In construction, it’s easy to underestimate the role of sealants—until one fails.
Cracked joints, air leaks, and water intrusion can all result from underperforming sealants. That’s why choosing the right sealant is about more than cost or color. It’s about durability, movement capability, and long-term reliability under real-world conditions.
At Manning Materials, we trust Tremco to deliver that reliability. Here’s a closer look at what sets Tremco’s high-performance sealants apart—and why their rigorous testing matters for your next build.
Why Testing Matters in Sealant Performance
Sealants are a small but critical part of the building envelope. If they fail, the consequences can include:
- Moisture damage and mold
- Energy loss due to air leakage
- Costly repairs or premature replacement
To avoid these outcomes, Tremco subjects their sealants to comprehensive testing to verify they perform under a range of stresses and environments. This includes lab testing, in-field validation, and real-world simulations.
Key Performance Factors: What Makes a Sealant “High-Performance”?
- Adhesion and Substrate Compatibility
A high-performance sealant must bond to a wide range of materials, including glass, concrete, metal, wood, and more. Tremco tests its sealants on common and challenging substrates to ensure consistent adhesion without priming (unless specified).
- Movement Capability
Buildings expand and contract. Tremco sealants are designed to move with them. Products like Dymonic® 100 and Spectrem® 1 offer excellent movement ratings (often ±50% or higher) to prevent cracking or delamination.
- Weather Resistance
Rain, UV rays, temperature swings—Tremco sealants are formulated to withstand them all. Accelerated weathering tests simulate years of outdoor exposure to ensure longevity in real-world climates.
- ASTM & ISO Compliance
Tremco sealants are tested to meet or exceed industry standards, including:
-
- ASTM C920 – Standard for elastomeric joint sealants
- ASTM C1248 – Stain and color change resistance
- ISO 11600 – International standards for building sealants
These certifications give specifiers confidence that Tremco products are performance-tested, code-compliant, and project-ready.
- Cure Speed and Tooling
In fast-paced construction, cure speed and ease of application matter. Tremco engineers products for smooth application, even in extreme temperatures, with fast skin-over times to prevent job delays.
What Sets Tremco Apart?
Tremco doesn’t just test for the lab—they test for the real world.
Many of their sealants are part of fully integrated building envelope systems, working in tandem with air barriers, waterproofing membranes, and glazing components. This systems-based approach ensures:
- Seamless compatibility
- Fewer call-backs
- Better long-term performance
And when challenges arise, Tremco backs its products with technical support, field service, and resources for architects, specifiers, and contractors.
