In today’s construction landscape, fire safety is no longer just a requirement – it’s a defining factor in façade design. With increasing scrutiny on materials and system performance, selecting the right solution has never been more critical.
At SAS Render Systems (SAS Europe), our systems are engineered to deliver dependable, proven fire performance. Both ProRend EIFS External Wall Insulation and ProWall Rendered Rainscreen provide specifiers, contractors, and building owners with complete confidence.
ProRend EIFS & ProWall Systems. Built for Compliance. Designed for Confidence.
Fire classification is more than a technical label – it’s assurance that your façade system is fit for purpose.
Working in line with BS EN 13501-1, our systems are designed to deliver appropriate fire performance depending on the project requirements:
- A2-s1,d0 → Limited combustibility, minimal smoke, no flaming droplets
- B-s1,d0 → Very limited contribution to fire with low smoke production
Allowing the correct solution to be specified based on building height, use, and risk profile.
ProWall Rendered Rainscreen, A Smarter Approach to Fire Safety
ProWall, with a 60-year BBA certificate for durability, is designed as a ventilated rainscreen system, enhancing fire performance while delivering a robust and durable façade.
- A2-s1,d0 fire classification as standard
- Suitable for steel frame and timber frame construction
- Fully aligned with current UK fire regulations
- Engineered using non-combustible components throughout
What sets ProWall apart is its ventilated design:
- Reduces heat build-up within the façade
- Limits potential fire spread pathways
- Integrates seamlessly with intumescent cavity barriers
The result is a system that not only complies with regulations but also actively contributes to improved building safety.
Ideal for:
- High-rise developments
- Education buildings
- Residential and commercial projects
ProRend EIFS, Flexible Performance Without Compromise
ProRend EIFS is a BBA-approved external wall insulation system offering adaptable fire performance, allowing systems to be specified to suit each project’s requirements, whilst providing a decarbonisation solution and enhanced insulation.
EPS Systems: Efficient. Economical. Energy-Saving.
- Provides excellent thermal efficiency and cost-effectiveness
- Typically achieves B-s1,d0 classification
- Commonly used to reduce heat loss or pre-existing structures, such as buildings with solid walls (no cavity) or older constructions.
A practical and proven solution for improving thermal performance with a breathable and weather-resistant rendered façade solution.
Mineral Wool Systems: High Performance Where It Matters Most
- Achieves A2-s1,d0 classification
- Suitable for higher-rise and higher-risk buildings
- Non-combustible and highly breathable
Combining thermal performance with enhanced fire safety, ProRend EIFS mineral wool EWI system meets the demands of modern construction.
It’s Not Just a Product – It’s a System
Fire performance is achieved through intelligent design and correct detailing.
SAS render systems are designed to incorporate, where required:
- Fire breaks at floor levels
- Intumescent cavity barriers at openings (within ventilated systems)
- Careful detailing around:
- Windows and doors
- Service penetrations
- System interfaces
Because even the best materials rely on correct design and installation to perform effectively.
