R2.0 Wall Insulation

R2.0 Wall Insulation Sizes and Thickness

R2.0 wall insulation is available in different thicknesses and densities depending on the manufacturer and product. Standard R2.0 thermal wall batts are commonly around 90mm thick, while selected higher-density R2.0 products can provide the same thermal resistance in a thinner batt while also offering additional acoustic performance. Before ordering, check the thickness of the individual product against the available wall-cavity depth. Product specifications vary between brands, so compare the stated R-value, batt thickness, width and pack coverage rather than selecting insulation by thickness alone.

430mm vs 580mm R2.0 Wall Batts

Common R2.0 wall insulation widths include approximately 430mm and 580mm, designed to suit common wall-framing configurations. Some products are available in slightly different widths, so always measure the actual space between the wall studs and check the individual product dimensions before ordering. Correct fit is important for thermal performance. Wall insulation should be installed neatly within the framing without unnecessary gaps or compression, following the manufacturer's installation requirements.

Thermal vs Acoustic R2.0 Wall Insulation

Our R2.0 range includes standard thermal wall insulation as well as higher-density acoustic products. Standard R2.0 thermal batts are suitable for projects where reducing heat transfer through the wall is the primary requirement. Higher-density R2.0 wall insulation can also help reduce sound transfer when installed in suitable wall systems, making it useful for bedrooms, home offices, media rooms and internal walls where additional acoustic performance is required. When comparing thermal and acoustic R2.0 products, consider the batt density, thickness, dimensions, material and pack coverage as well as the requirements of the wall system.

R2.0 Wall Insulation Brands

No Gap Insulation supplies R2.0 wall insulation from brands including Knauf Earthwool, Bradford, Pink Batts, SCG and Polyester Solutions. Our range includes glasswool and polyester insulation, with standard thermal and higher-density acoustic options available in different batt dimensions and pack sizes.

Benefits of R2.0 Insulation

Thermal performance — Helps reduce heat transfer through wall cavities and supports improved indoor comfort throughout the year. Acoustic options — Selected higher-density R2.0 products can also help reduce sound transfer between rooms when installed in suitable wall systems. Multiple material options — Choose from glasswool and polyester wall insulation depending on your project requirements. Different sizes and densities — Compare standard and higher-density R2.0 products in different thicknesses, widths and pack sizes. Residential and commercial applications — R2.0 wall insulation is available for a range of new-build, renovation and selected commercial wall applications. Residential and commercial applications — R2.0 wall insulation is available for a range of new-build, renovation and selected commercial wall applications.

Choosing the Right R2.0 Wall Insulation

Start by confirming that R2.0 is the appropriate R-value for your project. Then check the wall stud spacing, cavity depth and total wall area that needs to be insulated. Compare the batt width and thickness with the available framing space, then check the square-metre coverage of each pack to estimate the quantity required. If acoustic performance is also important, compare the higher-density R2.0 options with standard thermal wall batts before ordering. Need more information before choosing?
