Insulation Principles

Insulation reduces heat flow and is often the highest-return upgrade in low-energy buildings.

Key Concepts

• —Heat transfer occurs through conduction, convection, and radiation.
• —Continuous insulation and air sealing work together.
• —Moisture control prevents insulation failure and mold growth.
• —Thermal bridges can undermine otherwise good wall systems.

Practical Guide

1. 1.Identify main heat-loss paths: roof, openings, floor edges, and drafts.
2. 2.Use available insulating materials such as straw, wool, or cellulose where appropriate.
3. 3.Seal uncontrolled air leaks before adding more heating capacity.
4. 4.Install vapor and drainage strategies compatible with local climate.
5. 5.Check interior comfort and condensation after upgrades to tune ventilation.
