THERMAL STEEL
Thermally-Broken Steel Windows and Doors
Technology
Arcadia Custom’ thermal steel technology was fueled by the need to produce a steel window and door that would meet the ever increasing stringent energy efficiency building codes of today and tomorrow while not losing any of the classic, timeless aesthetics that steel windows and doors have become known for. Thermal steel is a unique patent pending process utilizing modern materials and state-of-the-art computerized machinery that produce the most precise, energy efficient steel window and door on the market today.

- Lasers are used to cut windows and door parts out of 10 gauge stainless steel plates.
- Computerized Lasers ensure a level of precision and squareness not available through traditional means of manufacturing.
- Lasers cut all hardware and screw holes to guarantee accurate locations.
- Rectangular Plates are cut from single plates of steel so there are no welds at the corners, thus ensuring a smooth seamless finished surface.
- Stainless Steel ensures it will not rust.
- GRP (Glass Reinforced Protrusion), a thermal-break material, is a specifically engineered structural thermal insulator that is cut and processed using CNC equipment
- Stainless Steel Plates and GRP are bonded together through a strctural bonding process called “Thermal Mechanical Fusion”. This creates the finished frame, window sash, and door panel assemblies.
- High-performance insulated glass is installed in a controlled factory environment utilizing structural glazing techniques ensuring against water penetration.
- A fully welded decorative glazing frame is installed as one piece. This method provides a clean, precise finish fit with no unsightly open glazing-joints seen with typical installations.

Details
The hallmark of our thermal steel windows and doors comes from the durability of steel coupled with minimal aesthetics. With profile widths of one to two inches, we can produce narrow sight-lines and a lightness to the frame for a clean, crisp, modern look that provides security and increased durability over wood door alternatives.

Available Materials
Stainless Steel & Corten Steel

Performance
Thermal Performance
- NFRC Certified
- U-Values as low as 0.26
- The best energy performance in the steel window industry, with values rivaling high-performance wood windows
- Factory glazing means products will ship with NFRC label attached to glass
Condensation Resistance
- Thermally Broken design greatly reduces the chance of condensation seen with most steel and aluminum window construction.
- Product has gone through Condensation Resistance, or “CR”, testing with results similar to high-performance wood windows.
Stainless Steel Construction
- Stainless steel construction with paint finish means your door and windows will never develop “Structural Rust”.
- Chromium found in stainless steel prevents the migration of rust. Mild steel does not have this same natural protection.
Third-Party Testing
- Our product has gone through extensive independent engineering testing for air infiltration, water infiltration, design pressure, and structural testing.
- Arcadia Custom meets or exceeds industry standards in all these categories.
