Attic insulation does a lot more than just keep your home warm – it plays a quiet but powerful role in comfort, energy efficiency, and even the health of your home. Below, we’ll go over a few lesser-known facts about attic insulation that property owners often overlook.
- Insulation works year-round. While it’s essential for keeping heat in during cold winters, attic insulation also helps keep excess heat out during the warmer months, which helps reduce strain on your cooling system.
- R-value isn’t one-size-fits-all. The effectiveness of insulation is measured in R-value, but the “right” level will depend on the climate you live in. Homes in colder regions generally benefit from higher R-values to maintain efficiency.
- Air sealing matters just as much. Even the best attic insulation won’t perform well if the area has air leaks. Gaps around vents, wiring, and hatches can let outside air transfer in, impacting the overall effectiveness.
- Moisture is a major hidden threat. Issues like poor ventilation or insulation can lead to condensation buildup, which can then cause mould growth or even structural damage over time.
- Insulation can settle or degrade. Older materials, especially loose-fill insulation, may compress or shift, which reduces effectiveness. It’s not always obvious, so professional assessment is key.
- Ice dams are often attic insulation–related. Uneven attic temperatures can cause snow to melt and then refreeze along the roof’s edge, which creates ice dams.
