How to choose high-quality asphalt shingle - Fiberglass mat?

High-quality asphalt shingles are inseparable from high-quality raw materials. The substrate material is the heart of asphalt shingles. There are three types of base materials in the market: composite tires , polyester tires , and glass fiber tires .

『1』The asphalt shingles using Composite tires as base material, which surface will obviously have a layer of grids. The shingles are with poor temperature resistance, as well upper and bottom layers of the shingles are easy to tear, now they are banned to use.

『2』The asphalt shingles using Polyester tires as base material, which are easily weathered and rotted under high temperature conditions, and have poor waterproof performance, so they are not recommended to use.

『3』The asphalt shingles using glass fiber tire as base material, which are applicable to various climatic conditions. It can be used in places with a low temperature of minus 35 degrees and a high temperature of 90 degrees without deformation and damage. It has excellent waterproof performance and longtime lifespan (national standard 95g/ ㎡), Jingda New West Lake brand asphalt shingles use 110g/㎡ high-quality glass fiber tire as the base materials.

There are methods to distinguish different shingle types such as by measuring the thickness and check the quality.  Generally, the thickness of glass fiber asphalt shingles are controlled between 2.6mm-2.7mm per layer according to the national standard , which is thinner than the other two types of substrates. Also lighter.
