The two common roof window styles open in different ways and suit different rooms. Here is a clear comparison, with the Pucklechurch mix of old cottages and later houses in mind.
Picking a roof window sounds like a matter of size and price, but how it opens changes how you use the room. A cottage loft with a low eaves wall and a modern landing under a shallow pitch can need quite different answers. Both styles do the job well when matched properly.
The centre-pivot
A centre-pivot window turns on a central axis, so the lower half swings in as the top swings out. You can clean the outside glass from inside, and the sash sits fairly flat when open. It suits windows set at a comfortable height with room to stand and reach the handle.
Because it opens inwards at the bottom, a centre-pivot window can block the space near it when ajar, so furniture and curtains need thought. We think about the room and what will stand beneath the window. Think about curtains, blinds and furniture before choosing.
The top-hung
A top-hung window is hinged along the top edge and swings outwards from the bottom, a little like a projecting window. It opens higher, giving more headroom and a better view out from a seat or bed. It tends to suit windows near the floor of a loft room.
- Centre-pivot: easier outside cleaning from within
- Top-hung: more headroom and a better outlook
- Centre-pivot: suits windows higher on the slope
- Top-hung: suits low-set windows and knee walls
Old cottages and low eaves
Older stone and brick cottages often have lofts where the roof comes down low at the sides. A window placed low for a view out may suit top-hung, because it opens clear of the sloping ceiling. Where headroom is generous, either style works. We look at the room before recommending one.
Some owners ask for a window that opens fully for escape or large-scale ventilation. Rooms used for sleeping have their own needs, and we talk these through on site and match the window to the use. How the room is used shapes the choice, so the window should follow it.
Dormers, bungalows and infill homes
Bungalow and dormer lofts have different geometry, so the same window can feel different. Later infill houses often have regular pitches, which suit either type. The roof covering decides the flashing kit, while the window type is chosen for how you will live with it every day.
What the fitting involves
Whichever you choose, the opening is cut, rafters are trimmed and doubled up where needed, and the frame is flashed to suit the roof covering. Lining, insulation and vapour control finish the opening inside. It may need planning or Building Regulations checks — we advise before work starts.
Whichever style you pick, a roof window is matched to the roof covering, and the opening is formed with care so water cannot get past. We would rather explain the choice in the loft than sell you a style. The right window is the one that suits the room and the roof.
Frequently Asked Questions
Which type is easier to clean?
Centre-pivot is usually easier because the outer pane turns inwards for you to reach. Top-hung windows can be cleaned from inside only in certain models or positions, so we talk through what you prefer. The choice depends on height and reach.
Which is better for ventilation?
Both open to let air in, and many have a small trickle setting for light ventilation. The better one is simply whichever you will find easy to reach and use, which depends on height. We talk through which suits you.
Can I replace an old window with a different type?
Often yes, though the frame size and flashing may change when the new unit is chosen. We measure the opening first and explain what a different type involves before you decide, so you know the full picture.
