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 when installed at a standard 2.5 ties/m2 spacing and is therefore suitable for internal separating (party) walls of new-build attached dwellings with cavities from 50mm to 150mm.
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.
Length: 250mm for 101-125mm cavities
