Norm did a presentation at the Guelph Organic Conference on Greenhouses 202: Making sure your structure survives the elements. The presentation is broken into three parts for easy viewing, the last section of which is the Q&A. These tips apply for greenhouses, storage buildings, livestock shelters, really anything we sell. Key Points Covered in the presentation:

1. Some basic principles of engineering so that the forces exerted on the buildings could be better understood.
2. The many components of anchoring. Anchoring prevents a structure from settling under snow load, prevents lifting under aerodynamic forces and prevents shifting with wind forces.
3. The similarities of an airplane wing to the shape of a structure. What happens when surfaces become bigger, wider. lower and higher.
4. How uneven loads can happen and how to prevent them.
5. The proper procedure to removing excessive snow load

Greenhouses 101: Climate and Air Effects on your Structure

You might be wondering, How does air volume affect the climate in a greenhouse? There also is the matter of air changes. What is the connection between shape and aerodynamics? You need to make sure it stays put.

There are 3 forces on every building which need to be considered if you want it to stay where you put it and in the shape you built it. There is down force (usually from snow build up), up lift (by wind) and lateral shift (both wind and snow). Mother nature is not restricted by lack of patience and will work away at any vulnerabilities in the structure, often without notice until it’s too late. There must not be any wiggle room that the weather can work on these vulnerabilities or things will come loose, unstable, and wear out faster..

There simply is no such thing as too many anchors. There are also various tips we can give you for ensuring that the plastic is tight enough to avoid wrinkling and flapping about, while balancing the issues of it being too tight. This can easily extend the life of your roof cover.

We also advise, especially this time of year, to cover the structure as soon as you can as the more snow you have on that spot which has to melt, the more moisture you will have in the building. The more moisture you have in the building the more condensation issues you will have. You want to give that ground the most time possible to dry up before you need to start using the building.

Contact us for more tips and considerations for building a structure that will stay put and have a longer life, we would be happy to help you.
