Fiberglass Compound Base Mat and Fiberglass Mesh are pivotal for various applications within the construction and waterproofing industries. Even so, many professionals tend to confuse or use these two materials interchangeably because of their lack of understanding of the unique structures, properties or applications of each material. This article explains the differences that matter as far as manufacturers and contractors deciding different reinforcement materials is concerned.
1. Material Structure
-
Fiberglass Compound Base Mat is a composite material created through bonding fiberglass mesh with layers of polyester or other non- woven fabrics. The mat is flat, absorbent, and has good affinity to bond with bitumen making it suitable in waterproof membranes.
-
Fiberglass Mesh, on the other hand, is a woven fabric that manufacturers make from fiberglass yarns. It features an open grid structure, and producers usually coat it with an alkali-resistant treatment to enhance durability in cement-based applications.
2. Mechanical Properties
-
Compound Base Mat offers excellent dimensional stability and tensile strength in both longitudinal and transverse directions. It is more flexible and works well in the hot-melt processes used in membrane production.
-
Fiberglass Mesh has high tensile strength mainly in the warp (longitudinal) direction. It is less flexible and may break under folding or repeated bending if not coated properly.
3. Applications
-
Fiberglass Compound Base Mat is primarily used as the reinforcement core in bitumen-based waterproofing membranes, including SBS and APP modified membranes. Its strong bonding ability with bitumen ensures durability and waterproofing efficiency.
-
Fiberglass Mesh is mainly used in wall reinforcement systems, EIFS (external insulation finishing systems), and as anti-crack support in waterproof coatings. It is applied onsite and enhances tensile strength and crack resistance.
4. Surface Appearance and Weight
-
Compound Base Mat is usually smoother and thicker, with a weight ranging from 110g/m² to 260g/m² or more.
-
Fiberglass Mesh comes in various mesh sizes (e.g., 4×4, 5×5, 8×8, 9×9), and typically weighs between 60g/m² and 160g/m².
5. Summary
| Feature | Fiberglass Compound Base Mat | Fiberglass Mesh |
|---|---|---|
| Structure | Fiberglass + Nonwoven (Composite) | Woven fiberglass mesh |
| Flexibility | High | Moderate |
| Bitumen Compatibility | Excellent | Low |
| Common Use | Bitumen waterproofing membrane | Wall and coating reinforcement |
| Weight | Heavier | Lighter |
| Appearance | Flat and dense | Open grid |
Conclusion:
While both materials use fiberglass as their base, their design and functionality differ significantly. Manufacturers engineer Fiberglass Compound Base Mat for waterproof membrane production in factories, whereas construction teams prefer Fiberglass Mesh for on-site reinforcement in wall systems and coating applications. Selecting the right material ensures better performance, cost-efficiency, and durability in construction projects.
