Without proper ventilation, moisture can accumulate, leading to dampness and structural damage.

Why Choose Type RAV-FL Roof Abutment Ventilators?
- Optimal Ventilation: Designed for effective roof abutment and flat roof ventilation.

- Easy Installation: The preformed units are simple to install, reducing labour time.
Solve Dampness Issues with Type X Remedial Cavity Tray
When a pitched roof extension or conservatory is built against an existing cavity wall, relying solely on flashing is insufficient to prevent moisture ingress. The Type X Remedial Cavity Tray offers an effective damp-proofing solution by preventing water from permeating downward. Installation involves removing sections of masonry above the roofline, inserting the tray, and ensuring proper alignment for continuous moisture protection.
