Solar Blocks – Lightweight Aircrete Blocks for External Wall Construction

Celcon Solar blocks have been specially developed to offer cost effective traditional solutions to the energy conservation requirements of the Building Regulations (Part ‘L’).

Solar blockwork has been used extensively in domestic dwellings since the early 1980s and has proved to provide economic, technical risk-free constructions in both cavity and solid walling.

For the site operative, Celcon Solar yields many benefits. The blocks are light and easy to handle. Solar blocks meet the CONIAC manual handling requirements for Health and Safety.

The Solar block can be identified by its distinctive V-Key which runs part the way across the face of the block leaving an unmarked area at either the ends or the top and bottom of the face.
