It is vital to consider their material makeup as well as their functional attributes and performance metrics when selecting between a compound base mat and a polyester mat. We outline the fundamental differences below to better guide your decisions.
Material Composition
Compound Base Mat
It is vital to consider their material makeup as well as their functional attributes and performance metrics when selecting between a compound base mat and a polyester mat. We outline the fundamental differences below to better guide your decisions.
Polyester Mat
On the other hand, the polyester mat is made almost entirely from polyester fibers. These fibers are highly regarded for their strength and tough longitudinal strength which makes them ideal for several use cases.
Performance Characteristics
Compound Base Mat
The compound base mat seamlessly integrates the thermal stabilization provided by fiberglass with the tensile strength of polyester fibers. It showcases the best balance between performance and cost, being highly dimensionally stable while resisting tears. This attribute also makes it ideal for severely harsh environments.
Polyester Mat
The polyester mat stands out for its high elasticity and tensile strength, allowing it to handle significant deformation. However, its dimensional stability is slightly weaker, and it may shrink under high temperatures.
Waterproofing Performance
Compound Base Mat
The compound base mat ensures superior stability in the waterproof layer, making it an excellent choice for long-term resistance to aging and cracking. Its performance remains consistent even under challenging conditions.
Polyester Mat
While the polyester mat also offers excellent waterproofing, it may not perform as steadily as the compound base mat in environments with extreme temperature fluctuations.
Application Scenarios
Compound Base Mat
This mat is ideal for projects with high waterproofing demands and structural support requirements. Common applications include bridges, tunnels, and large-scale roofing projects.
Polyester Mat
The polyester mat is well-suited for general roofing, basements, bathrooms, and other environments where high tensile strength is essential. It is also easier to install and more cost-effective.
Conclusion
If your project requires a balance between stability and tensile strength, the compound base mat is the better choice. On the other hand, if ease of installation and cost efficiency are your priorities, the polyester mat can meet most waterproofing needs.
