Why insulate your walls?

This thermal camera image of a living room shows the ceiling is warm due to good insulation, while uninsulated walls allow heat to escape.

You can have a well-insulated ceiling…
…but if your walls aren’t insulated, heat will still escape.

If your walls are uninsulated, blown insulation is a retrofit solution that helps you achieve a complete thermal envelope without removing wall linings, avoiding the added cost of re-gibbing, plastering, and painting.
