Contact & Support

The fastest way to reach us is hello@smartinsulationcalculator.com. We answer most messages within two business days.

If you're reporting a calculator problem, include the page name, the numbers you entered and the result you expected. That's usually enough for us to reproduce it the same day.

Prices and code-recommended R-values move. If you have a supplier quote or a code reference that contradicts something on this site, send it over — we update the underlying data files rather than patching individual pages, so a good correction improves every page at once.

We can't quote your job, size a mechanical system, act as your energy auditor, or approve anything for permit. For work that has to satisfy an inspector, use a licensed contractor or a certified energy rater.
