Attic Pleated Blind

Solving the Sloped and Vertical Windows Together in the Attic

The attic carries two types of openings. The sloped window on the roof plane and the vertical window on the gable wall. On the sloped glass a standard blind sags. The railed tensioning mechanism keeps the fabric locked along the slope, no sagging occurs even when open. On the vertical gable window a normal vertical unit is used.

The roof window is hard to reach. It may need reaching over the bed or furniture. In the hand-pushed control the operating handle reaches toward the window. If access is hard, an extension rod or motorised control steps in. The decision is provided per the usage frequency. On a glass opened a few times a day the motorised option is practical.

The attic’s thermal character affects the blind. The sloped glass takes direct sun in summer, it is the room’s hottest surface. Sunscreen or blackout fabric stops the heat entry at the glass surface. The open system at night lets the attic air.

The bed is generally placed under the slope in the attic. The sloped glass above the head drops the street light directly onto the bed at night. The blackout-fabric railed system cuts this light line. This is the only solution for the sloped glass.

The roof-window brand chooses the mounting decision. A common brand’s case measurement is standard, it has ready hardware. On custom-production joinery a universal rail mechanism is made. The brand and the slope angle are the measurement form’s mandatory field.

Dust build-up is fast in the attic. Once-a-year brush cleaning on the upward-facing rail channel is enough. The fabric is wiped with a damp cloth. No water touches the rail mechanism.

Access to the roof window at the stair head is from the stairwell. The unit position must be within hand reach. On the sloped glass at a high level a rod extension or the motorised control type is considered. The access line is marked at measurement.

In summer the attic accumulates heat. The closed unit cuts the sun load at the glass plane and balances the difference with the lower floor. In winter the same layer contributes to the roof insulation. The attic blind works all year.

The vertical and the sloped window want different mechanisms. On the vertical joinery a standard unit, on the sloped roof glass a railed system is produced in the same project. Every joinery is marked with its slope angle, the two systems are cut from the same fabric.
