Finnfoam Tulppa Armored Extruded Polystyrene with Half Density for Wet Spaces

Finnfoam has created the innovative moisture-resistant sheets Tulppa. These sheets are used in damp spaces and serve as both waterproofing and construction panels. The sheet consists of three layers: inside is the Finnfoam insulation material, which has a uniform structure formed by closed pores, making it moisture-resistant and preventing the growth of mold. The exterior of the Tulppa sheet is covered with a special durable layer of Sika cement with a fiberglass mesh. Thanks to the patented installation system, Tulppa sheets are easy and quick to install. An experienced specialist using Tulppa sheets can easily prepare a wall area of 10-15 m2 for finishing in just an hour. The sheets are lightweight and can be lifted by one person.

The Finnfoam insulation material inside the sheets performs waterproofing, thermal insulation, and also acts as a vapor barrier. Since the material does not absorb water and has high pressure resistance, Finnfoam is an excellent material for waterproofing sheets.

The core of the Tulppa insulation sheets is Finnfoam extruded polystyrene (XPS), which is moisture-resistant, mold-resistant, and has excellent thermal insulation properties. The production of Finnfoam sheets does not involve the use of environmentally harmful materials, so Tulppa sheets are assigned the highest M1 emission class based on the amount of chemical compounds released into the environment. The outer surface of Tulppa sheets is made of a special highly durable Sika cement mixture reinforced with a fiberglass mesh. The sheets can be installed on various types of surfaces.

Easy installation, easily shaped and processed: Easily processed and cut, easily installed even in narrow spaces, Tulppa sheets can save several working days. The innovative patented horizontal installation method makes it easier to install the sheets, and the edge profile of the sheets ensures that no water passes through the joints. The sheets can be easily cut with manual or electric tools, giving them the desired shape and size.

Significant time and effort are saved because there is no need to apply a separate moisture-resistant layer on the sheets and wait for it to dry. Tiles can be directly glued to Tulppa sheets the next day after installation.
