About: HAL Building Paper is a breathable weather resistant membrane (WRB) made of high quality asphalt saturated kraft paper. It is designed to shed water and restrict moisture from penetrating, while allowing the passage of water vapour by diffusion through the membrane to the exterior. HAL 20 Minute, 30 Minute, and 60 Minute Building Paper meet and exceed all industry standards.
Uses: Building Paper is used in a single ply or double ply application on outside walls of wood frame buildings, and can be applied beneath wood siding, stucco, brick, aluminium, vinyl, or any other type of siding.
Proven History of Home Protection: HAL Building Paper has been the choice weather resistant membrane 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.
Made With the Environment in Mind: HAL Building Paper 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.
Installation: When starting with a 20 starter course HAL Building Paper makes it easy to install a 2 ply system in one application. A two ply system allows the outside layer to protect the inside layer from weather forces prior to the exterior cladding being installed.
