5 Costly Mistakes to Avoid When Importing Aluminum Windows

Importing aluminum windows from overseas offers significant cost savings, but minor specification errors can lead to expensive delays. Avoid these 5 common mistakes to protect your investment.

1. Ignoring Local Building Codes

• The Risk: Windows rejected by customs or local building inspectors.
• The Solution: Verify required certifications before ordering (NFRC/SGCC for North America, CE for Europe, AS2047 for Australia).

2. Confusing Rough Opening with Frame Size

• The Risk: Windows manufactured too large to fit the structural wall opening.
• The Solution: Clearly state whether dimensions are Rough Opening (RO) or Actual Frame Size. Typically, deduct 10mm to 20mm from the RO for fitting clearance.

3. Skimping on Hardware Quality

• The Risk: Sagging sashes, broken handles, and rapid hardware corrosion.
• The Solution: Specify trusted brands (e.g., Siegenia, Roto, HOPO) and request 316 stainless steel for coastal projects.

4. Vague Glass Specifications

• The Risk: High energy bills, poor noise reduction, and severe solar heat gain.
• The Solution: Specify exact glass makeups, including Low-E coatings, Argon gas fill, and target U-values/SHGC.

5. Overlooking Export Packaging

• The Risk: Shattered glass or scratched frame finishes during ocean transit.
• The Solution: Require protective film, corner guards, and fully enclosed, fumigated IPPC wooden crates.
