Description:
Geotextile slip sheet provides a lightweight and cost-effective
separation when overlaying an existing roof system or an
incompatible insulation product such as polystyrene. The roll
size is 15 x 360 ft (4.5 x 109.7 m). The slip sheet is made
from 100% polypropylene fibers that are needle-punched to
form a dimensionally stable fabric. This slip sheet cannot be
used over gravel-surfaced or ballasted roofs.
The Geotextile slip sheet may be used over:
•
Smooth or granular surfaced built-up roofs
•
Modified bitumen
•
Coal tar pitch
•
Single-ply membranes such as PVC, CSPE (Hypalon),
etc.
•
Smooth sprayed urethane foam
•
Acrylic and aluminum coatings
•
Polystyrene insulations
•
Shingles
Refer to the “Getting Started” section of the Duro-Last ®
Specification Manual for additional information on substrate
separation.

Installation:
1. The slip sheet must be installed on a clean and smooth
surface, smooth side up.
2. Individual pieces must be overlapped 3 inches.
3. The slip sheet must be attached with Duro-Last
approved fasteners, and 3 inch (76 mm) metal plates.
4. Place fasteners in each corner and along the overlap a
maximum of 15 ft. (4.5 m) o.c.
5. Install a minimum of one fastener for curb or wall
sections less than 4 ft. (1.2 m) in length and a minimum
of two fasteners for sections between 4 ft. (1.2 m) and 15
ft. (4.5 m) in length.
6. When installing the slip sheet along the top of parapet
walls, more fasteners may be necessary.
Note:
•
The rolls should be stored elevated and covered to keep
them dry. Use tarps, if necessary, to protect from rain.
•
Only install as much slip sheet as can be covered by the
roof membrane by the end of the day or onset of
inclement weather.
