100mm 7n Medium Density Blocks

100mm Breeze Blocks 7n (Per M2)

The blocks measure 440x215x100mm and are sold per m2 (10 blocks)

7N Medium Dense Blocks (actually 7.3N/mm2) are a type of concrete block that is made with a lightweight aggregate, such as expanded clay or perlite. This gives the blocks a density of around 1350-1400 kg/m3, which is slightly lower than that of solid concrete blocks, but still high enough for them to be used in load-bearing applications.

Medium Density Blocks, also known as Breeze Blocks, Cinder Blocks or Clinker Blocks have a number of advantages over other types of concrete blocks. They are lighter than Solid Concrete Blocks, making them easier to handle and transport. They also have better thermal insulation properties, which can help to reduce heat loss in buildings. Additionally, 100mm Medium Density Blocks are less likely to crack than solid concrete blocks, making them a more durable option.

Breeze Blocks are commonly used in a variety of applications, including:

• Internal and external walls
• Foundations
• Piers
• Partition walls
• Sheds
• Garages
• Infil between Concrete Floor Beams

When choosing Medium Density Concrete Blocks, it is important to consider the load-bearing requirements of the application. Blocks with a higher compressive strength (N/mm2) will be able to support more weight. It is also important to choose blocks that are compatible with the type of mortar that will be used.

Overall, blocks that are 7N medium duty are a versatile and durable option for a variety of building applications. They offer a good balance of strength, weight, and thermal insulation properties.

Here are some additional details about 7N Medium Density Breeze Blocks:

• They are typically made in 2 sizes - 100mm & 140mm thick.
• They can be used with a variety of finishes, including plasterboard (with correct adhesive), plaster, render, and brick veneer.
• They are resistant to fire and pests.
• They are relatively easy to cut and work with.
• Easy to fix in to.

Breeze Blocks technical details:
