Properties & Benefits

The manufacturing process as well as the basic ingredients used provides Siporex its unique properties and benefits not found in other traditional building materials

Dimension Accuracy

The production process guarantees the accurate dimensions of the panels and blocks that comprise the building system. This allows for a straight and plumbed walls resulting in less on-site trimmings and reduces the quantity of mortar and finishing materials required. The dimensional tolerance is ±3mm for thickness & width and ±5mm for length.


SIPOREX products can be sawn, cut, slot, drilled, chased and nailed with ordinary woodworking tools which makes them easier to install than other building materials. This also simplifies the installation of electro-mechanical services and other utilities, which means more cost savings.

Resistant to Fire

SIPOREX is totally inorganic and does not contain any combustible materials, which means it is resistant to fire. A 15 cm thick panel will resist fire for seven life-saving hours. SIPOREX product complies with the Saudi Building Code thermal requirements with a very low U-value of ≤ 0.34 W/m2.K SIPOREX is ideal for firewall application and as protection for structural steel construction.

Accoustic Insulation

SIPOREX meets the appropriate standards for sound insulation in house building, which means quieter and more comfortable interior. In industrial construction, SIPOREX minimizes industrial noise pollution. The sound absorption of untreated SIPOREX surface is better than that of dense concrete.

Quake Resistant

The low mass of Siporex results to reduced total dead load of the building and consequently reducing the applied seismic forces to its structure. Structures built in earthquake zones such as Japan & Mexico have shown good resistance to seismic forces in actual practice.


SIPOREX products do not contain any organic matter subject to deterioration and will not degrade even under severe weather conditions. Structures built several decades ago are still in active use today.


SIPOREX itself is ecologically harmless, since it neither contains gases nor fibers, it is neither dangerous to ground- water nor does it releases any radioactive radiation. No pollutants or toxic by-products are produced in the manufacturing process or even when subjected to fire.


In relation to its dry density, SIPOREX can withstand relatively high compressive stress, which in the aspect of application is very sufficient to take building loads. SIPOREX achieves its full strength during autoclaving process. Minimum compressive strength is about 35 kg/cm2 for nominal dry density of 550 kg/m3.

Pest Resistant

SIPOREX provides airtight interior, does not contain any organic ingredient and makes your home uninviting to pest, insects or rodents.

Speedy Construction

SIPOREX has all the advantages of a precast system, i.e. eliminates shuttering, wet construction, curing, on-site testing & quality control resulting to reduced overall construction time and cost. It also requires minimal supervision and construction staff.

Energy Efficient

SIPOREX ensures pleasantly healthy and comfortable room temperature without the need for additional insulation. Its thermal insulation and heat retention offer a good protection against rapid cooling or heating up too much. This means lower power consumption in environmental management system.


SIPOREX weighs less than a quarter compared to conventional concrete. Due to the lightweight property of SIPOREX, the foundation loads are greatly reduced resulting to big savings in the overall construction cost especially at areas having poor soil bearing capacity. Its lightweight also means significant advantage in transportation cost.
