At Klasse, we understand that in the built environment, quality isn’t optional - it’s critical. Whether it’s a rainscreen system on a high-rise building or sheathing boards on a new-build project, performance, compliance, and traceability underpin every decision we make.

Certified Assurance: ISO 9001 & ISO 14001
Klasse is proud to be:
-
ISO 9001 accredited – Ensuring our quality management systems are robust, consistent, and continuously improved.
-
ISO 14001 accredited – Demonstrating our commitment to environmental responsibility across sourcing, operations, and logistics.
These accreditations mean our customers can trust in both the performance and sustainability of our products.
Tested and Trusted: Performance You Can Rely On
We work closely with leading steel framing system (SFS) providers and independent testing houses such as BBA to validate our products through rigorous third-party testing. This ensures full compliance with UK Building Regulations and seamless compatibility within through-wall systems.
Our testing includes (but is not limited to):
- Reaction to fire testing (e.g., BS EN 13501-1)
- Through-wall fire testing (load bearing and non-load bearing scenarios)
- Structural and wind load performance
- Moisture resistance and vapour permeability
Partnering with our clients, Klasse can provide bespoke testing for specific project requirements.
A Commitment Beyond Compliance
At Klasse, we see quality and certifications as a starting point, not a finish line. Our team is committed to ongoing innovation, with every product shaped by feedback from sites, developments in construction science, and changes in national standards.
Why It Matters
Specifiers, contractors, and developers face increasing responsibility to deliver safe, sustainable, and regulation-compliant buildings. Klasse supports this mission by delivering products that are tested, trusted, and transparently certified.
When you choose Klasse, you’re not just choosing a product, you’re choosing peace of mind and technical support every step of the way.
