Application

Suitable for external cavity or solid, loadbearing and non-loadbearing, party/ separating, flanking, partition, fire resistant or foundation (below DPC) walls.

Description

7.3 N aerated concrete block offers the highest structural capacity of the AIRTEC range for construction up to three stories in line with current Building Regulations and Structural Codes.


Features and benefits:

  • Freeze/ thaw resistant.
  • The low weight of these blocks and ease of handling offer quick, easy and cost-effective method of construction.
  • Complies with the latest European Standard BS EN 771-4, which exceeds the performance criteria of BS 6073-1.
  • Autoclaved Aerated Concrete (AAC) wall blocks are manufactured to the traditional coursing height of 215 mm and to a length of 620 mm, with a range of thicknesses available from 75–215 mm all with a dimensional accuracy suitable for both general purpose and thin-joint mortar construction.
  • Accessories include AIRTEC Brickettes: Autoclaved Aerated Concrete (AAC) coursing units designed to offer brick-sized (65 x 215 mm) products for use as infill around doors and windows. It's benefits include the following: Eliminates the need for cutting down full-size blocks, maintains material continuity throughout the entire wall thus avoiding the effects of cold-bridging and differential movement which can arise from the use of dissimilar materials, maintains uniform thermal performance throughout the entire wall, reduces the need for cavity closers and reduces pattern staining.
  • AIRTEC Brickettes can be applied on internal and external leaf of cavity walls, loadbearing and non-loadbearing walls, partition walls, thin joint construction and fire resistant walls.
  • BBA certification - 06/4309.
