Putkiläpivienti

Putkiläpivienti refers to the process and components used to pass pipes or conduits through walls, floors, ceilings, or other structural elements. Its primary purpose is to create a sealed and secure passage for pipes, preventing leakage, maintaining structural integrity, and offering protection against fire and water. This is essential in buildings for plumbing, heating, ventilation, and electrical systems.

A typical putkiläpivienti system includes a casing or sleeve, sealing materials, and often a firestop. The casing, usually made of metal or plastic, is installed in the opening before the pipe is passed through. After the pipe is in place, the remaining space between the pipe and the casing is sealed with materials like mineral wool, expanding foam, or specialized sealants. These sealants are crucial for preventing the passage of air, water, and pests.

In fire-rated constructions, putkiläpivienti plays a critical role in maintaining the fire resistance of the structure. Firestop systems are integrated into the läpivienti to compartmentalize the building and prevent the spread of fire and smoke through the openings. These systems are designed to expand when exposed to heat, sealing the gap and blocking flames and smoke. Proper installation and selection of appropriate putkiläpivienti components are vital for safety, building codes, and long-term performance of building services.
