Do you want to correctly calculate the thickness of the insulation? We keep to ourselves the table of resistance to heat transfer!

When insulating the roof, it is necessary to be guided by the following regulatory documents:

• SNiP II-26-76 "Roofs";
• SNiP 23-02-2003 "Thermal protection of buildings";
• SNiP 23-01-99 "Construction climatology"

You can calculate the thickness of the insulation using tables 1 and 2 below.

EXAMPLE: For St. Petersburg, the reduced resistance to heat transfer Rо is 4.6, which corresponds to 200 mm of mineral insulation.

I hope this information was useful to you!
