Building Extensions with Aircrete

H+H aircrete provides a versatile solution for residential extensions, from rear and side-return extensions to multi-storey additions. Combining thermal performance, structural strength and easy handling, aircrete can be used to create durable external walls that integrate with a range of traditional finishes.

Residential extensions need to integrate effectively with the existing property in both appearance and construction. Aircrete can be used with common cavity wall and twin-block construction methods and is compatible with traditional brick and rendered finishes, providing flexibility when designing new walls to complement the existing building.

Aircrete's thermal properties make it well suited to external walls for residential extensions. Combined with appropriate cavity insulation, H+H aircrete can help create wall constructions designed to meet current thermal-performance requirements.

Careful detailing is required where a new extension meets an existing building. Differences in foundations and structural movement can create a risk of cracking, so appropriate movement joints should be incorporated to accommodate differential movement between the new and existing structures.
