Stretch-In Carpet, Explained

Stretch-in carpet is a common broadloom carpet format installed using perimeter anchoring and tension. This page explains what stretch-in means and the specs you’ll commonly see on technical data sheets — reference-only, no product or install advice.

Plain English Spec Definitions Evergreen

What Is Stretch-In Carpet?

Stretch-in is an installation format for broadloom carpet where the carpet is held in place at the perimeter and installed under tension. It’s commonly paired with a separate carpet pad, which is specified as part of the overall system.

On spec sheets, stretch-in products are often described as “broadloom” with construction details. The installation system (pad + perimeter anchoring) is usually treated as a separate system spec rather than a single “carpet-only” number.

How Stretch-In Differs From Glue-Down And Tile

Stretch-in carpet is built around a system approach: broadloom carpet plus a separate pad and perimeter anchoring. Because the carpet isn’t bonded across its entire surface, spec sheets often focus on construction and wear-related specs rather than adhesive-related requirements.

Glue-down and tile systems tend to emphasize different sheet details (like adhesive compatibility or modular backing systems), while stretch-in systems often emphasize the carpet’s pile and fiber construction and the backing build.

Common Stretch-In Terms You’ll See

  • Broadloom (roll carpet format)
  • Pile Height (surface yarn height)
  • Face Weight (fiber weight per area)
  • Density (how tightly tufts are packed)
  • Twist Level (yarn twist, often for cut piles)
  • Backing Construction (primary/secondary backing)

One-sentence explanations of common spec-sheet items, with links to deeper spec pages.

Spec What It Means (1 Sentence) Where It Appears Deep Dive
Fiber Type The material used for the carpet yarn (which affects feel, resilience, and maintenance characteristics). Construction Fiber Type Explained
Pile Height The height of the carpet yarn above the backing (a surface profile spec, not a durability guarantee). Construction Pile Height Explained
Face Weight The weight of yarn on the face of the carpet per square yard (often listed as oz/yd²). Construction / Performance Face Weight Explained
Density A measure of how tightly the carpet tufts are packed, which can relate to how the surface holds up under traffic. Performance / Construction Density Explained
Twist Level How tightly the carpet yarn is twisted (often listed as TPI), which can affect texture change in many cut piles. Construction (sometimes) Twist Level Explained
Backing Construction The layers on the underside of the carpet that help lock yarn in place and support the carpet structure. Construction Backing Construction Explained

FAQ

Short Answers. Reference-Only.
What Is Stretch-In Carpet?

Stretch-in carpet is broadloom carpet installed by stretching it over perimeter anchoring (often tack strip) and securing it at edges, commonly over a separate carpet pad.

Is Stretch-In Carpet The Same As Pad?

No. Stretch-in is an installation format. Pad is a separate layer underneath many stretch-in installations and is usually specified as part of the overall flooring system.

How Is Stretch-In Different From Glue-Down?

Stretch-in relies on perimeter anchoring and tension (often over pad), while glue-down relies on adhesive bonding to the substrate and commonly uses different backing/adhesive considerations.

What Specs Matter Most For Stretch-In Carpet?

Common specs include fiber type, pile height, face weight, density, twist level (for many cut piles), and backing construction. Pad/cushion is often specified separately as part of the system.
