About the Facade Insulation Calculator

Professional tool for calculating building insulation efficiency

Calculator Purpose

This calculator was developed to help make informed decisions about facade insulation...

The calculator takes into account wall construction, thermal parameters...

Calculator Features

Calculate heat loss through uninsulated walls...

Determine the most cost-effective type and thickness of insulation for your conditions

Calculate annual savings and payback period

Compare different types of insulation

Clear graphs showing payback period... depending on insulation thickness

Consider temperature conditions in your area...

Calculation Methodology

The calculator uses methodology according to DSTU 9191:2022...

  • thermal resistance of each wall layer;
  • climatic conditions of the building location;
  • efficiency of the existing heating system;
  • current energy tariffs.

Who is it for

  • Private home owners — to assess insulation feasibility
  • Builders and designers — for preliminary calculations
  • Students and teachers — for educational purposes
  • Building materials sellers — for customer consulting

Accuracy and reliability of results

Calculation results are indicative, their reliability depends on accuracy of your input data.

How to use

🏠
Step 1: Basic Parameters

Enter the external wall area, desired indoor temperature, heating system efficiency, and energy tariff. Each field has a hint — click 'ℹ️ Instructions' for detailed explanations.

🧱
Step 2: Wall Structure

Describe your wall layers — select a material from the list or enter manually, specify thickness and thermal conductivity. You can add multiple layers.

🌡️
Step 3: Climate Data

Find your city using the search — the system will automatically load average temperatures and heating season duration. Or enter data manually.

📦
Step 4: Insulation Parameters

Select insulation type from the list or enter custom parameters. Specify costs for material, delivery, installation, and finishing.

📊
📊 Results

After completing all steps, click 'Calculate' — you'll get a comparison table of different insulation thicknesses with payback charts. Below the table you'll find tips on interpreting the results.

💡 Each step has an 'ℹ️ Instructions' button with detailed explanations and example values.
