Understanding the Benefits of Different Types of Installation:
Stretch-In Installation: There are situations in which the installer will wish to utilize the stretch-in method. Its selection may be for one of the following reasons:
- Provides enhanced underfoot comfort, acoustical properties (i.e., higher noise reduction coefficients and higher impact noise ratings) when installed with a separate cushion.
- Increases thermal insulation (R-value).
- Can be used over floors that are unsuitable for glue-down.
- Corrective measures, such as seam repair, may be easier to perform.
- Removal costs usually are less than the removal of an adhered installation.
Stretch-In installations should be avoided in the following case:
- On ramps and inclines.
- Where office systems furniture and demountable partitions are utilized.
- Where heavy rolling traffic is likely.
- Where there is excessive humidity.
- When carpet has a unitary backing or other backing systems designed only for glue-down installation.
Direct Glue-Down Installation:
- Suitable for rolling traffic and ramp areas.
- Seams are more durable since there is no vertical flexing.
- Minimized buckling in buildings that have HVAC systems turned off for extended periods of time.
- No re-stretch situations.
- Facilitates access to electrical and telephone lines under floor.
- Practically eliminates incidences of seam peaking.
- No restrictions to area size.
- Intricate borders and inlays are possible.
- Usually less expensive.
Double Glue-Down Installation: This method combines the stability of direct glue-down carpet with the cushioning benefits of a separate cushion, stretch-in installation, as outlined below:
- Improves carpet appearance retention, under foot comfort and overall performance.
- Simplifies carpet bordering and inlaying.
- Suitable for wheeled traffic areas.
- No restrictions on size of area.
