Insulated Glass Units

Insulated Glass Units (IGUs) or "windows" come in many forms, thicknesses and finishing types. AGNORA specializes in creating high-quality IGUs for residential, retail and commercial spaces using the newest technology and practices to achieve a higher level of durability, clarity and performance.

Jumbo, oversized IGUs

The largest in North America

AGNORA is able to produce IGUs up to 130″ x 236″ (3.3 x 6m) on its automated IGU line with argon gas, and up to 130″ x 300″ (3.3 x 7.6m) with standard dry air.  Optionally, beyond 130″ x 236″ (3.3 x 6m) argon may be added manually. This immense capability allows the performance of double or triple glazed IGUs to be utilized in a wide array of high-end homes, retail, and commercial locations.

Durability above the rest

High Modulus Silicon

AGNORA’s High Modulus silicone creates less stress on the PIB primary seal, which translates to longer argon retention.

To continue to add more value and life to the units produced at AGNORA, we use DOW High Modulus silicone (Dowsil 3363), available in black or grey colour configurations. This silicone provides greater tensile strength compared to the leading competitor, translating to 30% less joint movement, thus creating a more durable primary seal and reduced argon loss.  In short, your windows are stronger and more resistant to seal failure.

The reason for using this more complex sealant?  Because every step of our process is about a higher level of quality, leading to increased durability.

Smart Technology

Scanning for Clarity

The use of SoftSolutions in-line scanner allows AGNORA to assess the overall quality of each individual piece of glass.  The scanner captures detailed information regarding surface defects such as hair, dirt, grease, or scratches, but also analyzes the surface of heat-treated glass to ensure the level of anisotropy or “leopard spotting” is agreeable.  All-in-all this technology ensures that the glass you receive is absolutely the best quality and clarity, no exceptions.

Performance Coatings in Stock

AGNORA carries an extensive inventory of glass with varying levels of performance coatings that work in tandem with your project requirements.  The following are examples of our top five (5) requested performance coatings and their maximum available sizes.
