The strength of our greenhouses is one of the reasons customers choose us.
One of the reasons customers choose our greenhouses is the strength and ability to meet high wind and snow loads. The first thing to know is we have a standard 32 pounds per square foot for snow and 85 mile per hour wind loads but we can upgrade the loads as needed. With engineering and upgraded glazing options, we can upgrade both of these load ratings to a maximum 140 mile per hour winds and 100 pounds per square foot for snow.
Questions to Think About:
- What are the wind and snow loads in your area?
- How many seasons do you want to use the greenhouse?
- Do you have an easy pathway to access the greenhouse in winter if needed?
- Are there nearby buildings or trees that might cause high impact snow dropping on the greenhouse?
These are all important questions that your Greenhouse Expert will ask during your buying journey.
If a permit is required, we partner with our engineering firm who supplies sealed drawings within the acceptable guidelines. In many cases, the loads can be increased with some extra supports if a permit is not required. We increase the strength of the greenhouse by adding bracing, purlin supports, trusses or upgrading the frame to a tubular option.
Some General Guidelines:
- For heavy snow, we recommend our Cape Cod model as the high pitched roof (12/12) allows snow to simply slide off.
- If you live in a particularly windy area, ask us about upgraded roof vents as these require a stronger opening mechanism.
