Types of window; window for more light
Short answer
Types include fixed, casement, double-hung, sliding, pivoted, louvered, awning, hopper, bay, bow, dormer, corner, clerestory, skylight. Bay windows admit most light as they project out receiving light from three sides; clerestory and skylights also bring light from roof. Fixed windows with full-height glass maximize light but need separate ventilation. Window area should be at least 1/10 floor area per code.
List types of window. In your opinion which type of window is suitable for admittance of more light inside the room? Discuss.
Types of windows
| Window | Description |
|---|---|
| Fixed window | Glass fixed in frame, gives only light, no ventilation |
| Casement window | Shutters hinged at the sides, open like doors; most common |
| Double-hung (sash) window | Two sashes slide up and down in a frame with weights |
| Sliding window | Shutters slide horizontally on tracks; aluminium/UPVC |
| Pivoted window | Shutter turns on a horizontal or vertical pivot at the centre |
| Louvered window | Slats (fixed or movable) inclined at 45 degrees; ventilation and privacy |
| Awning window | Hinged at top, opens outward at the bottom |
| Hopper window | Hinged at bottom, opens inward at the top |
| Bay window | Projects outward from the wall in plan; extra space and light |
| Bow window | Curved bay |
| Dormer window | Vertical window projecting from a sloping roof with its own small roof |
| Corner window | Placed at the corner where two walls meet; light and cross ventilation |
| Clerestory window | High-level window above eye level; light and ventilation in tall rooms |
| Skylight | Glass in the roof slope; top light |
Window for more light
A bay window (or a large fixed or corner window) admits the most light because it projects out of the wall and receives light from three sides; the glass area is larger and light comes from different directions. Other good choices are clerestory windows and skylights, which bring light from the roof. A fixed window (picture window) with a full-height glass panel admits maximum light but needs another opening for ventilation.
So for admitting more light, a bay window or full-height glazed casement window is suitable. Window area should be at least 1/10 of the floor area as per building code, and the sill is about 0.9 m high.
