Which block do I need?

While choosing aerated concrete blocks you should pay attention both to the dimensions (block thickness) and main physical and mechanical characteristics such as:
average D density class and B compression strength class.
Among the range of UDK Gazbeton products there are two density classes: D400 and D500.For partition exterior walls it is applicable 300 mm and more thickness block, for interior walls and partitions 100 mm and more thickness block. 300 mm thickness blocks are appropriate for building of summer houses for season living or for wall construction with additional heat insulation. Our recommendation is to use the most economical and durable one lay wall construction, where aerated concrete wall meets all modern standards regarding thermal resistance without any additional heat insulation. For such wall construction you should use D400 blocks, which are the most universal in both strength and heat transmission aspects:
 
for the I temperature zone - AAC 400 mm and more thickness;
for the II temperature zone - AAC 375 mm and more thickness.

UDK TBM©

UDK TBM
UDK TBM thin bed mortar for aerated concrete is a pre-mixed cement based product for fast and accurate assembly of UDK wall blocks.
  • Work productivity while using UDK TBM +

    UDK TBM thin bed mortar for aerated concrete is an ideal alterrnative to the traditional cement and sand based mortar and differs in its plastics, applying convenience, less consumption. It also decreases labor intensity, work execution terms in comparison with traditional methods and has high adhesion to mineral surfaces.
  • To reduce heat loss using UDK TBM +

    Heat loss through traditional mortar joints can influence significally the total heat loss through the walls. While using UDK TBM thin bed mortar the joint thickness is 2-3 mm instead of 10-15 mm joint of traditional mortar.Due to the thin joints it is easy to eliminate so called "cold bridge" and decrease heat loss through the walls by 30%.
