Why Doesn't Every Carton Cover Exactly the Same Area?

Different siding profiles have different exposures, widths, joint details, and packaging configurations. Although both ASCEND profiles are designed for efficient installation, the physical dimensions of each panel determine how much wall area a carton covers.

The manufacturer packages each profile to simplify handling and estimating rather than making every carton identical in square-foot coverage.²

How Many Cartons Will My Project Need?

The number of cartons required depends on much more than the wall square footage. Professional estimates also account for:

• Windows and doors
• Gable walls
• Roof intersections
• Outside and inside corners
• Waste from cutting panels
• Starter rows and finishing pieces
• Color and profile changes
• Future repair material

Ordering only the exact wall square footage can leave a project short of material, while ordering excessive quantities increases cost and storage requirements.

Should Contractors Order Extra Material?

In many cases, yes. Most professional installers include an appropriate waste allowance based on the design of the home. Complex elevations with dormers, multiple gables, numerous windows, and architectural details generally require more cutting than simple rectangular walls.

Contractors also frequently keep one or two extra panels available for future repairs, particularly if a color is discontinued or production batches change over time.

Why Accurate Estimating Matters

Accurate estimating helps reduce project delays, minimizes unnecessary material handling, and allows installers to complete the job with fewer interruptions. Ordering the correct number of cartons also improves scheduling, inventory management, and jobsite efficiency.

At Suburban Wholesale & Supply, our team helps contractors calculate complete material packages—including cladding, trim, starter strips, corners, accessories, and fasteners—to reduce surprises once installation begins.

The Bottom Line

ASCEND carton coverage varies by profile. The 7-inch Horizontal Plank is packaged with 14 planks and covers approximately one square (100 square feet) per carton, while the 12-inch Board & Batten is packaged with eight panels and covers approximately 96 square feet per carton.

Rather than estimating solely by carton count, contractors should measure the project, account for waste, and verify profile-specific packaging before placing an order. A complete takeoff helps ensure enough material is available for a smooth installation while minimizing excess inventory.
