Main Door With an Opening Window: Ventilation Without Opening the Door
A main door with an opening window lets fresh air and daylight into the house while the door itself stays shut and locked. On the Aura Window Door, the window is set into a galvanised steel door, glazed with toughened safety glass, and opens separately from the door leaf. You get airflow at the entrance without leaving the door open.
How does a window in the door give ventilation without opening it?
A normal main door has two positions: shut, with no air, or open, with no security. A window door adds a third. The leaf stays closed on its Single Multi Lock, and only the glazed window opens. Air moves through the window frame while the door frame, the lock and the rest of the leaf stay as they are.
This suits homes where the entrance is the main source of cross-ventilation, such as a flat with one external door, or a balcony door that faces the breeze. The glass also lets light into the entry when the window is shut.
Window door or fixed glass door: which one do you need?
Our Aura range also includes glass doors such as Aura AU11 and Aura AU31. On those pages the glass panel brings in light and openness, but no opening window is described. If you need air as well as light, the window door is the model that offers it.
| Point | Aura Window Door | Aura glass doors (AU11 to AU61) |
|---|---|---|
| Window opens separately from the door | Yes | Not described on the pages |
| Glass | Toughened safety glass | Varies by model, from impact-resistant toughened to decorative glass |
| Body and frame | Galvanised steel, 100mm frame | Galvanised steel, 100mm frame |
| Lock | Single Multi Lock | Single Multi Lock |
| Surface | Anti-rust exterior, termite-proof coating | Anti-rust and anti-termite protection |
| Finish | Wood-finish options | Varies by model |
If you are choosing between glass finishes rather than an opening window, our guide to the glass in each Aura model compares all six glass doors.
Where does a door with an opening window work best?
The Aura Window Door page describes it as an entry door or a balcony door, for residential and commercial use, and names high-rise flats, villas and independent houses as places it is fitted. In practice it earns its place wherever you want air at the doorway but do not want to leave the door open:
- a flat entrance that opens onto a common corridor;
- a balcony or terrace door you keep locked;
- a front door in a house where the entrance faces the breeze.
Wood-finish options and clean window lines are offered so the door can match the rest of the facade.
Is a main door with a glass window secure?
The window is glazed with toughened safety glass, and the leaf around it is galvanised steel on a 100mm frame. The door locks with a Single Multi Lock system, and the page lists a termite-proof coating, an anti-rust exterior and fire resistance features. The glass is the part to discuss with us: ask what glass thickness and window lock come with your door, as neither is printed on the page.
What should you confirm before you order?
- The width and height of the door opening in millimetres. The page offers size customisation but prints no standard sizes.
- The size of the window and which side it opens to, so it clears furniture, grilles and a safety door if you have one.
- The glass thickness and the lock fitted to the window.
- The wood finish you want on the door.
- Installation. Megastar offers professional installation and after-sales service with this door.
