Suitable for refurbishment applications, the Manthorpe Felt Lap Vent is designed to increase the amount of ventilation in existing roof spaces. Though usually fitted retrospectively to properties with additional loft insulation installed, the felt lap vent will help combat the problem of condensation build-up in any roof space with a lapped felt/membrane construction.
Following installation, each unit provides 3,000mm² per metre of free airflow into the batten void. This helps prevent the risk of condensation built up caused by the additional insulation.
Please note:
