Roof Windows in Białystok — Light and Air in the Loft

Why does a roof window give more light than a wall window?

A roof window lets in more natural light than a wall window of the same size, because it looks straight up at the sky rather than at a neighbouring building or a tree. In a liveable loft that is the difference between a cramped, dark box and a proper room you can work, sleep and relax in.

The second thing is air. Under the slopes it quickly gets stuffy in summer, because heat gathers at the top of the room. A roof window lets it out from there — warm air escapes through the top while cooler air comes in. On SKYLIGHT PREMIUM the handle and trickle vent sit at the bottom of the sash, so you can open the window in the vent position without reaching up to the ridge of the roof.

If you are planning a loft from scratch, it is worth thinking about light and ventilation together with the rest of the joinery — well-chosen uPVC windows in the knee walls and roof windows above them give the best result. Book a free survey and we will match the layout and size of the windows to the pitch of the roof.

SKYLIGHT PREMIUM — specification

SKYLIGHT PREMIUM is a roof window built on a uPVC profile reinforced with galvanised steel, designed for durability and a tight seal in demanding roof conditions. Below are the key figures, and beneath them what they mean in practice.

• uPVC profile reinforced with galvanised steel — resistant to dirt and ageing, with the steel improving the structural rigidity of the window.
• Polyester-lacquered flashing — mill-coated, with a weather-resistant polyester finish.
• Handle and trickle vent at the bottom of the sash — convenient opening and ventilation without reaching up to the ridge of the roof.
• Adjustable sash — the sash position can be adjusted for even pressure and a tight seal.
• Full opening with a brake lock — the sash can be opened wide and safely held in the chosen position.
• Triple sealing — a system of three seals provides very good protection against water and draughts.
• Uw = 1,5 W/m²K — the heat-transfer coefficient of the whole window.

Warm fitting in the roof — snow, ice and water off the slope

A roof window works in harsher conditions than a wall window. It lies at an angle, so snow, ice and water running off the slope collect on it and around it. That is why the tightness and warmth of the loft depend not only on the window itself, but above all on how it is set into the roof.

The key element here is the flashing — the trim that joins the window to the roof covering, channelling water around the frame and stopping it getting in under the tiles. On SKYLIGHT PREMIUM the flashing is polyester-lacquered, so it stands up to the weather well. Just as important is what is known as warm seating: continuous insulation and a vapour barrier around the frame, with no thermal bridges where, in Podlasie frosts, moisture condenses and forms ice.

We will match the size and opening style of the window to the pitch of the roof and the height of the room, so that the bottom handle is within easy reach and the window can be operated normally. We carry out the fitting with care for the seal, because that is what decides whether the loft stays dry and warm for years.

Sun shades — so you can sleep in summer

A roof window that is a blessing in winter can heat the loft up considerably in summer — the sun shines into it for most of the day. That is why it is worth choosing sun shades for roof windows right away; they limit the heat build-up and let you darken the bedroom.

In practice, blinds and awnings fitted on the outside or the inside of the window work well — external ones stop the heat most effectively before it enters the room, internal ones provide convenient blackout and privacy. It is best to plan them together with the window, so the guides and fixings match the sash. Just as with vertical windows, where you reach for roller blinds or venetian blinds, in the loft it is about the same thing: control over light and temperature.
