While insulation are best placed during construction, your
existing granny flat might not have
enough to keep the entire structure energy-efficient. Because a well-insulated building
means great savings on energy bills, it’s never too late to retrofit them if
you think you need more than what you already have in your flat.

When it comes to insulation, cavity brick walls pose a great
challenge because their high thermal mass makes the interior space too warm
after prolonged exposure to the outside heat. And during winter, bricks quickly
absorb heat from inside the flat, rendering the interior space too cold.
