External Walls: Solid Wall Construction
Celcon Blocks of 200 mm width or greater can be used for solid wall construction and standard mortar or Thin-Joint methods are both appropriate. Solid wall construction was traditionally viewed with concern in the UK because of the issue of water penetration. However, owing to its closed cell structure, aircrete is resistant to water, making a solid wall structure a fast, thermally efficient and extremely airtight option which easily meets the requirements of Building Regulations Approved Document C.
Celcon Blocks of 200 mm width or greater can be used for solid wall construction and standard mortar or Thin-Joint methods <link to thin-joint method> are both appropriate. It will be necessary to add insulation to the aircrete wall either internally or externally and the wall structure should also include a durable, permanent external finish such as render, brick slips or other cladding – all of which can be applied with or without external insulation.
Celcon Elements can also be used for solid external walls, providing the fastest method of build and unparalleled airtightness. As with Celcon Blocks, walls will need insulation and an external finish.
