Neutras-4 low thermal conductivity wall ties

Neutras-4 light duty wall ties are engineered for superior thermal efficiency and structural performance. Their low thermal conductivity allows them to be excluded from U-value calculations under EN ISO 6946, making them an ideal solution for meeting updated energy efficiency regulations. Designed for domestic dwellings with cavity widths up to 175mm and a maximum building height of 10m, Neutras-4 ties provide long-term durability and reliable moisture control through an innovative constant-drip spiral design.
