Insulation Optimizer
R-value & payback. This multi-solver chains 2 solvers into a single guided workflow — run each step in order and carry the result forward.

Heat flows through a wall like current through resistors in series. Each layer's thermal resistance is its thickness over its conductivity; adding them gives the total R-value, and the heat flux is the temperature difference divided by it. Insulation, with very low conductivity, dominates the R-value — the steep temperature drop shows where it does its work.

Your carbon footprint is the sum of the greenhouse gases your lifestyle emits each year. The big levers are usually flying, driving, home energy, and diet. The global average is about 4.7 tonnes per person, but a livable-planet target is closer to 2 tonnes. Estimates use typical emission factors and will vary by region.

Frequently asked questions
- What is the Insulation Optimizer multi-solver?
- Insulation Optimizer is a guided workflow that chains 2 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
- Is it free to use?
- Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
