A more ventilated house provides thermal comfort, air quality, and a light atmosphere in daily life. In a country with a predominantly hot climate, like Brazil, thinking about solutions to improve natural ventilation and air circulation in interiors makes all the difference. The good news is that major renovations are not required to achieve this effect.

The decor has a strategic role in this task. From the choice of colors and materials to the positioning of furniture and objects, it is possible to adopt small changes with an immediate impact on the sensation of freshness and flow of the spaces. Below, check out 10 decoration tricks that help to achieve a more ventilated house.

1. Bet on light colors on the walls


Light colors, such as white, beige, off-white, and pastel tones, reflect natural light better and expand the sensation of space. This makes the project more illuminated and ventilated, especially in areas with little sunlight.

2. Choose furniture with a light design


Straight-lined furniture, with visible legs and open structures, contributes to visual flow. By keeping the floor clearer and the volumes lighter, they help create the perception of a more ventilated house.

3. Invest in natural fabrics


Natural fabrics (such as cotton, linen, and voile) are ideal for curtains, cushion covers, and bedspreads. In addition to being breathable, they promote air circulation and provide a light texture for the decor.

4. Keep windows and doors unobstructed


Avoid positioning large furniture or objects in front of doors and windows. Keeping the openings clear facilitates the entrance of light and airflow between the rooms, creating cross ventilation and making the house cooler.

5. Use mirrors to amplify light


Mirrors positioned correctly help reflect natural light, increasing brightness in the projects. Place them on walls opposite windows or in strategic locations to multiply the luminosity.

6. Reduce excess objects


Projects with many furniture items and decorative items tend to retain heat and hinder air circulation. Invest in a more streamlined and functional decoration, with free spaces between items.

7. Opt for cool floors


Materials such as porcelain, ceramics, and burnt cement are good choices for those seeking a more ventilated house. These floors have a lower capacity to retain heat and provide a sensation of freshness when walking barefoot.

8. Include plants in the decor


In addition to beautifying the space, natural plants help regulate humidity and temperature in the projects. Species such as pothos, peace lily, and raffia palm are great options for interiors, bringing life and lightness.

9. Prefer light and translucent curtains


When choosing curtains, prefer fine and translucent fabrics. They allow light to pass through without completely blocking ventilation, creating a more illuminated and ventilated project.

10. Opt for open doors and partitions


Louvered panels, cobogós, and sliding doors with slats are alternatives that guarantee the separation of projects without compromising air circulation. These elements serve as decorative and practical solutions for those who wish to improve ventilation.
