The GOAT - Airtight Liquid Grommet - Airtight Flexible Sealant

The Goat – Airtight Flexible Sealant

Product Description

The Goat is a high-performance, liquid-applied flexible sealant engineered to provide complete airtight and waterproof sealing around service penetrations and junctions in the building envelope. It is a reactive polymer-based sealant that cures to form a resilient, elastic barrier capable of expanding and contracting with structural movement while maintaining long-term performance.

Designed for use around penetrations such as pipes, cables, conduits and other services passing through walls, floors and ceilings, The Goat eliminates common leakage points that compromise energy performance and airtightness continuity. Its flexibility and adhesion across a range of substrates ensure a durable, seamless seal to support high-performance building standards.

Key Features and Benefits

• Flexible, liquid-applied polymer sealant with high elongation (>400%) and tensile strength.
• Forms a continuous, airtight and waterproof seal.
• Accommodates thermal movement, humidity changes and differential substrate movement.
• VOC-free formulation with good UV resistance.
• Versatile adhesion to common construction materials, including masonry, concrete, timber and insulated panels.
• Easy application using standard cartridge gun equipment.
• Suitable for new build, retrofit, domestic and commercial applications.

Typical Applications

The Goat is suitable for sealing:

• Service penetrations through airtight and vapour control layers
• Junctions between different substrate materials
• Structural interfaces where airtight continuity is required
• Wall, floor and ceiling penetrations to eliminate air leakage paths
• Detailing zones around mechanical and electrical services

It ensures airtight continuity in both internal and external conditions where durable sealing and flexibility are critical.

Benefits for Airtight Design

The Goat provides a reliable sealing solution at critical junctions that are often prone to failure in airtight systems. Its elastic performance helps maintain airtight continuity in areas of movement without compromising long-term durability or performance
