Earthwool R2.0 HD Wall Insulation

Earthwool R2.0 HD Wall Insulation

Earthwool R2.0 HD wall insulation batts help reduce heat transfer through suitable wall constructions. These glasswool batts have a nominal thickness of 75mm and come in 430mm and 580mm widths, with twenty batts in each pack.

Choosing Your Earthwool R2.0 HD Pack

First, measure the clear spaces between your wall framing and check the available cavity depth. Then compare those measurements with the batt dimensions below. The selected width should suit the actual space and the manufacturer’s installation requirements.

The 430mm and 580mm options listed here are timber-frame sizes. If your project uses steel framing, confirm the specified dimensions before purchasing. Do not assume that the same batt width suits both framing systems.

Pack Sizes and Coverage

The 430mm pack contains approximately 10.0m² of insulation material. For the wider 580mm option, the actual batt area is approximately 13.5m² per pack. Check the Specifications tab for the pack prices and coverage figures used on this page.

Actual batt area and coverage allowing for framing are different measurements. When comparing prices per square metre, use the same basis for each product. Also allow for your wall layout, openings and cutting when estimating quantities.

Planning Your Wall Insulation

Choose the R-value to suit your building design and project requirements. R2.0 describes the material’s thermal resistance; the performance of the completed wall also depends on its other components and how the insulation is installed.

Before work begins, check that the cavity is suitable and follow the manufacturer’s instructions around services and fittings. Install the batts with a consistent fit and sufficient space to maintain their specified thickness.
