Infrared Plastic Coating

Another variation on greenhouse plastic is with an IR (infra-red) coating.

  • The IR plastic can reduce your heat loss by up to 20% over a regular double poly installation.
  • Even though this plastic has a hazy look to it, the light transmission properties are actually a couple percentage points better.
  • This plastic comes standard with an anti-condensate coating which means there will be less dripping in the greenhouse.

All of these features make IR plastic an attractive alternative for many people in spite of the fact that the cost is roughly  20% more then regular plastic. This plastic does not have an inside or outside.

The cell structure that the Infrared plastic is made from is significantly different from the regular plastic. This gives the plastic a much softer texture and feel and contributes to it not being as strong as regular plastic. This is why we suggest that it only be used as the inside layer of a double plastic installation.

The slight restriction for people with shorter greenhouses is that the IR plastic only comes in 100′ and 150′ rolls. You would either have a friend who can buy/use the extra or be prepared to “waste” some. There are also not quite as many choices for available widths as with regular plastic.

Solar Powered Inflator Fan Update & Alternative

We have been continuing to get many inquiries about solar powering the inflator fan for greenhouses and livestock buildings, which is used to put air between two layers of plastic roof cover. For the last year we have been experimenting with a solar collecting package to determine what is required, while we work to keep our interested customers updated along the way.

The first thing that must be emphasized, is that you MUST use a squirrel cage type of fan and not a propeller type. The propeller type can not continuously run against back pressure.

The output required will be determined by the size of the greenhouse or livestock building. Our regular 110 volt fan draws .25 amp and puts out 80 cfm. Some small buildings can use a smaller fan and some of the bigger ones require our double output fan which gives 130 cfm.

Our inflator fan works quite well going through an invertor. Any 12 or 24 volt fans which we have tried have been extremely noisy and therefore not feasible.

The biggest challenge which we encountered, is that the specific time the fan is needed the most for heat insulation, is also the time where there is the least capacity for generating power.

We used a single solar collector and a single battery and there was simply not a quick enough capacity for the battery to hold charge when we had several consecutive cloudy days in December/January

To add another solar collector to an already fairly expensive package, really becomes prohibitive and can deter from moving forward with it.

Based on this experience, we wanted to offer an alternative that balanced economy with feasibility. We have come up with a way where the extra roof plastic can be used on the inside of the structure.

This means that you would not need the inflator fan but still have the effect of double plastic with the air pocket for better heat efficiency. This system does require a bit of extra “fiddling” but the net cost will be a little less.

1. The structure is covered with a single layer of plastic just the same as you would if you were only doing a single layer.
2. Take the second piece of plastic inside the greenhouse and fold it double lengthwise.
3. This double plastic will be attached to the underside of the ridge using the same aluminum as you would use to fasten the plastic to the roll up pipe.
4. Next remove the purlins from the one side of the structure and after you have pushed over the plastic, reinstall the purlins under the plastic. You will be pushing the bolts through the plastic.
5. The plastic will be fastened with wirelock to the underside of the end hoops.

We have already had some customers try this out and are very happy with the result. Please call us with any questions or to discuss your specific application and situation where you might use this. We would be happy to help you with your project!

Lean-To Structures

We offer an option of lean-tos where the need, with limited space, for the shelter to be attached to the side or front of a bigger building

Pricing for the lean-tos are generally 60% of the price of the structure. You can see pricing and options on the various application pages and calculate it from there. Please don’t hesitate to call us for a more firm price if you have any questions.

All of the Multi Shelter Solutions structures use the 2 part hoop system bolting together in the middle with a continuous ridge. This allows any of our buildings to be used as a lean-to. The size of the lean-to is mostly determined by available wall height where it will be fastened To determine where to look for applicable information double the width of your desired lean-to (e.g. 10’ lean-to…look at 20’ wide, either regular, high or space saver)

To fasten a lean-to to the wall we can supply individual brackets for the top of each hoop if the support framing is consistent enough (55% cost of full structure) or we can supply a single sided ridge (60% cost of full structure)..

One point of extreme caution, you must be aware where snow typically comes off the building where the lean-to is being attached to. One of our “heavy duty” options may be required to provide the required security.

Igloo Round Structures

circle1

 We have a unique structure that we have started offering more often. It is a round dome structure, with our standard hoops around a circular ridge piece. We have taken to calling this our “Canadian Igloo” Structure. Plastic is put on in separate pieces so it’s not for the new greenhouse assembler. We have them being used for everything from seminar areas to storage, whatever you would like a unique application for!

Featured Add-On: Center Pivoting Gable Vent

We wanted to remind everyone of the center pivoting gable vent that we offer as a simple solution to the challenges of venting a building.

For venting to be effective, it has to be as high as possible. This is a cost effective alternative to costly roof vents.

Part of the window swings in and part of it goes out. Because of this

  • rain is never an issue
  • the window is easy to control even in extreme winds.
  • Incoming air is always deflected up to mix with the warmest air.
  • The tubular steel construction makes it both lightweight and resist twisting over time.

A continuous rope goes from the top of the window to a pulley at the ridge, down to ground level and back up to another pulley and then to the bottom of the window. By tying the rope off to an eye bolt on a gable post, this allows for very simple control from ground level.

Please don’t hesitate to call us for more details or with any questions you have about this option for your building!

Properly Venting a Building

Properly venting a building is a critical consideration when planning your building.

Getting rid of the initial ground moisture, quickly, when you have erected your new shelter is something many people do not think of. Quality air changes for plants or animals is something that automatically comes to mind. Getting rid of moisture is equally as important for storing your valuables.

Vent4Since warm air holds moisture and warm air rises, it is important to have venting capacity as high as is possible.

Venting through the roof, with individual turbines or a continuous roof vent, is the most effective but also the most costly.

This is only really necessary when you are in a very protected spot and there is a real need to keep the temperature down in a long building.

vent3Most medium length buildings that have the ends facing into the prevailing winds, can be adequately vented with gable end peak vents.

  • Make sure that these openings are as big as possible and as high as possible.
  • It is also important to make sure your “windows” can withstand the winds in your area.

Our centre pivoting gable vent has filled this requirement very effectively.

  • With part of the window going in and part of it going out, the wind can never get hold of it.
  • With the top and bottom rope through a double pully on the ridge, it is easy to maintain precise control over the opening area

As with all the other considerations, please do not hesitate to contact us with your specific set of circumstances and challenges
