a) Stretch-in Installation
b) Direct Glue-Down Installation
c) Double Glue-Down Installation
Stretch-in Installation
There are situations in which require the stretch-in installation. This method can be used 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 separate cushion
• Increases thermal insulation (R-value)
• Can be used over floors that are unsuitable for glue-down
• Patterned carpet are more easily matched
• 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:
• 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 incidents of seam peaking
• No restrictions to area size
• Intricate border and inlay possibilities
• Usually less expensive
Double Glue-Down Installation
• Combines the stability of direct glue-down carpet with the cushioning benefits of a separate cushion, stretch-in installation
• Improves carpet appearance retention, foot comfort and overall performance
• Simplifies carpet bordering and inlaying
• Suitable for wheeled traffic areas
• No restrictions to size of area
