U-Blocks & O-Blocks
Magicrete's U and O-shaped AAC blocks elevate construction versatility, harnessing the proven benefits of AAC technology while introducing new dimensions of functionality. These blocks facilitate reinforced masonry, eliminating the need for beams and columns in G+1 houses, thus streamlining construction and enhancing structural integrity.
With reinforced masonry capabilities, these blocks are ideal for applications requiring heightened security. Engineered to maximize thermal and acoustic insulation, resist corrosion and earthquakes, and comply with Indian Building Code standards, Magicrete U Blocks & O Blocks stand as the epitome of innovation in construction materials.
Features

Earthquake Resistant
Magicrete U-Blocks and O-Blocks are up to 3 times lighter than regular bricks. They reduce the overall dead weight of a building allowing excellent resistance to earthquakes. Ideal for tall multi-storied residential or commercial buildings, particularly in earthquake prone areas, these blocks provide enhanced structural integrity and durability.

Sound Insulation
Magicrete U-Blocks and O-Blocks keep out the noise and let you experience unmatched calm. The air pockets in them absorb external noise providing best in class sound insulation that meet Sound Transmission Class (STC) 44 standards.

Moisture Resistant
Say goodbye to leakage related problems for good. Magicrete U-Blocks and O-Blocks are all-weather AAC blocks. They have a very porous structure which prevents condensation or dampness. The use of silicone based additives adds to the water resistant properties of our blocks.

Thermally Insulated
With Magicrete, your air conditioner will not need to work too hard to keep you cool. The result: lower power bills. Magicrete U-Blocks and O-Blocks have the highest thermal rating in the industry- R30. It helps maintain the temperature of your room in summer as well as winter due to its exceptional thermal insulation properties.

High Strength
Magicrete U-Blocks and O-blocks undergo a high pressure steam curing autoclaving process giving them a high strength to weight ratio. Multiple lab tests have proved that these blocks are stronger than even M 150 concrete and exceed Indian Building Code requirements by a large margin.

Fire Resistant
Magicrete U-Blocks and O-blocks keep your loved ones safe from the perils of fire. The cellular structure of these blocks can withstand up to 4 hours of direct exposure to fire. At 1600 degree Celsius, its melting point is more than two times the typical temperature in a building fire which is 650 degree Celcius.
