Heat transfer resistance or thermal insulation

In the new system of units, the temperature in degrees Celsius is denoted by the symbol ° C, while the temperature difference – symbol K. Hence the record – W/(m² • K) The reciprocal of the heat transfer coefficient 1 / k is called the heat transfer resistance or thermal insulation:

R = 1 / k…

Insulation of the house, part 3

This is currently being done, using generally a polyethylene or polyvinyl film (PVC). It is important, that the foil has tight edges, and that any electrical lines that may be mounted are airtight. A straight wall now looks like this:
– internal decking (impregnated),
– layer …

Insulation of the house, part 2

The temperature-keeping property is different for different materials. Porous materials, containing a lot of air, they conduct heat badly and are therefore good insulation. Still air is practically the best insulator, what you can get. In walls with large free spaces, it is always there …
