Glasstec 2026
Building the next chapter of high-performance facades
Dow at Glasstec 2026
Advancing the future of glass and façade performance. Explore the new façade renovation program, next generation of structural bonding and innovation for high-performance facades, incorporating a new Power Edge System that brings performance and durability to the next level.
The Façade Renovation Program
Supporting façade renovation and life extension of existing façades through silicone assessment, glass reuse, non-destructive disassembly, and data-driven carbon insights to support smarter renovation decisions.
Review. Reuse. Re-Bond. Extend.
Keeping existing façades in service can create environmental and economic value. Dow's Façade Renovation Program combines silicone expertise, glass reuse, façade assessment, and circular design principles to help extend façade life, reduce waste, and support lower-carbon renovation strategies. Through real-world projects and industry collaboration, the program is exploring how existing façades can remain valuable resources for the future.
Judge the silicone in the existing units, so renovation can be weighed against replacement on evidence.
Give recovered glass a second life as a backed panel, using the DOWSIL™ 7094 approach.
Take units apart intact and bond again, designing today for the disassembly of tomorrow.
Workstreams at different stages of maturity
Technical Assessment of Façade silicones
Assessing silicone in existing SG and IG units, so teams can judge renovation against replacement. Proven on Citi Tower, London.
Easier Removal
Cutting and debonding methods that bring glass and framing out intact and reusable.
Design for Disassembly
Designing today's façades, so they come apart cleanly in twenty years. What we learn taking façades apart now feeds directly into these design rules.
Ingredient Carbon Data
Carbon footprint and EPD data for façade silicones, so renovation and replacement can be compared on evidence.
Our solutions in action
Giving existing glass a second life
Working with Lüchinger Meyer Partner, glass from an existing building is being given a second life in a new façade, using the DOWSIL™ 7094 approach: existing glass panels were prepared, assembled, cured and installed on site using the DOWSIL™ 7094 approach. Impact and fire performance were also investigated.
- Existing glass coated with DOWSIL™ 7094 and backed with a metal sheet.
- Panels assembled and cured off site before installation.
- Impact and fire performance investigated.
- “Project of the Year 2025 – Sustainability (International) SFE award, with Lüchinger Meyer Partner. Delivered on-site, the solution also enables off-site application for greater project flexibility.
Citi Tower, London: Assessing renovation against replacement
With Scheldebouw, we assessed the silicone in the existing units at Citi Tower, so the project team could weigh renovation against replacement on evidence.
- Existing silicone assessed in Dow laboratories.
- Disassembly behaviour studied in detail.
- Silicone-to-silicone rebonding evaluated.
- Findings published and publicly available.
- Published
Taking façades apart intact
Documented with Scheldebouw, we studied how silicone bonded units can be cut and debonded so glass and framing come out intact and stay reusable.
- Oscillating cutter for quick debonding.
- Manual cutter with adapted blade for tighter control.
- Hot knife for controlled, clean separation.
- Silicone, glass and aluminium surface quality monitored.
Knowing the carbon in the silicone
We are building carbon footprint and life-cycle data for the silicones used in façades. Renovation only counts toward carbon saving if the material data behind it is verified — that is what this workstream is building.
- Carbon-footprint data are being developed at ingredient level.
- Environmental Product Declarations are under development.
- Silicon recycling and carbon capture routes explored.
- Intended to support façade level comparisons.
Designing tomorrow’s façades for easier disassembly
We are using lessons from today’s removal studies to explore design approaches that could make future bonded façade units easier to separate.
DOWSIL™ Power Edge System
One edge. One System.
The Power Edge System for insulating glass combines new spacer innovation with high performing structural silicones, benefitting from 50+ Years of durability and expertise.
It is ready to be integrated into structural glazing facades, captive designs and windows.
One Edge. One System. Built to last.
The core is the new DOWSIL™ Power Edge 3000, a silane-enhanced reactive thermoplastic spacer. The backbone is the higher strength and fast curing structural DOWSIL™ 3363 Silicone sealant, which provides up to 30% higher strength.
A narrower edge and a cleaner sightline, so more of the unit is glass and daylight.
Wider cavities, cold-bent and curved units, and more freedom to shape the façade.
A compliant edge accommodates movement and redistributes local edge deformation under modelled loading conditions.

Material characterization that enables advanced design
Our RTPS materials have been extensively characterized across a wide range of defoamation rates and service conditions. The resulting material models capture how the edge system responds under different loading scenarios, providing a foundation for advanced engineering analyses and simulation-driven design.
From handling to extreme loads
Material behaviour has been evaluated across loading rates ranging from slow building movements and handling operations to high-rate events, enabling more realistic prediction of edge-system performance.
Ready for engineering simulations
The characterized material models can support applications such as cold-bent glazing, façade movement analysis, handling assessments, impact studies, blast evaluations, and other project-specific investigations.

Innovation Preview - Structural Glazing
The Translucent Structural Silicone Strip.
A pre-cured structural silicone strip supplied in a controlled geometry. After contact with the prepared substrate, the interfacial bond develops chemically in place, supporting faster handling of assembled units.
*Innovation preview. Preliminary, lab-scale concept under development with partners.
Simple. Safe. Sustainable.
Delivered through productivity, reliability and material-efficiency benefits.
In preliminary laboratory testing, handling strength developed approximately one hour after contact. Fewer steps on the bonding line, with no mixing, no mix-ratio checks and no pump flushing at assembly.
The strip brings its own bond-line geometry — fewer operator-dependent tolerances and translucent enough to inspect the bond line.
A leaner bond that uses less silicone and reduces aluminum use, drops the spacer tape, and stays soft enough to cut for disassembly at the end of life.
From strip to bonded unit
A cured strip, a primer and an hour of contact time. Here is the sequence of assembly and the chemistry that makes it hold.
Why this thin cured silicone works
The primer reacts with the substrate, then the strip reacts with that primed face, and the bond is built chemically in place — the bond then develops chemically at the prepared interface. The primer and strip are specifically designed to form the required interfacial bond after assembly, unlike conventional cured structural-silicone components not designed for this bonding mechanism. The strip thickness and bite are fixed during upstream manufacture rather than formed by wet-sealant application during unit assembly.
The bonding sequence
The strip arrives pre-applied on the profile and is cut to length directly.
A few minutes for the primer to react with the glass surface.
Glass and profile are aligned before controlled contact is made.
Adhesion builds in place; the unit is ready to handle after about an hour.
What it does for production
- Controlled upstream manufacture. The bond line is made and cured in the factory rather than at assembly.
- Predefined geometry. Bite and thickness come with the strip, not from operator technique.
- Fewer wet-processing steps. No pumping equipment, no mix-ratio checks, no silicone logistics.
- Faster progression to handling. Approximately 1 hour to the defined handling criterion*. Against 24–48 hours for a conventional wet-applied joint, potentially supporting same-shift handling, subject to scale-up validation and production conditions.
*0.7 MPa maintained for 10 seconds in the Roman balance test. Preliminary laboratory data.
Less Material, More Glass
Compare conventional wet-applied structural glazing with Power SG 9000 to see how a thinner bond line can reduce the overall joint, use less material per unit, and enable a leaner façade section with more visible glass.
What it does for the façade
- 100% Silicone. Silicone Chemistry, UV-resistant and non-yellowing.
- Translucent. Reads as light rather than a black line, allows the bond line to be inspected and can be pigmented.
- Slimmer sightlines, more glass. A narrower joint puts less frame in view and more visible glass in the same opening.
- Movement at a thinner joint. Preliminary material data indicate that the 3 mm strip geometry retains movement capability for the investigated conditions.
- Leaner, and easier to disassemble. Less silicone and aluminium per unit. The thinner, softer joint allows easier cutting during disassembly than a thicker conventional wet-applied joint.
