Building Paper Grade A1F - 25m Roll
Building Paper Grade A1F is a multi-use adaptable building product. It is manufactured from traditional reinforced wet-strength kraft paper which has been laminated together using bitumen. A polymer reinforcement scrim runs throughout the bitumen core of the material. It meets the highest standard of BS 1521 materials, grade A1F, suitable for permanent building applications.
Building Paper Grade A1F is laminated with a bitumen core. It is used as a waterproofing/weatherproofing layer in building construction, as a vapour-check membrane, and for temporary protection and separation where a tough, water-resistant material is needed.
Fixing/Sitework
Store rolls before use on end on a clean, dry surface protected from the weather. Material should not be unrolled if the temperature is below 5°C as the adhesive will become brittle and may crack. Depending on application, Building Paper should be laid over flat surfaces or fixed to studwork, formwork or similar. It may be stapled, nailed or fixed with self-adhesive tapes.
Building Paper can be folded, and cut easily using a knife or scissors. The bitumen adhesive will tend to seal around nails or other fixings to maintain a water and water vapour-tight construction. Edges should be overlapped by at least 100mm, and if the installation is intended to be waterproof or water vapour-tight the seams should be welted or taped using a durable self-adhesive polymer tape.
