Why Older Canberra Homes Need Wall Insulation

The Problem with Older Homes

Many Canberra homes built before the 1990s were constructed with little or no wall insulation. These properties often lose heat rapidly in winter and absorb it in summer. The result is rooms that feel cold, hot, or drafty—and energy bills that are unnecessarily high.

How Wall Insulation Helps

Insulating the walls creates a thermal and acoustic barrier. It helps regulate indoor temperatures and also dampens outside noise—perfect if you live on a busy road or near a school. Proper wall insulation can make a noticeable difference in daily comfort levels.

Retrofitting Without the Mess

One of the most common concerns from homeowners is the potential disruption involved in insulating existing walls. Fortunately, modern techniques allow retrofit wall insulation to be installed with minimal mess. Small holes are drilled between the wall studs, and insulation is pumped in. The holes are then patched and repainted.

Suitable for Most Homes

Whether your home has weatherboard, brick veneer, or even double brick, there’s usually a solution available. The key is to have the walls assessed by professionals to determine the best approach.

Energy Efficiency Boost

Wall insulation can cut heating and cooling costs by up to 25%, especially when combined with ceiling and underfloor insulation. It also adds value to your home by increasing its energy efficiency rating—an important factor for resale or rental.
