Tuulensuojalevyjä

Tuulensuojalevyjä, often translated as wind barrier boards or windproofing panels, are building materials used to protect structures from wind and air infiltration. Their primary function is to reduce the amount of air that passes through the building envelope, thereby improving energy efficiency and thermal comfort. These boards are typically installed on the exterior of a building, beneath the main cladding material.

The composition of tuulensuojalevyjä can vary. Common materials include wood fiber, gypsum, or specialized composite materials designed for durability and weather resistance. They are designed to be permeable enough to allow moisture vapor to escape from the wall cavity, preventing condensation buildup, while simultaneously blocking drafts and larger air currents. This breathability is crucial for maintaining the structural integrity of the building and preventing mold growth.

Installation involves overlapping the panels and taping the seams to create a continuous barrier. This process, along with proper sealing around windows, doors, and other penetrations, is essential for effective windproofing. By minimizing air leakage, tuulensuojalevyjä contribute to lower heating and cooling costs for a building. They also play a role in acoustic insulation by reducing the transmission of external noise. In colder climates, they are a vital component of a well-designed wall system, working in conjunction with insulation to maintain a stable indoor environment.
