Finding the best aluminium tape in Kenya means choosing a product that ensures your insulation is perfectly sealed, moisture-free, and durable.
At Bioflex Insulation Ltd, we supply high-quality heat-resistant aluminium tapes in two standard sizes — 50mm and 75mm widths — designed to deliver professional sealing results for HVAC systems, ductwork, cladding joints, and pipe insulation.

In this guide, we’ll help you understand when to use each size, what makes our aluminium tapes the best choice in Kenya, and how they enhance insulation efficiency across industries.

1. Why Aluminium Tape Matters in Insulation

In any insulation system — whether for pipes, ducts, or cladding — sealing is what guarantees long-term performance.
Even the best insulation materials lose efficiency if joints are left open.
That’s why aluminium tape plays a vital role: it creates a moisture-proof, heat-resistant, and airtight barrier, ensuring the insulation works as intended.

Using the right tape width improves both functionality and finish.

2. Available Sizes of Bioflex Aluminium Tapes in Kenya

At Bioflex Insulation Ltd, we offer two versatile options to meet different project needs:

Width	Ideal Use	Benefits
50mm Aluminium Tape	Smaller joints, narrow surfaces, pipe insulation, and finishing seams	Precise and flexible — great for tight spaces and clean edge sealing
75mm Aluminium Tape	Wide cladding overlaps, duct joints, and industrial insulation	Covers more surface area and improves weather protection

💡 Tip: Both 50mm and 75mm tapes perform the same sealing function. The main difference is coverage area and application convenience — choose based on your surface size and project type.

3. Features of Bioflex Aluminium Tapes

Our Bioflex aluminium tapes in Kenya are engineered for performance in all climates and industrial conditions:

• High Heat Resistance: Withstands up to 180°C, ideal for both hot and cold insulation systems.
• Strong Adhesive: Premium acrylic adhesive ensures lasting grip on metal, fibreglass, Armaflex, or Rockwool.
• Moisture-Proof: Prevents vapour and condensation from damaging insulation.
• UV and Fire Resistant: Perfect for outdoor use and high-temperature applications.
• Durable and Flexible: Tear-resistant yet easy to apply on curved or flat surfaces.
• Clean Reflective Finish: Leaves a professional, corrosion-resistant look.

4. Choosing the Best Aluminium Tape in Kenya for Your Project

(a) For HVAC and Duct Sealing

• Use 50mm tape for small air ducts or narrow joints.
• Use 75mm tape for large commercial or industrial ducts.
  ✅ Both maintain strong air-tight seals and energy efficiency.

(b) For Pipe Insulation

• 50mm tape is easier to apply around bends and curves.
• It ensures neat spiral wrapping without folds or wrinkles.

(c) For Cladding Overlaps and Outdoor Insulation

• 75mm tape provides wider coverage — ideal for sealing aluminium cladding sheets, outdoor ducts, and roof insulation joints.
• It enhances moisture protection in coastal or humid regions.

(d) For Cold Rooms and Refrigeration

• Either size can be used effectively — select 75mm for faster coverage of long seams.
• Prevents condensation, vapour leaks, and cold air loss.

5. Key Advantages of Using Bioflex Aluminium Tapes

• Locally stocked in Kenya for fast supply
• KEBS-approved and quality-verified
• Compatible with all insulation materials (Armaflex, Rockwool, Fibreglass, PU Foam, Cladding)
• Excellent performance in humid and hot environments
• Two convenient widths (50mm & 75mm) — fit for every project scale

By choosing the right size and proper application, you ensure both aesthetic finishing and long-term insulation protection.

6. How to Apply Aluminium Tape for Best Results

1. Clean the surface thoroughly — remove dust, oil, or moisture.
2. Cut the tape to the desired length (slightly longer than the seam).
3. Apply smoothly, pressing down to avoid air bubbles.
4. Overlap edges by 5–10mm for tight sealing.
5. Use a roller or cloth to apply firm pressure.
