Finnfoam is a family-run business whose roots are embedded into the frozen Finnish soil
Best solutions for all your insulation needs
Over the course of its nearly forty-year-long history, Finnfoam has become one of the leading manufacturers of plastic-based thermal insulation solutions. The roots of our thermal insulation competence are embedded into the frozen Finnish soil. Today, the group is known for quality, product development, and reliability.
Our strengths in designing and manufacturing thermal insulation products are distilled into robust experience and novel thinking. We are able to offer our customers patented products and solutions whose insulation capacity, reliability, and ease of installation are at a level of their own.
We continue to increase our production capacity and today we produce insulation products in Sweden, Estonia, Lithuania, and Spain in addition to Finland.

It is our vision to be a safe Finnish trailblazer for ecological construction. Our strategy, mission, and values guide our daily work toward our goal.
We aim to operate responsibly throughout the value chain and to account for the economic, environmental, and social impact of our activities. We invest in the competence of our personnel and continue to develop new innovations to reinforce the functionality of the value chain.
Sustainable and responsible business activities are important to us, and we want to be a reliable employer, expert in the field, and partner.
Durable and functional

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.
