Performance properties

Aircrete products provide effective solutions for walls, floors and below the ground. The high level of performance achieved by aircrete blocks, combined with an extensive product range, ensures that cost effective solutions for wall, floor and below ground constructions can be achieved.

Fire resistant

All aircrete blocks provide excellent fire protection. They are classified as A1, non-combustible in accordance with BS EN 771-4.

Aircrete does not burn and can be used to contain or prevent the spread of fire within a building. As well as being BBA certified, aircrete has up to a 4 hour fire resistance can be achieved with a regular 100mm thick block, or 2 hours if loadbearing. Aircrete has Class O surface spread of flame and is non-combustible to Class A1 (the highest class). With this level of resistance aircrete becomes the perfect choice for any building, but especially those where we live or care for less mobile persons.

Thermal performance

Aircrete blocks offer high levels of thermal performance that satisfy the requirements of Building Regulations and the needs of builders and designers. 

Aircrete's high level of thermal performance means U-value requirements are met more easily, reducing or eliminating the need for additional insulation, producing significant cost savings. A complete insulation solution is achievable using Aircrete blocks. Aircrete's inherent thermal qualities provide a highly effective barrier against the penetration of moisture and frost. When combined with a suspended beam and Aircrete block floor, they can achieve a possible 40% saving in floor U-values. Building with Aircrete gives greater scope to build thermally efficient warm houses that exceed the requirements of the current Building Regulations.

Moisture resistant

Aircrete blocks provide good resistance to the passage of moisture. Independent tests have indicated that aircrete blocks make water penetration extremely difficult.

Frost resistant

The micro-cellular structure of aircrete, incorporating millions of pockets of trapped air, gives the material protection against the effects of frost.

Durable and strong

Aircrete products are very strong as well as lightweight and may be used in loadbearing walls for a structurally sound building.
