Wholesale Price Synthetic Roofing Underlayment - Synthetic roof liner – JiBao

For decades, the use of felt as a waterproof liner seems to be the only choice. Of course, everything has two sides, and felt has its own shortcomings that are difficult to make up for. With the development of technology, synthetic liners came into being and became a qualified substitute for traditional felt liners. Compared with traditional felt materials, it has significant advantages.

Jibao’s products are recognized as excellent liners. Their function is the same as that of traditional felt pads, but they are better, can more effectively isolate moisture, and have a longer lifespan. Installing them under the shingles on the roof is the second line of defense for the house. If the wind comes, the shingles may be destroyed, and they can be used as a waterproof barrier to protect the roof. Synthetic liner has high tensile strength and can effectively prevent tearing.
Anti-ultraviolet rays, longer service life

With cushions made of traditional felt or organic materials, the cushion may crack over time. According to the statistics of the National Association of Certified Home Inspectors, when these traditional materials are exposed to high temperature and ultraviolet rays, the organic compounds begin to degrade and the cushion becomes more fragile.

This product is made of inorganic engineering materials, and its product characteristics are not easy to change under any circumstances, so the synthetic liner has a longer service life. This kind of high-quality synthetic roof liner will not bend, warp or crack over time like organic felt, and the surface UV coating allows continuous exposure to the sun for 60 days when the roof is installed. Because of its high heat resistance, even if it is installed on a slate or metal roof, there is no concern.
Provide a safer surface for steep slope installation

Regardless of the slope, walking on the roof is dangerous, but for sloped roofs with large slope angles, synthetic padding provides a non-slip surface, making it easier to walk on sloped roofs. In addition, its weight is much lighter than cushions made of traditional materials, which reduces the pressure on the roof and is easy to transport.

Tear resistance helps prevent waste.

Traditional liners have lower tear resistance, which makes them more susceptible to accidental damage during installation than synthetic materials, increasing construction difficulty and cost, and also causing additional waste. You need to pay special attention even when walking on the roof. This product does not have this concern.
