01 · Thermal break
Native PA66 thermal break
A 24mm PA66 polyamide strip mechanically rolled into the extrusion at the factory, not retrofitted with adhesive. Decouples the indoor and outdoor sides of the frame, cutting heat loss without thinning the wall.
02 · Hardware
Multi-point locking, 316 stainless
European multi-point locking hardware in 316 stainless. Locks engage at the top, middle, and bottom of every sash. Coastal install kits substitute 316 stainless hinges at no upcharge inside the warranty radius.
03 · Glazing
Double or triple, factory sealed
Standard build is double pane with a warm-edge spacer, argon filled, LowE coated. Triple pane is available on request for colder climates and adds 18mm to the overall sightline.
04 · Finish
Powder coat, 150 plus RAL colors
Two-stage powder coat applied after extrusion. Standard finish is 80 micron polyester. Coastal finish is 120 micron with a chromate primer. Specifiable in 150 plus RAL colors.
Energy performance certification (NFRC, AAMA) varies by product and is disclosed in writing on every quote. Suitable for renovation, replacement, and new-construction projects on cert-verified configurations.
Common questions
- What is the thermal break used in Crateworks windows?
- A 24mm PA66 polyamide strip mechanically rolled into the aluminum extrusion. PA66 is the standard polyamide for modern aluminum fenestration; it separates the outside and inside of the frame so heat does not conduct straight through.
- What hardware ships with a Crateworks window?
- European multi-point locking hardware in 316 stainless steel. Locks engage at the top, middle, and bottom of every sash. Coastal install kits substitute 316 stainless hinges at no upcharge inside the warranty radius.
- Double-pane or triple-pane glazing?
- Standard build is double pane with a warm-edge spacer, argon filled, LowE coated. Triple pane is available for cold climates and adds 18mm to the overall sightline. Acoustic configurations (STC 56) are available where sound performance is the spec driver.
- How is the frame finished?
- Two-stage powder coat applied after extrusion. Standard is 80 micron polyester; coastal is 120 micron with a chromate primer. Frame color is specifiable in 150 plus RAL colors. AAMA 2605 PVDF coating with 20-year finish warranty is also available.
