CRI 105, its residential carpet installation standard, has separate sections for broadloom and carpet tile. Broadloom seams, cushion and installation method depend on the product; carpet-tile backing and layout methods also vary, so CRI directs installers to the maker's instructions. Compare the specific system's floor preparation, seams, cushion or adhesive, transitions and replacement terms before buying.
The choice is about format and installation, not fiber alone. Broadloom is planned around room dimensions and seam placement; carpet tile is laid out as separate modules. Compare both using the actual product, floor condition and installation plan.
Compare the format
| Format | Layout, installation and floor checks |
|---|---|
| Broadloom | Plan roll sections, pile direction, pattern alignment and seams. The product may call for stretch-in over cushion, direct glue-down, attached cushion or another approved method. Match cushion, adhesive, subfloor preparation and transitions to its instructions; ask where seams can go and how the installation method handles a repair. |
| Carpet tile | Plan the tile pattern and direction specified by the product. Backing and attachment vary; CRI lists monolithic, ashlar and quarter-turn layouts. Match the backing, adhesive and floor condition to the product instructions. Some modular systems support replacing individual tiles, but verify match availability for the specific product. |
CRI’s Residential Carpet Installation Standard 105 provides separate installation sections for broadloom and residential carpet tile. It calls for planning broadloom seams and states that tile installation varies with size, backing and method, so manufacturer instructions govern.
Check replacement and floor compatibility
CRI describes pressure-sensitive adhesive systems for carpet tile that can be engineered for removal and replacement, but adhesive recommendations differ by tile backing. FLOR is one specific example: its FAQ describes removable, rearrangeable tiles and allows certain layouts over clean, hard, dry flooring. FLOR says its tiles are not recommended over carpet or padded flooring. Those conditions apply to that system; they are not a blanket rule for every carpet tile.
Make the quote comparable
Ask each installer to list product and backing, room measurements, seam or tile layout, floor preparation, cushion or attachment method, moisture requirements for the selected system, transitions, old-floor removal, disposal, labor and warranty terms. CRI’s residential installation tips recommend using qualified installers who follow CRI 105 and the carpet maker’s instructions. Compare carpet construction and cushioning in carpet fibers and padding, and compare hard-surface options in LVP, laminate and engineered hardwood. Browse flooring guides.

Common questions
What is the difference between carpet tile and broadloom?
Carpet tile is cut into separate units during manufacture and has an applied backing. Broadloom is planned and installed in wider sections, where seam layout and the selected installation method matter.
Can carpet tile be installed wall to wall?
Some residential carpet-tile products are intended for wall-to-wall layouts. Check the product's allowed locations, backing, adhesive and installation directions; FLOR, for example, lists both custom rugs and wall-to-wall layouts for its system.
Can I replace one carpet tile if it is stained?
Some modular systems allow an individual tile to be removed and replaced. CRI 105 says tile backing and installation methods vary, so check the exact maker's instructions and availability of matching replacement material.
Do carpet tile and broadloom use the same padding?
Not necessarily. Broadloom may use separate cushion or an approved adhesive method, while tile systems have product-specific backing and attachment. Follow the carpet and installation-system instructions.
