The GOAT Liquid Grommet - Airtight & Flexible Sealant (Box of 6 310ml mastic tubes)

Liquid Airtight Grommet: The Future of Airtight Sealing

Welcome to the revolution in building airtightness. Say goodbye to outdated, rigid plastic grommets and embrace the superior performance and flexibility of our Liquid Airtight Grommet! At Intelligent Membranes, we’ve developed the ultimate solution for airtight sealing, ensuring your building is energy-efficient, airtight, and future-proof. Our Liquid Airtight Grommet is a game-changer in the industry, providing an unparalleled alternative to traditional grommets for sealing penetrations around pipes, cables, and conduits.

Why Choose Our Liquid Airtight Grommet?

1. Flexibility Like Never Before
   Traditional plastic grommets are limited in shape and size, often leading to awkward fits and compromised seals. Our Liquid Airtight Grommet adapts seamlessly to any size or shape, filling every nook and cranny to create a perfect, customized airtight seal. No matter how irregular the opening, our liquid grommet flows and forms an impenetrable barrier where plastic grommets fall short.
2. Effortless Application
   Forget about fiddling with rigid grommets, cutting, or resizing them to fit. The Liquid Airtight Grommet can be applied in seconds, with a cartridge gun. It’s quick, hassle-free, and bonds directly to the building fabric, creating a seamless, airtight layer. Whether you’re working with timber, brick, or concrete, our solution provides an airtight seal that traditional grommets simply can’t match.
3. Superior Airtightness
   We don’t just match the performance of plastic grommets—we surpass it. Our liquid-applied solution ensures complete airtightness by eliminating the potential for gaps or leaks. When cured, the Liquid Airtight Grommet forms a durable, flexible membrane that withstands building movement and weather conditions, maintaining a high-performance seal over time.
4. Total Versatility
   Our Liquid Airtight Grommet is perfect for both new builds and retrofit projects. Whether you’re working on a Passivhaus project or simply looking to improve the energy efficiency of an existing building, this product is the ultimate solution. It can be used on a wide range of penetrations, including cables, pipes, ducts, and conduits, giving you one product that solves all your airtight sealing needs.
5. Energy Efficiency Redefined
   By using our Liquid Airtight Grommet, you dramatically reduce air leakage, helping to keep your building warm in the winter and cool in the summer. This improves the overall energy efficiency of your project, reducing heating and cooling costs while lowering your carbon footprint. It’s a smart, sustainable choice for any modern construction.

How It Works

Our Liquid Airtight Grommet is applied directly over or around the penetration point using a cartridge gun. It adheres to the surface and, as it cures, forms a seamless, airtight barrier that expands and contracts with the building over time. It’s designed to withstand temperature changes, humidity, and building movement, ensuring long-lasting protection.

Applications

• Timber Frame Construction: Ideal for sealing penetrations in timber structures, maintaining airtightness without compromising breathability.
• Brick and Block Walls: Easily adheres to rough surfaces, forming a complete seal around pipes, cables, or conduits.
• Concrete: Provides exceptional adhesion to concrete surfaces, making it perfect for large-scale commercial or industrial projects.
• Retrofit Projects: Perfect for upgrading existing buildings to meet modern airtightness standards.

Why We’re Awesome

At Intelligent Membranes, we don’t just create products—we innovate to solve problems. Our Liquid Airtight Grommet is the result of years of research, testing, and a commitment to pushing the boundaries of airtight technology. We understand the demands of modern construction, and that’s why we’ve created a product that not only works better but makes your life easier.

With our Liquid Airtight Grommet, you’re not just sealing penetrations—you’re future-proofing your building. Whether you’re working on a cutting-edge Passivhaus build or simply upgrading an older property, this product will give you the airtight, energy-efficient results you need to succeed.
