Frequently Asked Questions
What is a tilt and turn window?
A single sash that can either tilt inward from the top (for secure ventilation) or swing fully inward from the side (for full opening or cleaning). One hardware set, two functions, controlled by handle position.
Is this suitable for high-rise buildings?
Yes. The tilt position offers safe, restricted ventilation ideal for upper floors and homes with children. Egress clearance in the turn position meets most residential codes.
What is the thermal performance of this window?
Tilt-and-turn frames typically use a robust thermal-break profile.
Can I clean the exterior from inside?
Yes. In the turn position the sash rotates fully inward, giving safe indoor access to both sides of the glass without needing a ladder or exterior scaffolding.
Are they available with concealed hinges?
Yes. Concealed hinge hardware is available for a cleaner exterior look. Standard configurations use exposed hardware for easier maintenance.
