Roofing or Reroofing

Plasti-Fab FanFold has multiple uses on new roofs such as protecting expanded polystyrene insulations from direct contact with membranes, added membrane protection for high traffic roofs or as an added shield to protect membranes from damage due to hail and the harmful effects of the sun. FanFold cushions the membrane with its EPS core and protects membranes with its laminated/branded thin film on both sides.Simply apply FanFold above or below the roof membrane using approved fastening methods, then finish as specified. FanFold is easy to use in a roof recovery system which saves considerable time and labour costs. FanFold includes an EPS core which cushions the membrane while the laminated/branded thin film on both sides provides a smooth finish for application of the membrane.

Protection Board

Damaged dampproofing or waterproofing membrane is often the cause of foundation leakage which can be expensive to repair. FanFold can be applied over the top of the membrane to protect it from damage during backfill placement. Plasti-Fab FanFold underlayment provides a drainage plane directing moisture toward the drain tile before it reaches the foundation wall further reducing the chance of water infiltration into the basement.FanFold underlay can easily be installed over either sprayed-on or peel and stick membranes. To install, just attach FanFold using any adhesive compatible with foam plastic insulation and start backfilling.

Re-siding Application

The most common way of enhancing a home’s beauty & resale value is by re-siding. FanFold by Plasti-Fab® provides a continuous insulating underlayment for new siding. Place FanFold directly over the existing exterior finish and attach using fasteners that will penetrate through the existing siding to a nailable substrate. The grid lines assure that the siding is placed level as well as providing straight lines for cutting around door and window openings.

New Construction

Use FanFold as an insulating underlayment beneath new siding on exterior walls. Install FanFold underlay as a sheathing material attached directly to the studs or over wood sheathing using nails. All types of exterior finishes can be used and are attached through FanFold underlay and into the studs. FanFold by Plasti-Fab® used beneath siding provides a continuous insulating underlayment that reduces air infiltration, reducing heating and cooling costs.
