26 Jan Product Launch: Advancing Fire Safety & Performance – Introducing the New K-Foil Aluminium Foil Tape (EN13501-1: B-s1, d0)
As the construction and HVAC sectors continue to evolve, the pressure to specify safer, smarter, and regulation-ready materials has never been higher. Today, we’re proud to introduce a product built specifically for this new landscape: the K-Foil Aluminium Foil Tape, certified to EN13501-1: B-s1, d0.
This launch reflects our commitment to providing solutions that not only meet today’s expectations but anticipate tomorrow’s requirements. In a market where fire performance, airtightness, and long-term durability are essential, this tape is engineered to deliver all three with confidence.
Why This Product Matters Right Now
Across the UK, the industry is undergoing a major transition in the way fire performance is classified and assessed. The long-used “Class O” rating is being phased out and replaced with the more rigorous and comprehensive EN13501-1 Euroclass system.
This shift has created a clear need for materials that can demonstrate reliable fire behaviour using modern, internationally recognised testing standards.
That’s where K-Foil Aluminium Foil Tape stands out. With a B-s1, d0 classification — one of the strongest ratings available for limited-combustibility materials — it gives specifiers, installers and building control absolute clarity on its performance.
Understanding the Fire Rating: EN13501-1 B-s1, d0
To appreciate the significance of this product’s certification, it’s worth understanding what the rating actually measures:
B — Very Limited Contribution to Fire
This places the tape in a high-performance category, indicating that it does not significantly support flame spread and performs well in both open and confined fire scenarios.
s1 — Minimal Smoke Production
Smoke is one of the most dangerous elements in a fire. s1 is the best possible smoke rating, meaning the tape produces very little smoke when exposed to fire — supporting safer evacuation and clearer visibility in real-world conditions.
d0 — No Flaming Droplets
The product does not produce flaming droplets or particles. This reduces the risk of secondary ignition — a key factor in controlling fire spread through voids, ductwork, and insulated systems.
Together, these attributes make B-s1, d0 an exceptionally strong fire-safety profile for a foil tape product.
Engineered for the Demands of Modern Building Environments
While its fire rating is the headline achievement, K-Foil Aluminium Foil Tape brings a suite of high-performance features:
- 30-micron aluminium foil backing for strength and stability
- Water-based acrylic adhesive offering reliable, long-term bond performance
- White paper release liner for easy, clean application
- Excellent vapour-barrier properties, essential for maintaining insulation integrity
- High tack and durability, even in challenging environments
- Temperature resistance from 0°C to 80°C
- Available in standard and custom widths, including 50mm, 75mm and 100mm
These characteristics make it suitable not just for typical foil-tape applications, but for any installation where thermal efficiency, system airtightness, and fire performance intersect.
Where This Tape Delivers Results
The versatility of K-Foil Aluminium Foil Tape allows it to support a wide array of industrial sectors:
Construction
Sealing insulation boards, vapour control layers, and building fabric components.
HVAC, Ducting & Ventilation
Ensuring airtightness, sealing seams, and maintaining fire integrity in duct systems.
Aerospace & Automotive
Applications where weight, thermal behaviour and engineering precision are critical.
Asbestos Removal & Remediation
Providing a reliable seal in safety-controlled environments.
Thermal & Acoustic Insulation
Assisting with the creation of effective air and vapour barriers which protect insulation over its full lifecycle.
Every one of these sectors is under increasing scrutiny for fire performance — making the move to EN13501-1 rated materials not just advisable, but essential.
Preparing for the Future of Compliance
As regulations shift, products that still rely on older “Class O” classifications risk falling behind the curve. The introduction of Euroclass ratings has raised the standard and increased transparency around fire behaviour.
By launching a tape with B-s1, d0 certification, we are ensuring contractors, architects and engineers can specify with confidence — knowing the product already aligns with the direction the industry is heading.
This isn’t just about meeting a requirement.
It’s about doing things better.
