7n Celcon Blocks 100mm - per M2 (10 blocks)

Celcon Blocks Hi-Strength Grades are used principally where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings.

Available in compressive strengths of 7.3N/mm2 they are available in thicknesses from 100mm to 215mm.

Advantages of Celcon Hi Seven Blocks:


At 10kg, these blocks are slightly heavier than the 3.6n Celcon but are much lighter than traditional breeze and concrete blocks. This makes them easier to handle and transport. This can save time and money on construction projects.

High thermal insulation:

Aerated blocks' manufacturing process inherently imparts exceptional thermal insulation, enabling energy savings, a crucial factor for both constructing new buildings and revamping existing structures.

Fire resistance:

Celcon 7N blocks are fire resistant, making them a safe choice for construction projects. They are classified as Class A4, which means that they can withstand a fire for up to four hours.

Less harmful to the environment:

Manufactured using pulverised fly ash (PFA) which is an industrial by-product which is therefore less harmful than traditional blocks.


Where can Celcon 7N Blocks be used?

High strength grade blocks are BBA certified and available in thicknesses from 75mm up to 215mm. This means they have many uses including:

• Foundations
• Internal and external leaf of cavity walls
• Solid walls
• Separating walls
• Partitions
• Multi storey buildings

The blocks on offer here measure 440x215x100mm and are sold per m2 (10 blocks).
