Yes, passive doors usually noticeably reduce drafts and retain heat better, so the difference is perceptible, especially if your old doors are leaky.In practice, the biggest improvement is felt around the frame and threshold, where air used to seep through. Additionally, the temperature inside the home becomes more stable near the entrance, without sudden drops of cold air. However, it’s still important to choose a good model and pay attention to build quality, as this also has a strong impact on the final result.
