Glue-Down Carpet, Explained

Glue-down carpet is a common broadloom format where the carpet backing is bonded to the substrate using adhesive. This page explains what glue-down means and the specs you’ll commonly see on technical data sheets — reference-only, no product or install advice.

What Is Glue-Down Carpet?

Glue-down is an installation format where broadloom carpet is bonded to the substrate using an adhesive system. Instead of using perimeter tension like stretch-in, the carpet’s backing is held by the adhesive bond across the floor area.

On spec sheets, glue-down carpet is still described primarily by construction details (fiber, pile, backing), but glue-down installations may also reference system-related requirements where the backing and adhesive work together.

How Glue-Down Differs From Stretch-In And Tile

Glue-down broadloom is built around adhesive bonding. Because the carpet is held by a bond rather than perimeter tension, glue-down systems often emphasize backing construction and system compatibility.

Stretch-in systems commonly pair broadloom with a separate pad and tension-based anchoring. Carpet tile is modular and typically uses different backing approaches and installation methods. The core idea is the same: the format changes what parts of the system matter most.

Common Glue-Down Terms You’ll See

  • Broadloom (roll carpet format)
  • Backing Construction (primary/secondary backing)
  • Tuft Bind (how firmly yarn is held by backing, when listed)
  • Dimensional Stability (movement under test conditions, when listed)
  • Density (tuft packing / structure)
  • Face Weight (fiber weight per area)

Glue-Down Carpet Specs Glossary

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
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
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
Pile Height The height of the carpet yarn above the backing (a surface profile spec, not a durability guarantee). Construction Pile Height 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

FAQ

Short Answers. Reference-Only.
What Is Glue-Down Carpet?

Glue-down carpet is broadloom carpet installed by bonding the backing to the substrate with adhesive, rather than stretching it over perimeter anchoring.

Is Glue-Down Carpet The Same As Carpet Tile?

No. Glue-down broadloom is roll-goods carpet bonded to the floor, while carpet tile is modular and typically uses different backing systems and installation approaches.

How Is Glue-Down Different From Stretch-In Carpet?

Glue-down relies on adhesive bonding across the floor area, while stretch-in relies on perimeter anchoring and tension, usually over a separate pad.

What Specs Matter Most For Glue-Down Carpet?

Common specs include fiber type, pile style, face weight, density, and backing construction. Some spec sheets also list tuft bind or dimensional stability depending on the product and category.
