Thin Joint Masonry | Aircrete Walls

Thin joint blockwork (thin joint masonry) is a fast, clean, accurate system for construction using autoclaved aerated concrete blocks of close dimensional tolerance with 2mm-3mm mortar joints.

Thin Joint Masonry is a fast, clean, accurate system for construction using autoclaved aerated concrete blocks of close dimensional tolerance with 2mm-3mm mortar joints.

Thin layer mortar is a pre-mixed cement-based product that only requires the addition of water to make an easilyapplied mortar. It differs from general use mortar in that it sets more rapidly, thus giving early stability to the construction. It provides an alternative to traditional sand/cement mortar and allows the depth of the mortar to be reduced from at least 10mm to 3mm or less.

With similar characteristics to traditional blockwork construction, skilled bricklayers will need minimal training to adapt to this system. The use of a thin joint blockwork system offers multiple benefits that can be felt through the supply chain in terms of the following:

Faster build speed

A thin layer of mortar is applied to autoclaved aerated concrete blocks using a serrated scoop, allowing for a quick and accurate application.

Increased productivity

Use of a thin joint system dramatically increases productivity as walls will typically be stable after 60 minutes. This will allow whole wall to be built in less time and enables earlier installation of other components, such as floors and roof timbers.

Improved thermal performance

Heat loss through mortar joints can be reduced by 70% through the use of thin joint blockwork. By reducing the amount of mortar needed, you are reducing the effects of cold bridging.
