At Realgres, every shipment goes through a strict quality inspection before leaving our factory. Today, we're inspecting a batch of triple-glazed aluminum windows and doors for a Canadian project.
For builders and contractors, quality isn't just about appearance—it means meeting local building codes, improving energy efficiency, and ensuring long-term performance during harsh winters.
That's exactly what our inspection process is designed to guarantee.
Built for Canadian Climate
Canada experiences some of the coldest winters in the world. Choosing the right windows and doors can significantly reduce heat loss, improve indoor comfort, and lower energy bills.
The products in this project include:
- Triple-glazed insulated glass
- Argon gas filled between glass panes
- High-performance thermal insulation material inside the frame
- Thermal break aluminum profiles
- Excellent airtightness and waterproof performance
This combination helps reduce heat transfer and minimizes condensation, keeping interiors warmer and more comfortable during winter.
Certified for the Canadian and North American Markets
Every project must comply with local standards before installation.
These windows and doors are manufactured with internationally recognized certifications, including:
- CSA Certification for the Canadian market
- NFRC Certification for verified thermal performance
- ENERGY STAR® Qualified for superior energy efficiency
These certifications give contractors and developers confidence that the products meet strict requirements for performance, durability, and energy savings.
What We Inspect Before Every Shipment
Quality control is more than a final checklist. Our inspection team carefully verifies:
Glass Quality
- Triple-glazed construction
- Argon gas filling
- Glass surface inspection
- Edge sealing quality
Frame & Structure
- Thermal break profiles
- Surface finish
- Corner assembly accuracy
- Dimension tolerance
Hardware Testing
- Smooth opening and closing
- Lock performance
- Handle installation
- Roller operation
Packaging Inspection
Before loading, every product is securely packed with multiple layers of protection to prevent damage during international transportation.
Why Argon Gas and Thermal Insulation Matter
Many people know triple glazing improves insulation, but two additional features make an even bigger difference:
Argon Gas
Argon is an inert gas that slows heat transfer between glass panes, improving thermal performance while reducing condensation.
Thermal Insulation Core
Our insulated frame design helps prevent cold bridges, reducing the chance of freezing around the frame during extremely cold weather.
Together, these features help homeowners enjoy:
- Better indoor comfort
- Lower heating costs
- Reduced condensation
- Improved energy efficiency
