Quinn Lite AAC Thermal Blocks

Quinn Lite blocks are high performance thermal blocks which are precision manufactured using autoclaved aerated concrete (AAC) by advanced technical processes, which are also commonly referred to as aircrete blocks.

For thermal performance, strength and durability, Quinn Lite blocks are the best performing thermal blocks in Ireland and with our expert Technical by Quinn team, we can help you achieve the most cost effective and efficient design for your project.

Quinn Lite Benefits

175% more thermally efficient

than any other thermal block manufactured in Ireland

Thermal Performance

Achieve exceptional thermal performance thanks to Quinn Lite’s superb insulation properties.

Thermal Performance

Quinn Lite 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.

  • Insulates 10 times better than standard concrete blocks
  • Reduces heat loss through thermal bridging by up to 80%
  • More thermally efficient than lightweight aggregate blocks
  • Achieves up to 200% better Psi values than other thermal blocks, such as lightweight aggregate blocks
  • Quinn Lite 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.

Structural Performance

The best performing thermal block in Ireland for combined strength, durability and fire performance.

Structural Performance


The Quinn Lite range includes the High Strength Ten and the 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.


Quinn Lite blocks are the only thermal blocks in Ireland which are certified for use below DPC for durability purposes.

All Quinn Lite 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.

Quinn Lite 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.

Super Insulated Masonry Solution

Cost Effective, rapid build solution for the Irish construction industry

SIMS by Quinn is a modern method of masonry construction which combines the benefits of Quinn Lite thermal 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.

Combating Thermal Bridging with our Accredited Construction Details

Reduce heat loss through thermal bridging by up to 80% with Quinn Lite

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. Quinn Building Products 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.
