Cement Block with Enhanced Performance

The Ashkalit 268 white block features a unique chemical structure with a higher cement content, delivering superior thermal and acoustic insulation, low capillarity, high strength, and reduced weight. Ashkalit 268 offers a wide range of block types and sizes, providing maximum flexibility for construction needs—from envelope walls and interior partitions to channel blocks, strut blocks, lintel beams, and insulation panels.

Maximum Thermal Insulation for Energy Savings

The advanced Ashkalit 268 block offers exceptional thermal insulation, exceeding Israeli Standard requirements across all regions. Its insulation performance is three times higher than a standard block and twelve times higher than concrete. Buildings constructed with the white block maintain optimal indoor temperatures year-round, reducing energy use for heating and cooling, cutting electricity costs, and significantly lowering toxic gas emissions.

A Unique Structure for Superior Acoustic Insulation

The white block’s unique porous structure, low density, and material composition provide excellent acoustic resistance, minimizing noise transfer between spaces while reducing structural load. This enables the creation of complete wall systems ideal for acoustic separation between apartments, offices, hotel rooms, and hospital spaces. The system exceeds Israeli Standard requirements, offering improved acoustic comfort and a better quality of life for residents.

The Highest Fire Resistance in Building Materials

The Ashkalit block is classified as non-combustible by the Standards Institute, achieving the highest fire rating of V1.4.4 across parameters such as toxic emissions, combustibility, flammability, and smoke density. Incorporating Ashkalit blocks into insulation walls protects the building frame during fires and prevents heat transfer to the reinforcement and concrete. These properties also make the block ideal for use in smoke shafts, fire partitions, and intake and expulsion shafts. 

White Block for Green Building

The Ashkalit 268 cement block holds a high energy rating and a Green Label from the Standards Institute of Israel. Made entirely from natural raw materials, it emits significantly lower radiation than the standard allows. Its high air content makes it lightweight, reducing the amount of raw material used per block. Its monolithic structure also allows easy cutting with minimal waste on-site. Even if a structure is demolished, block residues naturally decompose without harming the environment.

Low Capillarity Level

The Ashkalit block, made from cured cellular concrete, is highly resistant to water penetration. Its improved chemical structure and unique cement formula result in a capillarity level significantly lower than that of standard concrete blocks. The block’s porous structure also allows it to release humidity easily, helping to prevent condensation, mold, fungi, and damp patches more effectively than any other building material.

A Particularly Strong and Resilient Block

Despite its lightweight, airy texture, the Ashkalit white block is one of the strongest and most resilient building materials. Tensile and compressive strength tests show that it meets—and even exceeds—standard requirements. Its low weight reduces the load on the building frame, while its uniform, solid structure enhances resistance to earthquake shocks, unlike hollow blocks that are more prone to cracking.
