We have almost 50 years’ experience of developing, manufacturing and
distributing stone wool products for use by the building industry and other
industries. We are currently the leading stone wool manufacturer in the
Baltic region, with Sweden and Finland as our main markets. Our annual
turnover is more than 235 million euro.
Paroc has plants in Finland, Sweden, Poland, Lithuania and the United
Kingdom, plus sales companies in fourteen European countries.
Paroc offices are located in Vanda (head office) and Pargas, Finland,
and in Skövde, Sweden. We employ some 1,700 people.
THE PAROC GROUP
Paroc’s business idea is based on two opposites
The Nordic winters can fairly be described as long and cold, especially
in Finland . About a third of Finland lies within the Arctic Circle. The
lowest temperature recorded in Helsinki, in the southwest of the country,
is –340 C (1987).
The lowest temperature recorded in Finland this century is -50 0 C
(1985 ). These climatic conditions have forced building technology in the
Nordic region to advance to its world-class position. As an insulation
products manufacturer, Paroc has played an important role in this process
and intends to continue doing so in the future.
The raw material in our products is stone, which we crush, sort and
melt at approximately 1500 0 C. the melted products is then converted to
stone wool- a material that is superior in providing good insulation, long
durability and maximum fire protection.
A similar manufacturing process can be found in nature. In 1788 a
scientific expedition from the US found a wool- like stone material on the
slopes of the volcano Kilauea on the island of Hawaii. The Hawaiians called
it “the hair of Pele” – Pele being the goddess of the volcano. They said
that when she became angry, she tore her hair and spread it about herself.
What really happened was that the volcano blew steam through the thin
layers of lava, producing a kind of natural stone wool.
Paroc stone wool products are made from stone material, and only small
amount of binder is added in the production process.
Paroc stone wool products are classified non-combustible based on the
international standard ISO 1182. They can be used in all types of buildings
The high melting point makes Paroc an ideal material for the use in the
fire insulation applications. Partitions are designed to restrict the fire
penetration from one fire zone to another. Filling the cavity with Paroc
batts can considerably increase the fire resistance of the partitioning.
Fire insulation is also necessary to protect the frame structure, which
carries the loads and prevents the building from collapsing in a fire.
Paroc fire insulation slabs are approved for fire protection of load
bearing steel and concrete structures.
In acoustic linings and applications where the insulation product is
left open it is necessary to fulfill the requirements for ignitability,
spread of flame and smoke generation. Paroc products meet the most
stringent requirements of the surface criteria, which allow them to be used
in all parts of the building including the hallways and the technical
RESISTANCE TO WATER AND MOISTURE
Paroc insulation products are intended is used in dry conditions. Stone
fiber is non-hygroscopic and the moisture content of the insulation in
normal service conditions remains below 0,5 % in weight.
During the building and installation process water is often present. To
guarantee the proper functioning of the insulation, Paroc products are
treated with water repellent agent. This allows the products to be used in
normal weather conditions with an exposure to rain.
Stone wool is an ideal material for sound absorption and noise
By using acoustic slabs in the suspended ceilings the room acoustics
can be improved and the desired acoustic climate created.
Paroc sound insulation slabs are intended be used in floor structures
for the reduction of the impact noise as well as in the vertical structures
