ClearVue Gen 3 Vision Glass Passes European Sealing Standard for Solar Facades
ClearVue’s Gen 3 Vision Glass achieves key European sealing certification
ClearVue Technologies (ASX: CPV, OTCQX: CVUEF) has announced its Gen 3 Vision Glass has successfully passed EN 1279-5:2018 testing, proving the company’s Gen 3 design is compatible with industry-standard aluminium spacers in double glazed unit (DGU) configuration. ClearVue’s patent-applied-for design enables power to be passed through the DGU seal without compromising hermetic integrity.
The certification, announced 23 June 2026, validates ClearVue’s approach to designing building-integrated photovoltaic (BIPV) products to meet the same durability standards as conventional glazing. Aluminium spacers are globally used by DGU manufacturers and specified in commercial curtain wall systems, making this certification directly relevant for construction industry adoption.
This milestone further de-risks ClearVue Vision Glass for builders, façade engineers and procurement teams, and confirms that aluminium spacer compatibility makes the certification directly relevant for the industry.

What is EN 1279-5 certification and why does it matter for BIPV?
EN 1279-5:2018 is the European standard governing long-term sealing performance of insulating glass units used in construction. The standard establishes safety and quality requirements, manufacturing and labelling guidelines, and the pathway for CE marking.
For BIPV products like ClearVue’s Vision Glass, certification to EN 1279-5 confirms the product meets the same hermetic integrity requirements as conventional glazing systems. This matters because façade engineers, builders, and procurement teams require proven durability guarantees before specifying products in commercial construction projects.
The standard certifies:
- Hermetic integrity of insulating glass units
- Long-term resistance to condensation within the IGU
- Protection of low-e coatings from water vapour and moisture ingress
- Compliance pathway for CE marking
Aluminium spacers are the industry standard in commercial curtain wall systems globally. By proving compatibility with this configuration, ClearVue has demonstrated its technology can slot into existing supply chains without forcing manufacturers to adopt specialised assembly processes.
The engineering breakthrough behind the certification
ClearVue’s Gen 3 Vision Glass incorporates patent-applied-for technology that enables the power cable to run through the seal without compromising the primary polyisobutylene (PIB) seal. This is not a retrofit solution — the Gen 3 product was engineered from the outset to meet certification requirements.
The certification validates several technical benefits:
- Power transmission through sealed IGU without seal compromise
- Long-term durability against internal condensation
- Protection of low-e coatings from moisture ingress
- Compatibility with standard aluminium spacers used in commercial curtain walls
The design enables integration with advanced low-emissivity coatings, delivering thermal performance improvements that align with net-zero building specifications. ClearVue’s approach prioritises designing products to meet certification standards rather than attempting to certify existing designs retrospectively.
This engineering discipline reduces the risk of costly redesigns or performance limitations discovered late in the commercialisation process.
CEO outlines commercial implications of certification milestone
Chief Executive Officer and Managing Director Douglas Hunt positioned the certification as validation of ClearVue’s product development methodology.
Douglas Hunt, Chief Executive Officer and Managing Director
“Every certification we achieve is a direct outcome of how we design and manufacture our products. We design to be certified, not the other way around. These bespoke components having passed EN1279-5 standard is a meaningful step forward because it validates the key design features of our Gen 3 Vision Glass that are pivotal to easy manufacture and installation. Combined with a variant of our recently certified thermal management junction box, it provides the key to the delivery of more power and lower costs to our clients. Our customers need certainty of reliability and longevity. Accelerated aging testing like this simulates decades of real world deployment and proves BIPV can be at least as reliable as standard glazing.”
Hunt noted the certification works in combination with ClearVue’s recently certified thermal management junction box variant, enabling the delivery of more power at lower costs. The accelerated aging testing simulates decades of real-world deployment, providing evidence that BIPV products can match or exceed the reliability of standard glazing.
This positions ClearVue as a commercially-ready BIPV supplier rather than a technology demonstrator still validating core product performance.
Where this certification fits in ClearVue’s product roadmap
The EN 1279-5 certification is part of ClearVue’s ongoing programme to design, validate, and certify BIPV products to international standards. The thermal management junction box certification, achieved recently, complements this milestone by addressing the electrical infrastructure required to extract power from the glazing system.
The Thermal Management Junction Box certification, awarded by TÜV SÜD against IEC 62790, confirms the electrical infrastructure component that extracts power from the glazing system meets international safety standards rated to 1000V and 30A with IP68 waterproofing.
Together, these certifications de-risk ClearVue Vision Glass for builders, façade engineers, and procurement teams who require documentation of compliance with construction standards.
| Component | Standard | Status |
|---|---|---|
| Gen 3 Vision Glass IGU | EN 1279-5:2018 | Passed |
| Thermal management junction box (variant) | Recently certified | Certified |
Progressive certification builds the compliance portfolio required for commercial-scale deployment in regulated construction markets. Specifiers in Europe and other jurisdictions that reference European standards will require evidence of EN 1279-5 compliance before approving BIPV products for use in curtain wall systems.

Investment outlook for ClearVue’s BIPV technology
The certification milestone reduces technical and commercial risk for potential customers by providing third-party validation that ClearVue’s products meet the same durability standards as conventional glazing. Building-integrated photovoltaics must deliver decades of reliable performance to justify their integration into building envelopes, where replacement costs are prohibitive.
ClearVue continues to target net-zero building solutions through solar façade, cladding, spandrel, balustrade, and skylight applications. Each certification achieved incrementally validates the company’s path from technology developer to commercial supplier.
The Cyprus BIPV retrofit contract, a A$305,000 engagement covering more than 800m² of the Rio Business Centre in Paphos, illustrates how ClearVue’s certified product credentials translate into commercial orders, with the client selection criteria explicitly referencing IP68 water resistance and fire ratings.
The EN 1279-5 certification specifically addresses a technical barrier that could have delayed or blocked adoption in commercial construction projects: compatibility with industry-standard manufacturing processes and materials. By proving its Gen 3 Vision Glass works with aluminium spacers in DGU configuration, ClearVue has removed the need for façade engineers to redesign their assembly workflows.
This supports revenue progression as the product portfolio meets the technical and regulatory requirements imposed by specifiers, contractors, and building certification schemes.
