Crest Porit Blocks on site

Crest supply a great range of energy efficient aerated concrete blocks.

Our Crest Aerated concrete blocks have very good physical building properties. These blocks are non-flammable, they are impermeable to frost and moisture and provide excellent industry leading insulating properties. Above all, however, our aerated blocks are quick and efficient to lay. In practice, this is a decisive argument for contractors to use these blocks, as this results in a faster, higher quality construction.

Our Aircrete Block products are manufactured to comply with European standards EN 771-4:2011 (CE-marked).

Ytong blue sky site

For house construction, commercial and industrial buildings.

Autoclaved Aerated Concrete (AAC) blocks are perfect for; foundations, inner leaves of cavity walls, dwelling partitioning walls, plus internal, external and fire walls in both load bearing and non load bearing designs. These building blocks have been used for over 40 years and are proven as being highly efficient for both house construction and for commercial and industrial buildings.

Energy Efficiency

All of our aerated blocks have superb technical properties and are providing outstanding energy efficiency results. When aerated blocks are laid using the thin bed joint system, efficiencies reported to us are as low as .09 due to increased air tightness and enhanced thermal insulation.

High construction speed and savings

In addition to the versatility and energy efficiency properties, the aerated blocks are characterised by its ease of working and construction. The aerated concrete blocks can easily be sawn (even with a hand saw!). This results in a higher construction speed which can deliver cost savings, particularly in developments. Notable savings can also be made in faster weather proofing, lower scaffolding costs and less on-site waste. In addition when using the thin bed joint application you use up to 5 times less mortar which means less materials, less preparation, less mixing and less mortar to move around site which provides the convenience to mix at point of construction.

There are many construction advantages of aerated blocks over traditional blocks. They are lightweight meaning less strain on the workforce and them being easier to move around site and lay plus you are not restricted to how many courses you can lay at any one time (when using thin bed mortar joints).  AAC blocks are simple to cut and chase and they have unlimited finishing possibilities all providing a much cleaner working environment too.
