Bricks have been used as a primary building material for centuries. You may have noticed that some bricks have holes in them while others are solid. Bricks with holes are known as core hole bricks or frog bricks. These bricks have a hollow space in the center that is created during the manufacturing process. The hollow space is known as a core hole or recess and is referred to as a frog. Here are some interesting facts about core hole bricks or frog bricks:
The purpose of creating core holes in bricks is to reduce the weight of the bricks and create good thermal insulation, which makes them ideal for building walls.
The holes in core hole bricks also make them more adaptable to different types of masonry techniques. They allow bond beams, reinforcing steel, lintels, and electrical conduit to be easily placed in the wall during construction.
Different types of core hole bricks can vary in the number, size, and placement of the holes. This variety in shape and size gives builders more flexibility in creating designs for commercial and residential structures.
Although core hole bricks are more commonly used in construction, solid bricks also offer numerous benefits. They are strong, durable, and provide superior sound reduction and fire-resistant properties.
In summary, core hole bricks or frog bricks are designed for keying in and reducing weight, creating good thermal insulation, and have fantastic adaptability to different masonry techniques, making them the perfect choice for constructing walls.
