Greenhouse Cladding

Definition - What does Greenhouse Cladding mean?

Greenhouse cladding is a term used to describe the cover material of a greenhouse. Given that the cladding materials used to cover a greenhouse can greatly influence the level and the quality of radiation the crops are exposed to, and ultimately the crop yield, they are an important aspect of greenhouse design.

The greenhouse cladding is an essential component of the growing environment inside. Popular materials used for greenhouse cladding are glass and hard or soft plastic sheeting.

Another term for greenhouse cladding is greenhouse siding, or greenhouse glazing.

MaximumYield explains Greenhouse Cladding

Managing a greenhouse is not easy and the cladding determines the type of greenhouse you are managing. During the greenhouse cladding selection process, things to factor in include: the price, the durability, the weight of the covering, how easy it is to repair or replace, how much light can be transmitted through it, and how much energy moves through the material.

There are various materials to choose from for greenhouse cladding. Glass, though the traditional option, when compared to plastic, is more fragile and easily breakable. Glass claddings also have low insulation values, allowing the temperature to change inside the greenhouse. This property of glass makes it ideal for humid or tropical climate areas. Though glass can also be used in cooler climates, its usage depends on the types of plants grown.

Polycarbonate sheets, another good greenhouse cladding choice, are known for their durability and lightweight properties. Since they have a lower insulation value, plastic sheets are a good medium for diffusing light for photosynthesis. With good heat insulation properties during cold temperatures and the ability to maintain a cool environment during warmer temperatures, polycarbonate sheets are ideal many different climatic regions.

Polyethylene films are another greenhouse cladding option mostly used by commercial growers. They are known for being durable, cheap, and low-maintenance. These sheets absorb heat better than glass claddings and are good for areas with tons of exposure to sunlight. They can also help growers save up to 40% of heating costs. With a three to five year life span, plastic films are ideal for regulated weather conditions and prolonging gardening seasons.
