Calculator calculating bath roof insulation thickness

It's no secret that erected by all the rules Bath must have excellent thermal insulation in order to quickly heat up and cool down for a long time. And if the walls everything is quite clear, the insulation of ceilings and roof structures, many do not pay enough attention. But through these "leaves" of up to 40% of the heat! Especially for readers HouseChief we have prepared a handy online calculator to calculate the necessary insulation.

Calculator for calculating the desired thickness of the roof insulation bath

Explanation of the calculation

Basic formula for calculation is as follows:

R = s / λwhere

R- the required resistance to heat transfer, m² · K / W;

s - thickness of insulation, m;

λ - thermal conduction coefficient of the material (W / mK).

You are only required:

  • choose what kind of overlap will be carried out the calculation: for the roof ramps or the ceiling;
  • select the type of insulation from the provided list of popular heaters;
  • determined by the map-circuit the desired value of the thermal resistance depending on their type and the selected region of overlap;
  • specify the parameters of the inner skin of the attic space to calculate the roof ramps and finishing options from the attic and interior - to calculate the attic floor.
  • specify whether you will use penofol as additional insulation.

Final result is presented in mm.
