Earthwool R4.0HD Sound Shield Wall Insulation Batts
Improve your home’s energy efficiency with Earthwool R4.0HD Sound Shield Wall Insulation Batts, an advanced solution designed to enhance thermal comfort, reduce energy costs, and minimise noise. Whether you’re building a new home or upgrading existing walls, these batts provide a reliable and environmentally responsible insulation option.
Earthwool R4.0HD Sound Shield – Outstanding Thermal Performance
With an R-value of 4.0, Earthwool wall batts offer excellent thermal resistance. As a result, they help maintain a stable indoor climate throughout the year. During winter, they reduce heat loss, and in summer, they help keep the heat out. Therefore, your heating and cooling systems use less energy, which can significantly lower your power bills.
Softer, Safer, Smarter
Unlike traditional insulation, Earthwool batts are manufactured with ECOSE® Technology, which uses bio-based binders instead of harsh chemicals. Consequently, the batts feel softer to handle and are easier to install. In addition, they are low in dust, odourless, and contain no added formaldehyde—making them safer for your family and the environment.
Excellent Acoustic Control
Not only do these batts provide thermal insulation, but they also help minimise noise transfer. As a result, you’ll enjoy a quieter and more peaceful indoor environment. This makes them ideal for busy households, shared walls, or properties near high-traffic areas.
Versatile and Easy to Install
Earthwool R4.0HD Wall Batts are available in a range of sizes to suit standard wall cavities. Therefore, you can select the ideal fit for timber or steel framing, which simplifies installation and reduces waste. Each size is listed below as an individual product to make selection easy.
