EPS insulation products made to last from one generation to the next

Our EPS insulation products are designed for durable construction. The end result is energy-efficient, which means savings on building and heating costs. EPS insulation by Solupak helps you build homes and other facilities that last from one generation to the next.

Insulation experts with experience spanning seven decades

The history of Solupak goes back to the 1950s, when the grandfather of present owners, brothers Pentti Sintonen and Veikko Sintonen, founded a factory for the production of wood wool boards in Tarvasjoki. Second-generation entrepreneur Tapani Sintonen established Solupak in 1985.
The responsibility for leading the family business has now been handed over to the third generation, as Tapani Sintonen passed away after serious illness on 1 January 2013. His work is carried on by Jukka-Pekka Sintonen as CEO and Leena-Maija Mecklin as Chair of the Board.

Energy-efficient and environmentally friendly EPS insulation

EPS insulation products are mainly used as thermal insulation in buildings, but they are also suitable as insulation for mechanical installations or light-weight solutions in road building and earthworks in yard areas. EPS insulation is also used in packaging, dock structures and elsewhere.
The best material-efficiency in buildings is ensured by the longest possible service life and minimal need for repairs. Using EPS insulation in construction is energy-efficient and therefore environmentally friendly, as EPS retains excellent thermal insulation characteristics throughout its long service life of decades in length.
Due to its light weight, the insulation is easy to handle and install; it does not decay or grow mould and is available in various shapes and thicknesses. EPS insulation products are also produced using the not readily igniting S-type, which does not support combustion.

For a new era in construction

Solupak Carbon is an EPS insulation product for a new era in construction. Its thermal insulation performance is up to 20 per cent higher than that of standard EPS insulation.The Carbon product line is specially designed for low-energy and passive building, as well as for structures with strict limitations on the thickness of insulation.
Solupak Carbon is available for floor, wall and roof insulation. You will recognise Solupak Carbon insulation products by their distinctive grey colour.
