• Q. 6mm or 4mm polycarbonate what is the difference

The polycarbonate panels play a crucial role in the agricultural market place. Their ability to allow abundant light into the interior spaces, light weight and easy to install properties have been the key advantage for their popularity, especially in greenhouses.  A hard and durable greenhouse can offer a long-term cost saving, and they are not only used to protect the plants,but it is also used as a state-of-the art garden feature. There quite a number of polycarbonate profiles available in the market,however, when it comes to the insulation value of polycarbonates, a twin-wall polycarbonate sheet greenhouse is preferred. As a nation, we have long history of gardening enthusiasm. In recent years, we have seen numerous new traders starting importing greenhouses into new zealand. However, majority of the new traders are bringing the 4mm thick polycarbonate greenhouses, due to their cheaper retail price. After seeing plenty of disappointed owners of 4mm greenhouse - a lot of these doesn't last for one season, we decide to write this information to help you make the right choice when you choose a greenhouse. 

1. Insulation "R-value" is a commonly used term to measure a material’s energy conserving (or insulating) properties. It is a measure of resistance that a material has to the flow of heat. The below r-values reflect real world outdoor situations.The more energy conserving a material is, the higher it’s r-value.

Polycarbonate 4mm 1.3

Polycarbonate 6mm 1.6

The 50% greater air gap between the walls, creates 20% effectiveness in heat protection. 

2. Strength.   6mm sheet is 50% thicker than a 4mm sheet. Also the aluminum profile are made thicker and wider to accommodate the extra thickness. 

3.Light diffusion.   6mm polycarbonate sheets have 5-10% less light transmission than 4mm ones. This might sound like a reduction in light transmission, but it is diffused by the polycarbonate, which means light gets more evenly distributed to what would be darker areas in your greenhouse.

4. Lifespan.   In general Greenhouse manufacturers 4mm is the entry level greenhouse, most of these are made aiming for the lowest cost. Thus majority of these we have seen from nz greenhouse market, are made from recycled material. Some of the 4mm polycarbonate sheets are not even uv treated, which won’t last few months under nz weather, our Cliamapod material both 4mm and 6mm UV protected.

  • Q. How does the greenhouse ship to me?
The greenhouse is shipped via Mainfraight  in 4 or more large boxes, the heavyest one is 380lb. Other: like Fedex UPS wont handle this large boxes. The exact number of boxes varies depending on the kit that was ordered.

  • Q. Do you sell larger greenhouses than on your website?
Yes, you may request additional information on the custom larger models from our customer service representatives. (360)-241-1624
  • Q. How strong is a ClimaPod greenhouse?
Europe’s standards are higher than those in the US, and the TUV Europe testing lab which is equivalent to UL has tested the product and certified it as being strong and safe. The incredible strength of the greenhouse comes from its excellent engineering and the high quality of plastics and aluminum used.
  • Q. What is their snow load capacity?
The load capacity is roughly 50 lbs per square feet. Never the less, we do recommend that you brush the snow off the roof whenever it gets over a foot.
  • Q. Where should I locate my greenhouse?
The selection of a site involves taking into consideration three importantly factors:
the most desirable location should be shaded by deciduous tree(s) or lacking shade draped with an external shade cloth over the greenhouse;
the site should also be sheltered from the wind by a tree(s) or some other barriers;
the site should be level and allow for good drainage.
  • Q. How do I secure the greenhouse?
The greenhouse should ideally be attached to some sort of foundation, in order to keep it secure, and it should be preferably something heavy/solid.
  • Q. What kind of greenhouses does ClimaPod offer?

ClimaPod Greenhouses are all glazed with Polycarbonate panels and framed by Aluminum profiles.

  • Q. What is polycarbonate?
Polycarbonate are a particular group of thermoplastic polymers. Their superior features compare to other polymers (temperature resistance, impact resistance and optical properties) position them between commodity plastics and engineering plastics.
  • Q. What makes a polycarbonate greenhouse better than glass?
Polycarbonate panels are virtually unbreakable. It is a big plus concerning their longevity as also their safety, especially important when younger children or the elderly are involved.
The light weight of the panels – less than 2-3 lbs – is another advantage that affect the convenient of assembly or even re-location option (assembled 9’x12′ greenhouse is less than 250 lbs).
In addition the Polycarbonate panels protect everything inside the greenhouse from the harmful UV rays, either it is shelving, pots, tools or your skin.
  • Q. What are Clear Polycarbonate panels?
Clear Polycarbonate panels are unique for ClimaPod Clear greenhouses. They combine the visual appearance and functional effects of glass with the advantages of polycarbonate greenhouse.
These are solid panels that have about 90% light transmission which bring flowers and plants inside the greenhouse to be part of your garden landscape and you can see everything within, like glass. Your plants will enjoy maximum light exposure.
On the other hand, Clear polycarbonate panels are fully safe since they are virtually unbreakable, and their light weight (less than 2-3 lbs) makes the assembly process easier and more convenient.
Q. What is R-Value and K-Value is?
Greenhouse Covering Insulation Comparison
Compare the insulation rating of Solexx to other greenhouse coverings on the market. The higher the R Value, the better the material insulates. Solexx even beats 8mm triple wall polycarbonate! A greenhouse with good insulation has many benefits: 
Traps the Heat: Keep frost at bay to extend the growing season
Better Heat Retention: Save energy costs when you want to heat
Less stress on plants: As outside temperatures quickly drop at night, the temperature inside the greenhouse changes slowly
The better the insulation, the lower the condensation
 Right now we offering only 6mm and 4mm
R-Value - the measurement of 'insulating ability' of the material. The higher the R-Value number the greater the insulation value.
U-Value - the measurement of 'heat loss' through the material. The lower the U-Value the less heat is escaping. 
*Independent testing, Solexx with caulked flutes.
  • Q. What sizes are available for the ClimaPod greenhouses?
Hobby series come with 9’ width and 12’ depth.
 Spirit series come approximately with 7' width and 12’ depth.
Passion & Virtue series come approximately with 9’ width and 14’ depth.
Clear models come in 6’x8’, 8’x10’, 8’x12’.
  • Q. Is it possible to enlarge your greenhouse?
Yes, ClimaPod Greenhouses can be assembled together. As long as you secure them properly, you can put together as many greenhouses as you want.
  • Q. What accessories are available for the greenhouse?

  • Q. How long will a Polycarbonate greenhouse will last?
ClimaPod is using Polycarbonate which is UV protected therefore there is no yellowness, turbidity or disintegration for at least 10 years.
  • Q. Can the frame rust?
No. Our Aluminum is rust resistant. The steel parts like the base are galvanized.
  • Q. How to choose a greenhouse site?
If possible, locate the greenhouse where it will receive at least 6 hours of direct sunlight during the winter months. Avoid a site that is shaded by buildings or trees. A good site would also be sheltered from high winds. Easy access and close water and electricity are also important. The recommended greenhouse’ position is with its ridge running east and west so its length will face the sun during most hours.
  • Q. What kind of surface does the greenhouse need?
The greenhouse must be positioned on a flat level surface. It can be either a concrete, gravel, strong wood platform, or a flat ground that was leveled carefully.
  • Q. How should I anchor a ClimaPod greenhouse?
The greenhouse should be anchored to a firm surface.
  • Q. How do I clean the greenhouse?
Use a mild detergent solution and rinse with cold clean water. DO NOT use acetone, abrasive cleaners, or other special detergents for cleaning as they can remove the UV resistant layer on the polycarbonate.
  • Q. How do I ask for replacement/missing parts?
