H+H Celcon Blocks Used in Popular New Cheshire Development

Nantwich based property management firm Slater Homes Limited have recently completed an exclusive development in the delightful village of Bunbury in Cheshire using H+H Celcon Blocks. The five new luxury homes each have four bedrooms and already sold for in excess of £500,000 before the build was even completed.

The rural location presented a number of challenges for delivering the materials to site so local merchant Travis Perkins worked closely with contractor Slater Homes Limited to deliver the H+H Celcon Blocks in allocated time slots.

Slater Homes Limited said: “We were very happy to use the H+H Celcon Blocks as specified by the architect on the project, Stewart Thorley. Local supplier Travis Perkins in Nantwich always stock H+H Celcon Blocks so I knew the product could be relied upon to do a good job.

“The blocks were very easy to use and allowed us to build incredibly quickly – delivering great cost savings for us a small housebuilder.”

H+H Standard Grade Blocks were used in each of the five properties. Celcon Blocks are BBA certified, fire resistant (Up to 4 hours on 100mm walls or up to 2 hours if loadbearing) and have been classified 0 surface spread of flame and non-combustible to Class A1 (the highest class). Celcon Blocks are available in thicknesses from 75mm to 215mm.

H+H Celcon Blocks are also more resistant to sulfate attack than dense aggregate concrete blocks and increased protection from spalling – where blocks crack under the stress of constant freeze/thaw cycles during Britain’s cold and wet winter months.

Where they differ from their competitors however is through their superior thermal performance. By using H+H Celcon Blocks in this new development, Slater Thomas were able to achieve u-values of 0.2w/m2k with a 125mm cavity.

Linear thermal bridging is a major source of heat loss and the use of aircrete has a major benefit in reducing this by leakage through the masonry into the roof, floors and external walls.  Heat loss from junctions can now account for as much as 30% of the heat lost through the fabric of a building. It is therefore becoming increasingly important for housebuilders to consider the thermal performance of the building materials they are using.
