Over the course of its forty-year-long history, Finnfoam has become one of the leading manufacturers of plastics-based thermal insulation solutions. The roots of our thermal insulation competence are embedded into the frozen Finnish soil. Finnfoam Group is known for quality, product development, and reliability.

Our products are designed to meet the needs of our customers in the best possible way. Our strengths in designing and manufacturing thermal insulation products are crystalized as robust experience and novel thinking.

In addition to thermal insulation capacity, particular focuses of our product development and manufacturing include reliability, durability, easy installation, and material efficiency. The production lines for FF-EPS, FF-PIR, and FINNFOAM (XPS) thermal insulation have been designed to ensure good, optimized product characteristics at any thickness and to allow for rapid deliveries.

We are continuously increasing our production capacity, and today our insulation products are also manufactured in Sweden, Estonia, Lithuania, and Spain in addition to Finland.

We aim to ensure that we operate responsibly at each stage of the value chain and consider the economic, environmental, and social impact of our activities. We invest in the competence of our personnel, and we are always developing new innovations to further improve the effectiveness of our value chain. 

We believe in conducting our business in a sustainable and responsible manner, and we want to be a trustworthy employer, expert, and partner. 


It has always been Finnfoam’s goal to provide cost-effective thermal insulation solutions to its customers. One of the key objectives in the development of our products has been prolonging their life cycle.

Our innovative inventions have led to several patents and successful products, which also enable our growth internationally. We are keenly interested in contributing to the development of better construction practices and the improvement of public health.


Finnfoam is participating in a project, where compostable bioplastic is produced for the first time in the world using byproducts from food and feed production. The project involves Brightplus, VTT, and Nordic Soya. A pilot plant will be constructed in Uusikaupunki in 2021–22. In the future, Finnfoam aims to use the new bioplastic material in the production of thermal insulation for buildings. “The environmental friendliness of bio-based insulations is further increased by the fact that the thermal insulation also functions as a carbon sink, thus reducing the carbon footprint of the building”, says Finnfoam CEO Henri Nieminen.
