7.3 N/mm² AERATED CONCRETE WALL BLOCKS
(4.8 stars) • 10 reviews
Description:

Airtec Seven blocks possess high load-bearing capacity and excellent thermal performance. Perfect for higher-rise applications where thermal insulation and durability are required. These load-bearing Concrete Blocks are for construction up to 3 storeys in line with current Building Regulations and Structural Codes.

All Airtec products are BBA certified, ISO 9001 Quality, ISO 14001 Environmentally and BES 6001 Responsible Sourcing certified.

In common with all other Airtec aerated concrete blocks, they offer the very best possible dimensional tolerance category of 'Thin Layer Mortar B' (TLMB) but are perfectly suitable for conventional 10mm mortar joint construction.

Airtec blocks are available in ‘Standard’ texture finish only, providing a plain-faced, smooth, cellular texture which is a suitable background for accepting renders and plasters. Airtec blocks are not intended for paint-grade or fair-faced applications.

  • Inner and Outer leaf of cavity walls up to 3 storeys.
  • Internal partition walls.
  • Part E and Robust Standard Detail Party / Separating Walls.
