DURO-GUARD® XPS FAN FOLD – P
Installation:
Duro-Guard XPS Fan Fold – P may be used
directly under the Duro-Last membrane.
Ensure that “bare” XPS is never in direct contact with the Duro-Last membrane. Refer
to the appropriate Duro-Last specification for slip sheet and cover board requirements.
Panels must be kept dry before, during and
after installation. Install only as much fan fold board as can be covered the same day with completed roofing.
Abut panel edges together and stagger joints of
adjacent panels.
Boards must be neatly fitted to roof deck and
around penetrations with no gaps greater than ¼ inch.
Refer to the appropriate Duro-Last roof system
specification and detail drawings for deck preparation and other requirements.
Precautions must be taken to ensure that new
concrete decks have fully cured and do not continue to release moisture.
