dörrfogar

Dörrfogar is the Swedish term for the gaps and joints around a door. It refers to the space between the door leaf and its frame, the joint between the door frame and the surrounding wall, and, in exterior doors, the gap at the threshold or bottom of the door. In construction practice these gaps are managed with sealing systems to control drafts, moisture and noise.

Typical components include weatherstripping (foam, rubber, vinyl or silicone), door seals or gaskets, door sweeps at the bottom, and caulking or sealants for fixed joints around the frame. The choice depends on whether the door is interior or exterior, the climate, and the desired level of insulation and acoustic performance.

The purpose of well-maintained dörrfogar is to reduce air leakage, improve energy efficiency, prevent moisture ingress and minimize sound transmission. Proper gaps should close when the door is shut while allowing normal operation; components should not impede movement or cause sticking.

Maintenance and assessment involve inspecting seals for wear, replacing worn weatherstrips, ensuring clear clearance around hinge side and top, and resealing joints when needed. Poor or degraded dörrfogar can lead to drafts, higher heating or cooling costs, and, in damp climates, moisture problems or mold risk. Regular inspection is part of routine building maintenance.
