Neutras-2 low thermal conductivity wall ties

The Neutras-2 Low Thermal Conductivity Wall Ties are high-performance, general-purpose cavity wall ties engineered for superior structural integrity and exceptional thermal efficiency. Designed to meet the latest building regulations, these wall ties are ideal for domestic dwellings and small commercial buildings up to 15m in height with cavity widths up to 300mm. With low thermal conductivity, they can be excluded from U-value calculations under EN ISO 6946—making them a credible choice for energy-efficient construction. BBA Approved (Agrément Certificate: 17/5462), Neutras-2 ties offer long-term durability, fire resistance, and effective moisture control, all while simplifying compliance and installation.
