Vedonpoisto

Vedonpoisto is a Finnish term that translates to "draft removal" or "air sealing." It refers to the process of identifying and eliminating unwanted air infiltration into a building. This is a crucial aspect of energy efficiency, as drafts can lead to significant heat loss during colder months and heat gain during warmer months, increasing heating and cooling costs.

The primary goal of vedonpoisto is to create a continuous air barrier around the building envelope. This barrier prevents conditioned indoor air from escaping and unconditioned outdoor air from entering through gaps and cracks in the structure. Common areas where drafts occur include around windows and doors, electrical outlets, plumbing penetrations, attic hatches, and where different building materials meet.

Methods for vedonpoisto vary depending on the source of the draft. Sealing small gaps and cracks can be achieved using materials like caulk, spray foam insulation, or weatherstripping. For larger openings or more complex issues, specialized tapes, membranes, or even structural modifications might be necessary. A thorough inspection, often involving tools like a smoke pencil or a blower door test, is typically performed to pinpoint the exact locations of air leaks before remediation begins.

Beyond energy savings, effective vedonpoisto also contributes to improved indoor comfort by eliminating cold spots and drafts. It can also help prevent moisture problems, such as condensation and mold growth, that can arise when warm, moist indoor air comes into contact with cold surfaces. In essence, vedonpoisto is a fundamental practice in modern building construction and renovation aimed at creating healthier, more comfortable, and energy-efficient living and working spaces.
