Full details
The Manthorpe G800 Continuous Soffit Ventilator is an essential component for roofers and homeowners looking to ensure consistent airflow in roof spaces.

It is a reliable, low-maintenance solution for most roof configurations, though installers must ensure their soffit boards fall within the 4mm to 12mm thickness range to ensure a secure fit.

Does this vent prevent insects from entering the loft?

Where exactly is the G800 mounted?

Troubleshooting
Soffit board does not fit into the mouth of the vent.
Verify the thickness of your soffit board; if it exceeds 12mm, the board will not fit into the G800 profile.
The vent strip appears loose after installation.
Ensure that the ventilator is fully seated against the back of the fascia and that all fixing points are securely fastened.
Pros and Cons
Pros
- Simple, intuitive installation process
- Effectively prevents insect entry
- Suitable for a wide range of soffit thicknesses
- Low-profile aesthetic for a clean roofline

Setup, Compatibility & Care
To install, position the G800 along the top edge of your fascia board and fix it securely using appropriate corrosion-resistant nails or screws. Ensure the soffit board, which should be between 4mm and 12mm thick, is fully inserted into the vent channel before fixing it to the wall/joist. No specialized tools are required beyond a standard hammer or drill and a saw for cutting the strip to the desired length. For care, simply perform a visual inspection during routine gutter cleaning to ensure no extreme buildup of debris has obscured the airflow slots.
