lasituskohtaa

Lasituskohtaa is a term used in Finnish architecture and construction referring to the glazing interface or joint where a glass element meets a frame or other supporting structure. The term describes the critical area that carries the glazing, accommodates movement, and provides weatherproofing and airtightness.

The concept applies to both individual window units and larger façades, such as curtain walls, skylights, and glass façades. It encompasses the components and connections that seal and secure the glass within its frame and that ensure proper drainage and moisture management.

Components and materials commonly involved in the glazing interface include sealants, gaskets, spacers, and glazing beads. The choice of materials, such as silicone or polyurethane sealants and EPDM gaskets, influences service life, thermal performance, and airtightness. The interface may also involve mechanical fasteners or fittings for load transfer and containment.

Function and performance considerations focus on water and air tightness, thermal insulation, acoustic reduction, and resistance to wind and rain loads. The glazing interface must allow controlled movement due to thermal expansion and structural loads, while maintaining a durable seal. Improper installation or aging seals can lead to leaks, condensation, or reduced energy efficiency.

Design and maintenance practices address compatibility between glass and frame materials, edge seal geometry, drainage routes, and ease of inspection. Maintenance generally includes periodic cleaning and resealing to preserve performance. In practice, lasituskohtaa is governed by national building regulations and international glazing standards that cover installation methods, performance criteria, and testing.
