Description Arbo GZ Strip – Preformed Butyl Sealant �� What is butyl tape? Butyl tape is a preformed, non-curing sealant strip used to create watertight seals in glazing, roofing and cladding joints. Arbo GZ Strip is a high-performance butyl tape designed for compression joints, forming an instant seal without curing or tooling. Arbo GZ Strip butyl sealant is a preformed flat butyl sealant strip designed for the permanent sealing of compression joints in roofing, cladding, glazing, and guttering applications. It provides a durable, watertight seal by deforming under moderate pressure, allowing it to fully fill joint irregularities while maintaining long-term flexibility. With its strong surface tack and excellent recovery, Arbo GZ Strip forms a reliable moisture barrier that resists water ingress even in externally exposed environments. It is particularly well suited to glazing units in timber or metal frames, as well as lap joints in guttering and façade systems. Available in black and white, it delivers a clean, discreet finish that blends neatly with surrounding frames and substrates. �� What is butyl tape used for? Butyl tape is widely used for: Window and glazing seals Roofing lap joints Cladding panel joints Guttering and drainage sealing Weatherproofing external joints Its ability to remain flexible and waterproof without curing makes it ideal for long-term sealing in construction and glazing applications. ✅ Key Features & Benefits Preformed flat butyl sealant strip Excellent compression sealing performance Strong initial tack for secure positioning Good recovery for long-term sealing Ideal for external glazing & façade joints Excellent adhesion to porous & non-porous surfaces (when properly prepared) Clean, professional finish Available in black & white Long-lasting resistance to moisture ingress �� Typical Applications External glazing systems Timber & metal window frames Cladding compression joints Roofing lap joints Guttering and drainage joints Façade panel sealing Weatherproof perimeter sealing �� Choosing the Right Arbo GZ Tape Size For the best sealing performance, select a tape that is: Slightly wider than the joint Thick enough to compress by approximately 20–30% when installed ✅ Recommended Sizing Guide Joint / Gap Width Recommended Tape Width Recommended Thickness 3–5 mm 10–12 mm 3 mm 5–8 mm 15 mm 3 mm 8–12 mm 20 mm 4–5 mm 12–18 mm 25 mm 5–6 mm Following this guide ensures: Correct compression Maximum waterproofing Long-term seal integrity ✅ Why Choose Arbo GZ Strip?
