Question 1

How much do aerated blocks cost in the UK?

Accepted Answer

The price of aerated concrete bricks in the UK generally ranges from £1.00 to £10 per unit, influenced by factors such as size, grade, and supplier. Standard-sized blocks, such as 440mm or 620mm lengths, are usually priced at the lower end of this range, offering affordability for large-scale building projects. Higher-grade blocks with enhanced properties, such as increased strength or superior thermal insulation, tend to cost more.

Additionally, blocks with specialised features—like fire resistance or insulation inserts—may push prices toward the upper limit. Purchasing in larger quantities often results in discounted rates, making bulk orders more economical for contractors and developers. Carefully comparing suppliers and considering long-term durability can help you find the best value, ensuring your project remains within budget without compromising on quality.

Question 2

What considerations need to be taken into account when selecting aerated blocks?

Accepted Answer

When choosing aerated concrete blocks, key factors include compressive strength, with higher grades like 7.3N for load-bearing applications and lower grades such as 3.6N for internal partitions. Consider the thermal insulation properties to ensure energy efficiency and indoor comfort, choosing the appropriate thickness and grade. The size and dimensions should match your project plans, with common sizes being 440mm or 620mm in length and varying thicknesses from 75mm to 215mm. Also, evaluate the fire resistance, as many aerated bricks offer up to 4 hours of fire protection for safety compliance. Finally, weigh the cost-effectiveness, considering durability and ease of installation to achieve long-term savings.
