Consider a brick simply as a 'wall element' and the question arises, does one need an inner leaf and an outer leaf? The simple answer, of course, is no, as long as the issues of structural behaviour, weather resistance and thermal performance are met. Starting from this standpoint, Hanson Brick has been involved with developments over a number of years.
215mm solid clay through-the-wall units Hanson developed these square clay units in its Belgian factories. The format, known as Maxi Block, allows the construction of solid traditional masonry which has a very high load-carrying capacity and excellent thermal mass. Standard format 215 x 102mm units are available to supplement the square bricks and allow construction of masonry in traditional bonding patterns where both headers and stretchers are available.
Solid masonry walls are ideal for use with the popular offthe-frame cladding building technique, in which a structural steel or concrete frame forms the main superstructure. A 215mm clay wall is then constructed for the full height of the building, eliminating the need for expensive fixings and shelf angles. This technique also relieves the superstructure of the weight of masonry, thus reducing the dimensions of structural members.
This product is also beneficial for the construction of freestanding and retaining walls.
Composite through-the-wall masonry units Hanson Brick is developing a composite masonry unit which addresses the problems of in-situ construction, workmanship and the design requirements of a cavity wall.Thermal insulation as well as a reduction in the risk of rain penetration through poor-quality bricklaying are just two of the design parameters which are being considered in the development of this form of masonry.
Additionally the single 'cavity wall unit' allows a much higher rate of laying when compared with the complex brick/block/ insulation system.
