What is the best polycarbonate for a greenhouse?
To build a high-quality greenhouse in your backyard most gardeners prefer translucent polycarbonate glasses. The type of colour and width of polycarbonate one should choose will affect its protection from UV rays and it can also increase or decrease its temperature inside the greenhouse.
Polycarbonate glasses come in two divisions which are honeycomb and Monolithic glasses. Honeycomb is a transparent hollow material that is placed on the inner side of the glass and sandwiched between large walls of polycarbonate. It weighs very little and fifteen times lighter than the normal class which makes them easy to replace and they are very flexible for creating complex-shaped structures.
Monolithic has a light transmission of twenty-six percentage and they don’t have a cavity in between sheets. They look more like glass but only more durable and lightweight. They are known as profile glass because it can have a smoother bumpy surface at the same time and it is more aesthetic to watch. It provides more functionality and practicality but both are great for greenhouses so you can choose any single one of them.
How to install polycarbonate sheets on the greenhouse?
Polycarbonate sheets are used in two ways both for roofs and as walls. They are available in various sizes, colours, and profiles and you need to select whichever suits your greenhouse best. The most popular widely used polycarbonate sheets are roof sheets and the lifespan of polycarbonate sheets depends on the quality and the way they were fixed to the columns.
They can be cut with trimming scissors or with a cutting saw. The quality of the sheets are affected by the precision of the cut made, so try to make the cut smooth. All holes must be drill in the panel before installation and always check the manufacturing instructions about drilling the hole. Once you have cut the roof panels to the current frame you need to attach the polycarbonate sheets to the side of the frame by matching the angles of the wooden base and then seal it off with a silicone seal to make it waterproof and permanent.

This means if you even leave the garden for summer days the plants won’t get too hot. Some greenhouses also come with fans to prevent overheating of plants but it is considered a good strategy to buy a ventilated window greenhouse.
