Considering Thermal Insulation for Concrete Block Walls ...

22/03/2021  Recently I was involved in various discussions regarding the possibilities for providing thermal insulation to the solid concrete, and concrete block, external and retaining walls of several residential buildings. For lightweight framed and panel wall construction, the thermal performance of the insulation is the primary consideration. With heavyweight wall construction (normally concrete ...

INSULATING CONCRETE MASONRY WALLS - NCMA

As for the furring used for interior insulation, the thermal resistance of the concrete masonry webs and any grouted cores should be accounted for when determining the thermal performance of the wall (see TEK 6-2C, ref. 3, for tabulated R-values of walls with core insulation). When using core insulation, the insulation should occupy all ungrouted core spaces (although some rigid inserts are ...

While these blocks are more expensive than a conventional concrete block, they feature far superior thermal values. For example, a conventional concrete block has a thermal conductivity (λ value) of 1.13W/mK; while a light weight concrete block can have a λ value as low as 0.11W/mK, which is nearly ten times more thermally efficient! This can have a dramatic effect on the depth of ...

the myth of stone walls as insulation carbon limited

05/03/2007  But with stone, the thermal resistance is so low that in order to offer a reasonable level of insulation, the walls need to be unrealistically thick. A typical 500mm thick stone wall, for example, has the equivalent insulating value of only 15mm of rockwool. In comparison, to pass building regs a new house in the UK needs the equivalent of 150 ...
