Are tilt‑turn windows measurably tighter in blower‑door tests than North American casements, and is maintenance worse?

Tilt-turn windows usually do better in blower door tests than regular casement windows in North America. This is because their seals press the window tightly against the frame at many spots. For houses built to be super energy efficient, this can make a real difference in lowering ACH50 scores.
Yes tilt turns usually seal tighter in blower‑door tests, but they need more careful maintenance than typical North American casements.
Tilt-turn windows tend to perform better in blower-door tests due to their airtight sealing system and multi-point locking mechanism, which provide excellent weather resistance and prevent air leaks.
Yes, tilt-turns often score tighter in blower-door tests due to continuous multi-point seals, but hardware is more complex and needs periodic lubrication/adjustment, so maintenance can be slightly higher.
Yes
Tilt‑turns are usually tighter in blower‑door tests due to multiple compression seals, but maintenance is higher: hinges, hardware, and gaskets need regular inspection and adjustment.

Yes,tilt-turns often test tighter due to continuous multi-point compression seals, but gains shrink if both are high-quality and well-installed.
Maintenance is higher: more hardware points, precise adjustment needs, and gaskets that must stay clean and lubricated.
Yes
Tilt-and-turn windows are generally measurably tighter in blower-door tests and offer easier maintenance compared to North American casement windows. Their unique design and sealing mechanisms contribute to superior airtightness and ease of cleaning from the inside
