Tilt-Only Windows (Hopper Windows) USA | From $280 per windows

Why Choose Tilt-Only Windows

Controlled, secure ventilation — tilts inward from the top for airflow without fully opening the window; ideal for basements, ground floors, and rooms where security matters.
Easy interior cleaning — both sides cleaned from inside, no ladder needed.
Energy efficiency — multi-chamber profile and tight seals reduce drafts and heating/cooling costs.
Enhanced security — locked shut except for a controlled tilt gap, reducing break-in risk while still allowing airflow.

Hopper vs. Awning Windows: What's the Difference?

People often confuse hopper and awning windows — both tilt, but in opposite directions.

	Hopper (Tilt-Only)	Awning
Hinge position	Hinged at the bottom, tilts inward at the top	Hinged at the top, tilts outward at the bottom
Rain protection	Good — opens inward, no rain intrusion	Excellent — acts as an awning, sheds rain even when open
Best placement	Basements, ground-floor rooms, bathrooms	Above doors, higher wall sections, combined with fixed windows
Security	Compact opening, hard to access from outside	Compact opening, hard to access from outside

Bottom line: if the window needs to shed rain while open, awning wins; if you want the airflow directed inward and away from furniture, hopper (tilt-only) is the better fit.

Frequently Asked Questions

What is a hopper window?
A hopper window is hinged at the bottom and tilts inward at the top — the U.S. term for what's known in Europe as a tilt-only window. It provides controlled ventilation without opening like a door.
What's the difference between a hopper and Qan awning window?
See comparison above — hopper tilts inward at the top, awning tilts outward at the bottom.
Where should I install a tilt-only/hopper window?
Basements, ground-floor rooms, bathrooms, and anywhere a full-swing window isn't practical or safe.
Can a hopper/tilt-only window be used as a basement egress window?
No — hopper and tilt-only windows have a limited opening size and are not designed to meet egress code requirements. For a basement escape window, see our
Is it safe for a child to open one fully, like a door?
No — unlike tilt-and-turn windows, a tilt-only/hopper window only tilts inward at a controlled angle and does not swing open like a door, which makes it a safer choice above counters or in kids' rooms.
