Modcrete  AAC Blox PLUS


Thermal Insulation

While the thermal conductivity of normal AAC Block is 0.24 W/m K, ModCrete AAC PLUS a very low thermal conductivity of 0.07 W/m K, which provide approximately 3 times better heat insulation than AAC blocks.

Light Weight

AAC blocks have a density range of 451 kg/cum to 750 kg/cum. This results in total cost savings as well as a faster construction period.

High Strength

High pressure steam curing autoclaving process gives AAC unmatched strength to weight ratio, which far exceeds the Indian Building code requirements

Sound Proof

AAC walls have an excellent sound transmission class (STC) rating of 44. Which results to virtually soundproof interiors, which in turn provides Excellent Acoustic Performance.

Cost Effective

Being lightweight, AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 20%) and cement (up to 25%) structural cost saving. Lighter product reduces transport costs as well being 15 times the size of a clay brick, AAC wall construction involves 1/15 of joints, thus an overall mortar saving up to 66%

Fire Resistant

Best in class fire rating of 4 hours. The melting point of AAC is over 1600 celcius. more than twice the typical temperature in a building fire of 650 celcius.

Accurate Dimension

Its automatic manufacturing process gives AAC an exceptional dimensional accuracy & smooth surface, eliminating need of three-coat plaster walls and allowing for a final 6mm skim coat (putty/pop). Our AAC provides greater Design Versatility & Flexibility.

Superior Durability

AAC blocks are highly durable and can bear adverse weather conditions. Furthermore, they are earthquake resistant. Being ultra-light weight helps AAC be long lasting. Regions of high seismic activity like Japan exclusively use AAC. As it has proven to withstand wind loads of category 5 tropical storms.


AAC blocks can be sawed, drilled, just like wood and hence they prove to be one of the most easy to use construction materials’. It facilitates easier fitting of plumbing, electrical and also wall


Eco Friendly

AAC is 100% Green Building Material & is a walling material of choice in LEED certified buildings. AAC is most energy & resource efficient in the sense that it uses least amount of energy & material per m3 of product. Unlike brick manufacturing process which uses previous top-layer agricultural soil, AAC uses FlyAsh (65% of its weight).

Termite & Insect Resistant

Solid wall construction and finishes which bond to the wall have no cavities for insects, termites or rodents to dwell in. This also eliminates entry points. Termites and ants do not eat or nest in AAC. Cannot be penetrated by termites or insects. Reduces need for pest control. Offers maximum protection against damage.

Faster Construction

AAC Blocks helps reduce the construction time by upto 20%. Different sizes of blocks help reduce the number of joints in wall masonry. Easy to install. It sets and hardens very quickly. Lighter blocks make construction easier and faster

ModCrete AAC Blox PLUS


ModCrete AAC Blox PLUS is a very high heat barrier. It provides almost 10 times better than red bricks and 3 times better than ModCrete AAC Blox in thermal insulation. While the thermal conductivity of normal AAC Block is 0.24 W/m K, ModCrete AAC PLUS a very low thermal conductivity of 0.07 W/m K, which provide approximately 3 times better heat insulation than AAC blocks.
