Description
Arbo GZ Strip – Preformed Butyl Sealant
Arboseal GZ is a flat butyl sealant strip designed to seal compression joints in cladding or roofing, lap joints in guttering, and glazing units in timber or metal frames. The performed strip deforms under moderate pressure, has a strong tack and good recovery, giving a durable seal against moisture.
- Ideal for external glazing sealing where flexible butyl is required
- Excellent adhesion on porous and non-porous surfaces when properly prepared
- Clean finish (avaliable in black & white) that blends with frames or substrates
Choosing the Right Arboseal GZ Tape Size
For the best seal, select a tape **slightly wider than the joint** and thick enough to compress by around 20–30 % when fitted.

| Joint / Gap Width | Recommended Tape Width | Recommended Thickness |
|---|---|---|
| 3–5 mm | 10–12 mm | 3 mm |
