Rytons A1 Fire-rated Metal Rytweep

Cavity weep hole ducts are a pre-formed component long established as an effective method of allowing the cavity to drain freely without obstruction. Quick and easy to position as work proceeds and virtually invisible within the mortar joint so not to detract from the appearance of the brickwork.

The tapered design restricts the entry of wind-driven rain to prevent staining, meeting NHBC Standards and maintaining the aesthetic appearance of the building.

Installation of Rytons A1® Fire-rated Metal Rytweep®

Installation is fast and easy as work proceeds with the Rytweep® replacing a vertical mortar joint. Ensure the tapered end with the circular outlet is facing the outside and is flush with the external face.  Position the bottom of the Rytweep® on the mortar bed against the brick/block. Position the next brick alongside the installed Rytweep® and mortar in until only the small weep outlet is visible (ensuring the outlet does not become blocked). Space every fourth brick to drain cavities above and below the damp proof course, and above lintels and cavity trays. At least two weep holes should be provided over an opening, i.e. lintel.
