What sets our tilt & turn windows apart in Welwyn Garden City.
Dual-Action Opening
Turn the handle 90° and the sash tilts inward top-first for secure ventilation. Turn it 180° and the sash swings fully inward for cleaning and egress.
Safe Interior Cleaning
Clean the outside of the glass from inside the room — essential for flats, first-floor bedrooms and any window above a driveway or drop.
Doc B Fire Egress
The full 180° turn provides a compliant fire-escape opening — required on habitable rooms above ground floor without another route out.
Continental Sightlines
Flush interior appearance with no protruding handle, ideal for architectural interiors and window seats. Concealed hinges for a clean external look.
Child & Restrictor Safety
Lockable tilt-only position with a security key — ventilation without the ability to accidentally push the sash into a full turn.
PAS 24 Multi-Point Locking
Up to 8 locking points around the sash perimeter. Naturally more secure than a standard casement thanks to the geometry of the mechanism.

- What guarantee covers tilt & turn windows in Welwyn Garden City?

- Can I see recent tilt & turn windows work near Welwyn Garden City?
- Yes — we can share recent tilt & turn windows case studies from across Hertfordshire, including projects in Old Welwyn, Handside and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does tilt & turn windows achieve in Welwyn Garden City?
- Energy-efficient tilt & turn windows installed across Welwyn Garden City, Hertfordshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- When are tilt & turn windows the right choice?
- Above ground floor they are safer to clean, provide a compliant fire escape and make secure ventilation straightforward. They are especially well suited to flats and bedrooms.
- Do they take up interior space when open?
- In tilt mode, the top of the sash intrudes about 100mm — enough for airflow, not enough to catch on curtains or blinds. In full-turn mode the sash swings inward and needs clear space, so we advise against them behind kitchen sinks.
- Can children open them?
- The tilt position is lockable with a key, so children can't force a full turn. This is standard on any tilt & turn we fit above ground floor.
