Thermalite Aircrete 7.3N Shield Block (High Strength)

The Thermalite Aircrete 7.3N Shield Block is a high-strength aircrete masonry block developed for above-ground walling where added structural capacity is required. It is manufactured from autoclaved aerated concrete, giving it a combination of strength, reduced weight, and improved thermal insulation compared with dense concrete alternatives. The block has a smooth, uniform texture that supports clean coursing and simplifies wall construction.

This high-strength grade is suitable for external walls, separating walls, and partitions that need greater load-bearing capability. The block also provides thermal benefits that help limit heat loss in domestic and commercial buildings. Its aircrete structure offers good moisture performance and helps regulate temperature through thermal mass.

The block is easy to cut and shape with hand tools, improving installation efficiency on complex wall layouts. It offers stable long-term performance and maintains structural reliability in low-rise construction where a lightweight but strong block is required.

Installation Guide:

• Lay blocks on a prepared level mortar bed
• Keep joints consistent across each course
• Cut with standard aircrete tools for openings
• Allow mortar to cure before applying structural loads
• Follow guidance for moisture control on external walling
