Thermal Performance

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 Made Easy

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.

Sustainable

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.

Structural Performance

Strength

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.

Durability

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.

Cost-effective

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.

Ease of Construction

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.
