Sun Screen Fabric
This example is for a 6'x8' greenhouse. Materials can be varied to
construct other sizes. Pressure treated lumber is recommended.
Materials:
Two 6'x25' rolls Sun Screen Fabric
Four 4" x 4" x 8' posts
Twelve 2" x 4" x 8' lumber
Five 2" x 4" x 10' lumber
Five 1" x 4" x 8' lumber
One pair 3" x 3" square door hinges
Four pounds 16d galvanized box nails
One-half pound 4d galvanized box nails
Seven packages of Wood Fasteners
Four sacks concrete mix
Instructions:
1. Set four corner posts 2' deep in concrete, align and plumb.
2. With string and line level, mark tops of posts level and cut off.
3. Cut and nail a 2" x 4" band around the outside of the posts flush
with the post tops. Do the same at ground level.
4. Nail a 2" x 4" x 8' rafter plate on top of the posts and flush with
the outside of the band on the two 8' sides.
5. Nail two 2" x 4" x 8' to the inside of the top and bottom bands
to form a 2' door opening in the center of one of the 6' ends.
6. C
ut 1
0 rafters, 50 1/4" long at the longest point with a 45˚ angle
on each end.
7.
Use a 1" x 4" x 8' as a ridge and install the rafters in pairs, one
pair every 2'. The pair over the door should nail to the studs on
either side of the door.
8. Starting at the door opening, wrap the inside of the walls with
Sun Screen Fabric, fastening it to the top 2" x 4" band with
Wood Fasteners. Then fasten to bottom band, corner posts and
studs at door.
9. Cut two 6' x 8' pieces of Sun Screen Fabric for the roof.
Lay o
ne piece 6" past the ridge, fasten to the rafters on the op-
posite side, stretch down and fasten with Wood Fasteners
to ridge, rafters and rafter plate. Repeat on the other side.
Trim off excess fabric along rafter plate.
10. Cover gable ends with Sun
Screen Fabric. Fasten with
Wood Fasteners and trim
off excess.
11. Construct door from four
1" x 4" x 8' and 28" x 71"
piece of Sun Screen Fabric.
Cut: Two 1" x 4" x 28"
Two 1" x 4" x 57"
Two 1" x 4" x 21"
Two 1" x 4" x 64"

Using similar tools and materials as those for the greenhouse,
a simpler and more basic structure can be fabricated to provide
shade over a 6’ x 8’ garden space (see diagram below). Materials can
be varied to build other sizes. Constructed entirely out of pressure
treated 2x4 lumber, depending upon short or long-term needs, posts
may not need to be set in concrete. This frame is primarily designed
for attaching Sun Screen Fabric across its flat top; however, side
panels may be added to block the sun when it is at a low angle.
