About Rockwool

Thermal insulation and energy saving

Power / energy conservation is one of our civilization aspects

for its positive role in conserving the environment and the

national economy. Scientific research and studies proved

that use of thermal insulation in buildings dramatically

reduce the heat transfer through the walls and the roofs.

Today with the raise of energy and living costs, the most

practical and cost effective way to make a house more

energy efficient is by keeping it cool in summer and warm

in winter and save money by lowering your electricity bills

by insulating your homes.

Based on the above, rules and regulation were adopted in

making thermal insulation in private or public buildings as

mandatory. The thermal resistance of walls and ceiling are

specified to suit the geographical region of most countries.

Professional studies proved that the thermal insulation cost

in a building will not exceed 3-5% of the building cost. This

amount however, will be paid back in 4-5 years as a result

of the saving in the electricity bill.

People close to volcanic

areas, have known

Rockwool since a long

time. They observed

fiber being formed by air

hitting the lava.

A Danish scientist brought the principles of using rock fibers

in the thermal insulation, and established the first Rockwool

plant in 1937, rockwool production spread to the rest of the

world since then.

Rockwool fibers are produced from natural volcanic rocks,

which are melted in special furnaces at a temperature of more

than 1500˚C.

The melting rock runs out from the bottoms of the furnace

to the spinning machine, where the fibers are formed. Minor

amounts of binder and water repellant agent are spared to the

fibers. The wool is collected on a conveyor belt in the collection

chamber & directed to the curing oven to polarimized the

binder.

The cured wool is proceeds to the cutting, facing and packing

stages. The waste inevitably created during the production is

re-cycled.

Rockwool is a highly efficient insulation and used in most of

the known application requiring thermal, acoustic and fire

insulation, thanks to its very low thermal conductivity, very

high melting temperature and it`s open cell structure.

Advantages of Rockwool:

Rockwool is considered as a high performance material

in the thermal, acoustic insulation and fire resistance

applications.

Sound Absorption of Saudi Rockwool (NRC):

Sound Level dB

Acoustic insulation

The Unique structure of the Rockwool makes it an ideal

product as a sound absorber or acoustic insulation, with

high sound absorption coefficient over a wide frequency

range. The acoustical insulation can be made by installing

Saudi Rockwool in wall partitions which provide significant

improvement in their Sound Transmission Class (STC).

High STC can be achieve by using Rockwool with different

construction systems (Gypsum board, Cement boards,

Concrete blocks, etc. please refer to page no. 14 to 16 for

details.)

Due to its open cell structure,

Saudi Rockwool has superior sound

absorption properties. (NRC>0.95 for

2” thick). Saudi Rockwool used to

decrease the reverberation time

of rooms (Class rooms / Studios / Theatre /

Conference halls / Airport terminals) providing comfort and

sound intelligibility to both sound source & receiver.

Saudi Rockwool is very durable and does not lose it’s

insulation properties over time. When properly installed it

maintains it’s dimensions even under changing conditions

of temperature and humidity. Rockwool is inorganic and

chemically inert, thus it sustains its characteristics over time.

Sustainable Insullation

Saudi Rockwool products are made from rock thus

non-combustible, melting point above 1100°C.

Rockwool does not ignite and does not contribute to

the development or spread of fire it doesn’t emit toxic

fumes.

According to marine standard test (IMO Resolution A.4722

XII), rockwool is approved as a non-combustible material

and withstands high temperatures. Saudi Rockwool is

approved as Non-combustible according to ASTM E136 and

EN1182. It is also classified as Non-combustible material

(A1) according to the European standard CSNEN 13501-1

and approved as Zero flame spread & Zero smoke develop

index according to UL standard 723.

Non-combustible material

Saudi Rockwool is mainly consists of inorganic compounds

such as silica, aluminum, calcium & ferrous, which are

found in most of the construction materials (like cement,

gypsum, blocks) thus it is more compatible with the building

materials..

Compatible with Building materials

No harmful industrial pollutants are produced from

Rockwool production process. The wastes from fabrication

processes are recycled; the exhaust gases from production

process are treated and reduced to the international

allowable limits.

Environment friendly

Saudi Rockwool material is tested and approved to be free

from Asbestos and classified as non-carcinogenic material.

Rockwool is classified by the World Health Organisation’s

International Agency for Research (IARC) Group 3A Not

classifiable as to its carcinogenicity to humans”.

No health hazard

Light weight, easy to handle and install

Saudi Rockwool is produced with various densities ranging

from 30 up to 200kg/m3, according to the required

application, therefore the maximum density of Rockwool is

equivalent to 10-15% of construction materials densities,

and consequently Rockwool will cause no significant load to

the building structure. Rockwool is highly flexible material

and easy to install with required shape by using a simple

cutter or carpenter saw.

Water and moisture have negative effect on the thermal

conductivity (K-Value) and efficiency of the insulation.

Rockwool fibers are treated with special additives, to

improve their resistance to water & moisture absorption.

Additionally it is completely resistant to rot, mildew,

mold and bacterial growth, contributing to a safer indoor

environment.

These properties are tested according to American

standards of ASTM C1104, ASTM C209 and British

standards of BS EN 2972, EN1609 & EN 12087.

Doesn’t absorb moisture or water

The presence of sodium and silicate irons in the Rockwool

insulation has found to be inhabit to the external stress

corrosion cracking caused by chloride & fluoride ions.

The concentration of these ions was measured according

to the test method of ASTM C871; it was found that the

leachable ions are within the acceptable safe zone as per

ASTM C795.

Thus Saudi Rockwool do not cause, Initiate or promote

any kind of corrosion.

R= X/K, X- Material thickness (mm) & K- Thermal conductivity

(w/mK)

total thermal Resistance: (Rt)

The thermal resistance of a material or construction is

the reciprocal of its thermal conductance. It refers to the

thermal resistance of any section or assembly of building

components and is particularly useful in computing the

overall transfer of heat across the building section. It is

expressed as m2.k/W and is given by:

Rt = R1 + R2 + R3 … RN

* thermal conductivity (k-value)

The k-value of a material is defined as the quantity

of heat transmitted under steady-state conditions

through unit area of the material of unit thickness

in unit time when unit temperature difference exists

between its opposite surfaces. It is expressed in

W/m K.

The thermal resistance is a heat property and measurement

of a temperature difference by which an object or material

resist a flow (m2 K/W).

Resistance from Air Films and Air Spaces

Air films are layers of air that are assumed to be static

on each side of a building envelope, and air spaces are

volumes of air within building constructions they are both

interesting thermal components they have potentially useful

thermal properties. They can contribute substantially to the

insulating capabilities of construction assemblies -

Thermal Transmittance (U-value):

The thermal transmittance or U-value of a construction is

defined as the quantity of heat that flows through a unit

area of a building section under steady-state conditions in

unit time per unit temperature difference of the air on either

side of the section. It is expressed in W/m2.k and is given by:

Thermal Transmittance (U-Value) = 1/RT
