What windows and patio doors to choose for an open space?

Open space areas are gaining increasing popularity in interior architecture—not only in modern single-family homes but also in apartments, offices, and lofts. People are increasingly opting for such solutions because open spaces positively impact the comfort of being in a room, allowing better use of daylight and providing more design possibilities. In such areas, windows become a crucial element, not only providing natural light but also contributing to the room’s aesthetics and functionality.

Selecting the right windows and patio doors for open spaces involves considering several key aspects. Windows and patio doors in these interiors should not only let in ample light but also create an effect of openness, harmony with the surroundings, and a seamless connection between the interior and the exterior. In this article, we’ll explore how well-chosen windows can enhance the comfort of using an open space and which types and technical parameters of windows work best in such arrangements.

The role of windows in open space areas

 In open space areas, well-chosen windows play a fundamental role, affecting both the aesthetics of the interior and the comfort of its users. A key element that windows bring to these rooms is access to natural light, which not only boosts well-being but also helps visually enlarge the interior. Large glass surfaces let in more light, making the space feel more open and bright, thus more inviting and functional.

In open interiors that often combine different functions, such as the kitchen, living room, or dining area, windows can act as a boundary between the internal and external zones. They allow residents to enjoy views of the garden, terrace, or even the city skyline, adding character to the space and creating a unique sense of connection with the surroundings. For those who value contact with nature, windows become not just a source of light but also a kind of artwork that changes with the seasons and diverse weather conditions.

Appropriate windows can also improve the functionality of open spaces, especially when designed to ensure smooth communication between the indoor and outdoor parts of the building. Sliding doors, with their wide panels and large surface area, allow easy access to the terrace or garden, which is particularly useful during social gatherings or family events. This solution makes open space even more practical, enhancing the functionality of the interior to its maximum potential.

Ultimately, windows in open spaces not only ensure adequate light but also influence the interior’s aesthetics. Large, modern glass panels with simple frames give interiors a minimalist look, which is increasingly appreciated in contemporary architecture.

Types of windows suitable for open spaces

Choosing the right type of windows in an open space is crucial since different types of windows can provide different visual and functional effects. Properly selected windows can create a sense of spaciousness, better lighting, and a more seamless connection with the surroundings. Below are the most commonly chosen types of windows ideal for such settings.

Sliding doors

They are highly practical and an excellent choice if the open space is connected to a terrace, balcony, or garden. They don’t take up extra space when opened, making them convenient to use. With their large panels, sliding doors can create a smooth transition between the interior and the outdoor area, which is particularly valuable during the warmer months when the terrace or garden is often used. Thus, sliding doors expand the open space area and further integrate it with the surroundings.

Corner windows

Another interesting solution, especially well-suited to larger open spaces, is corner windows. Placed at the junction of two walls, these windows allow light to enter from two sides, further illuminating the interior and emphasizing its open character. Beyond functionality, corner windows are also a unique decorative element, giving the interior a modern and stylish appearance. They make the space more dynamic, with daylight entering from different angles, creating a fully illuminated effect.

Fixed windows

Fixed, non-opening windows are gaining popularity in open space designs. These windows lack the function of opening, which allows for larger glass surfaces and thin frames that give the interior a modern, minimalist character.

Although they do not provide ventilation, fixed windows can be an excellent addition to spaces where aesthetic qualities and high levels of daylight are crucial. They are often used in combination with other windows that offer opening and ventilation functions.

Key technical parameters of windows in open spaces

Choosing windows for an open space requires considering several key technical parameters that affect the comfort, functionality, and energy efficiency of the entire interior. These spaces are characterized by large glass surfaces, so it is essential that the windows are suitably adapted to heavy use and different weather conditions.

Optimizing thermal insulation

It is one of the most important technical parameters to consider when selecting windows for open space areas. Large glass surfaces can lead to heat loss in winter and excessive room heating in summer if the windows lack proper insulation properties. The U-value should be as low as possible to reduce energy loss and ensure year-round thermal comfort indoors. Modern aluminum and PVC windows feature high insulation performance, helping to minimize heating costs in winter and air conditioning costs in summer.

Enhancing sound insulation

This is especially important if the open space is near busy streets, industrial areas, or other noise sources. Proper sound insulation affects the comfort of staying in the room and helps create a friendly, peaceful environment for working, relaxing, or spending time with family. Choosing windows with an enhanced level of sound insulation is beneficial, particularly for large glass surfaces that are more susceptible to outside noise penetration. An important indicator in this regard is the sound insulation rating Rw—the higher it is, the better the noise reduction.

Durability and ease of maintenance

Resistance to damage and ease of maintenance are other factors that are particularly significant for large windows in an open space. Aluminum and PVC windows are highly resistant to atmospheric conditions such as rain, wind, and UV radiation, making them durable and corrosion-resistant. This ensures that the windows will look aesthetically pleasing and perform well for many years without frequent repairs or maintenance. The surfaces of windows made from these materials are also easy to clean, which is crucial for large glass areas that require regular upkeep.

Suitable technical parameters for windows in an open space guarantee that the interior will be functional, comfortable, energy-efficient, and safe. Therefore, it is worth paying attention to these aspects when choosing windows to ensure long-term satisfaction with the space’s usability and high-quality daily living conditions.

Materials for windows and patio doors suitable for open spaces

The choice of material for window frames plays a key role in designing an open space, as it affects the durability, aesthetics, and technical parameters of the windows. In such interiors, aluminum or PVC windows are most often chosen, as they fit perfectly into modern styles and provide high functionality.

Aluminum windows and patio doors

For large glass surfaces characteristic of open spaces, aluminum is an ideal material. Its strength allows for thin frames, maximizing the glazed area and letting in more light, fully enhancing the visual potential of the interior. Additionally, aluminum windows offer high resistance to weather conditions such as rain, snow, and intense sunlight, making them exceptionally durable and low-maintenance. Their modern appearance complements minimalist designs, and a wide range of colors makes it easy to match them with various interior aesthetics.

PVC Windows and Patio Doors

Another popular material, PVC, is perfectly suited to open spaces due to its properties. Lightweight, moisture-resistant, and easy to clean, PVC frames offer a significant advantage for large windows. The excellent insulation properties of PVC windows help maintain optimal indoor temperatures throughout the year, ensuring comfort in open spaces while reducing heating and cooling costs. Additionally, modern PVC windows come in various colors and finishes, allowing them to complement interior styles, with options that mimic natural materials to further enrich the room’s aesthetics.

Window frame colors and open space aesthetics

The color of window frames plays a crucial role in designing open space areas, influencing the overall look of the interior and its aesthetic coherence. Choosing the right frame color should be well-thought-out, as it can significantly impact the perception of the entire space, creating a sense of harmony, elegance, or dynamic contrast.

Neutral colors like white, gray, and anthracite are highly popular in open space designs because they add modernity and a minimalist character to the interiors. White frames visually enlarge the space and fit well in bright, light-filled rooms, creating an effect of lightness and subtle integration with other finishing elements. On the other hand, gray or anthracite frames add elegance and can create a slightly more pronounced, industrial vibe. These shades pair well with concrete, metal, and other materials typical of loft-style interiors.

Contrasting frames can become a distinctive design feature, adding dynamic character to the space. Opting for dark frames in bright interiors can create a striking contrast that attracts attention and adds expressiveness to the room. This arrangement can be particularly effective in large open spaces where large glass surfaces and bold frames become integral parts of the design. Contrasting frames can also give the space a unique character, making the interior stand out with a more artistic touch.


Frames matching the wall color are an interesting option for those who want to achieve a seamless effect and visually enlarge the space. By choosing frames in a color similar to the walls, windows can almost disappear, blending into the background and enhancing the sense of openness. This solution works well in minimalist arrangements that emphasize simplicity of form and a lack of unnecessary decorative elements.

Benefits of well-chosen windows and patio doors for open spaces
