Foam sealant, also known as foam adhesive or polyurethane foam sealant, is a game-changer in the door and window industry. It has revolutionized how gaps are filled, replacing traditional materials like cement bags and rockwool.

Benefits of Foam Sealant:

Multifunctional: Foam sealant offers a powerful combination of properties: thermal insulation, waterproofing, sound insulation, and shock absorption.

Durable and Eco-Friendly: It boasts stable chemical properties, a long lifespan, and doesn't pollute the environment. It's also self-extinguishing in fires, exhibiting excellent fire safety performance.

Strong Adhesion: Foam sealant bonds firmly to surfaces like roofs and walls without additional adhesives. This strong adhesion helps resist wind and pressure, preventing leaks and drafts.

Superior Insulation: With an exceptionally low thermal conductivity, foam sealant offers superior insulation compared to traditional materials.

Waterproofing Expertise: The dense, closed-cell structure of foam sealant creates a near-impenetrable barrier against water, making it ideal for waterproofing applications. Spray application ensures seamless waterproofing and thermal insulation, eliminating leaks and drafts.

Promoting Innovation in Building Insulation:

In China, while foam sealant is still in its early stages of adoption, its potential for energy-saving construction is being recognized. The Ministry of Construction established a special working group to promote the use of foam sealant for thermal insulation and waterproofing in buildings.

Tips for Using Foam Sealant:

Fast-Expanding Filler: Foam sealant can effectively fill window and door gaps, expanding rapidly (70-80 times its original size).

Speed Up Drying: Lightly misting the surface before or after applying foam sealant can accelerate drying.

Protect Clothing: Due to its sticky nature, exercise caution to avoid contact with clothes as it can be difficult to remove.

Wide Range of Applications: Foam sealant is a versatile material used in various applications like door frame decoration, anti-theft door installation, balcony sealing, and PVC/aluminum window and door installation.

By understanding the advantages of foam sealant, construction professionals can leverage this innovative material to create energy-efficient and weatherproof buildings.
