AlphaGuard Blueshield from Tremco: Proven performance. Standout fire compliance

By Tremco Roofing.

This product highlights the extensive independent fire testing Tremco has commissioned delivering total peace of mind to specifiers and building owners.

With space across the U.K. at such a premium, utilising every available inch can bring a whole host of benefits. With AlphaGuard Blueshield from Tremco, external finishes can be applied at roof level meaning, buildings can be optimised to encompass a range of recreational and sustainable finishes from paving with seating and planters, to green and blue roofs. This can help encourage local biodiversity, support the human need for nature in the built environment and mitigate flood risk (SuDS).

Tremco recognises the importance of independent testing to reassure building stakeholders. In response, they have sought extensive testing to ensure its tailored systems are perfectly aligned to the specific requirements of sustainable roofs being:

• Highly durable: Designed to withstand the load bearing weight of external finishes whether a podium or green roof.
• Resistant: Engineered with root resistant technologies to avoid puncture causing water ingress.
• Environmentally friendly: Ensuring no toxication to the living nature of green roofs and biodiverse roofs.
• Safey and compliance: Meeting the latest building standards for thermal efficiency and fire safety.

Focussed on fire performance

The AlphaGuard Blueshield system has been extensively tested and independently certified by the BBA in the UK with the highest possible fire classification; Broof(t4) under BS EN 130501-5 2016.

Tremco's team was comprehensive in their approach, testing a broad range of scenarios combining AlphaGuard Blueshield with varying insulation types (EPS and XPS) and thicknesses to ensure that all solutions were compliant with thermal efficiency standards whilst achieving Broof(t4) classification.

The system has also been vigorously fire tested with external finishes, including sedum, ballasted and paving systems for green roofs, recreational podiums and for the foundation for solar PV. Additionally, further fire tests were carried out to include a blue roof build-up, testing with sedum, ballasted and paving systems.

Tremco’s expanded approach to testing means that the build-up, with its combined elements, work harmoniously together in mitigating the risks of fire. It should be reassuring that whether an inverted or blue roof inverted system is required – AlphaGuard Blueshield is fully compliant to fire safety requirements. The NHBC considers fire performance a key component of building safety. Therefore, the thorough approach Tremco has adopted should give specifiers total peace of mind.

Alongside the extensive fire testing, it also has a certified durability of up to the design life of the roof of which it is incorporated. The system complies with BS 6229:2018 and guidance outlined in NHBC technical requirements for flat roofs and balconies.

Expertly formulated by chemists to be safe for the environment, along with its ease of application, AlphaGuard Blueshield delivers the perfect balance between design, aesthetics, durability and practical performance.

AlphaGuard Blueshield has been specified in numerous prestigious and demanding builds such as; Tottenham Hotspurs new stadium, where the 16,000m2 area required an effective and proven inverted system at podium level. Then there is the multi award winning Battersea Reach development on the banks of the River Thames in the heart of London. Here AlphaGuard Blueshield is the foundation for the roof, terraces and podiums across the whole 8000m2 project.
