Can your greenhouses handle heavy snow?

Yes, our greenhouses are designed to withstand a minimum of 32 pounds per square foot.

Over the years there is one thing that makes us stand out from the rest. Our standard greenhouses are rated to carry a snow load of 32 pounds per square foot and 85 mile per hour
winds at minimum. We have designed greenhouses to handle over 100 psf for snow and 140 mph winds. This is well respected in our industry and a source of pride for our staff.

Adding a little heat to the  greenhouse when you know a big snowstorm is coming is always a good idea.

How much snow equals our standard 32 pounds? About 2-3 feet of medium pack snow. If the snow weighs 10 pounds per cubic foot and there is 1.5 feet of snow on the roof, each square foot is getting 15 pounds of pressure. If the snow has a high moisture content or is mixed with ice, the weight load increases. 

The greenhouse wind-load upgrades can be engineered with the specifications of your local area. If a permit is required, we can supply sealed drawings with the acceptable guidelines. In many cases, the loads can be increased with some extra supports if a permit is not required.
