Finnfoam Oy has developed a new type of waterproofing board for wet rooms called Tulppa®. Tulppa® (Finnish for ‘plug’) is a horizontal-installation wet room insulation board that simultaneously functions as a building board and waterproofing material. The core of the board is closed-cell, waterproof and mould-proof Finnfoam insulation material, while the surface layer is durable Sika special purpose cement mortar.
Thanks to the patented installation system, installing Tulppa boards is quick and easy. Using Tulppa boards, a professional builder can easily complete 10 to 15 m² of wall surface ready for tiling in an hour. Tulppa boards are easy to install, cut to shape and handle. The innovative, patented horizontal installation method makes installation work easier, and matched edge profiles ensure that all joints are waterproof. As no brush-applied waterproofing agents and drying periods are required, the Tulppa boards save significant amounts of time. Tulppa wet room structures can be ready for tiling in less than a day!
The Tulppa board is also the ideal building material for wet room structures such as shower walls, shelves, benches or panelling e.g. for bathtubs. It can also be used to build these special structures in existing wet rooms.
