Thomas Armstrong (Concrete Blocks) Limited joins the Aircrete Products Association

Since 2004, we have been successfully producing the 'Airtec' range of aerated concrete products in our state of the art facility near Catterick in North Yorkshire. Having established ourselves in the UK market by offering a high quality product and having gained all necessary technical, quality and environmental certifications, we are now taking the next step forward by becoming full and active members in the UK's national association for aerated concrete producers, the "Aircrete Products Association".

The Aircrete Products Association (APA) is the single, authoritative body in the UK representing aerated product (aka 'aircrete') manufacturers. The APA is an exceptional resource offering a wealth of experience, knowledge and technical expertise in the manufacture and application of aerated products throughout the UK. Furthermore, the association provides excellent guidance in the use of aircrete, offering aircrete solutions to current and future building regulations and showing how this sustainable and versatile product can offer simple but effective solutions to the continuing drive towards low energy, zero-carbon housing.

The APA is in itself a member of the European Autoclaved Aerated Concrete Association (EAACA) which brings together all of the national associations across Europe. This ensures that all of its members are fully informed and remain at the forefront of all current and future building legislation, technical standards, health & safety good practice and innovations.

Our membership of the APA not only enhances our customer support and technical resources, but also demonstrates our commitment to aerated products as an excellent building product which will play a major role in delivering sustainable, efficient and affordable low energy housing long into the future.
