The two common roof window styles open in different ways, and that changes how you use the room. Here is how to decide which suits your house.
VELUX and similar roof windows come mainly as centre-pivot or top-hung. Both let light into a loft room, but they behave differently when opened. On the modern homes of Emersons Green, with their pitched concrete-tile roofs, the right choice depends on room height, roof pitch and how you use the space.
How a centre-pivot window works
The sash pivots around a point near the middle of the frame, so the top swings outward and the bottom swings in. It opens wide for ventilation, and you can turn it fully round for cleaning the outside glass from inside. The handle sits at the top, which suits a lower window set well up the slope. It is useful in a room where the window is out of arm's reach, since you can clean it from inside.
How a top-hung window works
A top-hung window is hinged at the top and opens outward from the bottom, like an awning. The handle is at the bottom, so it is easy to reach on a taller window. It usually gives a clear view out and works well where you want a window that stays out of the way of furniture. Many people like the clear outlook.
- Hinged at the top and pushed out from the bottom
- Handle at the bottom edge for easy reach
- Good for rooms where the window is set high
- Offers a clearer outlook when open
What decides the choice
Position and pitch matter most. A lower pitch can suit one style better than the other, and the height of the sill above the floor affects which handle is easier to use. The size of the room, furniture, and whether you want to look out while seated also come into it. We discuss this room by room.
What fitting involves
Either type needs a flashing kit matched to the roof covering. Rafters may need trimming and doubling up around the opening, and the lining, insulation and vapour control are fitted to keep the room warm and dry. Fitting a new opening may need planning or Building Regulations checks — we advise before work starts. We check the opening dimensions on site before ordering.
Choosing sensibly
Think about how you will use the room. For a bedroom or a study where you sit and look out, one style may suit; for a landing or a stairwell, another. We bring the options, explain how they open and help you decide. Any window is only as good as its installation, so flashing and sealing matter more than the label.
Frequently Asked Questions
Which style is better for ventilation?
Both ventilate well. A centre-pivot opens wide for a good flow of air, and top-hung windows can be opened part way and still keep rain out. The choice depends on position and how you want to use the room.
Can a top-hung window replace a centre-pivot?
Often yes, but the opening size and flashing kit must match. We measure the existing opening and tell you what is possible, and whether any change to the roof covering or lining is needed.
Do I need a specific window for a loft conversion?
Not always, but a loft room usually needs enough openable area and escape routes. A loft conversion may need planning or Building Regulations checks — we advise before work starts. We help you pick windows that fit the roof and the room.
