Palosuojalasit

Palosuojalasit, often translated as fire-resistant glass or fire-rated glass, are a specialized type of safety glass designed to withstand fire for a specified period. This resistance is achieved through various manufacturing processes and material compositions, which can include multiple layers of glass with intumescent interlayer materials or specific chemical treatments. When exposed to high temperatures, these interlayers expand and form a hard, opaque crust that insulates against heat and prevents the passage of flames and smoke.

The primary function of palosuojalasit is to compartmentalize a building during a fire, slowing its spread and providing occupants with more time to evacuate safely. They are crucial safety components in building construction, particularly in areas requiring fire separation, such as stairwells, escape routes, and fire-rated walls and doors. The performance of palosuojalasit is rated according to international standards, indicating the duration and integrity they maintain under fire conditions, often denoted by classifications like E, EW, and EI.

Beyond fire resistance, palosuojalasit can also offer other benefits, such as sound insulation and impact resistance, depending on their specific construction. They are available in various forms, including clear and obscure finishes, and can be incorporated into different glazing systems. The selection and installation of palosuojalasit must adhere to strict building codes and regulations to ensure their effectiveness in a fire event.
