outdooR SyStemS utilizing a membRane Roofing mateRial
1. After the walk-in is completely assembled,
place the curb face down on top of
the ceiling sections (curb is fastened
to crate base during shipping and
must be removed and installed prior to
membrance roof installation). To ensure
proper opening alignment, mark the
outside portion of the curb on the ceiling
sections with a marking pencil.
2. Remove the paper from the gasket and
position the curb, gasket side down, on
the pencil line. Press down firmly. Note:
Movement of the curb is very difficult
after the gasket adheres to the ceiling
section. Refer to Figure 1.
3. Lay the membrane roofing material
over the walk-in ceiling sections and
curb leaving a six inch overhang
on all four sides of the walk-in.
Using an utility knife, cut a hole in
the membrane roof approximately
1-1/2” in from the edge of the
opening. (The resulting hole in the
membrane will be smaller than the
ceiling opening). Fold the 1-1/2”
membrane flaps into the opening,
notching the membrane around
the locators and divider. Use either
sheet metal screws, caulk, glue,
etc. to fasten the membrane roofing
material to the inside edge of the
curb frame. Refer to Figure 2.
