Manthorpe G630 Felt Lap Vents

These Manthorpe Felt Lap Vents will help stop condensation in the loft.

Attic or loft condensation is normally spotted either in the winter months, or after installing new loft insulation. All homes generate moisture from everyday activities like cooking and showering. When this moisture condenses in a cold loft it can eventually lead to costly problems like rotten roof timber.

Condensation in the loft is usually caused by inadequate loft ventilation. This can often be remedied quickly and easily if your loft has traditional lapped membrane or roofing felt behind the tiles. Lap vents are fitted inside the loft by simply clipping individual vents onto the edges of the felt or membrane close to the eaves.

Each felt lap vent creates an air gap delivering up to 3000mm2/m of ventilating airflow. When combined with existing roof space ventilation, fitting evenly spaced lap vents on both sides of the loft will fix most loft condensation problems.

Features & benefits:

  •     Improved ventilation eliminates most loft condensation problems.
  •     Simply slide each tapered felt lap vent between the felt or membrane laps close to the eaves.
  •     Quick and easy to fit inside the loft – no tools needed.
  •     Built-in clips hold the vent secure – even on damaged roof felt edges.
  •     Suitable for lapped membrane or roofing felt with joist centres from 400mm to 600mm.
  •     Manufacture: Polypropylene.
  •     Brand: Manthorpe.
  •     Product Code: G630.
  •     Size: 275mm x 193mm.
