Description

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.

AIRTEC party wall block:

  • 3.6N block designed to offer superior thermal performance along with being suitable for acoustic party/ separating, flanking or fire resistant walls.
  • Can be used in Robust Detail party wall construction between dwellings and when in accordance with Building Regulations (E&W) Approved Document E.

AIRTEC seven wall block:

  • 7.3N 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.
  • Additionally, the low weight of these blocks and ease of handling offer quick, easy and cost-effective method of construction.
  • Suitable for external cavity or solid, loadbearing and non-loadbearing, party/separating, flanking, partition, fire resistant or foundation (below dpc) walls.

AIRTEC standard wall block:

  • 3.6N block designed to offer superior thermal performance along with the structural capacity for up to three story construction.
  • Offer the same thermal conductivity value of a typical 2.9N strength aerated block; which offers medium strength and high thermal performance in one block.
  • Suitable for external cavity or solid, loadbearing and non-loadbearing, flanking, partition, fire resistant or foundation (below dpc) walls.

AIRTEC ten wall block:

  • 8.7N block designed to offer the highest structural capacity for multi story construction where 10.4N loadbearing performance is required.
  • Manufactured to BS EN 771-4 (Category I) which allows the use of an enhanced partial safety factor in structural calculations to BS 5628 and Eurocode 6.
  • Suitable for external cavity or solid, multi-story loadbearing, party/separating, flanking, partition, fire resistant or foundation (below dpc) walls.

AIRTEC XL wall block:

  • 2.9N block designed to help reduce the build time on-site, allows the builder to minimise the amount of secondary insulation required to meet the thermal requirements within the Building Regulations (E&W) Approved Document L.
  • The inner leaf of AIRTEC XL blocks give the builder the option of using a 75 mm cavity, either partially or fully filled whilst achieving a U-value: 0.30 W/m²K.
  • Suitable for external cavity or solid, loadbearing and non-loadbearing, flanking, partition, fire resistant or foundation (below dpc) walls.

Complies with the latest European Standard BS EN 771-4, which exceeds the performance criteria of BS 6073-1.

Freeze/thaw resistant.

Product Options

Accessories:

- 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.

- Benefits:

  • 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.
  • Reduces pattern staining.

- Applications:

  • Internal and external leaf of cavity walls.
  • Loadbearing and non-loadbearing walls.
  • Partition walls.
  • Thin joint construction.
  • Fire resistant walls.
