Features & Benefits

Cost-Saving

Featherlite blocks are X9 the size of clay bricks, reducing the need for mortar joints by over 66%.

Energy Efficient

Featherlite blocks help with Thermal Insulation by maintaining distinct internal and external room temperatures, thereby saving energy costs. 

Fire-Resistant

Featherlite blocks are fire-resistant for about 2 to 6 hours, depending on the thickness of the wall. 

Pest Resistant

Featherlite blocks are made of inorganic materials, which keep termites away and prevent wall damage.

Water Saver

Featherlite blocks do not need watering; only the conventional mortar joints need to be cured with water, thereby reducing water consumption.

Minimum Storage

Featherlite Buildcon maintains a year-round supply; hence, buyers benefit from minimum storage requirements.

Time Saving

Featherlite blocks’ lightweight property makes them easy to handle compared to conventional bricks and decreases lead time and installation time. 

Sound Insulation

Featherlite blocks have a commendable Sound Transmission Class (STC), which is appropriate for sound insulation in building walls
