H+H’s ‘celcon elements’ are storey-height panels of aircrete — which have been used by Barratt to build circa 600 new homes — and is one of more than 40 MMC systems now accepted by NHBC.

Oliver Novakovic, technical and innovation director at Barratt, commented: “We have seen excellent construction quality onsite with the H+H celcon elements, and are delighted that we are helping to provide high-specification new homes by embracing MMC.”

The product is said to have excellent thermal performance with reduced heat loss at thermal bridges, and is usually used with Roofspace Solution’s ‘I-House’ system for the construction of domestic homes of up to two storeys, with rooms in the roof.

Cliff Fudge, technical director at H+H, said: “We are now at a stage where we have a proven build quality and speed, along with a reduced number of reportable items, and look forward to continuing our work with NHBC and Barratt in the future.”

Richard Lankshear, innovation manager at NHBC, added: “There is a widely recognised need to drive housing supply in the UK and we have worked closely with builders and government for many years to address this.

“We expect to see more innovative solutions emerge over the next decade, and NHBC’s thorough and rigorous approach to the acceptance of new MMC systems that meet our standards, will help bring benefits and certainty to manufacturers, developers and builders.”
