power adequate to the size of your room, okay? This way you save energy and ensure you get the maximum benefits that the device has to offer.

After ventilating, you also need to ensure the lighting. Let’s check out the ideas?

Artificial lighting design

Start with a good artificial lighting project. The best choice of lamps for this type of environment are LED lamps. Vary between white and yellow bulbs to ensure comfort and, at the same time, a good luminosity to perform tasks.

The ideal is that you can install support lights on the ceiling. A good solution is to use rails of directional spots. Besides ensuring a modern look to the room, this type of lighting does not require breaking to pass wires, since the ducts and conduits are apparent.

Ensure central and side lights for a complete illumination. Depending on the size of your room, it is also worth investing in wall lights, through sconces, for example.

Another great option to complement the lighting is to use LED strips under shelves, niches and cabinets. The room becomes cozier and with the right amount of light for your needs.

Table and floor lamps can finish the project bringing, in addition to light, a touch more to the decoration.

Glass walls

If you have bet on the idea of integration between the bedroom and another environment of the house, then you can take advantage of this solution here.

The glass wall guarantees all the lighting the room needs, without having to sacrifice your privacy. That’s because curtains can be installed next to the wall.

This way, when you need a darker environment or to change clothes, you won’t have to worry about visitors in the living room, for example.

It is only important to mention that the wall should be made with laminated or tempered glass, the same used in doors, since they are more resistant to impacts. The installation must also be done by professionals.

Glass blocks

Besides the glass wall, you can also use glass blocks. This type of block allows light to pass through and even allows ventilation, if you choose the hollow models.

Glass blocks also have the advantage of being wavy, ensuring privacy in the room, as the images are distorted.


The skylight is a great solution for lighting a windowless room. However, it is one of the most expensive and complex.

In short, the skylight is a type of window, but instead of being on the wall, it is on the ceiling.

Another feature of the skylight is that it also serves as ventilation for the room without window, provided you choose models with opening.

It has one more advantage: the skylight can take on any size you want, since it is made to measure.

However, as we have already said, this alternative is complex and requires specialised labour. Any error in the installation can be disastrous and leave you with a room dripping water on rainy days. Therefore, evaluate well the company or professional that you intend to hire to perform the service.

In addition to the physical and structural changes to the bedroom, you still have the option of modifying a few things in the decor to ensure that the windowless room looks as pleasant as possible.

Light colours

The light colours bring a feeling of amplitude and still help to propagate light. Therefore, they are very welcome in windowless rooms.

Change the colour of the walls, the carpet and the bedding. Prefer colours like white, beige and light grey.

To contrast and bring comfort to the room, you can use warm and earthy tones. A good choice are the shades of orange and burnt red, and mustard yellow. Use these shades sparingly and in details of the bedding and decorative objects.

Few furniture

To avoid the feeling of tightness (common in rooms without windows), the ideal is to use few furniture in the decoration. Keep only the main and indispensable ones.

The bed, the wardrobe and a desk-type table may be enough for a small windowless room.

In a larger room, you can still have other furniture options that increase the functionality and comfort of the room, such as a bedside table or an armchair to help change clothes.

The less furniture in the room, the greater the feeling of illumination, since there will be no shadow points in the environment.

Another tip is to try to place the furniture on a single wall, so the amplitude will also be greater.


The plants are great to renew and purify the air, besides being extremely decorative. That is, they are perfect for rooms without windows, if it weren’t for one detail: every plant needs light.

But if you have already managed, somehow, to amplify the presence of natural light in the room, then it is worth bringing some shade species into the environment.

Some plants, such as St George’s Sword, Zamioculca and boa trees adapt well to environments with little light.

Be careful with some materials

Be careful with some materials that may be in your room. This is because there are materials which absorb a lot of humidity and can quickly deteriorate and become mouldy.

This list includes furniture and objects made of leather, suede and wood. The ideal in these cases is to offer some kind of anti-humidity treatment to avoid damage caused by humidity.

Use mirrors

Mirrors are also very welcome in a windowless room. With them, you visually enlarge the spaces and even get extra lighting, since the mirror reflects the light.

So, if you want a simple solution to improve the lighting in a windowless room, it is worth placing a mirror facing the door, so that it can reflect the light coming through it.

Consider changing rooms

Finally, if you’ve evaluated all these possibilities, and still none of them seem feasible at the moment, one of your last (and drastic) options is to switch rooms.

Yes! You can reinvent your home and change the environments so that you can have a fresh and bright room.
