Vaahtoseinämän

Vaahtoseinämän, often translated as foam wall or foam insulation wall, refers to a construction technique or a material used in building insulation. It generally involves the application of a foamed material, typically polyurethane foam, directly onto a surface to create an insulating barrier. This method is known for its ability to create a seamless, monolithic layer of insulation.

The application process usually involves spraying a liquid mixture that rapidly expands and solidifies into a rigid foam. This expansion allows it to fill cavities and irregular shapes, providing excellent thermal resistance and air sealing properties. Vaahtoseinämän is often used in both new construction and retrofitting projects to improve energy efficiency by reducing heat loss or gain.

The benefits of using vaahtoseinämän include its high R-value per inch, its ability to act as a vapor barrier, and its structural reinforcement capabilities in some applications. However, potential drawbacks can include the cost of specialized application equipment and the need for professional installation to ensure proper curing and performance. Environmental considerations related to the blowing agents used in some foam formulations are also a factor in its use.
