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.
