Canberra’s climate is unique. Winters regularly drop below zero overnight, while summers can bring intense heat. Without the right insulation, homes can feel freezing in winter, hot in summer, and expensive to heat or cool.
That’s where R-values come in. An R-value measures how well insulation resists heat flow. The higher the number, the better it keeps heat inside during winter and outside during summer.
For most Canberra homes, ceiling insulation delivers the biggest improvement in comfort and energy efficiency. Because heat rises, a poorly insulated roof can allow a significant amount of warmth to escape during winter. For this reason, we typically recommend R5.0 or higher ceiling insulation for homes across the ACT.
Underfloor insulation can also play an important role in improving comfort, particularly in homes with raised timber floors. Installing insulation beneath the floor can reduce drafts, help stabilise indoor temperatures, and make rooms feel noticeably warmer in winter.
Of course, choosing the right product is only part of the equation. Installation quality is just as important as the R-value itself. Gaps, compression or poor fitting around services can reduce the effectiveness of insulation. That’s why our work is carried out by Energy Efficiency Council (EEC)-certified installers, ensuring best-practice installation every time.
