Aircrete blocks are high performance thermal blocks which are precision manufactured using autoclaved aerated concrete (AAC) by advanced technical processes, which can also be referred to as AAC blocks.
For thermal performance, strength and durability, Mannok aircrete blocks are the best performing thermal blocks in Ireland and with our expert Technical by Mannok team, we can help you achieve the most cost effective and efficient design for your project.
Mannok’s Aircrete High Ten thermal blocks have been specifically designed for applications where loading conditions require higher strength, such as high rise and commercial buildings.
Mannok’s Aircrete Seven block combines a very high strength to weight ratio with an excellent thermal performance making them ideally suited to multi-storey domestic and commercial buildings.
Mannok Aircrete Standard block combines optimum levels of thermal performance, strength and density to make it suitable for almost all on site applications, including party wall construction.
Mannok Aircrete Super block is the most thermally efficient block in the range and is used when a superior thermal performance is required for external walls.
Mannok Aircrete Coursing Units are ideal for use as a space filler, around doors and windows, for closing cavities and for making up between joists.
The full range of Mannok’s aircrete blocks are suitable for use as rising foundation walls below damp proof course in ground conditions up to and including MX3.2, high degree of saturation with freezing.
Achieve exceptional thermal performance thanks to Mannok aircrete blocks’ superb insulation properties.
Mannok’s aircrete blocks offer exceptional thermal performance thanks to their unique composition and the highly technical manufacturing process. Aircrete blocks are noted for their superb insulation properties, which ensures your building designs can achieve optimum performance.
Mannok thermal blocks’ unique properties achieve a far superior level of comfort for the residents of finished buildings. The blocks’ inherent thermal mass helps regulate daytime heating and night time cooling, making your home a more comfortable place to live all year round.
nZEB, Passive House standards and beyond are easily achievable with Mannok’s aircrete thermal blocks.
nZEB standards have been phased in to Irish regulatory standards, and developers and specifiers are tasked with designing and building more energy efficient homes than ever before.
Adopting a fabric first approach using Mannok’s aircrete blocks to combat thermal bridging is the most cost-effective route to achieving nZEB easily.
Our suite of Accredited Construction Details have been developed to help reduce heat loss through thermal bridging by up to 80%, and using these details can help significantly reduce the amount of renewable energy resources specified, ensuring significant capital savings.
Mannok aircrete blocks are manufactured using up to 80% recycled materials.
Made from up to 80% recycled materials, Mannok’s aircrete blocks have an A+ Green Guide Rating, making them an excellent choice for sustainable construction.
Using Mannok’s thermal blocks also increases the energy efficiency of buildings, thus reducing the lifetime carbon emissions.
The best performing thermal block in Ireland for combined strength, durability and fire performance.
The Mannok range of aircrete thermal blocks includes the Mannok Aircrete High Ten and the Mannok Aircrete Seven blocks with compressive strengths of 10.4N/mm2 (Category 2) and 7.5N/mm2, thus meeting all the regularity strength requirements across Ireland and the UK, including Ireland’s Technical Guidance Document A – 2012 – Structures, which requires blocks to have a compressive strength of 7.5N/mm2.
Mannok aircrete blocks are the only thermal blocks in Ireland which are certified for use below DPC for durability purposes.
All Mannok aircrete blocks have been tested for freeze/thaw resistance using recognised test methods and are certified for use in all ground conditions outlined in Table 14A of NSAI publication SR 325, up to and including MX 3.2, high degree of saturation with freezing.
No other thermal block on the Irish market complies with the requirements of Table 14A, which covers durability in masonry in finished construction.
Mannok aircrete blocks are also covered in standard IS EN 1996-2 2006 specification of masonry for durability. Table B1 of the Code clearly states that AAC blocks meet the requirements of MX 3.2.
Smart design with value engineering can help achieve optimum performance for less.
Smart design using Mannok’s thermal blocks mean energy efficient buildings can be excellent value for money. Ensuring design details are optimised, and with Mannok aircrete blocks’ exceptional thermal performance, savings can be made by reducing the need for expensive renewables.
Our expert technical team can help you with this fabric first approach to achieving more energy efficient buildings which meet nZEB standards using the most cost optimised designs.
Lighter, easier cutting and less on site waste with Mannok aircrete thermal blocks.
Aircrete thermal blocks are lightweight and easy to handle, which makes lifting and manual handling significantly easier and quicker on site. They are also much easier to cut than aggregate concrete blocks. Mannok Aircrete Coursing Units can further simplify work on site by reducing cutting requirements, thus minimising on-site waste and labour.
It’s the ease of handling and construction associated with these lightweight thermal blocks which have seen them become commonplace on sites across the UK for use in walls, foundations and beam and block floor applications.
SIMS by Mannok is a modern method of masonry construction which combines the benefits of Mannok’s aircrete blocks with a certified external insulation system. It’s a very straightforward construction method which utilises the simplicity of solid wall construction whilst enhancing the thermal performance and weather tightness of the building.
Thermal bridges occur at all junctions in the building fabric where the insulation envelope is broken by a non-insulating material. When ignored, thermal bridges can account for up to 40% of the total heat loss from a building. Mannok have developed a bespoke set of junction details, each with its own unique thermal bridging value, calculated by an NSAI-accredited Thermal Modeller. By using these details correctly heat loss through thermal bridging can be reduced to below 10% of the total heat loss.
Mannok Aircrete Thermal Blocks are the only thermal blocks in Ireland certified for use below DPC! The only block tested for freeze/thaw resistance to prove suitability for use below DPC and it is appropriate for use in severe exposure conditions, including high saturation with freezing, in accordance with EN 1996 Part 2.
There is currently some confusion in the Irish market about the requirement for 13N thermal blocks for durability purposes. In response to an industry issue relating to the durability and compliance of concrete blocks, the Association of Consulting Engineers of Ireland (ACEI) released an Advice Note to Structural Engineers with their recommendations.
