Description

💨 Breathe New Life Into Your Roof — Stop Condensation Before It Starts!

MAXIMIZE ROOF BREATHABILITY - Each vent delivers 3,000mm² of free airflow to combat condensation effectively.
QUICK SECURE INSTALLATION - Tapered lead-in and 3 felt clips ensure a snug fit—even on degraded felt edges.
VERSATILE FIT FOR MODERN ROOFS - Designed to fit joist spacings from 400mm to 600mm, perfect for most loft refurbishments.
CROSS FLOW VENTILATION STRATEGY - Install on both sides near eaves for optimal airflow and healthier attic spaces.
RETROFIT READY FOR INSULATED LOFTS - Ideal for adding ventilation after loft insulation upgrades, preventing costly moisture damage.

The Manthorpe Pack 20 G630 Felt Lap Vent Stops are a retrofit ventilation solution designed to increase airflow in roof spaces with lapped felt or membrane construction. Each vent provides 3,000mm² of free airflow and fits joist centres between 400mm and 600mm. Easy to install with a tapered lead-in and secure felt clips, these vents help prevent condensation buildup caused by additional loft insulation. While not a standalone ventilation system, they are essential for improving attic airflow and maintaining roof integrity when upgrading insulation.
