lasitusyksikkö

Lasitusyksikkö is a Finnish term that translates to "glazing unit" or "insulating glass unit" in English. It refers to a sealed assembly of two or more panes of glass separated by a spacer bar and filled with air or an inert gas. This construction is commonly used in modern windows and doors to improve thermal insulation and reduce noise transmission.

The primary purpose of a lasitusyksikkö is to enhance energy efficiency. The air or gas trapped between the glass panes acts as an insulator, reducing heat transfer between the interior and exterior of a building. This helps to keep buildings warmer in winter and cooler in summer, leading to lower energy consumption for heating and cooling. In addition to thermal insulation, lasitusyksiköt also provide acoustic insulation, dampening sound from the outside environment.

The spacer bar plays a crucial role in maintaining the integrity of the unit. It is typically made of aluminum or a thermally improved material and contains a desiccant to absorb any moisture within the sealed space, preventing condensation from forming between the panes. The edges of the lasitusyksikkö are sealed with specialized compounds to ensure the unit remains airtight and watertight.

Lasitusyksiköt can be manufactured with various types of glass, including tempered, laminated, or low-emissivity (low-e) glass, depending on the specific performance requirements. The evolution of glazing technology has led to increasingly sophisticated lasitusyksikkö designs that offer enhanced insulation, safety, and aesthetic options for architectural applications.
