Application

Light-duty wall ties (type 4) are suitable for use in domestic dwellings. Suitable for buildings with a maximum height of 10 m and cavity widths of 50–150 mm.
General-purpose wall ties (type 2) are suitable for use in small commercial buildings and domestic dwellings. Suitable for buildings with a maximum height of 15 m and cavity widths of 50–125 and 125–150 mm.
Heavy-duty wall ties (type 1) are suitable for most buildings in the UK of any height, with cavities up to 150 mm.

Description

For securing two leaves of a cavity wall to each other, allowing them to act as one structurally.

Features and benefits:

Will adequately resist thermal transmittance.
Constant drip feature to prevent moisture travelling across the cavity.
Available with a dedicated clip to secure insulation (usually in sheet form) within the cavity.
Tested as Type B (sound).
Tested Types 4, 2, & 1 to BS EN 845-1.
BBA certified 17/5462.
