Overview

Celcon Blocks have been used in the construction of an extension to an Edwardian terraced home in Wimbledon. The owners required more indoor space so decided to complete a rear extension to add more space. Built using H+H Celcon Blocks the extension has made the house noticeably warmer and improved the sound insulation.

The owners already had planning approval so contacted Westminster Building Company to check their availability. The company was able to start on the job quickly, and the whole process from point of contact to completion of the extension took just four months.

Benefits of Celcon Blocks

Will Clark, Director of Westminster Building Company, explains why they used H+H aircrete: “H+H is a big name, so I didn’t give it a second thought when using their Celcon Blocks. I knew I was buying good quality building materials that are light to handle and easy to use.

“Technically speaking this was a job that required some forethought, as the homeowner wanted the extension to be futureproofed for building up a storey. Also, one of the next door neighbours was planning for a rear extension to their home.

“This meant that we built a 300mm wall with two layers of 100mm Blocks with a 100mm cavity wall insulation using 7 newtons thermal Celcon Blocks on the inner skin. This was both to facilitate future upward building and to ensure that the neighbours plans weren’t mitigated.”

Celcon Blocks of 200mm width or greater can be used for solid wall construction and standard mortar or Thin-Joint methods are both appropriate. It will be necessary to add insulation to the aircrete wall and a durable, permanent external finish such as render, brick slips or other cladding – all of which can be applied with or without external insulation.

As the UK’s largest manufacturer of aircrete, H+H is able to provide technical information for contractors thinking of using aircrete for their next project.

All 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 manufactured in 440 x 215mm and are available in thicknesses from 75 to 215mm.
