Why R2.7 Wall Insulation Is Perfect for Adelaide Homes

Looking to improve energy efficiency in your new build or renovation project? R2.7 wall insulation is one of the most effective options available — especially in Adelaide, where seasonal temperature shifts can be extreme. At Adelaide Insulation Centre, we stock high-performance Earthwool R2.7 batts designed for 90mm timber or steel-framed walls.

What Makes R2.7 Insulation Special?

The R-value measures thermal resistance — the higher the number, the better the performance. R2.7 wall batts provide better insulation than standard R2.0 or R2.5 options, making them ideal for homeowners who want superior comfort and energy savings year-round.
