SKU
RD030109

The Manthorpe Felt Lap Vent is a refurbishment product designed to increase the amount of ventilation into existing roof spaces. 

  • Can reduce the risk of condensation where insulation has already been fitted. 
  • Can be fitted at joist centres ranging from 400mm to 600mm.
  • 3,000mm²/m airflow.
  • Easy to fit, the tapered lead in helps to slot the product between the felt laps.
  • The 3 felt clips help secure the product in place even if the edge of the felt is degraded.
