Winter Storms and Maintenance 

With the upcoming storms in both Ontario and the east coast forecasted, we wanted to remind everyone: it’s okay, and even preferred that the buildings have some snow around them. 

This prevents the wind from getting under them and it also means that the height above the ground is less. This significantly decreases the aerodynamic lift.

As we’ve stated in our winter care articles and in the installation guide, there are things you can do to prepare your building to withstand the storms as best as possible. Taking extra steps during the ‘worst case scenario’ situations can often make all the difference and help your building stay standing.

Please don’t hesitate to contact us if you have any questions about any of these situations. Good luck and stay warm! 

Greenhouses 202: Making Sure Your Structure Survives the Elements

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
