AllShield CoreShield - Hard mineral protection for combustible and vulnerable materials
Non-combustible mineral coating for full encapsulation of EPS and other core materials
AllShield CoreShield is a mineral-based protective coating that creates a rigid, non-combustible shell around EPS and other core materials. It is designed to shield vulnerable and combustible products from fire, strong acids, mechanical impact, and long-term environmental exposure.
This fast-curing system combines durability with speed, ensuring that even in demanding projects downtime is kept to a minimum. Applied by certified applicators using airless spray technology and reinforced with glass fleece, CoreShield cures into a seamless and watertight mineral layer.
By encapsulating materials such as EPS, CoreShield not only improves fire safety but also significantly extends the service life of products exposed to harsh conditions. The result is a robust, sustainable solution that is PFAS-free, VOC-free, and engineered for long-term performance.
CoreShield has already been used in infrastructure projects such as floating flood barriers, where mechanical strength, acid resistance, and fire safety must come together in one protective system.
How CoreShield works
CoreShield forms a hard, mineral-based layer that adheres directly to the surface of the product. Once cured and reinforced, it becomes a permanent shield that is:
Non-combustible and fire-resistant – prevents ignition and fire spread
Impact-resistant – withstands external mechanical stress and pressure
Acid-resistant – shields materials from strong acids and corrosive substances
Weather- and UV-proof – maintains performance under long-term exposure
Mineral-based and sustainable – PFAS-free, VOC-free, low CO₂ footprint
Easy install
CoreShield is applied by certified applicators using airless spray technology and reinforced with EKL™ 800/450 glass fleece. It cures quickly into a rigid, high-strength layer, ensuring products are fully encapsulated and protected.
Certifications and Compliance

Product information AllShield CoreShield
CoreShield is a two-component ceramic mineral system developed to create a hard and seamless protective shell around EPS and other core materials. Once applied and reinforced with glass fleece, it provides long-lasting resistance to fire, strong acids, mechanical impact, and environmental stress. The finish is seamless, waterproof, and UV-proof, ensuring reliable performance even under extreme conditions. Fully mineral-based, PFAS-free and VOC-free, CoreShield offers a sustainable solution that combines safety, durability, and environmental responsibility.

Projects AllShield CoreShield
Protecting what matters. Insurability starts with evidence. Our projects with AllShield CoreShield show how passive fire protection, low added roof load and documented system performance can be integrated into real commercial roof-PV projects
Frequently asked questions (FAQ)
What is AllShield?
AllShield develops mineral-based coatings and barriers for fire safety, acid resistance and structural durability — with no plastics, no PFAS and a low CO₂ footprint.
Are AllShield products really non-combustible?
Yes. AllShield Blue and BarrierSheets are A1 certified.
Are your products compatible with common materials?
Yes. Proven on over 80% of standard materials including steel, EPS, PIR, PUR, bitumen, PVC, TPO, EPDM (for BarrierSheet), wood and concrete.
What types of buildings use AllShield?
Industrial, commercial and critical infrastructure buildings, especially those with flat roofs, PV systems, chemical zones or aging membranes.
Are your products sustainable?
Yes. AllShield products are VOC-free, REACH-compliant and developed to reduce the environmental impact of the built environment.
Can AllShield BarrierSheet and AllShield Blue be used with PV systems?
Yes. AllShield BarrierSheet is our standard solution for PV roof assemblies and is FM 4478 Approved for applicable roof assemblies. AllShield Blue is FM 4484 Approved and remains available as a specialty solution for selected existing roof applications.
Do they extend the lifespan of roofs?
Yes. AllShield Blue coating offers UV, mechanical and chemical resistance; BarrierSheet protects membranes and insulation as a cover board below a new roofing membrane.
Are they waterproof?
AllShield BarrierSheet is not a waterproofing layer and must always be covered by a waterproof roof membrane. AllShield Blue forms a seamless protective coating but is not intended to replace the primary roof waterproofing system or to repair an existing leaking roof.
Can AllShield BarrierSheet and AllShield Blue be used for roof refurbishment?
Yes. AllShield BarrierSheet is our standard solution for roof refurbishment and PV retrofits and is installed beneath a new waterproofing membrane. AllShield Blue can be applied directly to suitable existing waterproofing membranes in selected projects where retaining the existing membrane provides a clear practical advantage.
What about insurers?
AllShield Blue is FM 4482 and FM 4484 Approved. AllShield BarrierSheet is FM 4470 and FM 4478 Approved. Acceptance by an insurer always depends on the complete roof and PV assembly and the project-specific risk assessment.
