Windows Performance Metrics

We have our testing lab that mimics the NFRS's testing lab to continuously test what we manufacture. Compare our numbers against others and ask our WindowsGPT about what the figures mean to know more.

Performance comparison table showing technical specifications for two window product lines: Defender 76TS (available in Double and Triple glazing) and Defender 88PH+ Pro & XI (available in Triple glazing, Pro and XI variants). Metrics include air and water tightness, structural performance, thermal values, and energy efficiency ratings.

Our Window Anatomy

Below we breakdown the anatomy of our window and what makes each part special in solving a problem that most windows have. We're proud of our engineering and your builders will know the quality and thought put into the components.

Defender 76 TS window cross-section anatomy showing numbered components and internal structure

  • Typical Issues:

    Traditional window installations often rely on tapes and sealants to keep moisture out. Over time, these materials degrade due to UV exposure, fluctuating temperatures, and material expansion—especially with low-quality vinyl frames—leading to leaks, mold, and costly repairs.

    Our Advantage:

    We use a fully dry-glazed system—no tapes or sealants needed. Combined with our pressure-equalized Hybrid Framing design, this system manages moisture through intelligent drainage and ensures water has a clear path out. The result: long-lasting, maintenance-free protection against the elements.

  • Typical Issues:

    Without proper internal reinforcement, window frames can bend, warp, or sag—especially larger ones. This compromises not only the structure but also energy efficiency, air tightness, and security. Poor steel quality or minimal reinforcement compounds the problem.

    Our Advantage:

    We embed performance-grade galvanized steel directly into our window frames, sashes, and mullions. This dramatically increases structural strength and allows for oversized units without bowing or flexing. It also stabilizes thermal expansion, so your windows stay true and functional through all seasons.

  • Typical Issues:

    Face-sealed windows fail over time. Their exposed seals degrade, letting water infiltrate unnoticed until it causes interior damage. Drilled weep holes offer inconsistent protection and are often ineffective.

    Our Advantage:

    Our engineered drainage system uses pressure equalization and continuous seals to redirect moisture safely outside—before it causes damage. Scientifically tested and proven, this system is designed for long-term performance in harsh weather.

  • Typical Issues:

    Shallow window frames with minimal internal chambers allow more heat loss and increase the risk of drafts through convection and thermal bridging.

    Our Advantage:

    Each of our window profiles features a deep 76 mm (3") frame with six internal chambers. This design traps insulating air, resists twisting forces, and dramatically reduces energy loss—keeping your home quieter, more comfortable, and more efficient.

  • Typical Issues:

    Many window profiles use thin-walled vinyl to reduce manufacturing costs. While cheaper, these frames are more prone to cracking, bending, or breaking—especially at the corners.

    Our Advantage:

    We manufacture all our profiles using thick, rigid, lead-free uPVC. These robust extrusions add structural strength, improve durability, and form the foundation for a long-lasting, high-performance window system.

  • Typical Issues:

    Window corners that are only screwed or mechanically fastened can weaken over time, especially during transport or installation. Micro-cracks may develop into air or water leaks—and eventually failure.

    Our Advantage:

    We precision-mitre and heat-weld all corners for a seamless, ultra-strong joint. Combined with our thick profiles, this creates a rigid, leak-resistant frame that performs consistently—even under heavy wind or handling stress.

  • Typical Issues:

    Basic aluminum spacers conduct heat, reducing a window's insulation. On the flip side, some non-metal spacers insulate well but don't provide enough structural strength, leading to seal failure.

    Our Advantage:

    We use Cardinal Endur IG® stainless steel warm-edge spacers, which strike the perfect balance between thermal insulation and rigidity. Paired with a deep glazing cavity, this delivers superior energy efficiency and long-term durability for your sealed units.

  • Typical Issues:

    Triple-glazed units are heavy and require precise spacing to be effective. Many standard windows aren't built to handle this weight, and their narrower cavities often force glass panes too close together—reducing insulating value.

    Our Advantage:

    Our advanced glazing system is engineered to support heavy, high-performance triple-pane units with ideal ½" spacing between each pane. Reinforced sashes, steel cores, and precision hardware ensure reliable performance without stress or sag.

  • Typical Issues:

    Ordinary window hinges are often secured directly into vinyl, which can strip out over time—especially in larger, frequently used windows. This causes sagging, drafts, and poor operation.

    Our Advantage:

    Our Defender hinges bolt directly into the steel core of the frame and offer full three-way adjustability. This prevents sagging, improves long-term usability, and allows for smooth operation even in large or triple-glazed sashes.

  • Typical Issues:

    Low-grade finishes fade, peel, or bubble when exposed to the elements—creating a worn appearance and requiring expensive refinishing.

    Our Advantage:

    We offer advanced surface finishes—both laminated and coated—engineered for long-term durability. These options resist scratching, fading, peeling, and bubbling, keeping your windows beautiful and low-maintenance for years to come.

Net Zero Energy

Not All Certifications Are Equal

Why do certifications matter? Quality Engineering. Obtaining Passive House certification is hard and is an indicator of the engineering and research standards of the manufacturer. In Canada, the National Energy Code has 4 tiers aiming for homes to be at tier 4 (Net Zero Ready) by 2030. Passive House exceeds even Net Zero. Energy Star is Tier 1. Innotech's windows are Passive House. Know which certifications actually matter in giving you guidance on what's superior build quality.
