INTRODUCTION
ABOUT PAROC
We have almost 50 years’ experience of developing, manufacturing anddistributing stone wool products for use by the building industry and otherindustries. We are currently the leading stone wool manufacturer in theBaltic region, with Sweden and Finland as our main markets. Our annualturnover is more than 235 million euro. Paroc has plants in Finland, Sweden, Poland, Lithuania and the UnitedKingdom, 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, especiallyin Finland . About a third of Finland lies within the Arctic Circle. Thelowest 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 theNordic region to advance to its world-class position. As an insulationproducts manufacturer, Paroc has played an important role in this processand intends to continue doing so in the future. The raw material in our products is stone, which we crush, sort andmelt at approximately 1500 0 C. the melted products is then converted tostone wool- a material that is superior in providing good insulation, longdurability and maximum fire protection. A similar manufacturing process can be found in nature. In 1788 ascientific expedition from the US found a wool- like stone material on theslopes of the volcano Kilauea on the island of Hawaii. The Hawaiians calledit “the hair of Pele” – Pele being the goddess of the volcano. They saidthat 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. -2 –PROPERTIES
FIRE SAFETY
Paroc stone wool products are made from stone material, and only smallamount of binder is added in the production process.
Paroc stone wool products are classified non-combustible based on theinternational standard ISO 1182. They can be used in all types of buildingswithout restrictions. The high melting point makes Paroc an ideal material for the use in thefire insulation applications. Partitions are designed to restrict the firepenetration from one fire zone to another. Filling the cavity with Parocbatts can considerably increase the fire resistance of the partitioning.Fire insulation is also necessary to protect the frame structure, whichcarries the loads and prevents the building from collapsing in a fire.Paroc fire insulation slabs are approved for fire protection of loadbearing steel and concrete structures. In acoustic linings and applications where the insulation product isleft open it is necessary to fulfill the requirements for ignitability,spread of flame and smoke generation. Paroc products meet the moststringent requirements of the surface criteria, which allow them to be usedin all parts of the building including the hallways and the technicalfacilities.
RESISTANCE TO WATER AND MOISTURE
Paroc insulation products are intended is used in dry conditions. Stonefiber is non-hygroscopic and the moisture content of the insulation innormal service conditions remains below 0,5 % in weight. During the building and installation process water is often present. Toguarantee the proper functioning of the insulation, Paroc products aretreated with water repellent agent. This allows the products to be used innormal weather conditions with an exposure to rain.
-3- SOUND REDUCTION Stone wool is an ideal material for sound absorption and noiseabatement. 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 structuresfor the reduction of the impact noise as well as in the vertical structuresfor the reduction of the air bound noise. The impact noise insulation isbased on the principle of creating a floating floor by applying insulationbetween the supporting floor structure and the surface structure. It isimportant for the impact noise insulation to have the right dynamicstiffness to achieve the best noise reduction. In vertical structures Parocbats and slabs are used as cavity filling to improve the sound reduction ofthe partitioning.MECHANICAL PERFORMANCE
Paroc building insulation products can group into three categories:flexible mats and bats, semi rigid slabs, and rigid slabs and boards.Flexible bats are used in framed constructions in which it is important toprovide a good fit.
Semi rigid slabs are intended for applications where the requirementfor the load bearing capacity is in the range of 10 kPa. Rigid insulationslabs and boards are designed to be used in the most demanding applicationswhere the load bearing capacity reaches 25 – 70 kPa.
Paroc stone wool keeps its dimensions since changes in temperature orhumidity do not cause expansion or shrinkage. Problems from opening gaps inthe joints causing heat loss do not appear.

APPLICATIONS
INDUSTRY
Industrial applications are one of the most important areas for the use ofthe Paroc technical insulation products. Applications vary from processpiping and tank wrapping to power plant boilers and smoke flues.
Good insulation is a vital component in safeguarding the energy efficiencyof an industrial process. It is not only the question of lowering theenergy expenditure but also to contribute to the environmental protectionby reducing the emissions of a plant.
RESIDENTIAL
Residential building is by volume the largest segment for the use of
insulation. These buildings vary from a single-family house to town homesand large developments of apartment buildings. Low energy bill is the wishfor everyone to keep the rents and housing costs at a reasonable level. Butat the same time comfortable and healthy indoor climate is appreciated. Bythe use of good insulation both of these wishes can be fulfilled.MARINE
The requirements of insulating materials for the Marine use are strict. Itis extremely important to use fire safe products for the onboardapplications such as big cruisers, where thousands of passengers are on theopen sea. All products for the Marine applications must be tested andaccepted to be non-combustible and fire proof for their use. Because of the excellent properties of the Paroc Marine product forthis sector, they are widely used in all type of vessels.

PRODUCT GROUPS
ROOFS Roof is the fifth facade of the building. The slope, the supportingstructural system and the finishing material may vary upon the architectureof the building, but the roofs are always insulated. Paroc offers proveninsulation systems for various types of roof starting from simple loftinsulation to flat roofs in size of a football field. Paroc has a wide expertise in providing systems that will functiontrouble free in the most demanding climatic conditions over the years.Product selection includes rigid slabs and boards for single and doublelayer systems, which may be delivered also cut to fall to increase theslope angle in the retrofit applications. WALLS From the insulation point the facades can be differentiated by whetherthey are constructed with an air gap for ventilation or compact without acavity. Sandwich types of facades are examples of closed structures. Thetraditional concrete sandwich panel is still widely being used although ithas been partly phased out by new systems.
The new systems are typically constructed by applying rendering on topof the insulation on the building site. These systems can further bedifferentiated by the method fixing the insulation and of applying therendering. Typical examples of the ventilated facades are the curtain walltype of structures in which glass, metal, natural stone or some sheetingmaterial is used as exterior lining. Below the exterior lining there isalways an air space on the cold side of the insulation.-6- HVAC The heating ventilation and air conditioning systems in the buildingsare in most cases insulated. Insulation is needed either to keep thecirculating hot water or air warm or to keep the cooling water cold and toavoid condensation. In the HVAC applications fire safety is an important criterion whenchoosing the insulation. Paroc offers a wide selection of stone wool andfoamed polyethylene bases insulation products for the mechanical systems inbuildings. Product selection includes pipe sections, wired mats, lamellamats and slabs.
ACOUSTIC The sound absorption coefficient for stone wool is close to one, whichmeans that it is an ideal material for acoustic treatment of rooms. Parocacoustic slabs are made from stone wool and faced with a variety ofdecorative linings to suit different architectural designs. Slabs areusually fastened either by gluing to the ceiling or by hanging in asuspended ceiling grid system which may either be concealed or exposed. The main applications include decorative ceilings for schools, officesand public buildings, hygienic ceilings for hospitals, laboratories andkitchens, and sound absorbing ceilings for industrial facilities. PANEL SYSTEM Paroc Panel system is a rational building system used for instance inindustrial buildings, sport facilities, and commercial buildings – whereverthere is a commitment to superior performance. Paroc Fire Proof Panels are highly advanced composite panels based on a
core material of structural stone wool. Fire ratings, strength, tightnessand thermal insulation are among the unique performance characteristicswhen employed as external wall cladding, internal walls and ceilings. The system is an economical application within the facade, hygiene,fire and acoustical segment. The idea behind the system was to create arational product to match the demands of modern building: appearance, shortconstruction time, excellent fire safety, energy saving, a high degree offlexibility, and good overall economy.-7-
PROCESS
Industrial processes are consumers of large quantities of energy. Tofunction optimally and to be efficient in the use the process equipmentneed to be well insulated. In many cases insulation is also necessary forthe personal safety of the workers against the hot surfaces that they mightcome in contact with. In processes that operate below the ambienttemperature insulation is needed against condensation.
For normal process applications the maximum service temperature of theParoc technical insulation products is 750 C but Paroc offers also aspecial product for high temperature applications, in which the maximumservice temperature is 900 C. MARINE The most important reason to insulate onboard is to save lives in caseof fire. It is also vital to arrange good working conditions for the staffand an enjoyable environment to all passengers provided by the thermal andacoustic insulating products. Paroc Marine insulation offers the mostsophisticated products and solutions to establish the passive fireprotection and the comfort insulation easy and effectively for the ships.
