What Drawings to Send to an Aluminum Window Manufacturer

What Drawings Should You Send to an Aluminum Window Manufacturer?

Why Drawings Decide Quotation Accuracy

An aluminum window manufacturer cannot quote a custom project accurately from a few photos and rough sizes. Custom aluminum windows depend on opening dimensions, frame type, glass build-up, thermal break, finish, hardware, wind load, drainage and packaging. When these details are missing, the supplier must guess—and the quotation becomes unreliable.

Sending the right drawings helps the manufacturer:

• Price the project correctly.
• Identify engineering risks early.
• Prepare shop drawings before production begins.

The sections below outline exactly what to include in your submission package.

1. Architectural Floor Plans

Floor plans show room layout, opening locations and how each window relates to doors, balconies, structural walls and interior spaces. They help the supplier understand whether a window is fixed, operable, paired with a sliding door, or connected to a curtain wall or storefront system.

Best format: DWG or DXF (CAD) files allow faster dimension checking. PDF plans are acceptable for preliminary review, but CAD files reduce errors during shop-drawing preparation.

2. Elevations

Elevations are the most important drawing type for any aluminum window project. They communicate:

• Window height, width and alignment.
• Mullion layout and facade rhythm.
• Floor level relationships.
• Corner conditions and large fixed-glass areas.

For villas, elevations help review floor-to-ceiling aluminum windows, corner windows and signature glazing features. For commercial buildings, they clarify repeated modules and wind-exposure zones.

Tip: If the design calls for minimalist aluminum windows or ultra-narrow sightlines, include elevations at 1:50 scale so the supplier can recommend a suitable profile system.

3. Window Schedule

A window schedule is the core document for quotation and production. It should list:

Without a window schedule, the supplier may miss units, duplicate units or misunderstand opening direction—all of which delay production.

4. Section Details

Wall sections and sill details show how the window connects to the building structure. They allow the manufacturer to review:

• Frame depth and installation clearance.
• Drainage path and weep-hole position.
• Flashing, sealant joints and anchor locations.
• Thermal break continuity at the wall-to-frame junction.

For coastal, high-rise or heavy-rain projects, section details are not optional. They are part of performance verification and directly affect water-penetration resistance.

5. Performance Requirements

Send any known performance targets:

• Thermal: U-Factor, SHGC (per NFRC 100).
• Air leakage: ASTM E283 or EN 12207.
• Water penetration: ASTM E331 or EN 12208.
• Structural wind load: ASTM E330 or EN 12210.
• Acoustic: STC rating or Rw value.
• Impact: Miami-Dade TAS 201/202/203, ASTM E1886/E1996.
• Safety glass: ANSI Z97.1 or EN 12600.

If you do not know the exact values, send the project location and building type. A qualified aluminum window manufacturer can recommend a code-compliant baseline.

6. Finish and Hardware Preferences

Define the following before requesting a quotation:

For coastal projects, always mention AAMA 2605 finish and stainless steel hardware to avoid premature corrosion.

7. Site and Delivery Information

For export projects, packaging and container loading directly affect cost and product safety. Provide:

• Delivery country and destination port.
• Site access limits (road width, crane availability).
• Maximum glass size restrictions (elevator, stairway, scaffold).
• Target installation date.
• Any labeling or customs documentation requirements.

These details help the manufacturer design crate dimensions, loading sequence, edge protection and container bracing.

Simple Submission Checklist

Send these files together when you contact an aluminum window manufacturer:

1. ☐ Floor plans (CAD or PDF)
2. ☐ Elevations (all facades)
3. ☐ Window schedule (mark, qty, size, type, glass, color)
4. ☐ Wall sections and sill details
5. ☐ Project location and applicable code
6. ☐ Wind load or design pressure
7. ☐ Glass preference (Low-E, laminated, tinted, etc.)
8. ☐ Frame color and finish standard
9. ☐ Hardware preference
10. ☐ Target delivery date

The more complete your submission, the faster and more accurate the quotation.

FAQ Schema

Can I request a quote without CAD drawings?

Yes, but the quotation will be preliminary. For accurate custom aluminum window pricing, CAD drawings, elevations and a window schedule are strongly recommended. Without them, the manufacturer must estimate dimensions—which increases revision cycles later.

What if I only have rough opening sizes?

You can start with rough sizes to get a budget estimate. However, final production should not begin until shop drawings are reviewed and approved against verified field measurements.

Should I send photos of the building?

Photos are useful for renovation projects and help explain site conditions—material of the existing wall, access constraints, surrounding obstructions. But photos should never replace drawings. Photos show context; drawings control dimensions.

Why does the supplier ask so many questions?

Good questions reduce risk. They help confirm thermal performance, structural capacity, drainage design, glass specification, hardware function and installation assumptions before production. A manufacturer that asks detailed questions is protecting your budget and timeline.

What file formats are preferred?

Most aluminum window manufacturers prefer DWG/DXF for CAD files, PDF for elevations and schedules, and Excel for window schedules. Large files can be shared via cloud link (Google Drive, Dropbox, WeTransfer).
