Our Felt Lap Vents are a refurbishment product designed to increase the amount of ventilation into existing roof spaces. 
 
Usually fitted retrospectively to properties with additional loft insulation recently installed, however the Felt Lap Vent will help to combat the problem of condensation build up in any roof space with a lapped felt/membrane construction.
 
These can also be used to increase airflow in the roof space to enable PIV systems to work effectively.
