The choice of windows is a crucial part of a complete home solution. It affects space usage, indoor climate, and the amount of natural light. Which types of windows are suitable for a modern home, and what materials should you choose? Aru Grupp offers a wide range of solutions: inward‑ and outward‑opening windows, double‑sash windows, and vertically sliding English windows. Windows are available in both wooden and wood‑aluminium.
➡️ Inward-Opening Windows
Inward‑opening windows provide a classic and practical solution. Wooden windows bring warmth and timeless elegance to the interior. Wood‑aluminium windows combine the warmth of wood inside with the weather resistance and durability of aluminium outside, ensuring long-lasting performance. These windows open inward and are easy to maintain – glass surfaces can be cleaned from the inside. They also allow for larger glass areas, bringing more natural light into the room.

➡️ Outward-Opening Windows
Outward-opening windows are ideal where indoor space must remain free, such as in narrow rooms or near furniture. Wooden windows provide weather resistance suitable for Scandinavian climates and slim profiles. Tthat allow more light into the room. Wood-aluminium windows add exterior durability and low maintenance while retaining the warm appearance of wood inside. The outward-opening mechanism allows flexible use of interior space.

➡️ Double-Sash Inward- and Outward-Opening Windows
Double-sash windows are an ideal solution for renovating historic or heritage buildings where maintaining the original architectural style is important. These windows offer both historic authenticity and modern comfort. The double-sash design allows regulation of airflow and light according to needs and provides the choice of opening either the inward or outward frame.

➡️ Vertically Sliding / English Windows
Vertically sliding English windows are an elegant, space-saving solution. The sashes move up and down, allowing smooth operation without needing free space in front or behind. English windows add a classic character to the building while maintaining a bright and open feel, making them ideal for historic and traditional homes.
