tundub, et sa oled ikka meister, tugevalt argumenteeritud väidete püstitamises

aga vaata, siin on kaks asja 1) see ei omagi tegelikult mingit tähtsust kas minul on ehitusest erilist aimu või mitte 2) päris elus käivad asjad ikka ja endiselt nende füüsikavalemite järgi, mille järgi nad senimaani koguaeg käinud on.
seega, vaielda pole tõepoolest millegi üle. piisaks kui sa saaksid aru, mida tähendab paar mitte just väga keerulist mõistet. ja muide, mingite tootja lehtedega pole siin mingit pistmist. tunnen kaasa, kui sinusugune "meisterehitaja" hangib oma suuri teadmisi kuskilt tootjate kodulehtedelt.

Lambda (Thermal Conductivity)
Thermal conductivity (also known as Lambda) is the rate at which heat passes through a material, measured in watts per square metre of surface area for a temperature gradient of one kelvin for every metre thickness.This is expressed as W/mK. !!!Thermal conductivity is not affected by the thickness of the product!!!
The lower the conductivity, the more thermally efficient a material is.

R-Value (Thermal Resistance)
Thermal resistance is the ability of a material to prevent the passage of heat. It’s the thickness of the material (in metres) divided by its conductivity. This is expressed as m2K/W. If the material consists of several elements, the overall resistance is the total of the resistances of each element. The higher the R-value, the more efficient the insulation.
Example:
PIR Board: 0.022 W/mK and 100mm thick; R-value = 0.1 metres ÷ 0.022 = 4.54 m2K/W
Glass Fibre Roll: 0.044 W/mk and 100mm thick; R-value = 0.1 metres ÷ 0.044 = 2.27 m2K/W
