Adding SKUs shouldn’t mean subtracting sales—here’s how glass distributors can grow the catalog without shrinking margins.
As glass distributors expand their portfolios to serve architectural, automotive, and solar markets, cannibalization becomes a real threat. Introduce too many overlapping SKUs—like multiple types of laminated safety glass, or two low-E coatings that serve similar applications—and you risk confusing customers, diluting demand, and eroding your margins.
Cannibalization occurs when new SKUs don’t grow the pie—they just cut it differently. That’s fine if you’re taking share from a competitor, but dangerous when your new line eats into your own top performers. The good news? Cannibalization is avoidable with disciplined product planning.
Map Use-Cases Before You Add SKUs
Every new product should be tied to a specific, validated use-case. Don’t just add triple-glazed IGUs because a competitor does—add them because you have a customer segment demanding better U-values for Northern climate commercial builds.
If you can’t map a new glass SKU to a distinct application, customer segment, or market trend, you risk creating internal competition. Better to enhance visibility or lead times on your existing IGU line than dilute it with an underdeveloped offering.
Protect High-Margin SKUs
New, low-cost imports can quickly steal share from premium glass products if positioned poorly. If your 5mm low-iron tempered line has become a high-margin staple, think twice before introducing a slightly cheaper version with similar specs unless you’re clearly targeting a separate buyer profile.
One solution? Create price-tiered families (e.g., Standard, Premium, Ultra) with different service levels, so customers can self-select without defaulting to the lowest price.
Align Sales Incentives With Margin Goals
Cannibalization often stems from the sales floor. Reps may push new SKUs aggressively because they’re fresh—but if commission plans don’t factor in margin protection, they’ll push volume, not value. Consider SPIFs or bonuses for maintaining mix quality, not just hitting tonnage.
Use a Customer Choice Model
Instead of launching multiple SKUs simultaneously, A/B test them with different client segments. Use structured feedback from inside sales and field reps to determine which new SKUs fill a gap, and which ones just fragment your catalog.
Monitor SKU Mix Weekly
The longer you wait to spot cannibalization, the harder it is to reverse. Track mix changes, margin by product line, and lost sales on original SKUs after a new launch. A sudden drop in your ½” tinted line after introducing a new shade is a red flag. Be ready to adjust fast.

Expanding your glass product line should unlock new revenue, not reshuffle existing dollars. With careful positioning, cross-functional planning, and data-driven monitoring, distributors can avoid the trap of cannibalization. Growth is good—but only if it’s real.
