Two Types of Asphalt Shingles:
Asphalt shingles come in two types: Organic and Fiberglass:
- Organic shingles are based on paper (waste paper) saturated with asphalt to make it waterproof, with coatings of adhesive salt and ceramic granules embedded on top. While organic shingles are more durable than fiberglass ones. They are less environmentally-friendly due to their high asphalt (oil based) content.
- Fiberglass shingles offer excellent fire protection. Today, fiberglass shingles are more commonly used and are slowly, but surely, replacing the organic shingles. Fiberglass shingles are made with a base layer of glass fiber reinforcing mat. This mat is coated with asphalt, which contains mineral fillers and makes the shingle waterproof.
