1. autoclaved, aerated concrete (AAC) 2. (cel)lular (con)crete
(CELCON). One of the lightest forms of concrete with structural, thermal, sound, fire and freeze/thaw properties, extensively used in Europe where known as ‘gasbeton’. Used in the UK since the 1950s; today known as ‘aircrete’. Comprises pulverised fuel ash (PFA), sand, cement, aluminium powder, lime and water. Used as blocks in a range of thicknesses and face formats for internal and external walls above and below dpc and as infill in beam and block floors; used as a material for reinforced floor elements.
Building the homes of tomorrow. Today
H+H has been supplying our aircrete products into the market for over sixty years building a reputation for our distinctive partnership approach and for adding value at every stage of the supply chain.
From initial planning through design, distribution and construction, H+H supports customers at every stage of the building process, recognising that from genuine partnership comes responsive efficient and reliable customer service.
We manufacture the highest quality, technically innovative aircrete components, but more than that, we specialise in the design and construction of high-performance, durable, cost effective structural walls.
With their thermal, acoustic and load bearing capabilities, H+H products offer simple solutions to accommodate the latest Building Regulations – and looking further ahead, to meet the Future Homes Standard due to come into effect in 2025.
Our aircrete products can even accommodate the needs of technically demanding building methods such as Passivhaus. We have been working with housebuilders to develop energy efficient house designs for decades.
H+H is committed to sustainability. Up to 80% of the raw materials used in the manufacture of Celcon Blocks are recycled products in some form. We also ensure that 99% of all raw materials are sourced from UK suppliers reducing the need for transportation.
H+H International has committed to produce net zero carbon emissions by 2050 and we are using third-party verified Science-Based Targets to measure the impact of our actions.
Since setting up our first research and development laboratory in 1969, H+H has been at the forefront of aircrete research
A totally focussed strategy, combined with specialised resources, has enabled us to undertake pioneering work with solutions including Celcon Blocks, the H+H Thin-Joint System and the H+H MMC build solution with Vertical Wall Panels.
