Energylite® 47.5 kg/m³ insulation batts are medium-high density glasswool products used in commercial and industrial applications requiring enhanced thermal performance, acoustic control, and rigidity up to 350 °C.
Est. Delivery: 20 July – 21 July
Energylite® 47.5 kg/m³ glasswool batts are manufactured from high-quality inorganic glass fibres and supplied in pre-cut batt form for installation between framing, partitions, and structural cavities. The increased density compared to lower-grade batts provides better shape retention, improved sound absorption, and more stable long-term performance in demanding environments.
The batts are supplied per pack, with coverage determined by batt size, thickness, and pack quantity. When correctly installed, Energylite batts maintain consistent thermal and acoustic performance without sagging or settling.
Energylite glasswool batts fall within the mineral wool insulation category and are specifically classified as glasswool insulation, offering a balance between performance, flexibility, and ease of handling.
These products are intended for internal insulation applications only and are not suitable for exposed or weather-facing installations.
