What a dilemma... You know those long, narrow kitchen windows? In older buildings, even the windows just don't go unnoticed 🫠 💡 Why did I reduce the size of the kitchen window? ▸ The aluminum sash had its own unique vibe(?), but I had to replace it. I felt that switching to standard sashes would make the thick frames look stifling. ▸ I decided to make this because I wanted to secure a little more tile surface area to make the kitchen mosaic tiles stand out. 📍 Things worth checking together ▸ To reduce concerns about condensation, I also meticulously carried out ‘insulation work’ between the fixed window and the wooden partition wall. ▸ Since system windows have a small airflow area, if ‘ventilation’ is important to you, consider standard sliding sashes as well. Still, I'm sharing some great tips that will elevate the details if you take them into account.
