Laminated Glass & Certified SentryGlass Fabrication in Ottawa
Raw Glass Inc fabricates and supplies laminated glass for commercial, institutional, and residential projects across Eastern Ontario. We’re a certified laminator for SentryGlas interlayer products, giving architects and builders access to structural-grade laminated glass, not just standard safety glazing.
Laminated Glass Interlayers
Laminated glass bonds two or more panes together with an interlayer in-between. Unlike tempered glass, which shatters into loose granules, laminated glass holds together when broken, which is why it’s specified anywhere safety, security, or structural performance is on the line.
Typical Applications
- Storefronts and curtain walls.
- Guardrails and balustrades (interior and exterior).
- Overhead and sloped glazing.
- Stair and landing panels.
- Glass floors.
- Facades.
- Decorative and branded glass features.
Selecting the optimal laminating film is critical to the structural integrity, longevity, and optical clarity of your architectural glass project. While Polyvinyl Butyral (PVB) has long been the standard for traditional safety glass, advanced polymer engineering has introduced high-performance alternatives like Ethylene Vinyl Acetate (EVA) and Ionoplast (SentryGlas). Because of the superior properties, Raw Glass fabricates laminated glass in Carleton Place using EVA and SentryGlass Xtra®️ (SGX®️) interlayers.
SentryGlass Xtra®️(SGX) Interlayer
SGX interlayers make laminated glass significantly stronger, giving it the ability to protect against high-impact forces while retaining structural integrity even after the glass breaks — often specified where standard tempered glass no longer meets the performance level required. SGX-laminated glass can be exposed to weather without a frame, all while maintaining outstanding optical clarity. Raw Glass Inc is a certified laminator for SentryGlas interlayer products — a credential that confirms our fabrication process meets the manufacturer’s structural and quality standards, not just a general laminating claim.

EVA Interlayer
EVA (ethylene-vinyl acetate) interlayers open up a wide range of design possibilities — colored films, mesh, metals, fabrics, wood veneers, and more can all be laminated into the glass for unique visual effects. Beyond aesthetics, EVA interlayers add real functional value: enhanced safety, thermal and sound insulation, and strong bonding performance.

Interlayers Comparison
Each interlayer material exhibits vastly different material properties, thermal behaviors, and moisture sensitivities. To help architects, structural engineers, and interior designers specify the correct material, our technical team has synthesized the critical quantitative performance metrics below. Whether your project demands the extreme structural stiffness of SGP for hurricane zones, the economical impact protection of PVB, or the zero-delamination moisture resistance of EVA for frameless outdoor balustrades, here is how the industry’s leading interlayers compare.
| Feature | PVB (Polyvinyl Butyral) | EVA (Ethylene Vinyl Acetate) | SentryGlas (SGP / SGX) |
|---|---|---|---|
| Primary Use | Standard indoor safety glass & automotive windshields. | High-humidity, open edges, & decorative inserts. | High-security, hurricane zones, & structural glass. |
| Water Absorption | ⚠️ High (3.0% – 5.0%) Absorbs moisture like a sponge. |
🏆 Ultra-Low (< 0.2%) Completely waterproof. |
✅ Low (< 1.0%) Excellent weather resistance. |
| Edge Delamination Risk | High. Edges turn cloudy and bubble over time if exposed. | None. Ideal for frameless, exposed edges. | None. Highly stable in exposed outdoor areas. |
| Heat Performance | Thermoplastic (0%) Can soften, sag, or slip under intense sun. |
Thermoset (> 85% cross-linked) Will not re-melt or slip in high heat. |
Thermoplastic (0% but rigid) Excellent temperature resistance. |
| Structural Stiffness | Low. Becomes highly flexible and sags if glass breaks. | Moderate. Excellent for standard balustrades and partitions. | 🏆 Extreme (100x stiffer than PVB) Holds weight even if both glass sheets break. |
Which Variant Do I Need*
EVA interlayers are ideal for frameless outdoor, high-humidity, and decorative applications, while SGP is engineered for high-strength structural projects like floors and canopies. PVB offers a cost-effective solution for standard acoustic or impact protection in traditional framing. Raw Glass’ technical experts are available to analyze project-specific load requirements and environmental factors for the correct specification.
*This is a simplified guide – always confirm the correct variant and rating with your architect, code official, or Raw Glass Inc rep based on your specific application.

Frequently Asked Questions
What’s the difference between EVA and SGX (SentryGlas) interlayers?
EVA interlayers are well suited to decorative and design-driven applications – colors, patterns, embedded materials, plus added safety, thermal, and sound performance. SGX interlayers are built for structural performance, offering greater strength and post-breakage integrity for applications like guardrails, overhead glazing, and unframed exterior installations.
Is laminated glass the same as tempered glass?
No. Tempered glass is designed to shatter into small, granular pieces for safety. Laminated glass uses an interlayer to hold the glass together after breakage, which is why it’s specified for applications like overhead glazing, balustrades, and security glass where fragments falling or flying apart would be dangerous.
Can laminated glass be used outdoors without a frame?
SGX-laminated glass can be exposed to weather and doesn’t need to be framed, while maintaining clarity and structural performance — a good fit for applications like frameless balustrades and guardrails.
Do you supply laminated glass without installation?
Yes, Raw Glass Inc offers laminated glass as a supply-only option or as a fully installed solution.
