Thermal conductivity: design task for ground-bearing floors and screeds
Below a screed, thermal conductivity depends on full bearing, access routes and placement of the distribution layer.
In ground-bearing floors and screeds, thermal conductivity requires design loads and the absence of point supports; also check substrate evenness.
Thermal conductivity: application boundary in ground-bearing floors and screeds
In ground-bearing floors and screeds, thermal conductivity has an important boundary. A tabulated conductivity is not the thermal resistance of the finished construction.
For thermal conductivity in ground-bearing floors and screeds, address this specific risk: impact during placement or premature traffic over an unprotected layer.
Thermal conductivity: evidence for ground-bearing floors and screeds
For ground-bearing floors and screeds, the thermal conductivity source states: For D130, the declared maximum is 0.046 W/(m·K) at (10±1) °C and 0.048 W/(m·K) at (25±1) °C.
For thermal conductivity in ground-bearing floors and screeds, apply this principle. The calculation must account for the test temperature and the condition of the complete assembly, rather than relying on one table value.
Thermal conductivity: detailing for ground-bearing floors and screeds
The ground-bearing floors and screeds drawing develops thermal conductivity through two decisions: the load-distribution build-up and designated access routes; then substrate preparation.
For thermal conductivity in ground-bearing floors and screeds, dimensions and interface materials belong in the design, not in an improvised site decision.
Thermal conductivity: inputs for ground-bearing floors and screeds
Before assessing thermal conductivity in ground-bearing floors and screeds, obtain design temperatures, moisture conditions, layer thicknesses, thermal bridges and the calculation method.
For ground-bearing floors and screeds, the verifiable thermal conductivity requirement is to record the design temperature, adopted conductivity and value source in the design report.
Thermal conductivity: installation in ground-bearing floors and screeds
The installation rule for thermal conductivity in ground-bearing floors and screeds is to process products on a level bench and cover each area immediately after acceptance.
During ground-bearing floors and screeds work concerning thermal conductivity, check installed thickness and continuity before the next layer hides the insulation.
Thermal conductivity: accepting work in ground-bearing floors and screeds
Acceptance of thermal conductivity in ground-bearing floors and screeds starts by matching delivery labels, drawings and the installed layout.
For thermal conductivity in ground-bearing floors and screeds, close the identified risk with a photograph, measurement or record, not a verbal explanation.
The final ground-bearing floors and screeds criterion for thermal conductivity is that the design value is traceable from the data sheet to the installed layout.
Thermal conductivity: conclusion for ground-bearing floors and screeds
In ground-bearing floors and screeds, foam glass delivers its thermal conductivity benefit through a coordinated detail, not one schedule entry.
The ground-bearing floors and screeds workflow for thermal conductivity is to evidence the property, issue the detail, accept installation and retain concealed-work records.
