1 Quality Management

Maintaining high quality products is the first commitment of the company towards its valued customers. Quality Assurance Department was established to insure the conformity of the products to the relevant technical local and international standards. The highly equipped in-house laboratory is utilized to perform most of raw material and product testing, additionally SRWF products are frequently tested by local and international third party independent laboratories for certification and approval purposes. This enabled the factory to obtain ISO 9001 Quality System Certificate since 1998, in addition to European Conformity Mark (CE) and Dubai Central Laboratory (DCL) Certificates. Additionally, products are classified and certified as A1 by Warrington as per Euro fire classification (EN13501).

SRWF products are recently certified by UL as Zero flame spread and Zero smoke develop indexes according to UL 723 (equivalent to ASTM E84, surface burning characteristic). Also Saudi Rockwool Factory and Products (Panel & Mattress) are approved by Saudi Civil Defence as fire proof products.

2 About Rockwool Advantages of Rockwool: Rockwool is considered as a high performance material in the thermal, acoustic insulation and fire resistance applications.

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 People close to volcanic reduce the heat transfer through the walls and the roofs. areas, have known Today with the raise of energy and living costs, the most Rockwool since a long practical and cost effective way to make a house more time. They observed energy efficient is by keeping it cool in summer and warm fiber being formed by air in winter and save money by lowering your electricity bills hitting the lava. by insulating your homes.

A Danish scientist brought the principles of using rock fibers Based on the above, rules and regulation were adopted in in the thermal insulation, and established the first Rockwool making thermal insulation in private or public buildings as plant in 1937, rockwool production spread to the rest of the mandatory. The thermal resistance of walls and ceiling are world since then. specified to suit the geographical region of most countries.

Rockwool fibers are produced from natural volcanic rocks, Professional studies proved that the thermal insulation cost which are melted in special furnaces at a temperature of more in a building will not exceed 3-5% of the building cost. This than 1500˚C. amount however, will be paid back in 4-5 years as a result of the saving in the electricity bill.

3 Acoustic insulation Non-combustible material

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 Saudi Rockwool products are made from rock thus construction systems (Gypsum board, Cement boards, non-combustible, melting point above 1100°C. Concrete blocks, etc. please refer to page no. 14 to 16 for Rockwool does not ignite and does not contribute to details.) the development or spread of fire it doesn’t emit toxic Due to its open cell structure, fumes. Saudi Rockwool has superior sound According to marine standard test (IMO Resolution A.4722 absorption properties. (NRC>0.95 for XII), rockwool is approved as a non-combustible material 2” thick). Saudi Rockwool used to and withstands high temperatures. Saudi Rockwool is decrease the reverberation time Sound Level dB approved as Non-combustible according to ASTM E136 and of rooms (Class rooms / Studios / Theatre / EN1182. It is also classified as Non-combustible material Conference halls / Airport terminals) providing comfort and (A1) according to the European standard CSNEN 13501-1 sound intelligibility to both sound source & receiver. and approved as Zero flame spread & Zero smoke develop Sound Absorption of Saudi Rockwool (NRC): index according to UL standard 723.

The presence of sodium and silicate irons in the Rockwool Water and moisture have negative effect on the thermal insulation has found to be inhabit to the external stress conductivity (K-Value) and efficiency of the insulation. corrosion cracking caused by chloride & fluoride ions. Rockwool fibers are treated with special additives, to improve their resistance to water & moisture absorption. The concentration of these ions was measured according to the test method of ASTM C871; it was found that the Additionally it is completely resistant to rot, mildew, leachable ions are within the acceptable safe zone as per mold and bacterial growth, contributing to a safer indoor ASTM C795. environment.

Thus Saudi Rockwool do not cause, Initiate or promote These properties are tested according to American any kind of corrosion. standards of ASTM C1104, ASTM C209 and British standards of BS EN 2972, EN1609 & EN 12087.

Compatible with Building materials No health hazard

Saudi Rockwool is mainly consists of inorganic compounds Saudi Rockwool material is tested and approved to be free such as silica, aluminum, calcium & ferrous, which are from Asbestos and classified as non-carcinogenic material. found in most of the construction materials (like cement, Rockwool is classified by the World Health Organisation’s gypsum, blocks) thus it is more compatible with the building International Agency for Research (IARC) Group 3A Not materials.. classifiable as to its carcinogenicity to humans”.

Light weight, easy to handle and install Environment friendly

Saudi Rockwool is produced with various densities ranging No harmful industrial pollutants are produced from from 30 up to 200kg/m3, according to the required Rockwool production process. The wastes from fabrication application, therefore the maximum density of Rockwool is processes are recycled; the exhaust gases from production equivalent to 10-15% of construction materials densities, process are treated and reduced to the international and consequently Rockwool will cause no significant load to allowable limits. the building structure. Rockwool is highly flexible material and easy to install with required shape by using a simple cutter or carpenter saw.

16 Thermo-Physical Properties of Building Materials

* Thermal conductivity (k-value) R= X/K, X- Material thickness (mm) & K- Thermal conductivity (w/mK) The k-value of a material is defined as the quantity of heat transmitted under steady-state conditions Total Thermal Resistance: (RT) through unit area of the material of unit thickness in unit time when unit temperature difference exists The thermal resistance of a material or construction is between its opposite surfaces. It is expressed in the reciprocal of its thermal conductance. It refers to the W/m K. thermal resistance of any section or assembly of building components and is particularly useful in computing the The thermal resistance is a heat property and measurement overall transfer of heat across the building section. It is of a temperature difference by which an object or material expressed as m2.k/W and is given by: resist a flow (m2 K/W). RT = R1 + R2 + R3 … RN

17 Resistance from Air Films and Air Spaces Thermal Transmittance (U-value):

Air films are layers of air that are assumed to be static The thermal transmittance or U-value of a construction is on each side of a building envelope, and air spaces are defined as the quantity of heat that flows through a unit volumes of air within building constructions they are both area of a building section under steady-state conditions in interesting thermal components they have potentially useful unit time per unit temperature difference of the air on either thermal properties. They can contribute substantially to the side of the section. It is expressed in W/m2.k and is given by: insulating capabilities of construction assemblies - Thermal Transmittance (U-Value) = 1/RT
