Linen Felt Bands

Linen caulking is an excellent choice for sealing window and door frames. Linen fiber is a natural material with unique insulating properties, making it ideal for both temperature and sound insulation.

In the past, houses were generally poorly insulated but well-ventilated. Modern houses are usually better insulated but often have poorer indoor air quality. By insulating with felt strips, you get the best of both worlds—higher energy efficiency while allowing moisture to be transported through wall and roof structures.
