Delta block is a super lightweight masonry block that enhances sustainability & durability; it is also fire resistant, mold resistant, sound-proofed, and it minimizes Heating, Cooling, and Air Conditioning (HVAC), leading to an energy efficient comfortable indoor climate. Delta Block autoclaved aerated concrete (AAC) is the brand of the century; it is considered to be one of the strongest brands in the building materials market. It has a long term guarantee for the best thermal insulation and solid quality. Delta Block breathes, due its unique cellular structure, and therefore creates a healthy environment for the people in the building.
Delta Block is the highest thermal insulating building material (interior/exterior walls). The Ideal heat insulation is obtained by trapping a large quantity of air in little pores so that it can no longer circulate. Delta Block’s insulating properties are the same in every direction of the block, which aids in reducing the thermal bridges significantly.
Comfort In Winter & Summer:
Due to its excellent insulation capability and high thermal inertia, Delta Block guarantees a pleasant room temperature inside the building during any heat waves coming by. Conversely, in winter or at colder times, Delta Block preserves the heat. In other words: warm in winter and cool in summer.
Optimum Fire Resistance:
The raw material adopted and the Delta Block building unit itself is absolutely fire resistant. Experimental results that have been conducted shows that 10 cm thick walls made of Delta Block can withstand fire for at least 4 hours.
Delta Block provides the highest security against fire and meets the most stringent fire safety requirements. It is classified as a non- combustible building material and is fire resistant up to 1200°C, therefore it is a firewall that prevents fire from spreading within a building, thereby protecting lives and economic assets. In addition to that, Delta Block does not exert any smoke or toxic gases, which often endanger human lives more than the fire itself; hence, is a superior fire protection wall building material to any other material in the industry.
Lightweight Construction Material:
Delta Block’s production process allows it to combine its lightweight i.e. low density with high strength. Taking this data into account a lighter and thus more economical load bearing structure can be designed.
The dry density of delta block ranges between (500-550kg/m3), which is 1/3 of clay bricks, and 1/4 of concrete blocks. Being lightweight, Delta Block (AAC) radically reduces the dead-weight of any building, which results in reducing the amount of steel used (up to 15% of structural cost savings), which eventually reduces the cost of materials used to construct any building.
High Construction Speed:
Delta Block is made of inorganic material and its durability is quite similar to concrete. Delta Block AAC can be sawed, drilled just like wood, and thus is a very durable construction material. It facilitates easier fitting of plumbing, electricity and also wall fittings. Plena- Egypt offers for free (subject to policy) all equipment needed to facilitate the construction process when using Delta Block on site; to ensure efficient productivity and economic usage of our products. The average productivity per day of using Delta Block AAC is 1.5 more productive than the average productivity per day of using an ordinary block (e.g. clay or cement bricks) during the construction process.

This ultimately results in a reduced construction time which delivers cost savings particularly in high-volume projects.
Ecological and durable:
Delta Block has been known well-known as an ecological material since it enhances sustainability. It is manufactured by progressive technology using the most modern quality control equipment, and this guarantees high quality products and reliable technical characteristics. In addition to all this information, Delta block is composed of natural raw materials: cement, lime, sand, and water. Our “Go Green!” policy ensures that Delta Block is the most environmentally- friendly building unit, and by using natural products to manufacture our block, it is guaranteed to result in a greener outcome.
The material and product properties make this block suitable for both new-build projects and for renovation works. The light weight and the ease of construction especially play an important role in the field of renovation. Blocks remain well within the working conditions requirement that blocks must not be heavier than 18 kilograms. This means that the block is, primarily, a labor-friendly product.
Sound Reduction and Acoustic Performance:
Since the Delta Block (AAC) has a stomatal structure, the internal structure of aerated concrete is like bread- it is evenly distributed and has a large number of closed pores, therefore it demonstrates efficient performance in acoustics and noise insulation. Sound Insulation of different products, with different finishing touches or thicknesses can range from 40- 60db. Also, AAC wall has an excellent sound transmission class (STC) rating, which is 48, and this ensures efficient sound proofing in any building. The use of Delta Block not only isolates outdoor noise interference but also assures a comfortable sound environment indoors.
