Construction sealants play a critical role in modern building systems. They prevent water infiltration, reduce air leakage, and block dust, noise, and other environmental factors. As a result, construction sealants help protect structural integrity, improve energy efficiency, and extend the lifespan of buildings.
Below are the most common building applications where construction sealants deliver long-term performance.
Weatherproofing Exterior Joints
First and foremost, sealants provide long-term weather protection for exterior joints and seams. InnoStar sealants offer excellent weatherability due to their near-zero solvent content, which eliminates shrinkage over time. In addition, these sealants accommodate joint movement, recover from thermal expansion stresses, and resist UV exposure. Together, these properties contribute to exceptional durability and extended service life in exterior applications.
Control Joints in Concrete and Masonry
Control joints help manage cracking in concrete and masonry surfaces. Sealants fill these joints to prevent water intrusion, which can weaken the structure over time. For this reason, builders commonly use construction sealants in control joints found in concrete floors, sidewalks, and driveways.
Expansion Joints for Structural Movement
Similarly, structures that experience expansion and contraction require flexible sealing solutions. Sealants applied to expansion joints allow movement while maintaining a watertight and airtight seal. You will often find these joints in bridges, highways, parking structures, and commercial buildings.
Glazing and Curtain Wall Applications
Sealants also play a vital role in glazing systems. They secure glass panels in windows and curtain walls while creating a weather-resistant barrier. By preventing air and water penetration, these sealants help maintain the building envelope and improve overall energy performance.
Roofing Applications
When it comes to roofing, performance standards matter. InnoStar construction sealants used in standing seam roofing meet or exceed MBMA and relevant ASTM specifications. Additionally, their low-VOC formulations can contribute toward LEED points in many building projects. For project-specific requirements, consulting an InnoStar representative ensures proper product selection.
Acoustic Sealing and Vibration Control
Beyond weather protection, construction sealants also support acoustic performance. InnoStar sealants feature excellent elasticity, which allows them to absorb vibration and reduce sound transmission between building components.
Airtightness and Energy Efficiency
To further improve building efficiency, construction sealants create continuous airtight barriers. InnoStar sealants provide strong primerless adhesion, which prevents separation from bonding surfaces and stops unwanted air leaks throughout the structure.
Firestopping Applications
Finally, products help protect life and property. These sealants close penetrations in fire-rated walls and floors, limiting the spread of fire and smoke. As a result, they play a crucial role in maintaining the integrity of fire protection systems.
Choosing the Right Construction Sealant
Ultimately, selecting the right construction sealant determines long-term performance. Proper surface preparation and correct installation directly impact durability and effectiveness. Because construction sealants are engineered for specific conditions—such as indoor or outdoor use, UV exposure, temperature extremes, and chemical resistance—matching the product to the application ensures reliable, long-lasting results.
