The Staifix HRT4 is suitable for cavities from 50mm to 150mm and can be used in the construction of domestic houses up to 10 metres in height. Altitude and wind speed restrictions may apply.

Independent tests have proven the Staifix HRT4 has a measured dynamic stiffness of <4.8MN/m³ at a cavity of 50-100mm and 125-150mm and is therefore suitable for internal separating (party) walls of any height in new-build attached dwellings with these cavities.

The Staifix HRT4 is CE Marked and can be used in line with NHBC standards.

The HRT4 can be used with all approved robust details for cavity masonry separating walls, whether traditional or thin-joint blockwork. Use of these details eliminates the need for pre-completion sound testing.
