INTRODUCTION

ABOUT PAROC

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 iin 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 tto 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 aat 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.

PROPERTIES

FIRE SAFETY

Paroc stone wool products are mmade 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

without restrictions.

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 iinsulation 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

facilities.

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.

SOUND REDUCTION

Stone wool is an ideal material for sound absorption and noise

abatement.

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 uused in floor structures

for the reduction of the impact noise as well as in the vertical structures

for the reduction of the air bound noise. The impact noise insulation is

based on the principle of creating a floating floor by applying insulation

between the supporting floor structure and the surface structure. It is

important for the impact noise insulation to have the right dynamic

stiffness to achieve the best noise reduction. In vertical structures Paroc

bats and slabs are used as cavity filling to improve the sound reduction of

the 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 to

provide a good fit.

Semi rigid slabs are intended for applications where the requirement

for the load bearing capacity is in the range of 10 kPa. Rigid insulation

slabs and boards are designed to be used in the most demanding applications

where the load bearing capacity reaches 25 – 70 kPa.

Paroc stone wool keeps its dimensions since changes in temperature or

humidity do not cause expansion or shrinkage. Problems from opening gaps in

the joints causing heat loss do not appear.

APPLICATIONS

INDUSTRY

Industrial applications are one of tthe most important areas for the use of

the Paroc technical insulation products. Applications vary from process

piping and tank wrapping to power plant boilers and smoke flues.

Good insulation is a vital component in safeguarding the energy efficiency

of an industrial process. It is not only the question of lowering the

energy expenditure but also to contribute to the environmental protection

by 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 homes

and large developments of apartment buildings. Low energy bill is the wish

for everyone to keep the rents and housing costs at a reasonable level. But

at the same time comfortable and healthy indoor climate is appreciated. By

the use of good insulation both of these wishes can be fulfilled.

MARINE

The requirements of insulating materials for the Marine use are strict. It

is extremely important to use fire safe products for the onboard

applications such as big cruisers, where thousands of passengers are on the

open sea. All products for the Marine applications must be tested and

accepted to be non-combustible and fire proof for their use.

Because of the excellent properties of the Paroc Marine product for

this sector, they are widely used

in all type of vessels.

PRODUCT GROUPS

ROOFS

Roof is the fifth facade of the building. The slope, the supporting

structural system and the finishing material may vary upon the architecture

of the building, but the roofs are always insulated. Paroc offers proven

insulation systems for various types of roof starting from simple loft

insulation to flat roofs in size of a football field.

Paroc has a wide expertise in providing systems that will function

trouble free in the most demanding climatic conditions over tthe years.

Product selection includes rigid slabs and boards for single and double

layer systems, which may be delivered also cut to fall to increase the

slope angle in the retrofit applications.

WALLS

From the insulation point the facades can be differentiated by whether

they are constructed with an air gap for ventilation or compact without a

cavity.

Sandwich types of facades are examples of closed structures. The

traditional concrete sandwich panel is still widely being used although it

has been partly phased out by new systems.

The new systems are typically constructed by applying rendering on top

of the insulation on the building site. These systems can further be

differentiated by the method fixing the insulation and of applying the

rendering. Typical examples of the ventilated facades are the ccurtain wall

type of structures in which glass, metal, natural stone or some sheeting

material is used as exterior lining. Below the exterior lining there is

always an air space on the cold side of the insulation.

HVAC

The heating ventilation and air conditioning systems in the buildings

are in most cases insulated. Insulation is needed either to keep the

circulating hot water or air warm or to keep the cooling water cold and to

avoid condensation.

In the HVAC applications fire safety is an important criterion when

choosing the insulation. Paroc offers a wide selection of stone wool and

foamed polyethylene bases insulation products for the mechanical systems in

buildings. Product selection includes pipe sections, wired mats, lamella

mats and slabs.

ACOUSTIC

The sound absorption coefficient for stone wwool is close to one, which

means that it is an ideal material for acoustic treatment of rooms. Paroc

acoustic slabs are made from stone wool and faced with a variety of

decorative linings to suit different architectural designs. Slabs are

usually fastened either by gluing to the ceiling or by hanging in a

suspended ceiling grid system which may either be concealed or exposed.

The main applications include decorative ceilings for schools, offices

and public buildings, hygienic ceilings for hospitals, laboratories and

kitchens, and sound absorbing cceilings for industrial facilities.

PANEL SYSTEM

Paroc Panel system is a rational building system used for instance in

industrial buildings, sport facilities, and commercial buildings – wherever

there 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, tightness

and thermal insulation are among the unique performance characteristics

when 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 a

rational product to match the demands of modern building: appearance, short

construction time, excellent fire safety, energy saving, a high degree of

flexibility, and good overall economy.

-7-

PROCESS

Industrial processes are consumers of large quantities of energy. To

function optimally and to be efficient in the use the process equipment

need to be well insulated. In many cases insulation is also necessary for

the personal safety of the workers against the hot surfaces that they might

come in contact with. In processes that operate below the ambient

temperature insulation is needed against condensation.

For normal process applications the maximum service temperature of the

Paroc technical insulation products is 750 C but Paroc offers also a

special product for hhigh temperature applications, in which the maximum

service temperature is 900 C.

MARINE

The most important reason to insulate onboard is to save lives in case

of fire. It is also vital to arrange good working conditions for the staff

and an enjoyable environment to all passengers provided by the thermal and

acoustic insulating products. Paroc Marine insulation offers the most

sophisticated products and solutions to establish the passive fire

protection and the comfort insulation easy and effectively for the ships.
