Features to look into for Polycarbonate greenhouse kits

There are two types of panels used in Polycarbonate greenhouse kits. Knowing more about them can make you choose the design that will work in your location and with your gardening plans.

Single wall Polycarbonate design

The recent panel designs for the greenhouse have become more sophisticated. Gone were the days when greenhouse panels only consist of either glass or clear plastic.

The thick plastic material of Polycarbonate makes the single Polycarbonate wall unbelievably strong despite its being lightweight. The clear feature of the panels mimics glass in some ways, making them doubly attractive with none of the issues usually confronting glass panels.

Frosty weather is kept at bay by the single panels making them ideal for winter gardening. They are usually included in greenhouse kits and not sold for single custom projects.

Extending the planting season can become possible when the chosen greenhouse model is one that has single Polycarbonate panels.

Multi-wall Polycarbonate panels

The double or triple wall, often referred to as the multi-wall Polycarbonate panel, is the most common type used in greenhouse kits. The kit includes perpendicular support where the two or double layers of Polycarbonate sheeting are attached. This creates flutes or hollow spaces that provide insulation through their action of holding in the air. Choosing between small or large flutes makes no difference because there is only a small margin in their performance of holding in the air.

The air can only begin to circulate if there is a large air space. Air movement inside the flutes can affect insulation. However, triple or quadruple panels provide the flutes with additional layers which result in enhanced insulation.

An 8mm thick double wall will obviously offer less insulation than a thicker triple wall of the same circumference. Just remember to go for quality Polycarbonate greenhouse kits if you want one that is extremely strong and durable. High-quality Polycarbonate greenhouse designs usually offer ten years warranty periods.
