PROVEN HISTORY OF HOME PROTECTION
HAL Felt has been the choice underlayment for home protection since 1974, with decades of proven performance in the field. With the home owner in mind, we exceed all applicable industry standards.
HAL Felt is designed and manufactured to allow the transmission of moisture vapour, allowing the roof deck to breathe, while keeping bulk water from shingle leaks out. This helps prevent the rotting of wood decks, which can be caused by non-permeable synthetic products, and helps roofing materials last longer.
HAL Felt is manufactured to have the best walking surface of any roofing felt on the market.
MADE WITH THE CANADIAN ENVIRONMENT IN MIND
HAL Felt is made in Canada from locally sourced materials that have both pre-consumer and post-consumer wood and paper recycled material, garnering LEED (Leadership in Energy and Environmental Design) points where applicable.
HAL Felt is pre-conditioned to lay flat and remain stable during and after installation. Our heavy weight reinforcements greatly increase tensile strength and prevent tearing during installation.
HAL Felt is used beneath shingles, shakes or tiles as a secondary protective layer between the roof deck and the finished roofing. This secondary layer protects against wind-blown moisture which may occasionally penetrate past the outer roofing material.
