Aluminum Frame Installation
Check that the foundation is level and square. If your
foundation is larger than the greenhouse, mark a line on it
with a pencil or with a chalk line. Take a caulking gun and
put in a tube of caulking. Cut 1/4” off the top at a 25-degree
angle. Then put a bead of caulking on your foundation
approximately 1” in from the outside of the foundation or
the marked line. DO NOT CAULK THE DOOR OPENING.
Measure your door opening in the front.
1. SIDE BASE/SILL
Lay down the aluminum side base/sill flush with your base or on the line you have marked
out. Push down on it so that the caulking squeezes out. (See Step 1 Detail, page 14)
2. FRONT GABLE-END
Stand up the door end, flush with your base or marked line. Slide up one bolt in the bottom
of curved glass end bar (front). Take the end bar and push it into the side base where it is
notched. The back of the bar lines up with the first slot in the side base/sill. Slide the bolt
down and fasten it. When you are lined up and in the right place, screw down the front
base/sill using the screw holes that are already there. Then put one screw in the side base to
hold it in place. When you have fastened down the front, it should stand by itself. (If it is
windy, you will need another person to hold up the front, or you can use a stepladder so that
the front can lean against it.) (NOTE: after the greenhouse frame is up, double check for square
and plumb. Seal behind the poly bar, against the wall and the ridge, then put in all the screws.) (See
Step 2 Detail, page 14)
3. BACK GABLE-END
Follow the same procedure for the back gable-end as you did for the front. When you have
bolted it to the side base and it lines up flush with your base/sill or marked line, then you can
proceed. Fasten the base/sill down to your foundation with the screws that are provided.
When fastening the side/base sill to the foundation, be sure that the base is straight.
(See Step 3 Detail, page 14)
4. RIDGE
Before you slide in the ridge, put one bolt in the top of each curved poly end bar. Take the ridge
(one person at each end) and slide it between the end bars on the top. You will notice the
punched-out slots in the bottom flange of the ridge. The slots on the end line up with the
bottom side of the poly end bar. Now slide in the ridge and slide the bolt into the ridge slot.
Make sure that the curved poly end bar is tight against the ridge – use a 7/16 flat wrench (at this
time you can temporarily fasten the ridge to keep it from moving around). (See Step 4 Detail, page 15)
4A. SEE APPENDIX A FOR TRUSS ASSEMBLY INSTALLATION FOR
GREENHOUSES LONGER THAN 16 FEET.
5. CURVED POLY BARS WITH SLIDERS (1, 2, 3 etc.)
Each Poly Bar (with a vent frame slider) is marked with a number (1, 2, 3 . . .) to correspond
with the number on the ridge. Slide the bolt into the top of the Poly Bar and line it up with
the slot in the ridge. Move up the bolt and fasten it. Do the same for the bottom of the
polybar. Slide in the bolt, lift up the end, and push it into the side base/sill as far as you can.
Then bolt it on. Do this for all the Poly Bars with sliders and numbers. The end of the bar
should be tight to the base. (See Step 5 Detail, page 16)
