H+H UK Ltd

H+Hs Thin-Joint System has been used in the construction of a Passivhaus development of 16 semi-detached houses and 12 sheltered accommodation apartments at Cameron Close, Freshwater, on the Isle of Wight.

Phase one consists of a mix of two storey 2 and 3-bedroom affordable and retirement houses. The external cavity walls are constructed with a Thin-Jointed aircrete inner leaf and either brick, flint or cladding to the outer-leaf, topped with a pitched, tiled roof.

In this guide we bring together the two areas for using aircrete, the design process and Building. This brochure has been written to help architects and specifiers achieve the most efficient designs using H+H UK products, whether for low-rise housing or multi storey buildings.

Thin-Joint construction combines the use of large format, accurately dimensioned aircrete blocks and quick setting mortar to create a highly productive and cost-effective building system.

Celcon Vertical Wall Panels are storey-high panels of aircrete, designed to allow an exceptionally fast build method. Manufactured to the design storey height of a house with a width of 600mm and a thickness of 100mm, Vertical Wall Panels are designed to be craned into place onto a bed of mortar on standard foundations. Blocks are joined using Thin-Joint Mortar with 2mm (3mm) joints, providing an extremely airtight finish and panels can be cut on site to accommodate design details.

The i-House system using H+H Celcon Vertical Wall Panels has been used on a re-development of a residential site in Stanpit in Dorset. The i-House system introduced developer and contractor Karm Homes to the concept of Modern Methods of Construction (MMC) while also providing the familiarity of a traditional building material. The full i-House system package was used for each unit, comprising the structural inner skin, insulation, floor cassettes, roof cassettes, soffitsand facias. The i-House system is manufactured offsite by Roofspace Solutions who also supply a 3-person team and crane operator to create each structure.

Davis Langdon were commissioned to undertake a study to provide a detailed comparison between Light Gauge Steel (LGS) Frame construction and H+H UK Ltd thin-joint masonry construction using aircrete units. The study focused on a comparison of costs, together with speed of build, programme, robustness, thermal mass and other benefits of masonry over framed construction.

H+H products were selected for this project due to the aircretes high thermal performance which helps meet Passivhaus standards. Passivhaus is achieved by the application of high levels of insulation, avoidance of thermal bridging within the structure, low levels of air leakage all of which are qualities addressed with the use of the H+H range of Celcon Blocks.

The i-House System incorporating Celcon Vertical Wall Panels was specified for use on 164 units on the Norton Farm site in Bromsgrove. The i-House System provides the speed of offsite construction with the familiarity of a traditional build. Construction of 164 units with a mixture of one, two and three bed homes in terraced, semi-detached and detached form, of which 98 are to be affordable homes for Bromsgrove District Housing Trust. The main attraction of the i-House System both on site and for others within the supply chain is that it is very similar to traditional build in its materials and approach so there is no dramatic change to working practices for the follow-on trades. The plumber, electrician and carpenter are all used to working in aircrete buildings.

A prestigious development of five luxury apartments constructed to Passivhaus principles using the H+H Thin-Joint System. Masonry Frame Systems specified H+H Jumbo Bloks primarily because it is what was needed to meet the demands of this Passivhaus construction. H+H Jumbo Bloks offer an advanced thermal performance which adheres to Passivhaus standards.

With their thermal, acoustic and load bearing capabilities, H+H products offer simple solutions to the latest Building Regulations. In addition to being lightweight they also have the benefits of high resistance to fire, sulfate attack, frost and water penetration.

Bottle Lane is a private custom build home designed and constructed by Revolution Homes. The four-bedroom, detached house stands on the site of the clients old property which was demolished to make way for a new more acoustically and thermally efficient build. As the client was overseas for the duration of the build, they wanted a company that could offer a full system build package from conceptual design to a finished product.

Modern Masonry package in which a customer sends in their drawings for a new home. We assess them and make recommendations for compliance and energy, thermal bridging and recommend the appropriate block type to use for the build.
