Angles to Cut for a Hexagonal Greenhouse

Sides - Frames

• The angles of the joints of the frames of the six sides are all 90 degree angles. This is because the frames are rectangular.

Sides - Panels

• For a hexagonal greenhouse, the angles of the joints of the panels -- the sections within the frames -- of the six sides are all 90-degree angles as is true of traditional rectangular greenhouses. Different angles can be used for a non-traditional look. The structural integrity of the greenhouse will not be compromised so long as you do not damage the frames of the six sides.

Roof Trusses

• The angle of cut of the three members of each of the six roof trusses is 120 degrees. Each set of three will then fit together to make a triangular frame for each roof panel.

Roof - Triangular Panels

• Cutting angles on glass is a specialized job. The job is far easier with polycarbonate. As do-it-yourself experts Albert Jackson and David Day point out, cutting glass is not usually necessary as suppliers will do it for you. The general principles, however, are the same. The angles vary according to the pitch, or the angle of the slope of the roof, and must be worked out with simple geometry depending on the dimensions of the greenhouse. If you live in an area that experiences high levels of snowfall, follow Ortho's advice and have a higher pitch as this prevents ice and snow buildup. This will mean the base angles of the six triangles will be greater than 60 degrees and the top angles will be less than 60 degrees.
