Building blocks

Celcon High Strength Grade blocks are made from aircrete and designed for use where higher compressive strength is needed, such as in multi-storey buildings and foundations. Key features include a compressive strength of 7.3N/mm², thermal conductivity of 0.18 W/mK, and density of 730kg/m³. Available in widths from 100 to 355mm

Celcon Foundation Blocks can be used to support 3-storey buildings and are suitable for supporting solid or cavity walls, framed constructions or suspended floors, including the H+H Beam and Block system. Available in Standard Grade (3.6N/mm2) and High Strength Grade (7.3N/mm2). The blocks can reduce heat loss from ground floors

Celcon Solar Grade blocks for walls are principally used where enhanced thermal performance is required. They are identified by the distinctive painted blue line. With a superior thermal conductivity Solar Grade blocks are suitably load-bearing for 2-storey buildings and can be used below DPC. Thicknesses from 100 to 215mm

H+H’s Celcon Blocks High Strength Grade are ideal where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multi-storey buildings: available in thicknesses from 100mm to 355mm; high Strength (7.3N/mm2 – identified with a black stripe on the

H+H Jumbo Bloks are large-format aircrete blocks designed for use in thin layer construction to enhance build speed on site. As few as 6.3 blocks are required to complete 1m² of walling: large-format blocks reduce the number of units required per square metre; compatible with thin layer construction for faster build times; multiple compressive

Celcon coursing units are made from aircrete and designed for use in both internal and external walls, matching the material and applications of standard Celcon blocks. Suitable for infill above doors and windows, at floor and ceiling levels, and for making up between joists. Not intended as the sole masonry unit in load-bearing walls. Available

Celcon Standard Grade aircrete is extremely versatile and can be used below DPC as infill for beam and block flooring systems, as well as above the ground in the walling applications listed. Celcon Standard Grade blocks are BBA certified and available in 75-215mm thicknesses. Due to its all-round performance, it is possible for 100mm Standard

Celcon Plus Blocks are an alternative to the 440 x 215mm face format block and are suitable for the same applications. The Plus range is produced using the latest manufacturing technology, ranking them amongst the most dimensionally accurate blocks available. This makes them ideal for use with H+H's thin-joint system

Precon blocks are dense, lightweight and precision-made. They are provided in a range of sizes from 100 to 215mm thick. Specials are available, including quoins, half quoins and cavity closers. Highly versatile, these blocks are suitable for a range of applications, including external walls (above and below damp courses), partitions, separating

Precon blocks are made from concrete at a modernised plant in Coatbridge, Scotland, and are available in standard dense, paint grade and lightweight types. Manufactured in a range of sizes and strengths, these blocks are suitable for structural and non-structural wall construction and flooring, meeting CE quality standards

A new, 2,240m2, religious building near Birmingham is being constructed using a lightweight steel frame structure with H+H Celcon Blocks used as a thermally efficient, durable and fire-resistant infill material. This structure provides for a large open interior and steelwork was used as the load-bearing structure to provide the large spans

Architects designing a single bungalow in Norfolk to Passivhaus standards specified H+H’s Celcon Block Standard Grade for the internal leaf and external leaf to the timber boarded elevations on the structure. H+H products were selected due to delivery time, speed of construction, stability and thermal mass. 140m2 of aircrete blocks were supplied

The Riverdale Park development is currently under construction in Doncaster, bringing 139 new houses to the banks of the River Don. Led by Harron Homes, a construction company building luxury homes across the North Midlands and Yorkshire, the project is expected to be completed over the next four years. Built on an old Polypipe factory site, the

H+H is participating in a project trialling different methods of meeting the energy performance required by the Future Homes standard. Project 80 is a pioneering development of new homes for Midlands Heart Housing Association. The homes are being built to Future Homes standards – requiring a reduction of 75-80% in carbon emissions over current

A 4-bedroom, acoustically and thermally efficient house was being built as a complete system build by Revolution Homes. The client specified a masonry fabric shell along with the thermal mass benefits associated with it. The H+H Rå Build method of thin-joint aircrete construction was selected by Revolution Homes for the project due to its

Hill Bespoke, which uses cutting edge techniques to provide premium housing solutions. specified the RåBuild method of construction, which uses the H+H Thin-Joint System, on four new build homes in Cambridgeshire. RåBuild, an all-in-one approach to building from H+H UK, takes full advantages of the properties of aircrete to allow for the quick

Elan Homes chose H+H Celcon Solar Grade Blocks to construct ultra-energy efficient homes. Our blocks were specified by Elan Homes for the internal leaf of the cavity wall of 86 homes being built at its Redwood Gardens development in Blackpool. All H+H aircrete products have excellent thermal properties, but our Solar Grade Blocks are designed to

Celcon Foundation Blocks were supplied to SJ Roberts for the Sweetlake Meadow development of 175 new homes in Shrewsbury, as sustainability was a very important factor for this project. Calfordseaden, an independent construction and property consultancy firm, conducted a Foundation Cost Comparison Study, which identified that constructing foundations using aircrete blocks is more cost-effective

H+H Aircrete blocks and the Thin-Joint method of construction were used for a robust, energy efficient self-build project. The site posed a number of logistical challenges, primarily the constrained size and shape of the garden plot. Therefore, aircrete’s inherent properties of being lightweight and easy to lay and manipulate on site proved ideal

Using aircrete, a certified modern method of construction, main contractor B.W Bellis was able to complete the blockwork on a large six-bedroom self-build property in Wales within six weeks. Apart from some technical assistance from H+H on working with aircrete, all of the blockwork was laid by a single worker during this time. Main contractor

H+H's Rå Build method was used for this affordable and retirement home mixed development, with the inner leaf, first floor and roof installed ahead of the external leaf. The homes were required to achieve level three in the Code for Sustainable Homes

Sherborne Homes in Cheltenham, specified the Thin-Joint System, provided by H+H, for its housing association build.
