Lasitusten

Lasitusten is the Finnish term for glazing in construction, the process of fitting glass panes into openings or covering surfaces with glass. It includes installing windows, exterior curtain walls, skylights, and interior glass partitions, as well as reglazing and repair work. The scope covers both traditional single-pane glazing and modern insulating glazing units used to improve energy efficiency and comfort.

Common materials used in lasitusten include various glass types such as annealed, tempered, laminated, and insulated units; frame materials like wood, aluminum, and uPVC; and sealing systems, spacers, and coatings such as Low-E for improved thermal performance. The choice of materials depends on factors such as structural requirements, climate, acoustics, and desired aesthetics.

Techniques in lasitusten involve careful measurement, frame preparation, and the use of appropriate sealants, glazing beads, or mechanical fasteners. For safety, glazing is often tempered or laminated in hazardous locations. Energy performance is enhanced through properly designed insulating glass units, airtight seals, and correct installation to minimize thermal bridging and drafts; coatings can provide UV protection and glare reduction.

Applications span residential, commercial, and industrial sectors, including new construction, renovations, and retrofit projects. Storefronts, partition walls, and industrial façades are common contexts for glazing work, as are specialized systems for dynamic or curved glazing. Maintenance tasks include cleaning, inspecting and replacing seals, and replacing damaged panes to prevent leaks and ensure long-term performance.

Lasitusten is typically governed by building codes and safety regulations, including requirements for glass strength, breakage resistance, and, where applicable, fire safety glazing. Ongoing advances in glazing technology focus on improving energy efficiency, durability, and integration with architectural design.
