💨 Breathe new life into your roof — stop condensation before it starts!
The Manthorpe G630 Felt Lap Ventilator is a retrofit solution designed to increase ventilation in roof spaces with lapped felt or membrane construction. Each unit provides 3,000mm² of airflow, fits rafter spacings between 400mm and 600mm, and installs easily with a tapered lead-in and felt clips. Ideal for homes with added loft insulation, it helps reduce condensation buildup by enhancing airflow through the felt laps, promoting healthier attic environments.
