This 4-layer synthetic roof liner film is made of a non-woven polypropylene scribe line laminated on the exposed side of a woven polypropylene scribe line coated on both sides. The polished surface is specially designed to reduce slippage. The film has high resistance to tearing and can be exposed for up to 6 months. It can be installed on various types of sloped roof materials; asphalt shingles, metal roofs, wood vibration, synthetic or slab tiles.

Perfect Synthetic Roof Underlayment with Fusion Back Coating Technology is strong, durable and repels water. Its also light, easy to install and contributes to safe working conditions. In addition to its unparalleled quality and performance, offers the following features and benefits.

10 Square Rolls Provide More Coverage Compared To Felt Paper
Lightweight 20 lb roll is easy to install and features clearly marked fastening guidesDual-surface slip resistance: fusion back coating technology paired with a non-woven surface provides excellent walking conditions during shingle application even on steeply pitched roofs.

Advanced Engineering
Hebei Jibao Roofing Underlayment with its advanced engineering is highly recommended for mechanically attached, coated woven synthetic roofing underlayment for sloped roofs.Hebei Jibao is specifically manufactured to replace the #15 Felt and #30 Felt.

Cooler Working Surface
Hebei Jibao unique gray top layer which provides for a cooler working surface can be used under primary roofing materials to replace #15 Felt and #30 Felt. Hebei Jibao high traction walking surface permits easier steep slope walk-ability, even during high condensation or moisture on the surface.

High anti skid bottom
Hebei Jibao anti-skid bottom surface made with advanced polymers helps keep the underlayment intact and prevents the fabric from tearing while it is being fastened avoiding any leakages through the underlayment layer.
