Building Ends on an MSS Structure

Posted on by

One of the beauties of a Multi Shelter is the flexibility of the ends. By building the ends according to your needs your new building can and will truly prove useful.

It is important to remember that you need to be very careful when you have one end closed and the other end open.

When one end is closed you could potentially create a “parachute effect” (trapping air, creating lift) and put a lot of added stress on your building and especially the cover. Call us to discuss ways of minimizing this if your circumstance really would require one end open and one end closed.

When planning ends, it is important to have sufficient vertical framing to support wind load, doors, fans, etc. The spacing between the vertical framing will be determined by the amount of opening space required for the doors, etc.

It is important to remember that where ever possible, framing needs to go from top to bottom. In the event of large openings, the related framing will need to be doubled or tripled.

It is also important to remember that when you are covering your end with tarp, the top end of the cover is sandwiched between the wirelock channel and the hoop.

When you are covering with plastic, you will be fastening the top end inside the channel with the roof cover even if your roof is a double layer.

Large Greenhouses

Posted on by

We have a variety of widths and lengths of greenhouse structures from which to choose.

If you’re just trying to get a head start on the garden vegetable season (and maybe extending the growing season by a couple of weeks) consider our free-standing structures which use just one layer of poly.

If your intent is to grow all year round and heat the greenhouse then you should be looking at our greenhouse packages that offer a double poly roof, inflator fan kit and roll-up sidewalls for better heat efficiency.

COLDFRAME vs. GREENHOUSE

A COLD FRAME usually has a single plastic covered structure and used as a season extender
A GREENHOUSE usually has a double plastic cover with air in between and sides that roll up for year round use for better heat efficiency.

AVAILABLE OPTIONS

  • Custom widths, heights & hoop spacing
  • Roof vents & forced ventilation packages
  • Various types & sizes of doors with end framing priced separately
  • 8mm polycarbonate sheeting for roof and/or ends
  • Roll up sides for natural ventilation & reduced condensation
  • Cross ties for added rigidity, hanging baskets or crop support

Giving Back Greenhouse Opportunity

Posted on by

Multi Shelters values working with communities to help with charity and non-profit situations needing an extra boost of help, that we can give back whenever possible.

We have a wonderful opportunity coming up next week that we would like to share with you. Norm has been working closely with Johnny Theriault School and the community of Aroland First Nations, north of Thunder Bay. They are receiving a 20×48 Greenhouse for the school to use for teaching, and the community for fresh food. The community is quite excited for this opportunity and we are grateful to be part of the anticipation.

We would like to thank Breakfast Club of Canada for the opportunity of partnering with them to supply this greenhouse project. Norm will have to opportunity of meeting with the children and will be able to explain how this greenhouse will be used to produce some local fresh food.

We feel very grateful and fortunate to be involved with projects like this.

Greenhouses 101: Climate and Air Effects on your Structure

Posted on by

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.
