  • All homes generate moisture from everyday activities like cooking, showering and drying clothes, this moisture condenses in the cold loft and leads to costly problems like rotten roof timber. Felt Lap Vents are the solution as these are designed to prevent condensation and moisture drops by improving ventilation and increasing the amount of fresh airflow in roof / attic / loft.
  • These can easily be installed from inside of roof / attic / loft, just slot between the felt laps. 5 clips secure the product in place by holding on to the edges of the felt. These should be fitted on evenly spaced distances, on both sides of the loft, close to the eaves.
