Installation Guide
4
When installing the polycarbonate glazing make sure the UV coated side faces out. 
Loosen the edges of the protective film for installation. After the assembly is complete 
pull it off immediately. Do not leave the film on for any period of time in the sunlight. 
Several days of sunlight can burn the film firmly on the glazing.
Do not pull the film off right out of the box, otherwise you cannot tell which side has the 
UV protection!
Question: Does the greenhouse glazing need to be completely sealed?
 In principle: No.
We recommend that you seal the horizontal transitions where the glazing meets the 
aluminum profiles with a neutral cure transparent silicone. (Shown in the diagram below by 
dashed lines.) This will prevent water and dirt from entering the glazing slots.
Advantage: The greenhouse stays looking new as the seal prevents the formation of 
algae and buildup of dirt/dust inside the glazing.
During some weather 
conditions condensation can 
occur within the hollow 
chambers of the glazing. This 
is because the glazing 
chambers are not air tight. The 
condensation is purely 
aesthetic and cannot be 
avoided.
The condensation/water vapor 
will not damage the glazing, 
even at freezing temperatures. 
Warning: Use only neutral cure silicone, otherwise it may lead to stress cracks in plastic 
glazing. This is the most common silicone sealant.
Neutral cure silicone is available in most hardware stores. We recommend Boss 399. 
You can purchased Boss 399 directly from us, just call 1-877-760-8500.
Cleaning and care:
To wash the greenhouse use plenty of water, a car wash brush and a little detergent.
!!!Note: Important information for glazing!!!
Suggestion: If you plan on disassembling and moving you should mark the UV side of 
each panel before installation. A small circle in a lower corner with a permanent marker 
will work well.
