vindueskarme

Vindueskarme, or window sills, are the horizontal ledges at the bottom of a window opening. They exist as interior and exterior elements. The interior sill provides a surface for decoration, plants, or small items, and helps finish the room around the window. The exterior sill is part of the facade, designed to shed water away from the wall and protect the building from moisture.

Materials for vindueskarme vary widely. Common options include wood, natural stone, concrete, brick, metal, PVC, and composite materials. Wood offers traditional warmth but requires sealing to resist moisture; stone and concrete are durable and heavy; metal can provide a slim, modern look; PVC and composites minimize maintenance. Installation typically matches the window frame and wall finish, with attention to insulation, drainage, and moisture management.

Design and installation considerations include proper sizing to support loads and appropriate edge detailing. Exterior sills usually have a slight forward slope to divert rain and may include a drip edge to prevent water from running back into the wall. They are anchored to the window frame and wall structure, and sealed against moisture to prevent infiltration.

Maintenance and variation: Regular cleaning and inspection for rot, cracks, or loose fittings are advised, with resealing or repainting as needed. In historic or regional contexts, vindueskarme reflect architectural style and can range from carved stone or thick timber to tiled or plastered surfaces, influencing both aesthetics and performance.
