More Insulation Capacity for Cold-Climate and High-Performance Projects
This outward-opening high-insulation aluminum casement window combines a deeper 78.3mm frame, a 35.3mm thermal break, Low-E insulated glass, and German G-U hardware for projects that need more than a standard residential window package.
Its increased glass capacity supports thicker double or triple glazing, while the side-hinged sash provides full ventilation without using interior space. It is well suited to custom homes, apartments, townhouses, villas, and light commercial buildings.
Why Builders Specify This High-Insulation Casement Window
The deeper frame and wider thermal break provide more room for insulated glass, larger engineered sashes, and stronger thermal and acoustic performance.
Deeper 78.3mm Frame
The deeper wall profile provides more space for insulation and thicker glazing, making the system a stronger fit for demanding residential and light commercial work.
Wider 35.3mm Thermal Break
A wider separation between the interior and exterior aluminum sections helps reduce direct heat transfer through the frame.
Up to 47mm Glass Capacity
The frame accepts thicker insulated glass units than the standard casement system, giving specifiers more flexibility for energy and sound-control requirements.
Low-E Double or Triple Glazing
Standard Low-E argon-filled double glazing is available with a 20mm cavity, while triple glazing can be selected for higher-performance project packages.
German G-U Hardware
German G-U hardware supports smooth outward opening and dependable locking. HK Kinlong hardware is also available in black or white.
Larger Engineered Sash Options
Standard and larger sash configurations are available, including engineered options up to 1000mm wide, 2500mm high, and 100kg after technical review.
Improved Acoustic Reference
The latest specification lists approximately 37dB sound insulation, helping reduce outside noise in homes, apartments, and light commercial buildings.
Flexible Project Integration
Single openings, fixed combinations, 90° and 135° corners, nail fin, mounting tabs, and a pleated retractable screen can be selected to match the project.

Which Thermal Break Casement Window Fits Your Project?
Both systems use 1.8mm aluminum profiles and outward-opening operation. The high-insulation option adds a deeper frame, wider thermal break, and greater glass capacity.
Standard Thermal Break Casement Window
A practical option for standard residential and cost-controlled project packages.
Best for homes, apartments, townhouses, and light commercial projects that need reliable thermal break construction with controlled overall cost.
High-Insulation Aluminum Casement Window
A deeper-frame system for thicker glazing, colder climates, and higher-performance specifications.
Best for projects that prioritize a wider thermal break, lower heat-transfer reference, greater insulated glass capacity, and improved acoustic control.

Frequently Asked Questions
When should I choose this high-insulation casement window?
Choose it when the project needs a deeper frame, wider thermal break, thicker glass package, or stronger thermal and acoustic performance than the standard casement system.
What is the minimum order quantity?
We offer flexible MOQs. You can order sample sets for evaluation, and we provide competitive tiered pricing for full container load (FCL) project orders.
Can the glass and sash configuration be customized?
Yes. Double or triple glazing, sash sizes, fixed panels, opening layouts, colors, hardware, screens, and installation options can be customized. Larger sashes require engineering review.
What information should I send for a quotation?
Send drawings, rough opening sizes, BOQ or a window schedule, quantity, project location, preferred glass, color, screen option, and required delivery time to info@amjbm.com.
What are the typical lead time and warranty?
Standard production can start from approximately 25 days after drawing and material approval. Larger customized projects commonly require 30–55 days. The standard warranty is 7 years.
