FAQs
What is the primary function of the telescopic design?
It allows the unit to extend up to 70mm, providing flexibility for different wall thicknesses and the projection of exterior finishes.
Can this be used in a rendered wall?
Yes, it is specifically designed to accommodate masonry and rendered wall applications.
Does it come in other colors?
Yes, it is available in clear, grey, beige, and black to match different brickwork aesthetics.
Why is there a protective cap?
The cap prevents wet mortar from falling into and clogging the weep during the bricklaying process.
What is the airflow capacity?
The unit provides 60mm2 of clear airflow, which is designed to maintain cavity health.
Is the grille insect-proof?
Yes, the outlet grille is designed to prevent insects from entering the cavity wall system.
Troubleshooting
Airflow seems blocked after installation
Check if the protective cap was removed, or inspect the grille for external debris.
The unit is too short for the current wall thickness
Verify the wall thickness is within the 70mm telescopic adjustment range; consider using a different mounting configuration if the wall exceeds this depth.
Pros and Cons
Pros

Setup, Compatibility & Care
For optimal results, insert the telescopic weep during the bricklaying phase, ensuring the body is correctly positioned within the cavity. Keep the protective mortar cap installed throughout the construction process to prevent mortar droppings from obstructing the airflow path. Once all brickwork and rendering are complete, remove the protective cap to expose the insect-resistant grille. The unit is compatible with standard brick dimensions and can be used in both new builds and renovation projects where cavity walls are being addressed. No specific cleaning is required post-installation, though an occasional visual check ensures the grille remains clear of external debris.
